What is a better investment, Bitcoin or Ethereum?

Ethereum.
Before I explain why, I need you to understand something. Bitcoin and Ethereum are at two completely different stages within their potential. They also do not share the exact same mission; therefore, you do have to understand their differences to form an opinion about which one has the biggest use.
Before we look at the coins in detail, let's start with the potential ROI (100% = 2x Original Investment).
Bitcoin’s current market cap is $193,165,354,468 in order for you to make 100% this number would need to double to just under $400 Billion.
Ethereum’s current market cap is $44,715,990,083 , roughly 1/5th of Bitcoins. In order for you to make 100%, the price would need to increase to just under $90 Billion. - This is obviously more probable.
This will not serve as the only variable in making a decision, we now need to break down their uses and differences.
Bitcoin
What is Bitcoin?
A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without the burdens of going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as honest nodes control the most CPU power on the network, they can generate the longest chain and outpace any attackers. The network itself requires minimal structure. Messages are broadcasted on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.
Peer-to-Peer (P2P): is a technical way of saying computers (peers) that are connected together via the internet.
Timestamps: are a sequence of characters that identify exactly when a certain event occurred, giving the exact time and date.
Hashing: is the process of compacting large quantities of data into smaller fixed sizes.
Proof-of-work: is the verification that the individual peer created the said hash
Nodes: are computers that are connected to the blockchain
Bitcoin is a first generation cryptocurrency, that was created in 2009 with the intention to become the currency of the internet.
Its Applications
Safe Haven
Being that billions of people are under the control of a broke economy or volatile dictatorship, Bitcoin is beginning to become a medium in which people within underdeveloped countries feel as a more secure place to store their value.
Remittances
The current operation costs roughly $600B annually, all at the expense of separated families. Bitcoin can now serve as a tool that operates the exact same way and only costs 1/10th of the price.
A transaction on the Bitcoin network also processes faster therefore giving the people a strong reason to make the switch.
Currency
Bitcoin is recognized as an asset, but can also be identified as an efficient currency in which people can buy and exchange with. With this being an application of Bitcoin, as the market continues to decrease in volatility, the use for Bitcoin will increase within businesses and everyday people that transact on a daily basis.
These are just a few, but for the sake of answer length, let’s move onto some of the scalability issues with Bitcoin that hinder my decision of choosing Bitcoin over Ethereum.
Bothering Issues with Bitcoin
Energy
A study from Digiconomist found that each transaction on the Bitcoin blockchain uses 236 KWh worth of electricity, this amount is enough to power 8 U.S households for an entire day.
Scalability
Energy consumption will hinder the scalability issues of Bitcoin, however the other issue that arises with POW mining is that with the increase in cost associated with mining BTC it is less economical to mine Bitcoin. This would limit the distributed nodes (miners) globally and allow a larger percentage of control to the dominant mining pools / farms.
This would lead to a more centralized blockchain, where they can change the rules of BTC as they please.
The supply of Bitcoin is finite, capped at 21 million. Eventually (currently predicted for 2140) Bitcoin's supply will run out. Once this happens, miners will no longer receive rewards for completing blocks but instead will be given fees. The fees will be drastically high in relative terms, and people will stop using the blockchain.
Also, if miners decide that this is uneconomical for them to process the transactions and use their computing power elsewhere the speed of transactions for Bitcoin will drastically slow down, rendering one of the fundamental values of a Bitcoin (speed) useless.
Blue chip Companies
This is more so for all cryptocurrencies, but Bitcoin in particular. It’s not a matter of if but a matter of when a blue-chip company such as Facebook, Amazon or Google decides to implement their own cryptocurrency.
Another possibility is a potential ‘world coin’ which global governments will all agree on using, this may seem unrealistic but it is definitely not impossible and many benefits would arise from having such a currency.
Quantum Computing
Bitcoin is said to be Quantum resistant, on the whitepaper it mentions that:
‘To compensate for increasing hardware speed and varying interest in running nodes over time, the proof-of-work difficulty is determined by a moving average targeting an average number of blocks per hour. If they're generated too fast, the difficulty increases.’
This may seem quantum resistant but it is important to understand that the difficulty is changed every 10 minutes and this is more than enough time for QC to mine all of Bitcoin’s remaining coins.
Bitcoin Bubble
The last point of this section is to recognize that the Bitcoin bubble could pop loud enough to crash the market. Due to a whole lot of hype, and even more speculative and uneducated buyers, Bitcoin could face a peak in which a simple spark
Ethereum
What is Ethereum?
Ethereum is an open source platform with the mission to build and inspire next-generation decentralized applications. In other words, the applications being built on the Ethereum network would have no middle men. Users are able to interact safely with social and financial systems to transact peer to peer, therefore opening a new realm of opportunity within decentralized development on specifically the exchange of value.
Like the Bitcoin network exchanges Bitcoin, applications within the Ethereum network would exchange ETHER. Therefore, making the Ethereum network have its own digital currency or, cryptocurrency that these decentralized applications would run on.
On the Ethereum network, developers are able to build these decentralized applications simply, within this seemingly complicated new technology. Think of it as Shopify or Volusion, these are centralized networks in which users/developers can build e-commerce stores more efficiently and cost effectively.
Ethereum is similar in this aspect, the network was essentially created to assist and fuel the growth of decentralized blockchain applications within its network.
Smart Contracts
Now, what Ethereum is based on, is a thing called “Smart Contracts”
Developers are extremely excited about this tool, a smart contract is similar to how it sounds, it’s a digital contract that self-executes… Think of it as a virtual vending machine.
A smart contract is a digital contract between two people in which the technology or tool handles the management, performance, enforcement and payment of the agreement. The smart contract has its own digital bank account of ETHER and settles once the product is received or the service is completed therefore greatly improving the efficiency of data tracking, payment processing and user friendliness of each decentralized application.
Let’s dive into an example
Music
The first age of the internet brought quite a bit of disruption to the music industry… Idk if you knew, but if you we’re a songwriter 25 years ago and produced a hit song that got a million singles you would acquire royalties of up to $50,000. Now if you were to produce a hit song that gets a million streams you don’t get $50,000, you get $45… Enough to cover the first round at the bar.
In result, musicians are now finding other ways to produce revenue with their music. One being the utilization of a blockchain ecosystem like Ethereum. Music applications are now being built for musicians to reclaim their content, smart contracts are being implemented into the music itself, therefore the music protects the intellectual property rights of the artist.
You want to listen to the song? It’s free… or maybe a few micro pennies to download. You want to put the song in your video or movie? Make it your ringtone? These each cost a different price and presented at the point of purchase would be its underlying IP rights for the use of that piece of music.
Musicians are absolutely hyped about this because now, the song becomes a business. It’s out there on this platform marketing itself, protecting the rights of the author and because the song has a payment system; in the sense of a bank account, all of the money then flows back to the artist, and they control the industry rather than these powerful intermediaries.
This concept could apply not only to just songwriters but any creator of content, from art, to inventions, to scientific discoveries or the work from independent journalists. There are endless industries in which people do not gain fair compensation in which the underlying technology of Ethereum could benefit in a big way.
Other examples:
· A smart contract can be created to pay a worker for every hour they work, they log their hours on the blockchain and then after verification the funds are instantly transferred to them
· Buying goods internationally can be tracked and verified – reducing fraud.
· Property buying can be facilitated through the contract
· Every industry that has a contract in place will be able to use the blockchain of Ethereum
It is also worth noting that Ethereum is also a lot quicker than Bitcoin, average block time being 15 seconds for Ethereum opposed to 10 minutes for Bitcoin.
Personally, I am invested into both. If I HAD to choose, like I said it would be Ethereum simply because of where it is now in comparison to its potential as well as its very transparent, direct, opportunistic mission towards the hosting of decentralized blockchain applications.

[META] New to PC Building? - September 2018 Edition

Intro

You've heard from all your gaming friends/family or co-workers that custom PCs are the way to go. Or maybe you've been fed up with your HP, Dell, Acer, Gateway, Lenovo, etc. pre-builts or Macs and want some more quality and value in your next PC purchase. Or maybe you haven't built a PC in a long time and want to get back into the game. Well, here's a good place to start.

Instructions

  1. Make a budget for your PC (e.g., $800, $1000, $1250, $1500, etc.).
  2. Decide what you will use your PC for.
    • For gaming, decide what games and at what resolution and FPS you want to play at.
    • For productivity, decide what software you'll need and find the recommended specs to use those apps.
    • For a bit of both, your PC build should be built on the HIGHEST specs recommended for your applications (e.g., if you only play FortNite and need CPU power for CFD simulations, use specs recommended for CFD).
    Here are some rough estimates for builds with entirely NEW parts:
    1080p 60FPS ultra-settings modern AAA gaming: ~$1,200
    1440p 60FPS high/ultra-settings modern AAA gaming: ~$1,600
    1080p 144FPS ultra-settings modern AAA gaming: $2,000
    4K 50FPS medium/high-settings modern AAA gaming: > $2,400
    It's noted that some compromises (e.g., lower settings and/or resolution) can be made to achieve the same or slightly lower gaming experience within ±15% of the above prices. It's also noted that you can still get higher FPS on older or used PCs by lowering settings and/or resolution AND/OR buying new/used parts to upgrade your system. Make a new topic about it if you're interested.
    Also note that AAA gaming is different from e-sport games like CSGO, DOTA2, FortNite, HOTS, LoL, Overwatch, R6S, etc. Those games have lower requirements and can make do with smaller budgets.
  3. Revise your budget AND/OR resolution and FPS until both are compatible. Compare this to the recommended requirements of the most demanding game on your list. For older games, you might be able to lower your budget. For others, you might have to increase your budget.
    It helps to watch gaming benchmarks on Youtube. A good example of what you're looking for is something like this (https://www.youtube.com/watch?v=9eLxSOoSdjY). Take note of the resolution, settings, FPS, and the specs in the video title/description; ask yourself if the better gaming experience is worth increasing your budget OR if you're okay with lower settings and lowering your budget. Note that you won't be able to see FPS higher than 60FPS for Youtube videos; something like this would have to be seen in-person at a computer shop.
  4. Make a build on https://ca.pcpartpicker.com/. If you still have no idea how to put together parts, start here (http://www.logicalincrements.com/) to get an understanding of PC part tiers. If you want more info about part explanations and brief buying tips, see the next section below.
  5. Click on the Reddit logo button next to Markup, copy and paste the generated text (in markup mode if using new Reddit), and share your build for review!
  6. Consider which retailer to buy your parts from. Here's a table comparing different retailers: https://docs.google.com/spreadsheets/d/1L8uijxuoJH4mjKCjwkJbCrKprCiU8CtM15mvOXxzV1s/edit?usp=sharing
  7. Buy your parts! Use PCPP above to send you e-mail alerts on price drops or subscribe to /bapcsalescanada for deals.
    You can get parts from the following PC retailers in alphabetical order:
  8. After procuring your parts, it's time to build. Use a good Youtube tutorial like this (https://www.youtube.com/watch?v=IhX0fOUYd8Q) that teach BAPC fundamentals, but always refer to your product manuals or other Youtube tutorials for part-specific instructions like CPU mounting, radiator mounting, CMOS resetting, etc. If it everything still seems overwhelming, you can always pay a computer shop or a friend/family member to build it for you.
    It might also be smart to look up some first-time building mistakes to avoid:
  9. Share your experience with us.
  10. If you have any other questions, use the search bar first. If it's not there, make a topic.

