FAQ for Beginners

What is Bitcoin?

Bitcoin is scarce, decentralized, and global digital money that cannot be censored.

Quick Advice

  • Do not respond to strangers messaging you with investment advice or offers and read how to avoid being scammed from the posts below.
  • Do not invest in Bitcoin until you do basic research, paid off all high interest debt, and have a emergency savings account of a stable fiat currency.
  • If investing do not expect to get rich quickly. You should expect to wait at least 1-2 years before taking profits. Bitcoin is currently very volatile. In the interim spend and replace Bitcoin because its a useful currency.
  • Beginners should avoid all mining and day trading until at least very familiar with Bitcoin. Mining is very professional(You cannot efficiently mine with your computer and need to buy special ASIC machines) and most people lose money day trading.
  • Never store your Bitcoins on an exchange or web wallet. Buy your bitcoins and withdraw it to your personal wallet where you actually own them instead of IOUs. Services like Robinhood and Revoult should be avoided because you cannot withdraw or use Bitcoin.
  • Make sure you make a backup of your wallet(software holding keys to your BTC) and preferably keep it offline and physical and private. Typically 12 to 24 words you write down on paper or metal. This onetime backup will restore all your keys, addresses , and Bitcoins on a new wallet if you lose your old wallet.
  • Beginners should avoid altcoins, tokens, and ICOs at least initially until they learn about Bitcoin. Most of these are scams and you should be familiar with the basics first. Bitcoin is referred to as BTC or XBT.

Bitcoin devs do NOT have consensus on blocksize

I am making this post to show to the public what the most active developers in Bitcoin, more specifically Bitcoin Core, think about block size increases. Contrary to what the public may think, there is no consensus amongst the developers regarding Gavin Andresen’s proposal to increase the block size to 20mb (Thanks to Peter Todd who brought this up during his Bitdevs NYC talk which I attended). The only devs that have come out in strong favor of this proposal is Gavin and Mike Hearn.
The rest are against any increase, prefer a smaller increase, or have not expressed an opinion either way but is asking for further research, development, and answers before we proceed. I believe that the public opinion has been highly swayed by Gavin, and we should strongly consider what others who have spent numerous hours on the protocol have to say on the topic. If any information here is inaccurate , or if there are others who I’ve missed , please let me know and I will edit them in. I’ve probably missed a lot of good comments from other developers because it is scattered all over the internet and my google-fu is not good (And please excuse my ham fisted way of labeling developer contribution by the # of commits on github. ).
I also apologize in advance if any developers feel like they are being called out. But I believe strongly that it's important to have public statements that have been made on the internet to be consolidated in one place for such an important topic. Especially when we have dangerous misconceptions where users think that increasing blocksize is a single parameter optimization with no costs like increasing the size of your race car engine. The topic of block size is not a technical issue, it is a political issue at heart. There are real trade offs involved, with people and entities who stands to gain on both sides of the debate.

Welcome to the /Bitcoin Sticky FAQ

Maybe you're here because you've received a tip on social media, or maybe you've just been hearing a lot recently about Bitcoin and are wondering what the big deal is? The following videos are a good starting point for understanding how bitcoin works and a little bit about its long term potential:
For lots of additional video resources check out the videos wiki page or /BitcoinTV . Peer-reviewed, research papers can be found here.

Where can I buy bitcoins?

You can buy or sell any amount of bitcoin (from as little as $1 worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank account. A good list of exchanges sorted by region can be found on the exchanges wiki here.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Here are a couple useful sites [bitkoin.io, preev.com] that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Where can I spend bitcoins?

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The friendly folks at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. You can view the global node distribution here.

Securing your bitcoins

With bitcoin you can "be your own bank" and personally secure your bitcoins OR you can use established companies such as Coinbase and Circle which have secured wallets where they hold the bitcoins for you and provide insurance.
If you prefer to "be your own bank" and have direct control over your coins without having to use a trusted third party, there are many options in the wallets wiki. If you would prefer easy and secure storage without having to learn computer security best practices then a hardware wallet such as the Trezor, Ledger or HW-1 is recommended.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access.
Google Authenticator Authy
Android Android

Earning bitcoins

Just like any other form of money, you can earn bitcoins by working for them. Here are a few resources for bitcoin jobs.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:
If you want to use 'bits' exclusively, just remember that there are 100 satoshis in 1 bit, and 1 million bits in one bitcoin. For more information check out the Bitcoin units wiki.

PSA: Don't fall prey to Herd Behaviour and other biases on this subreddit

I've been here awhile, and one thing that's incredibly obvious here specifically (compared to other subreddits) is that there are
Specifically, panic buying and panic selling herd behaviour, jumping on 'this sucks' or 'this rocks' comment trains because it has -3 or +6 score (cause others agree right?), and confirmation bias up the wazoo.
There are quite intelligent beings here, please remember that and don't get distracted from other wanna-be intellects. I highly recommend the /bitcoin/new instead of the Hot. Some amazing new startups posting that really need and deserve the attention but obviously don't have thousands to invest in marketing or a 50 person team of teenagers to help promote it. Some proposals that need that 1 guy who knows how to make it happen to benefit thousands.
Stop it with the insecurities. Bitcoin's userbase is tiny, let's grow together.
Thank you.

Why is Peter Todd wrecking Zeroconf security? Because he is being paid by Big Bitcoin Business.

At the Amsterdam Bitcoin Conference I spent time following Peter and his little circle of friends and business partners. I'm new to Bitcoin so it took me until now to put two and two together and understand what was really going on, but hear me out. Peter spent a lot of time talking to Lawrence Nahum who is the guy behind GreenAddress. On the first or second day they went out to dinner after the days talks were done and went out to a nice little open-air restaurant with a bunch of people from Mastercoin. I sat at a table behind them and could hear their discussions, which including GreenAdddress's transaction confirmation guarantees, and also, an agreement for Peter to do consulting work for GreenAddress. What really stood out to me was the offer to help "shape the Bitcoin ecosystem" in ways beneficial to them. Later in the conference I also overheard a similar deal between Peter and someone, I didn't catch their name, in Coinbase branded apparel. And of course as everyone knows CoinKite hired Peter to be their "Chief Naysayer" during that conference too.
What's in common with all these companies? They're all in the dangerous business of holding other peoples' Bitcoins and GreenAddress and Coinbase both offer for-profit and centralized solutions to guarantee unconfirmed transactions. I'm sure CoinKite will be doing that soon too.
It's obvious why Peter is spending all that time and energy spreading FUD about how insecure unconfirmed transactions are. GreenAddress has been spreading their own FUD. Peter has even been trying to bribe miners to switch to his so called "replace-by-fee", which is really just an attack on secure zeroconf transactions, saying some un-named "site" paid him too. Who might that be? GreenAddress, Coinbase, CoinKite? It's not hard to figure out.
Peter sure seems quite happy to attack and hold back Bitcoin whenever it suits him for the sake of his Big Bitcoin Business contracts. It's not just unconfirmed transactions either. He's been shilling for AppCoins which dump garbage into the blockchain for the sake of pump-and-dump schemes like Mastercoin and Counterparty. (quite the about face from his supposed anti-blockchain bloat positions before) Or look at his weirdly passionate opposition to a simple feature, getutxos, that's needed for Mike Hearn's decentralized fundraising platform Lighthouse. Where's that passion coming from? The heart? Or his salary from Mastercoin, Counterparty and Colored Coins? I'm sure Mastercoin wants the next Maidsafe to happen on their platform, run by and for the benefit of Mastercoin, not Hearn's truly decentralized alternative.
I agree with Peter that GHash.IO is a possible threat to Bitcoin, but what solution does he have? Getting rid of pools. His buddies at the totally discredited Hacking Distributed (remember selfish mining? yeah those guys) run with this FUD, trying to scare the Bitcoin community into making changes to get rid of pools. Sounds like a good idea right? But then I looked further into it and found out he had just been hanging out at CloudHashing. What does banning pools do to the little guy mining decentralized? It puts them out of business because they'll never find a block that's what. Just perfect for CloudHashing's "send us money and we'll run the miners" business model and also GHash.IO's.
Peter likes to talk the big talk about decentralization, but all I am seeing here is paid shilling for the benefit of Big Bitcoin Business.