BAPC News (Last Updated - 2018/09/20)

CPU

https://www.tomshardware.com/news/intel-9000-series-cpu-faq,37743.html
Intel 9000 CPUs (Coffee Lake Refresh) will be coming out in Q4. With the exception of i9 (8-core, 12 threads) flagship CPUs, the i3, i5, and i7 lineups are almost identical to their Intel 8000 (Coffee Lake) series, but slightly clocked faster. If you are wondering if you should upgrade to the newer CPU on the same tier (e.g., i5-8400 to i5-9400), I don't recommend that you do as you will only see marginal performance increases.

Mobo

https://www.anandtech.com/show/13135/more-details-on-intels-z390-chipset-exposed
Z370s will now be phased out for Z390s boards, which will natively support Intel 9000 CPUs (preferably i5-9600K, i7-9700K, and i9-9900K).

GPU

https://www.youtube.com/watch?v=WDrpsv0QIR0
RTX 2080 and 2080 Ti benchmarks are out; they provide ~10 and ~20 frames better than the 1080 Ti and also feature ray tracing (superior lighting and shadow effects) which is featured in only ~30 games so far (i.e., not supported a lot); effectively, they provide +25% more performance for +70% increased cost. My recommendation is NOT to buy them unless you need it for work or have lots of disposable income. GTX 1000 Pascal series are still relevant in today's gaming specs.

Part Explanations

CPU

The calculator part. More GHz is analogous to fast fingers number crunching in the calculator. More cores is analogous to having more calculators. More threads is analogous to having more filing clerks piling more work for the calculator to do. Microarchitectures (core design) is analogous to how the internal circuit inside the calculator is designed (e.g., AMD FX series are slower than Intel equivalents even with higher OC'd GHz speeds because the core design is subpar). All three are important in determining CPU speed.
In general, higher GHz is more important for gaming now whereas # cores and threads are more important for multitasking like streaming, video editing, and advanced scientific/engineering computations. Core designs from both AMD and Intel in their most recent products are very good now, but something to keep in mind.

Overclocking

The basic concept of overclocking (OCing) is to feed your CPU more power through voltage and hoping it does calculations faster. Whether your parts are good overclockers depends on the manufacturing process of your specific part and slight variations in materials and manufacturing process will result in different overclocking capability ("silicon lottery"). The downside to this is that you can void your warranties because doing this will produce excess heat that will decrease the lifespan of your parts AND that there is a trial-and-error process to finding OC settings that are stable. Unstable OC settings result in computer freezes or random shut-offs from excess heat. OCing will give you extra performance often for free or by investing in a CPU cooler to control your temperatures so that the excess heat will not decrease your parts' lifespans as much. If you don't know how to OC, don't do it.

Current Products

Intel CPUs have higher GHz than AMD CPUs, which make them better for gaming purposes. However, AMD Ryzen CPUs have more cores and threads than their Intel equivalents. The new parts are AMD Ryzen 3, 5, or 7 2000 series or Intel i3, i5, or i7 8000 series (Coffee Lake). Everything else is outdated.
If you want to overclock on an AMD system, know that you can get some moderate OC on a B350/B450 with all CPUs. X370/X470 mobos usually come with better VRMs meant for OCing 2600X, 2700, and 2700X. If you don't know how to OC, know that the -X AMD CPUs have the ability to OC themselves automatically without manually settings. For Intel systems, you cannot OC unless the CPU is an unlocked -K chip (e.g., i3-8350K, i5-8600K, i7-8700K, etc.) AND the motherboard is a Z370 mobo. In general, it is not worth getting a Z370 mobo UNLESS you are getting an i5-8600K and i7-8700K.

CPU and Mobo Compatibility

Note about Ryzen 2000 CPUs on B350 mobos: yes, you CAN pair them up since they use the same socket. You might get an error message on PCPP that says that they might not be compatible. Call the retailer and ask if the mobo you're planning on buying has a "Ryzen 2000 Series Ready" sticker on the box. This SHOULD NOT be a problem with any mobos manufactured after February 2018.
Note about Intel 9000 CPUs on B360 / Z370 mobos: same as above with Ryzen 2000 CPUs on B350 or X370 boards.

CPU Cooler (Air / Liquid)

Air or liquid cooling for your CPU. This is mostly optional unless heavy OCing on AMD Ryzen CPUs and/or on Intel -K and i7-8700 CPUs.
For more information about air and liquid cooling comparisons, see here:

Motherboard/mobo

Part that lets all the parts talk to each other. Comes in different sizes from small to big: mITX, mATX, ATX, and eATX. For most people, mATX is cost-effective and does the job perfectly. If you need more features like extra USB slots, go for an ATX. mITX is for those who want a really small form factor and are willing to pay a premium for it. eATX mobos are like ATX mobos except that they have more features and are bigger - meant for super PC enthusiasts who need the features.
If you are NOT OCing, pick whatever is cheap and meets your specs. I recommend ASUS or MSI because they have RMA centres in Canada in case it breaks whereas other parts are outside of Canada like in the US. If you are OCing, then you need to look at the quality of the VRMs because those will greatly influence the stability and lifespan of your parts.

Memory/RAM

Part that keeps Windows and your software active. Currently runs on the DDR4 platform for new builds. Go for dual channel whenever possible. Here's a breakdown of how much RAM you need:
AMD Ryzen CPUs get extra FPS for faster RAM speeds (ideally 3200MHz) in gaming when paired with powerful video cards like the GTX 1070. Intel Coffee Lake CPUs use up a max of 2667MHz for B360 mobos. Higher end Z370 mobos can support 4000 - 4333MHz RAM depending on the mobo, so make sure you shop carefully!
It's noted that RAM prices are highly inflated because of the smartphone industry and possibly artificial supply shortages. For more information: https://www.extremetech.com/computing/263031-ram-prices-roof-stuck-way

Storage

Part that store your files in the form of SSDs and HDDs.

Solid State Drives (SSDs)

SSDs are incredibly quick, but are expensive per TB; they are good for booting up Windows and for reducing loading times for gaming. For an old OEM pre-built, upgrading the PC with an SSD is the single greatest speed booster you can do to your system. For most people, you want to make sure the SSD you get is NOT DRAM-less as these SSDs do not last as long as their DRAM counterparts (https://www.youtube.com/watch?v=ybIXsrLCgdM). It is also noted that the bigger the capacity of the SSD, the faster they are. SSDs come in four forms:
The 2.5" SATA form is cheaper, but it is the old format with speeds up to 550MB/s. M.2 SATA SSDs have the same transfer speeds as 2.5" SATA SSDs since they use the SATA interface, but connect directly to the mobo without a cable. It's better for cable management to get an M.2 SATA SSD over a 2.5" SATA III SSD. M.2 PCI-e SSDs are the newest SSD format and transfer up to 4GB/s depending on the PCI-e lanes they use (e.g., 1x, 2x, 4x, etc.). They're great for moving large files (e.g., 4K video production). For more info about U.2 drives, see this post (https://www.reddit.com/bapccanada/comments/8jxfqs/meta_new_to_pc_building_may_2018_edition/dzqj5ks/). Currently more common for enterprise builds, but could see some usage in consumer builds.

Hard Disk Drives (HDDs)

HDDs are slow with transfer speeds of ~100MB/s, but are cheap per TB compared to SSDs. We are now at SATA III speeds, which have a max theoretical transfer rate of 600MB/s. They also come in 5400RPM and 7200RPM forms. 5400RPM uses slightly less power and are cheaper, but aren't as fast at dealing with a large number of small files as 7200RPM HDDs. When dealing with a small number of large files, they have roughly equivalent performance. It is noted that even a 10,000RPM HDD will still be slower than an average 2.5" SATA III SSD.

Others

SSHDs are hybrids of SSDs and HDDs. Although they seem like a good combination, it's much better in all cases to get a dedicated SSD and a dedicated HDD instead. This is because the $/speed better for SSDs and the $/TB is better for HDDs. The same can be said for Intel Optane. They both have their uses, but for most users, aren't worth it.

Overall

I recommend a 2.5" or M.2 SATA ≥ 250GB DRAM SSD and a 1TB or 2TB 7200RPM HDD configuration for most users for a balance of speed and storage capacity.

Video Card/GPU

Part that runs complex calculations in games and outputs to your monitor and is usually the most expensive part of the budget. The GPU you pick is dictated by the gaming resolution and FPS you want to play at.
In general, all video cards of the same product name have almost the same non-OC'd performance (e.g., Asus Dual-GTX1060-06G has the same performance as the EVGA 06G-P4-6163-KR SC GAMING). The different sizes and # fans DO affect GPU OCing capability, however. The most important thing here is to get an open-air video card, NOT a blower video card (https://www.youtube.com/watch?v=0domMRFG1Rw). The blower card is meant for upgrading pre-builts where case airflow is limited.
For cost-performance, go for the NVIDIA GTX cards because of the cryptomining industry that has inflated AMD RX cards. Bitcoin has taken a -20% hit since January's $10,000+ as of recently, but the cryptomining industry is still ongoing. Luckily, this means prices have nearly corrected itself to original MSRP in 2016.
In general:
Note that if your monitor has FreeSync technology, get an AMD card. If your monitor has G-Sync, get a NVIDIA card. Both technologies allow for smooth FPS gameplay. If you don't have either, it doesn't really matter which brand you get.
For AMD RX cards, visit https://www.pcworld.com/article/3197885/components-graphics/every-amd-radeon-rx-graphics-card-you-can-buy-for-pc-gaming.html

New NVIDIA GeForce RTX Series

New NVIDIA 2000 RTX series have been recently announced and will be carried in stores in Q3 and Q4. Until all of the products have been fully vetted and reviewed, we cannot recommend those yet as I cannot say if they are worth what NVIDIA has marketed them as. But they will be faster than their previous equivalents and will require more wattage to use. The 2070, 2080, and 2080 Ti will feature ray tracing, which is a new feature seen in modern CG movies that greatly enhances lighting and shadow effects. At this time, < 30 games will use ray tracing (https://www.pcgamer.com/21-games-will-support-nvidias-real-time-ray-tracing-here-are-demos-of-tomb-raider-and-control/). It's also noted that the 2080 Ti is the Titan XP equivalent, which is why it's so expensive. (https://www.youtube.com/watch?v=Irs8jyEmmPQ) The community's general recommendation is NOT to pre-order them until we see some reviews and benchmarks from reviewers first.
Looks like a couple of benchmarks are out. While keeping other parts equal the following results were obtained(https://videocardz.com/77983/nvidia-geforce-rtx-2080-ti-and-rtx-2080-official-performance-unveiled). So the 2080 and 2080 Ti are better than last generation's 1080 Ti by ~10 and ~20 frames respectively.

Case

Part that houses your parts and protects them from its environment. Should often be the last part you choose because the selection is big enough to be compatible with any build you choose as long as the case is equal to or bigger than the mobo form factor.
Things to consider: aesthetics, case airflow, cable management, material, cooling options (radiators or # of fan spaces), # fans included, # drive bays, toolless installation, power supply shroud, GPU clearance length, window if applicable (e.g., acrylic, tempered glass), etc.
It is recommended to watch or read case reviews on Youtube to get an idea of a case's performance in your setup.

Power Supply/PSU

Part that runs your PC from the wall socket. Never go with an non-reputable/cheap brand out on these parts as low-quality parts could damage your other parts. Recommended branded PSUs are Corsair, EVGA, Seasonic, and Thermaltake, generally. For a tier list, see here (https://linustechtips.com/main/topic/631048-psu-tier-list-updated/).

Wattage

Wattage depends on the video card chosen, if you plan to OC, and/or if you plan to upgrade to a more powerful PSU in the future. Here's a rule of thumb for non-OC wattages that meet NVIDIA's recommendations:
There are also PSU wattage calculators that you can use to estimate your wattage. How much wattage you used is based on your PC parts, how much OCing you're doing, your peripherals (e.g., gaming mouse and keyboard), and how long you plan to leave your computer running, etc. It is noted that these calculators use conservative estimates, so use the outputted wattage as a baseline of how much you need. Here are the calculators (thanks, VitaminDeity).
Pick ONE calculator to use and use the recommended wattage, NOT recommended product, as a baseline of what wattage you need for your build. Note that Cooler Master and Seasonic use the exact calculator as Outervision. For more details about wattage, here are some reference videos:

Modularity

You might also see some info about modularity (non-modular, semi-modular, or fully-modular). These describe if the cables will come connected to the PSU or can be separated of your own choosing. Non-modular PSUs have ALL of the cable connections attached to the PSU with no option to remove unneeded cables. Semi-modular PSUs have separate cables for HDDs/SSDs and PCI-e connectors, but will have CPU and mobo cables attached. Modular PSUs have all of their cables separate from each other, allowing you to fully control over cable management. It is noted that with decent cooling and airflow in your case, cable management has little effect on your temperatures (https://www.youtube.com/watch?v=YDCMMf-_ASE).

80+ Efficiency Ratings

As for ratings (80+, 80+ bronze, 80+ gold, 80+ platinum), these are the efficiencies of your PSU. Please see here for more information. If you look purely on electricity costs, the 80+ gold PSUs will be more expensive than 80+ bronze PSUs for the average Canadian user until a breakeven point of 6 years (assuming 8 hours/day usage), but often the better performance, longer warranty periods, durable build quality, and extra features like fanless cooling is worth the extra premium. In general, the rule of thumb is 80+ bronze for entry-level office PCs and 80+ gold for mid-tier or higher gaming/workstation builds. If the price difference between a 80+ bronze PSU and 80+ gold PSU is < 20%, get the 80+ gold PSU!

Warranties

Warranties should also be looked at when shopping for PSUs. In general, longer warranties also have better PSU build quality. In general, for 80+ bronze and gold PSU units from reputable brands:
Any discrepancies are based on varied wattages (i.e., higher wattages have longer warranties) or updated warranty periods. Please refer to the specific product's warranty page for the correct information. For EVGA PSUs, see here (https://www.evga.com/support/warranty/power-supplies/). For Seasonic PSUs, see here (https://seasonic.com/support#period). For Corsair PSUs, see here (https://www.corsair.com/ca/en/warranty).
For all other PSU inquiries, look up the following review sites for the PSUs you're interested in buying:
These guys are engineering experts who take apart PSUs, analyze the quality of each product, and provide an evaluation of the product. Another great website is http://www.orionpsudb.com/, which shows which PSUs are manufactured by different OEMs.

Operating System (OS)

Windows 10

The most common OS. You can download the ISO here (https://www.microsoft.com/en-ca/software-download/windows10). For instructions on how to install the ISO from a USB drive, see here (https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/install-windows-from-a-usb-flash-drive) or watch a video here (https://www.youtube.com/watch?v=gLfnuE1unS8). For most users, go with the 64-bit version.
If you purchase a Windows 10 retail key (i.e., you buy it from a retailer or from Microsoft directly), keep in mind that you are able to transfer it between builds. So if you're building another PC for the 2nd, 3rd, etc. time, you can reuse the key for those builds PROVIDED that you deactivate your key before installing it on your new PC. These keys are ~$120.
However, if you have an OEM key (e.g., pre-builts), that key is tied specifically to your mobo. If you ever decide to upgrade your mobo on that pre-built PC, you might have to buy a new Windows 10 license. For more information, see this post (https://www.techadvisor.co.uk/feature/windows/windows-10-oem-or-retail-3665849/). The cheaper Windows 10 keys you can find on Kinguin are OEM keys; activating and deactivating these keys may require phoning an automated Microsoft activation line. Most of these keys are legitimate and cost ~$35, although Microsoft does not intend for home users to obtain this version of it. Buyer beware.
The last type of key is a volume licensing key. They are licensed in large volumes to corporate or commercial usage. You can find lots of these keys on eBay for ~$10, but if the IT department who manages these keys audit who is using these keys or if the number of activations have exceeded the number allotted on that one key, Microsoft could block that key and invalidate your license. Buyer beware.
For more information on differentiating between all three types of keys, see this page (https://www.tenforums.com/tutorials/49586-determine-if-windows-license-type-oem-retail-volume.html).
If money is tight, you can get Windows 10 from Microsoft and use a trial version of it indefinitely. However, there will be a watermark in the bottom-right of your screen until you activate your Windows key.

MacOS

If you're interested in using MacOS, look into Hackintosh builds. This will allow you to run MacOS to run on PC parts, saving you lots of money. These builds are pretty picky about part compatibility, so you might run into some headaches trying to go through with this. For more information, see the following links:

Linux

If you're interested in a free open-source OS, see the following links:
For more information, go to /linux, /linuxquestions, and /linux4noobs.

Peripherals

Monitors

Keyboards and Mice

Overall

Please note that the cost-performance builds will change daily because PC part prices change often! Some builds will have excellent cost-performance one day and then have terrible cost-performance the next. If you want to optimize cost-performance, it is your responsibility to do this if you go down this route!
Also, DO NOT PM me with PC build requests! It is in your best interests to make your own topic so you can get multiple suggestions and input from the community rather than just my own. Thanks again.

Sample Builds

Here are some sample builds that are reliable, but may not be cost-optimized builds. These builds were created on September 9, 2018; feel free to "edit this part list" and create your own builds.

Sorry for the lack of updates. I recently got a new job where I work 12 hours/day for 7 days at a time out of the city. What little spare time I have is spent on grad school and the gym instead of gaming. So I've been pretty behind on the news and some might not be up-to-date as my standards would have been with less commitments. If I've made any mistakes, please understand it might take a while for me to correct them. Thank you!

Qtum Co Founder Patrick Dai | "3 o'clock no sleep blockchain" depth of sharing

In the industry known as the "first block of the block community," the three o'clock sleepless block chain group, brought together the heavyweight figures in the domestic block chain industry. On the second day of the New Year, starting at 11 am, the group members with a total market capitalization of about 1 trillion yuan, as the traditional world still rejoice in the Great Reign, Technology, valuation, investment and future, the main questions raised in the group were carefully answered and shared. The full text is as follows:
 
Q1: Stellar recently fierce in Silicon Valley, do you think the threat to eth big?
Patrick Dai: ETH has become an ecosystem where the greatest risk comes from the risks inherent in one's own ecology but less from outside risks unless there is a tenfold increase in Ethereum's advanced ideas and technologies, giving it an opportunity to replace Ethereum , Otherwise it is a big threat to the nature, but not competing with the front of Ethereum, in other areas (outside the ICO) force, there are still a lot of business and investment opportunities.
 