With bitcoin you can be your own bank and personally secure your bitcoins or you can use trusted companies such as Coinbase and Circle which have secured wallets where they hold the bitcoins for you and provide insurance.
If you prefer to have direct control over your coins without having to use a trusted third party there are many options in the wallets wiki.
For increased security use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access.
Android 2FA
iOS 2FA

Earning bitcoins

Just like any other form of money, you can earn bitcoins by working for them. Here are a few resources for bitcoin jobs.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common ones are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (ml) or millimeter (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μl) or micrometre (μm)
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

/r/Bitcoin FAQ - Newcomers please read

Welcome to Bitcoin!

Maybe you're here because you've received a tip on social media or from /FreeBits, or maybe you've just been hearing a lot recently about Bitcoin and are wondering what the big deal is? The following videos are a good starting point for understanding how bitcoin works and a little bit about its long term potential:

What are Bitcoins worth and where can I buy them?

Bitcoins are valued at what market price people are willing to pay for them. Here is a useful site that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just google "1 bitcoin in (your local currency)".
You can buy or sell any amount of bitcoin (from as little as $1 worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank account. Top recommendations include:
US & Europe
China
Also exchanges such as those listed below can be used with bank transfer in most of Europe and US
For even more bitcoin exchanges by country location, review these exchange country listings.

Where can I spend Bitcoins?

A comprehensive list can be found at TheBitcoinPage.com but some of the key ones are below:
There are also lots of charities which accept bitcoin donations, such as Wikipedia and the RNLI. You can find a longer list here.

Merchant Resources

If you operate a business and want to accept bitcoin as a payment method, there are several options available:

Can I mine bitcoin?

Mining bitcoins can be a fun hobby but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The friendly folks at /BitcoinMining would be happy to help you out.

Securing your bitcoins

With bitcoin you can be your own bank and personally secure your bitcoins or you can use trusted companies such as Coinbase and Circle which have secured wallets where they hold the bitcoins for you and provide insurance. Be sure to only deal with reputable companies, if you have any concerns about a company's trustworthiness just ask or check their consumer reviews and ratings.
If you prefer to have direct control over your coins without having to use a trusted third party you can use personal wallets for desktops / laptops, android and iOS where you alone hold your private keys. Electrum, Mycelium and breadwallet are popular, but there are many options.
Find a wallet that works best for you
For increased security use Two Factor Authentication (2FA) everywhere it is offered, including email! (2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access). Google Authenticator and Authy are two great apps for handling 2FA.
Additional security systems such as Mycelium Entropy (for printing multi-signature paper wallets) and the Trezor Hardware Wallet are great ways to easily secure your coins. Or, you can opt to secure your bitcoin using cold storage.
Note: Do not use brainwallets unless you are an expert, they are known to be vulnerable to theft unless set up correctly.

Bitcoin dev meeting in layman's terms (2015-10-8)