Q2: What do you think about the millions of TPS that eos claims?
Patrick Dai: Blockchain is not born for the TPS, if we need faster TPS, the existing banking system and Paypal and WeChat payment, is a better choice. In addition to the degree of decentralization and TPS is basically an irreconcilable conflict, many of the replacement of TPS is to sacrifice network to the degree of centralization to obtain, I personally think, simply in pursuit of higher TPS, but it makes no sense , Especially if the network after only a few dozen large nodes (this is not the early stages of the bank?), Then the high TPS, very often not significant.
 
TPS makes sense for specific things, but requires a compromise with the philosophy behind cryptocurrencies. Because traditional IT technology has been studied for distributed systems for decades, all algorithms based on BFT and various variants can achieve very high TPS, but their degree of centralization is relatively high. The average person in the network is Can not get the right of reciprocity If you can not participate in the supervision and verification of the network, in fact, the use of existing financial services are more than enough.
 
Question 3: Qtum Chain initial design of the core of what is the point? Qtum how to build their own ecology? Qtum globalization is good, even South Koreans like Qtum,landing strategies and methods in different states around the world how to look?**
 
Patrick Dai:
The core of Qtum Blockchain design:
  1. Security, security is the number one priority for cryptocurrency systems, with no foundation for security and sophisticated software as a back-up.
  2. Qtum chain is basically compatible with bitcoin's UTXO and all BIPs, and is also compatible with EVM and EVM-based ecology.
  3. Flexible, the biggest innovation in Qtum is based on bitcoin transaction model, which supports the implementation of smart contract, so that Ethereum's virtual machine can run on the bitcoin network. In addition, the current Qtum network is already in the POS phase, and around 3000 A full node. POS is more friendly to business applications. Through technical support, development tools, Community Roadshow investment hatching in the constant construction of the ecology of the Qtum Blockchain. The more important thing is landing on the local community developers and local project developers to achieve localization, the international team will also be a lot of help.
 
Question 4: Decentralized trading system, the future direction of development is?
 
Patrick Dai: to the center of the trading system of my research is not much to talk about a few specific cases, the earliest to the center of the trading system is based on the colorcoin mastercoin and counterparty transactions colorcoin on the back appeared on NXT and the BTS Decentralized trading systems, followed by the emergence of etherdelta (based on the smart contract trading system), from the experience above, several decentralized trading system experience, similar to the centralized trading system of high-frequency mobile Sex, a great gap. About decentralized trading system in the order matching and order synchronization, this can find some developers in this area, consult.
 
Q5: ipfs really can really decentralized web and app? Not a simple one? What is the point of going to a centralized app?
Patrick Dai: IPFS specific technology to achieve no in-depth study, but read the design concept, the project itself also mentioned for several years, to the center of the web and app should be serverless service to developers, as long as the interface , Regardless of who behind the service to provide. Is not a simple token, depending on the ecology behind it, bitcoin is essentially just a piece of data in a bitcoin network, and decentralized apps make sense, but at the moment many of Dapp's really just an app + blockchain as a settlement layer .
However, the future of blockchain and Dapp's future will transcend the existence of cryptocurrency and will become a social infrastructure: trust. Dapp has a lot of good direction: the game (props channels), content (movie music text), Internet of things, ID and so on.
 
Q6: Everyone has been saying that it is necessary to decentralize and intensify the high level of Dapp's certain degree of contradictions. However, we can not just stay at the stage where btc is used as a currency and eth only serves as a currency to be raised. Developing Dapps to address user needs, that is, the need to strike a balance between a purely decentralized utopia and user application world, Dpos is a solution for now, what do you think? How to grasp the degree of the two?
Patrick Dai: Indeed, many Dapp is a pseudo-concept, but cryptocurrency itself has begun to penetrate into various places as the first successful application based on blockchain technology. My consideration for the future blockchain system is that there is enough decentralization at the bottom and the application layer can be neutralized. We need a trustless bottom plus an application layer that requires trust, on the one hand, a trustless premium (trust cost Lowest) + centralized premium (centralized), Dapp still has a lot to see in the future, such as gaming (virtual assets and channel changes) digital content (movie music) Internet of Things security and management of digital identities Areas of Pratt & Whitney Finance (Insurance-autonomous finance and micro-financial services, etc.).
At present, many Dapp just use the characteristics of a blockchain, that is, the issuance and clearing of tokens. The blockchain has many other features that need to be discovered and discovered.
 
Q7: How do you think about the feasibility and security of cross-link technology? At present, you are optimistic about this project. In addition, how to ensure the trust and reliability of the link in the chain?
Patrick Dai: I personally feel that the current cross-link area is still in its early stages, both in bitcoin and Ethereum network have limited processing power, and the process of continuous evolution, I personally feel that this one cross-chain is not yet mature enough, and from the solution Just need to point out whether cross-link at least at this stage is not just a need.
On the Oracle side, this is a need, especially in the popularization of smart contracts, we need the blockchain can access external systems, in a sense, the current blockchain is an algorithm-driven self-consistent Closed system, the logic is pre-set. Through Oracle we can introduce external data sources to trigger the execution of the contract. There are many directions on how to solve the problem of credible data sources.
One is a centralized approach, such as providing data sources by auditing companies and government departments. Another way to go to the center is to introduce games and mortgages. Punish fraud and reward honest data sources and establish a preferred positive feedback mechanism. Of course, there are many other solutions, there is a lot of community research, Microsoft also has a cryptolet project.
 
Q8: Ask a funny, 10 times eth, I have been curious about this issue, high-dimensional playing low-dimensional, non-dimensional entanglement. You must have thought about this 10 times the problem or possible direction method, want to hear you talk about the possibility of 10 times the direction of eth?
Patrick Dai: 10 times ETH advanced concepts and technology iteration, ETH basically invest this thing is done through the ICO done the ultimate, 15 seconds to complete the investment process (DD TS Token release). It takes a few months, compared to the traditional melting of an angel, which is a difference of 15 seconds vs 3 months. So somehow, ETH becomes the largest investment and financing platform in the world. This is also the largest application of Ethereum, but the application of other smart contracts but did not develop.
 
From the cash point of view there are several directions:
  1. distributed governance (refer to bitcoin 1M to 2M process and DAO processing);
  2. system of self-evolution and evolution;
  3. ease of use 10 times the increase;
 
From a technical point of view:
  1. scalability (full node size participation threshold TPS reciprocal rights);
  2. privacy and application independence and loose coupling (refer to Parity theft);
  3. Better flexibility (more types of virtual machines and a wider range of smart contract languages);
  4. network layering and partitioning and data compression;
  5. new consensus mechanisms (often requiring years of testing and practice) and more.
 
Q9: On the current blockchain + distributed computing issues, I think in the future if the dapp market can really make it indispensable based on the blockchain program to solve the calculation, storage, node acceleration and other issues. Currently I see several projects on distributed computing are based on the construction of Ethereum, are worrying about the performance, how do you think?
Patrick Dai: Distributed Computing I did not study much, but its initial project should come from MaidSafe (https://maidsafe.net/), a nearly 10-year project, essentially Proof of Resource, and many others. The type of computation is actually not very suitable for distributed processing, requiring serial processing of data that is essentially not accelerated through distributed computing, and distributed computing may be able to handle similar game rendering and image rendering needs, but I do not know How big is a market?
In addition, in distributed computing, it is also a problem how to use a common programming language to describe the computing task to be calculated and submit it accurately to the computing node. This one can consult the head of distributed computing projects.
 
Q10: Analysis of the following characteristics and advantages and disadvantages of the underlying chain: BTC / QTUM / ETH / EOS / NEO / ELASTOS?
 
Q11: At present more discussion is the public chain and the basic agreement, the application of technology in the future how to develop, what application scenarios faster landing?
Patrick Dai: The current blockchain technology is still in its early stages of evolution, standing in the Internet era 20 years ago, when we can hardly imagine today can be called a mobile phone uber, the development of technology to give everyone a more rich diversity The possibility is the future.
From an application perspective, the blockchain industry is indeed in the early stages of its application. Cryptocurrency is relative to the blockchain, similar to Email versus Internet, but the development behind the Internet goes far beyond emailing for information exchange, Then the future development of the blockchain will certainly not stop at cryptocurrencies born for value exchange.
Cryptocurrency is just the beginning. From a scenario perspective, the biggest feature of blockchain technology is that it guarantees a trustless platform through a variety of technologies, a trust-free platform that reduces the cost of all business transactions.
 
Q12: First ask yourself a few questions: blockchain where the biggest investment opportunities?
Patrick Dai: Based on the changes and disruptiveness brought by cryptocurrency, its wealth is created faster than the industrial revolution and the information revolution. From an investment point of view, I personally feel that there are several good directions:
  1. Encrypted currency (cryptocurrency and token) in the underlying publicchain, which basically became the industry's first token-based blockchain technology with a close combination of blockchain
  2. Technologies and specific application scenarios (the industry is in its infancy)
  3. Encryption Asset Services Portal (Wallet Exchange IM)
  4. Breaking Down Scenarios Across Industries (Games, Entertainment, IoT, ID, Healthcare, Supply Chain)
  5. Organizational Change Research, Economics, Think Tanks, Deep Media.
 
Q13: Is cryptocurrency popular at large scale?
Patrick Dai: the development of technology with jumping, but difficult to retract, with the car, the car will never disappear, although the carriage also continued to exist for hundreds of years. The advent of cryptocurrency is not a coincidence, but is accompanied by the maturity of various internet infrastructures and the enlightenment of Cyber ​​punk movement concept. It belongs to the fusion of technology and thought, not just to technological innovation.
Personally, I think the cryptocurrency is unlikely to disappear, the widespread adoption of cryptocurrency depends on the applicability of the cryptocurrency system, including what rigid demands are being addressed, and for the moment, the greatest use is to provide people around the world an option: a very fluid Transparent, credible, secure global assets.
 
Q14: How to build a valuation model of blockchain platform?
Patrick Dai: I have sent an article before. At present, this is a big problem in the industry. We do not have a set of valuation system to realize early warning and assessment of risks. What is the valuation of a project? Before writing something for your reference. http://www.gongxiangcj.com/posts/3895 "The number of nodes and cryptocurrency valuation model."
 
Q15: Who is Nakamoto?
Patrick Dai: From what I learned, Nakamoto was a hardworking man with idealistic feelings. It should be done independently by one person. There are many anonymous tech bucks in IRC channel in 2011 and 2012, on which you can see Nakamoto's figure. In addition to the birth of BTC, there is also some relationship with a Chinese Wei Dai.
Wei Dai, who wrote Bmoney's paper before, Zhong Zhongcong and Wei Dai also had some emails, and mentioned to Wei Dai that he has implemented Bmoney's part of cryptoCurrency, but in the second part of Bmoney there is actually a tentative idea about the contract. We can refer to Wei Dai's thesis at http://www.weidai.com/bmoney.txt and Qtum's idea Wei Dai has had some simple email exchanges, but Wei Dai's interest is no longer in the circle of cryptocurrencies.
 
Q16: In all the coins, which one will live the longest?
Patrick Dai: simply look at cryptocurrencies, BTC completed a historic jump, but also a breakthrough from 0 to 1, followed by many cryptocurrencies are 1 to 1.1 and 1.1 to 1.2 changes, more than one billion US dollars in the amount of encrypted currency thoroughly It is unlikely that it will disappear because of the drive and governance of the community that the community will uphold even if the developer does not maintain it. However, there are indeed many crypto-currencies that will be eliminated and 95% of the projects should be gone after three years.
 
Q17: 18 years blockchain private market analysis, what kind of industry is better?
Patrick Dai: Currently the industry needs to find other applications in addition to the cryptocurrency killer app, from the technical development point of view, I personally trust the concept of trustless Platform constantly landing and provide the underlying technology research and development and application scenarios.
 
Q18: Which industry has the largest total of all the industries in the blockchain?
Patrick Dai: Cryptocurrency itself seems to be the biggest at this moment, and others feel that there are many opportunities for the gaming industry and for digital content (video and audio) and for financial services and the Internet of Things.
 
Q19: Want to hear the competition between the public chain and the public relations and cooperation, how to comment on the big brother?
Patrick Dai: last year's growth in the industry, in essence, we are still eating BTC created by the combination of technology and ideas, creating a human species in the history of a new species premium, BTC has its historic significance. The groundbreaking idea it brought, gradually attracted the public's attention, but from a technical point of view, what BTC can do is limited, but it does solve its positioning.
Technology is not good or bad, mainly to meet the needs. BTC technology to meet its point-to-point electronic cash system positioning and needs. We do not expect to build infinite applications in the BTC above, this is impossible. The public chain is indeed an open experimental field and a community-driven evolutionary community of interests. Its vitality is also very strong. However, at present, the problem is that we really need technological progress to further promote the scene. If only from the perspective of cryptocurrency, BTC LTC DogeCoin for a user, in essence, is the same experience, and the experience of Ethereum is not much different. The difference is, BTC and the US dollar experience is very different.
I personally feel that the blockchain industry is an ecology. Whether it is serving one of the areas in the blockchain and ultimately building a blockchain together, it is essentially a collaborative evolution that builds a stronger consensus mechanism. Diversity provides the basis for the choice of consensus, and if there is only one technical direction, then the evolution of technology has become slow. In addition this is only a technical factor, but the blockchain system is not only as simple as technology, there is community community of interests behind.
 
Q20: What dimensions are the most important when evaluating the value of a blockchain project? What factors can be rejected one vote?
The Beginning: The Essential Elements of the Encrypted Currency Valuation Model (I send some thoughts that I wrote before) As the first truly successful decentralized e-cash system, bitcoin became the anchor of value in the industry and By far the most centralized network, Bitcoin is designed as an electronic currency that is secure, secure, and has a very low threshold of participation in the early stages.
It is early everyone can participate, and become a full node without any threshold, anyone can download bitcoin client, early mining in his computer, so in fact the realization of the low threshold of the financial services system, everyone With the freedom to join and exit, bitcoin clients have been rapidly evolving early, and if the client is a game, the Bitcoin client's distribution is a borderless game.
In P2P network, a very important core element is full node. In a P2P network, the total number of nodes basically determines the technical value of this network.
 
Why do you say that?
In the traditional database domain and distributed system, we study the consistency of the data, there are already many, all major companies have their own solutions, but few companies have tens of thousands of distributed system distributed nodes, So most of the research results are more suitable for some enterprises to solve the solution. For example, the Paxos algorithm proposed by Leslie Lamport in 1990 can achieve highly fault-tolerant requirements based on message passing. The latter algorithm is also widely used in google Chubby lock, and Chubby lock behind is widely used in Google's core design Bigtable, bigtable is to support a lot of Google's core business.
 
The realization of Bitcoin network is a fusion of technology and humanity.
In a traditional distributed network, in a large company's network, each node in many cases is due to network reasons, dropping or sending wrong messages, instead of deliberately forging information for the sake of profit.
 
The realization of bitcoin is facing a more complicated network environment, not only a more complex network environment, but also a more complicated game of humanity. In the traditional distributed network, no one will consider the introduction of incentives to allow nodes to maintain data consistency, Nakamoto was the first person to do so, and through a resource that can not be monopolized (hash function computing power ) To ensure the effective allocation of accounting rights to avoid single-point ddos ​​attacks on specific accounting nodes.
 
Bitcoin network to each distributed node in the network, the consistency of each time slice into a time interval consistency, if you look at the global currency bitcoin network, you will find each time slice and time, different The miners in calculating the different chains, in fact, is a bifurcated network, but in a 10-minute time interval, the probability that the data is modified is a Poisson distribution. The probability of the attacker's success is q, The growth of the block is exponentially declining. When the blockchain has six acknowledgments, the attacker's probability of success tends to be essentially zero.
 
If you are the full node in a Bitcoin network, then you have the largest and equal rights to the network, and you no longer have to trust third parties or give up your rights to others. At present, many other cryptocurrencies tend to be centralized. Many consensus mechanisms realize a fast transaction processing speed. In essence, they deprive participants of their equal rights and allow the network to return to a centralized network. But if we really need to hand over our rights in the blockchain network, banks may be a better choice than a lot of centralized blockchain systems.
 
At present there are about 13,000 full nodes in the bitcoin network. Due to the characteristics of the p2p network, it is very difficult to accurately count the total number of nodes in the network. These 13000 full nodes bear the accounting of the distribution and transaction of currency, and are also bits The foundation of the currency. Bitcoin is definitely a more distributed clearing network than Alipay, and unlike Alipay, Alipay is just a payment instrument that serves the renminbi system. Bitcoin's global clearing network also has its own currency system --- Bitcoin Compared to a bank, opening a bitcoin "dot" actually requires only one computer to run a full node. Therefore, the final service boundary of Bitcoin is borderless, and the service objects of banks and Alipay have boundaries.
 
Bitcoin achieved a breakthrough from 0 to 1 and completed the carriage-to-car transition (steam engine). In fact, crypto-currencies appeared behind us. In fact, we made some improvements on the basis of Nakamoto. Indeed, we have not Take the carriage again, essentially all the cryptocurrencies are in the car.
 
If we look at bitcoin from a software science perspective rather than a currency perspective, the various cryptocurrencies that appear later are essentially improvements and enhancements based on bitcoin's open-source software, which many teams make And upgrading, and not much difference, whether it is to change a mining algorithm, or add some total, a lot of bifurcation is done from 1 to 1.001 experiment, bitcoin from paper currency to electronic currency from 0 To 1 transition and fission.
 
Today, Bitcoin has the strongest network effect and the loudest brand effect. Although the technology iteration is very, very slow, some progress has been made one after another, but it can not be surpassed from the aspect of things development. , But no matter whether it will be surpassed, the emergence of bitcoin has its historical inevitability and it will certainly accomplish its historic mission. As the world's largest distributed clearing network and built-in monetary system in the future, as well as the anchor of the value in the parallel financial world in the blockchain and the boost of crazy humanity, we predict where its future highs will be Speaking of other factors aside, cryptocurrency has opened up a new era in which its market value should surpass that of the previous wave of the Internet.
 
Question 21: Blockchain whether the future is required to apply for a license to do?
Patrick Dai: From the future development of cryptocurrency, this is an inevitable.
 
Question 22: The future of blockchain in the IP field?
Patrick Dai: This still need to solve the chain and chain problems, as well as integration with the existing legal system. But purely virtual assets may not be needed, such as audio and video saved in the art and electronic formats of game props and electronic designs. But no matter what kind of industry, we have to think about, in addition to the token premium liquidity brought us by the blockchain, the blockchain really helped solve what problems?
 
Q23: Now the real consumption of blockchain project is not much, why do not wait for the project landing, re-vote? Tencent like buying now is not too late. Estimated seed round billion reasonable?
Patrick Dai: revolutionary ideas and new technology has brought endless imagination mixed with human speculation and greed.
 
Q24: Want to know how to treat EOS Q1 beta?
Patrick Dai: the specific progress did not pay attention to too many details, each project has its own position, as long as the solution to a certain area or the general needs, I personally feel that are very valuable. But we also look at the duration of the project is also to our own positioning, if the measurement of time is one day, it is trader, if it is a month, it is a short-term speculators, if it is one year, in the block chain industry is long-term investors If it is three to five years or ten years, it's the value discoverer and the leader in technological change.
 
Q25: What kind of impact can blockchain have on the economic vitality of the third and fourth tier cities today? When will have an impact?
Patrick Dai: I do not know this.

Is anyone else freaked out by this whole blocksize debate? Does anyone else find themself often agreeing with *both* sides - depending on whichever argument you happen to be reading at the moment? And do we need some better algorithms and data structures?

Why do both sides of the debate seem “right” to me?
I know, I know, a healthy debate is healthy and all - and maybe I'm just not used to the tumult and jostling which would be inevitable in a real live open major debate about something as vital as Bitcoin.
And I really do agree with the starry-eyed idealists who say Bitcoin is vital. Imperfect as it may be, it certainly does seem to represent the first real chance we've had in the past few hundred years to try to steer our civilization and our planet away from the dead-ends and disasters which our government-issued debt-based currencies keep dragging us into.
But this particular debate, about the blocksize, doesn't seem to be getting resolved at all.
Pretty much every time I read one of the long-form major arguments contributed by Bitcoin "thinkers" who I've come to respect over the past few years, this weird thing happens: I usually end up finding myself nodding my head and agreeing with whatever particular piece I'm reading!
But that should be impossible - because a lot of these people vehemently disagree!
So how can both sides sound so convincing to me, simply depending on whichever piece I currently happen to be reading?
Does anyone else feel this way? Or am I just a gullible idiot?
Just Do It?
When you first look at it or hear about it, increasing the size seems almost like a no-brainer: The "big-block" supporters say just increase the blocksize to 20 MB or 8 MB, or do some kind of scheduled or calculated regular increment which tries to take into account the capabilities of the infrastructure and the needs of the users. We do have the bandwidth and the memory to at least increase the blocksize now, they say - and we're probably gonna continue to have more bandwidth and memory in order to be able to keep increasing the blocksize for another couple decades - pretty much like everything else computer-based we've seen over the years (some of this stuff is called by names such as "Moore's Law").
On the other hand, whenever the "small-block" supporters warn about the utter catastrophe that a failed hard-fork would mean, I get totally freaked by their possible doomsday scenarios, which seem totally plausible and terrifying - so I end up feeling that the only way I'd want to go with a hard-fork would be if there was some pre-agreed "triggering" mechanism where the fork itself would only actually "switch on" and take effect provided that some "supermajority" of the network (of who? the miners? the full nodes?) had signaled (presumably via some kind of totally reliable p2p trustless software-based voting system?) that they do indeed "pre-agree" to actually adopt the pre-scheduled fork (and thereby avoid any possibility whatsoever of the precious blockchain somehow tragically splitting into two and pretty much killing this cryptocurrency off in its infancy).
So in this "conservative" scenario, I'm talking about wanting at least 95% pre-adoption agreement - not the mere 75% which I recall some proposals call for, which seems like it could easily lead to a 75/25 blockchain split.
But this time, with this long drawn-out blocksize debate, the core devs, and several other important voices who have become prominent opinion shapers over the past few years, can't seem to come to any real agreement on this.
Weird split among the devs
As far as I can see, there's this weird split: Gavin and Mike seem to be the only people among the devs who really want a major blocksize increase - and all the other devs seem to be vehemently against them.
But then on the other hand, the users seem to be overwhelmingly in favor of a major increase.
And there are meta-questions about governance, about about why this didn't come out as a BIP, and what the availability of Bitcoin XT means.
And today or yesterday there was this really cool big-blockian exponential graph based on doubling the blocksize every two years for twenty years, reminding us of the pure mathematical fact that 210 is indeed about 1000 - but not really addressing any of the game-theoretic points raised by the small-blockians. So a lot of the users seem to like it, but when so few devs say anything positive about it, I worry: is this just yet more exponential chart porn?
On the one hand, Gavin's and Mike's blocksize increase proposal initially seemed like a no-brainer to me.
And on the other hand, all the other devs seem to be against them. Which is weird - not what I'd initially expected at all (but maybe I'm just a fool who's seduced by exponential chart porn?).
Look, I don't mean to be rude to any of the core devs, and I don't want to come off like someone wearing a tinfoil hat - but it has to cross people's minds that the powers that be (the Fed and the other central banks and the governments that use their debt-issued money to run this world into a ditch) could very well be much more scared shitless than they're letting on. If we assume that the powers that be are using their usual playbook and tactics, then it could be worth looking at the book "Confessions of an Economic Hitman" by John Perkins, to get an idea of how they might try to attack Bitcoin. So, what I'm saying is, they do have a track record of sending in "experts" to try to derail projects and keep everyone enslaved to the Creature from Jekyll Island. I'm just saying. So, without getting ad hominem - let's just make sure that our ideas can really stand scrutiny on their own - as Nick Szabo says, we need to make sure there is "more computer science, less noise" in this debate.
When Gavin Andresen first came out with the 20 MB thing - I sat back and tried to imagine if I could download 20 MB in 10 minutes (which seems to be one of the basic mathematical and technological constraints here - right?)
I figured, "Yeah, I could download that" - even with my crappy internet connection.
And I guess the telecoms might be nice enough to continue to double our bandwidth every two years for the next couple decades – if we ask them politely?
On the other hand - I think we should be careful about entrusting the financial freedom of the world into the greedy hands of the telecoms companies - given all their shady shenanigans over the past few years in many countries. After decades of the MPAA and the FBI trying to chip away at BitTorrent, lately PirateBay has been hard to access. I would say it's quite likely that certain persons at institutions like JPMorgan and Goldman Sachs and the Fed might be very, very motivated to see Bitcoin fail - so we shouldn't be too sure about scaling plans which depend on the willingness of companies Verizon and AT&T to double our bandwith every two years.
Maybe the real important hardware buildout challenge for a company like 21 (and its allies such as Qualcomm) to take on now would not be "a miner in every toaster" but rather "Google Fiber Download and Upload Speeds in every Country, including China".
I think I've read all the major stuff on the blocksize debate from Gavin Andresen, Mike Hearn, Greg Maxwell, Peter Todd, Adam Back, and Jeff Garzick and several other major contributors - and, oddly enough, all their arguments seem reasonable - heck even Luke-Jr seems reasonable to me on the blocksize debate, and I always thought he was a whackjob overly influenced by superstition and numerology - and now today I'm reading the article by Bram Cohen - the inventor of BitTorrent - and I find myself agreeing with him too!
I say to myself: What's going on with me? How can I possibly agree with all of these guys, if they all have such vehemently opposing viewpoints?
I mean, think back to the glory days of a couple of years ago, when all we were hearing was how this amazing unprecedented grassroots innovation called Bitcoin was going to benefit everyone from all walks of life, all around the world:
...basically the entire human race transacting everything into the blockchain.
(Although let me say that I think that people's focus on ideas like driverless cabs creating realtime fare markets based on supply and demand seems to be setting our sights a bit low as far as Bitcoin's abilities to correct the financial world's capital-misallocation problems which seem to have been made possible by infinite debt-based fiat. I would have hoped that a Bitcoin-based economy would solve much more noble, much more urgent capital-allocation problems than driverless taxicabs creating fare markets or refrigerators ordering milk on the internet of things. I was thinking more along the lines that Bitcoin would finally strangle dead-end debt-based deadly-toxic energy industries like fossil fuels and let profitable clean energy industries like Thorium LFTRs take over - but that's another topic. :=)
Paradoxes in the blocksize debate
Let me summarize the major paradoxes I see here:
(1) Regarding the people (the majority of the core devs) who are against a blocksize increase: Well, the small-blocks arguments do seem kinda weird, and certainly not very "populist", in the sense that: When on earth have end-users ever heard of a computer technology whose capacity didn't grow pretty much exponentially year-on-year? All the cool new technology we've had - from hard drives to RAM to bandwidth - started out pathetically tiny and grew to unimaginably huge over the past few decades - and all our software has in turn gotten massively powerful and big and complex (sometimes bloated) to take advantage of the enormous new capacity available.
But now suddenly, for the first time in the history of technology, we seem to have a majority of the devs, on a major p2p project - saying: "Let's not scale the system up. It could be dangerous. It might break the whole system (if the hard-fork fails)."
I don't know, maybe I'm missing something here, maybe someone else could enlighten me, but I don't think I've ever seen this sort of thing happen in the last few decades of the history of technology - devs arguing against scaling up p2p technology to take advantage of expected growth in infrastructure capacity.
(2) But... on the other hand... the dire warnings of the small-blockians about what could happen if a hard-fork were to fail - wow, they do seem really dire! And these guys are pretty much all heavyweight, experienced programmers and/or game theorists and/or p2p open-source project managers.
I must say, that nearly all of the long-form arguments I've read - as well as many, many of the shorter comments I've read from many users in the threads, whose names I at least have come to more-or-less recognize over the past few months and years on reddit and bitcointalk - have been amazingly impressive in their ability to analyze all aspects of the lifecycle and management of open-source software projects, bringing up lots of serious points which I could never have come up with, and which seem to come from long experience with programming and project management - as well as dealing with economics and human nature (eg, greed - the game-theory stuff).
So a lot of really smart and experienced people with major expertise in various areas ranging from programming to management to game theory to politics to economics have been making some serious, mature, compelling arguments.
But, as I've been saying, the only problem to me is: in many of these cases, these arguments are vehemently in opposition to each other! So I find myself agreeing with pretty much all of them, one by one - which means the end result is just a giant contradiction.
I mean, today we have Bram Cohen, the inventor of BitTorrent, arguing (quite cogently and convincingly to me), that it would be dangerous to increase the blocksize. And this seems to be a guy who would know a few things about scaling out a massive global p2p network - since the protocol which he invented, BitTorrent, is now apparently responsible for like a third of the traffic on the internet (and this despite the long-term concerted efforts of major evil players such as the MPAA and the FBI to shut the whole thing down).
Was the BitTorrent analogy too "glib"?
By the way - I would like to go on a slight tangent here and say that one of the main reasons why I felt so "comfortable" jumping on the Bitcoin train back a few years ago, when I first heard about it and got into it, was the whole rough analogy I saw with BitTorrent.
I remembered the perhaps paradoxical fact that when a torrent is more popular (eg, a major movie release that just came out last week), then it actually becomes faster to download. More people want it, so more people have a few pieces of it, so more people are able to get it from each other. A kind of self-correcting economic feedback loop, where more demand directly leads to more supply.
(BitTorrent manages to pull this off by essentially adding a certain structure to the file being shared, so that it's not simply like an append-only list of 1 MB blocks, but rather more like an random-access or indexed array of 1 MB chunks. Say you're downloading a film which is 700 MB. As soon as your "client" program has downloaded a single 1-MB chunk - say chunk #99 - your "client" program instantly turns into a "server" program as well - offering that chunk #99 to other clients. From my simplistic understanding, I believe the Bitcoin protocol does something similar, to provide a p2p architecture. Hence my - perhaps naïve - assumption that Bitcoin already had the right algorithms / architecture / data structure to scale.)
The efficiency of the BitTorrent network seemed to jive with that "network law" (Metcalfe's Law?) about fax machines. This law states that the more fax machines there are, the more valuable the network of fax machines becomes. Or the value of the network grows on the order of the square of the number of nodes.
This is in contrast with other technology like cars, where the more you have, the worse things get. The more cars there are, the more traffic jams you have, so things start going downhill. I guess this is because highway space is limited - after all, we can't pave over the entire countryside, and we never did get those flying cars we were promised, as David Graeber laments in a recent essay in The Baffler magazine :-)
And regarding the "stress test" supposedly happening right now in the middle of this ongoing blocksize debate, I don't know what worries me more: the fact that it apparently is taking only $5,000 to do a simple kind of DoS on the blockchain - or the fact that there are a few rumors swirling around saying that the unknown company doing the stress test shares the same physical mailing address with a "scam" company?
Or maybe we should just be worried that so much of this debate is happening on a handful of forums which are controlled by some guy named theymos who's already engaged in some pretty "contentious" or "controversial" behavior like blowing a million dollars on writing forum software (I guess he never heard that reddit.com software is open-source)?
So I worry that the great promise of "decentralization" might be more fragile than we originally thought.
Scaling
Anyways, back to Metcalfe's Law: with virtual stuff, like torrents and fax machines, the more the merrier. The more people downloading a given movie, the faster it arrives - and the more people own fax machines, the more valuable the overall fax network.
So I kindof (naïvely?) assumed that Bitcoin, being "virtual" and p2p, would somehow scale up the same magical way BitTorrrent did. I just figured that more people using it would somehow automatically make it stronger and faster.
But now a lot of devs have started talking in terms of the old "scarcity" paradigm, talking about blockspace being a "scarce resource" and talking about "fee markets" - which seems kinda scary, and antithetical to much of the earlier rhetoric we heard about Bitcoin (the stuff about supporting our favorite creators with micropayments, and the stuff about Africans using SMS to send around payments).
Look, when some asshole is in line in front of you at the cash register and he's holding up the line so they can run his credit card to buy a bag of Cheeto's, we tend to get pissed off at the guy - clogging up our expensive global electronic payment infrastructure to make a two-dollar purchase. And that's on a fairly efficient centralized system - and presumably after a year or so, VISA and the guy's bank can delete or compress the transaction in their SQL databases.
Now, correct me if I'm wrong, but if some guy buys a coffee on the blockchain, or if somebody pays an online artist $1.99 for their work - then that transaction, a few bytes or so, has to live on the blockchain forever?
Or is there some "pruning" thing that gets rid of it after a while?
And this could lead to another question: Viewed from the perspective of double-entry bookkeeping, is the blockchain "world-wide ledger" more like the "balance sheet" part of accounting, i.e. a snapshot showing current assets and liabilities? Or is it more like the "cash flow" part of accounting, i.e. a journal showing historical revenues and expenses?
When I think of thousands of machines around the globe having to lug around multiple identical copies of a multi-gigabyte file containing some asshole's coffee purchase forever and ever... I feel like I'm ideologically drifting in one direction (where I'd end up also being against really cool stuff like online micropayments and Africans banking via SMS)... so I don't want to go there.
But on the other hand, when really experienced and battle-tested veterans with major experience in the world of open-souce programming and project management (the "small-blockians") warn of the catastrophic consequences of a possible failed hard-fork, I get freaked out and I wonder if Bitcoin really was destined to be a settlement layer for big transactions.
Could the original programmer(s) possibly weigh in?
And I don't mean to appeal to authority - but heck, where the hell is Satoshi Nakamoto in all this? I do understand that he/she/they would want to maintain absolute anonymity - but on the other hand, I assume SN wants Bitcoin to succeed (both for the future of humanity - or at least for all the bitcoins SN allegedly holds :-) - and I understand there is a way that SN can cryptographically sign a message - and I understand that as the original developer of Bitcoin, SN had some very specific opinions about the blocksize... So I'm kinda wondering of Satoshi could weigh in from time to time. Just to help out a bit. I'm not saying "Show us a sign" like a deity or something - but damn it sure would be fascinating and possibly very helpful if Satoshi gave us his/hetheir 2 satoshis worth at this really confusing juncture.
Are we using our capacity wisely?
I'm not a programming or game-theory whiz, I'm just a casual user who has tried to keep up with technology over the years.
It just seems weird to me that here we have this massive supercomputer (500 times more powerful than the all the supercomputers in the world combined) doing fairly straightforward "embarassingly parallel" number-crunching operations to secure a p2p world-wide ledger called the blockchain to keep track of a measly 2.1 quadrillion tokens spread out among a few billion addresses - and a couple of years ago you had people like Rick Falkvinge saying the blockchain would someday be supporting multi-million-dollar letters of credit for international trade and you had people like Andreas Antonopoulos saying the blockchain would someday allow billions of "unbanked" people to send remittances around the village or around the world dirt-cheap - and now suddenly in June 2015 we're talking about blockspace as a "scarce resource" and talking about "fee markets" and partially centralized, corporate-sponsored "Level 2" vaporware like Lightning Network and some mysterious company is "stess testing" or "DoS-ing" the system by throwing away a measly $5,000 and suddenly it sounds like the whole system could eventually head right back into PayPal and Western Union territory again, in terms of expensive fees.
When I got into Bitcoin, I really was heavily influenced by vague analogies with BitTorrent: I figured everyone would just have tiny little like utorrent-type program running on their machine (ie, Bitcoin-QT or Armory or Mycelium etc.).
I figured that just like anyone can host a their own blog or webserver, anyone would be able to host their own bank.
Yeah, Google and and Mozilla and Twitter and Facebook and WhatsApp did come along and build stuff on top of TCP/IP, so I did expect a bunch of companies to build layers on top of the Bitcoin protocol as well. But I still figured the basic unit of bitcoin client software powering the overall system would be small and personal and affordable and p2p - like a bittorrent client - or at the most, like a cheap server hosting a blog or email server.
And I figured there would be a way at the software level, at the architecture level, at the algorithmic level, at the data structure level - to let the thing scale - if not infinitely, at least fairly massively and gracefully - the same way the BitTorrent network has.
Of course, I do also understand that with BitTorrent, you're sharing a read-only object (eg, a movie) - whereas with Bitcoin, you're achieving distributed trustless consensus and appending it to a write-only (or append-only) database.
So I do understand that the problem which BitTorrent solves is much simpler than the problem which Bitcoin sets out to solve.
But still, it seems that there's got to be a way to make this thing scale. It's p2p and it's got 500 times more computing power than all the supercomputers in the world combined - and so many brilliant and motivated and inspired people want this thing to succeed! And Bitcoin could be our civilization's last chance to steer away from the oncoming debt-based ditch of disaster we seem to be driving into!
It just seems that Bitcoin has got to be able to scale somehow - and all these smart people working together should be able to come up with a solution which pretty much everyone can agree - in advance - will work.
Right? Right?
A (probably irrelevant) tangent on algorithms and architecture and data structures
I'll finally weigh with my personal perspective - although I might be biased due to my background (which is more on the theoretical side of computer science).
My own modest - or perhaps radical - suggestion would be to ask whether we're really looking at all the best possible algorithms and architectures and data structures out there.
From this perspective, I sometimes worry that the overwhelming majority of the great minds working on the programming and game-theory stuff might come from a rather specific, shall we say "von Neumann" or "procedural" or "imperative" school of programming (ie, C and Python and Java programmers).
It seems strange to me that such a cutting-edge and important computer project would have so little participation from the great minds at the other end of the spectrum of programming paradigms - namely, the "functional" and "declarative" and "algebraic" (and co-algebraic!) worlds.
For example, I was struck in particular by statements I've seen here and there (which seemed rather hubristic or lackadaisical to me - for something as important as Bitcoin), that the specification of Bitcoin and the blockchain doesn't really exist in any form other than the reference implementation(s) (in procedural languages such as C or Python?).
Curry-Howard anyone?
I mean, many computer scientists are aware of the Curry-Howard isomorophism, which basically says that the relationship between a theorem and its proof is equivalent to the relationship between a specification and its implementation. In other words, there is a long tradition in mathematics (and in computer programming) of:
And it's not exactly "turtles all the way down" either: a specification is generally simple and compact enough that a good programmer can usually simply visually inspect it to determine if it is indeed "correct" - something which is very difficult, if not impossible, to do with a program written in a procedural, implementation-oriented language such as C or Python or Java.
So I worry that we've got this tradition, from the open-source github C/Java programming tradition, of never actually writing our "specification", and only writing the "implementation". In mission-critical military-grade programming projects (which often use languages like Ada or Maude) this is simply not allowed. It would seem that a project as mission-critical as Bitcoin - which could literally be crucial for humanity's continued survival - should also use this kind of military-grade software development approach.
And I'm not saying rewrite the implementations in these kind of theoretical languages. But it might be helpful if the C/Python/Java programmers in the Bitcoin imperative programming world could build some bridges to the Maude/Haskell/ML programmers of the functional and algebraic programming worlds to see if any kind of useful cross-pollination might take place - between specifications and implementations.
For example, the JavaFAN formal analyzer for multi-threaded Java programs (developed using tools based on the Maude language) was applied to the Remote Agent AI program aboard NASA's Deep Space 1 shuttle, written in Java - and it took only a few minutes using formal mathematical reasoning to detect a potential deadlock which would have occurred years later during the space mission when the damn spacecraft was already way out around Pluto.
And "the Maude-NRL (Naval Research Laboratory) Protocol Analyzer (Maude-NPA) is a tool used to provide security proofs of cryptographic protocols and to search for protocol flaws and cryptosystem attacks."
These are open-source formal reasoning tools developed by DARPA and used by NASA and the US Navy to ensure that program implementations satisfy their specifications. It would be great if some of the people involved in these kinds of projects could contribute to help ensure the security and scalability of Bitcoin.
But there is a wide abyss between the kinds of programmers who use languages like Maude and the kinds of programmers who use languages like C/Python/Java - and it can be really hard to get the two worlds to meet. There is a bit of rapprochement between these language communities in languages which might be considered as being somewhere in the middle, such as Haskell and ML. I just worry that Bitcoin might be turning into being an exclusively C/Python/Java project (with the algorithms and practitioners traditionally of that community), when it could be more advantageous if it also had some people from the functional and algebraic-specification and program-verification community involved as well. The thing is, though: the theoretical practitioners are big on "semantics" - I've heard them say stuff like "Yes but a C / C++ program has no easily identifiable semantics". So to get them involved, you really have to first be able to talk about what your program does (specification) - before proceeding to describe how it does it (implementation). And writing high-level specifications is typically very hard using the syntax and semantics of languages like C and Java and Python - whereas specs are fairly easy to write in Maude - and not only that, they're executable, and you state and verify properties about them - which provides for the kind of debate Nick Szabo was advocating ("more computer science, less noise").
Imagine if we had an executable algebraic specification of Bitcoin in Maude, where we could formally reason about and verify certain crucial game-theoretical properties - rather than merely hand-waving and arguing and deploying and praying.
And so in the theoretical programming community you've got major research on various logics such as Girard's Linear Logic (which is resource-conscious) and Bruni and Montanari's Tile Logic (which enables "pasting" bigger systems together from smaller ones in space and time), and executable algebraic specification languages such as Meseguer's Maude (which would be perfect for game theory modeling, with its functional modules for specifying the deterministic parts of systems and its system modules for specifiying non-deterministic parts of systems, and its parameterized skeletons for sketching out the typical architectures of mobile systems, and its formal reasoning and verification tools and libraries which have been specifically applied to testing and breaking - and fixing - cryptographic protocols).
And somewhat closer to the practical hands-on world, you've got stuff like Google's MapReduce and lots of Big Data database languages developed by Google as well. And yet here we are with a mempool growing dangerously big for RAM on a single machine, and a 20-GB append-only list as our database - and not much debate on practical results from Google's Big Data databases.
(And by the way: maybe I'm totally ignorant for asking this, but I'll ask anyways: why the hell does the mempool have to stay in RAM? Couldn't it work just as well if it were stored temporarily on the hard drive?)
And you've got CalvinDB out of Yale which apparently provides an ACID layer on top of a massively distributed database.
Look, I'm just an armchair follower cheering on these projects. I can barely manage to write a query in SQL, or read through a C or Python or Java program. But I would argue two points here: (1) these languages may be too low-level and "non-formal" for writing and modeling and formally reasoning about and proving properties of mission-critical specifications - and (2) there seem to be some Big Data tools already deployed by institutions such as Google and Yale which support global petabyte-size databases on commodity boxes with nice properties such as near-real-time and ACID - and I sometimes worry that the "core devs" might be failing to review the literature (and reach out to fellow programmers) out there to see if there might be some formal program-verification and practical Big Data tools out there which could be applied to coming up with rock-solid, 100% consensus proposals to handle an issue such as blocksize scaling, which seems to have become much more intractable than many people might have expected.
I mean, the protocol solved the hard stuff: the elliptical-curve stuff and the Byzantine General stuff. How the heck can we be falling down on the comparatively "easier" stuff - like scaling the blocksize?
It just seems like defeatism to say "Well, the blockchain is already 20-30 GB and it's gonna be 20-30 TB ten years from now - and we need 10 Mbs bandwidth now and 10,000 Mbs bandwidth 20 years from - assuming the evil Verizon and AT&T actually give us that - so let's just become a settlement platform and give up on buying coffee or banking the unbanked or doing micropayments, and let's push all that stuff into some corporate-controlled vaporware without even a whitepaper yet."
So you've got Peter Todd doing some possibly brilliant theorizing and extrapolating on the idea of "treechains" - there is a Let's Talk Bitcoin podcast from about a year ago where he sketches the rough outlines of this idea out in a very inspiring, high-level way - although the specifics have yet to be hammered out. And we've got Blockstream also doing some hopeful hand-waving about the Lightning Network.
Things like Peter Todd's treechains - which may be similar to the spark in some devs' eyes called Lightning Network - are examples of the kind of algorithm or architecture which might manage to harness the massive computing power of miners and nodes in such a way that certain kinds of massive and graceful scaling become possible.
It just seems like a kindof tiny dev community working on this stuff.
Being a C or Python or Java programmer should not be a pre-req to being able to help contribute to the specification (and formal reasoning and program verification) for Bitcoin and the blockchain.
XML and UML are crap modeling and specification languages, and C and Java and Python are even worse (as specification languages - although as implementation languages, they are of course fine).
But there are serious modeling and specification languages out there, and they could be very helpful at times like this - where what we're dealing with is questions of modeling and specification (ie, "needs and requirements").
One just doesn't often see the practical, hands-on world of open-source github implementation-level programmers and the academic, theoretical world of specification-level programmers meeting very often. I wish there were some way to get these two worlds to collaborate on Bitcoin.
Maybe a good first step to reach out to the theoretical people would be to provide a modular executable algebraic specification of the Bitcoin protocol in a recognized, military/NASA-grade specification language such as Maude - because that's something the theoretical community can actually wrap their heads around, whereas it's very hard to get them to pay attention to something written only as a C / Python / Java implementation (without an accompanying specification in a formal language).
They can't check whether the program does what it's supposed to do - if you don't provide a formal mathematical definition of what the program is supposed to do.
Specification : Implementation :: Theorem : Proof
You have to remember: the theoretical community is very aware of the Curry-Howard isomorphism. Just like it would be hard to get a mathematician's attention by merely showing them a proof without telling also telling them what theorem the proof is proving - by the same token, it's hard to get the attention of a theoretical computer scientist by merely showing them an implementation without showing them the specification that it implements.
Bitcoin is currently confronted with a mathematical or "computer science" problem: how to secure the network while getting high enough transactional throughput, while staying within the limited RAM, bandwidth and hard drive space limitations of current and future infrastructure.
The problem only becomes a political and economic problem if we give up on trying to solve it as a mathematical and "theoretical computer science" problem.
There should be a plethora of whitepapers out now proposing algorithmic solutions to these scaling issues. Remember, all we have to do is apply the Byzantine General consensus-reaching procedure to a worldwide database which shuffles 2.1 quadrillion tokens among a few billion addresses. The 21 company has emphatically pointed out that racing to compute a hash to add a block is an "embarrassingly parallel" problem - very easy to decompose among cheap, fault-prone, commodity boxes, and recompose into an overall solution - along the lines of Google's highly successful MapReduce.
I guess what I'm really saying is (and I don't mean to be rude here), is that C and Python and Java programmers might not be the best qualified people to develop and formally prove the correctness of (note I do not say: "test", I say "formally prove the correctness of") these kinds of algorithms.
I really believe in the importance of getting the algorithms and architectures right - look at Google Search itself, it uses some pretty brilliant algorithms and architectures (eg, MapReduce, Paxos) which enable it to achieve amazing performance - on pretty crappy commodity hardware. And look at BitTorrent, which is truly p2p, where more demand leads to more supply.
So, in this vein, I will close this lengthy rant with an oddly specific link - which may or may not be able to make some interesting contributions to finding suitable algorithms, architectures and data structures which might help Bitcoin scale massively. I have no idea if this link could be helpful - but given the near-total lack of people from the Haskell and ML and functional worlds in these Bitcoin specification debates, I thought I'd be remiss if I didn't throw this out - just in case there might be something here which could help us channel the massive computing power of the Bitcoin network in such a way as to enable us simply sidestep this kind of desperate debate where both sides seem right because the other side seems wrong.
https://personal.cis.strath.ac.uk/neil.ghani/papers/ghani-calco07
The above paper is about "higher dimensional trees". It uses a bit of category theory (not a whole lot) and a bit of Haskell (again not a lot - just a simple data structure called a Rose tree, which has a wikipedia page) to develop a very expressive and efficient data structure which generalizes from lists to trees to higher dimensions.
I have no idea if this kind of data structure could be applicable to the current scaling mess we apparently are getting bogged down in - I don't have the game-theory skills to figure it out.
I just thought that since the blockchain is like a list, and since there are some tree-like structures which have been grafted on for efficiency (eg Merkle trees) and since many of the futuristic scaling proposals seem to also involve generalizing from list-like structures (eg, the blockchain) to tree-like structures (eg, side-chains and tree-chains)... well, who knows, there might be some nugget of algorithmic or architectural or data-structure inspiration there.
So... TL;DR:
(1) I'm freaked out that this blocksize debate has splintered the community so badly and dragged on so long, with no resolution in sight, and both sides seeming so right (because the other side seems so wrong).
(2) I think Bitcoin could gain immensely by using high-level formal, algebraic and co-algebraic program specification and verification languages (such as Maude including Maude-NPA, Mobile Maude parameterized skeletons, etc.) to specify (and possibly also, to some degree, verify) what Bitcoin does - before translating to low-level implementation languages such as C and Python and Java saying how Bitcoin does it. This would help to communicate and reason about programs with much more mathematical certitude - and possibly obviate the need for many political and economic tradeoffs which currently seem dismally inevitable - and possibly widen the collaboration on this project.
(3) I wonder if there are some Big Data approaches out there (eg, along the lines of Google's MapReduce and BigTable, or Yale's CalvinDB), which could be implemented to allow Bitcoin to scale massively and painlessly - and to satisfy all stakeholders, ranging from millionaires to micropayments, coffee drinkers to the great "unbanked".