Once again my attempt to summarize and explain the weekly bitcoin developer meeting in layman's terms. Link to last weeks summarization
Disclaimer
Please bare in mind I'm not a developer and I'd have problems coding "hello world!", so some things might be incorrect or plain wrong. Like any other write-up it likely contains personal biases, although I try to stay as neutral as I can. There are no decisions being made in these meetings, so if I say "everyone agrees" this means everyone present in the meeting, that's not consensus, but since a fair amount of devs are present it's a good representation. The dev IRC and mailinglist are for bitcoin development purposes. If you have not contributed actual code to a bitcoin-implementation, this is probably not the place you want to reach out to. There are many places to discuss things that the developers read, including this sub-reddit.
link to this week logs link to meeting minutes
Main topics discussed this week where:
Mempool limiting: chain limits Low-S change CLTV & CSV review Creation of bitcoin discuss mailing list
off-topic but important notice
This issue has made most JS bitcoin software vulnerable to generating incorrect public keys. "This is an ecosystem threat with the potential to cause millions of dollars in losses that needs higher visibility; though it's not a bitcoin core / bitcoin network issue. Common, critical, JS code is broken that may cause the generation of incorrect pubkeys (among other issues). Anyone who cares for a JS implementation should read that PR."
Mempool limiting: chain limits
(c/p from last week) Chain in this context means connected transactions. When you send a transaction that depends on another transaction that has yet to be confirmed we talk about a chain of transactions. Miners ideally take the whole chain into account instead of just every single transaction (although that's not widely implemented afaik). So while a single transaction might not have a sufficient fee, a depending transaction could have a high enough fee to make it worthwhile to mine both. This is commonly known as child-pays-for-parent. Since you can make these chains very big it's possible to clog up the mempool this way. The first unconfirmed transaction is called the ancestor and the transactions depending on it the descendants. The total amount of transactions is reffered to as "packages".
As said in "Chain limits" last week Morcos did write a proposal about lowering the default limits for transaction-chains. 2 use cases came up which are currently in use or happened before: As example: someone buys bitcoin from a website and can spend those bitcoin in the marketplace of the same website without waiting for confirmation in order to improve the bitcoin user-experience. This leaves a sequential transaction chain. They don't need to chain more than 5 transactions deep for this, and it falls within the proposed limits. What's not within the proposed limits is the chain of +/- 100 transactions a company had during the spam-attacks. These where simply increased activities by end-users while not enough UTXO's where available (3 to be precise)(UTXO: unspent transaction output, an output that can be used as input for a new transaction). Notably this is with the best practices of using confirmed transactions first. Ways this can be solved from the company's end is to have more UTXO's available before hand, bundling transactions (which requires delaying customer's request) or using replace-by-fee to add payees (which saves blockchain space, is cheaper in fees and gets transactions through quicker, but is not widely deployed by miners atm). Bare in mind these proposals are for default values for the memorypool, not in any way hard limits.
Sense of urgency. Quoting sipa: "my mempool is 2.5G... we better get some solution!" Current attack analysis assumes child-pays-for-parent mining, it should probably be done again without. Higher limits on number of transactions increase attack-vectors. Proposed number of transactions gets some push-back, total size limit not. Mixing default values (for example having a 50% of a 10/10 limit and 50% of a 100/100 limit) wastes bandwidth while there are too many factors that limit utility of long chains as well. 25 transaction limit ought to be enough for everyone (for now).
Review & test Limit mempool by throwing away the cheapest txn and setting min relay fee to it Provide support for Lower default limits for tx chains aka convince people 25 should be enough.
Low-S change
This is in regards to the recent malleability attack. Which is caused by a value 'S' in the ECDSA signature which can be 2 values, a high and low value and still be valid. Resulting in different transaction id's. more info A solution for this is to require nodes to have the "low-s" encoding for signatures. Downside is that it will block most transactions made by sufficiently out of date software (+/- pre-march 2014) This does not replace the need for BIP62, it only eliminates the cheap DOS attack.
95% of transactions already confirm to this, and more fixes have been applied since. BlueMatt has a node which several people are running that auto-malleates to low-s transactions. Questions whether we release it ASAP or wait for the next release and get it to a couple of miners in the meantime (possibly with auto-lowS-malleating)
Contact miners about "Test LowS in standardness, removes nuisance malleability vector" Release scheduled for the end of the month, together with likely check-lock-time-verify and possibly check-sequence-verfiy.
CLTV & CSV backport review
CLTV: checkLockTimeVerify CSV: checkSequenceVerify Both new time-related OP-codes. Been discussed heavily last week.
Concerns whether CSV will be ready enough for release later this month. There's no clarity on how things look when all 3 time related pull-requests are merged. There's a number of people still reviewing the pull-requests. Uncertainty and confusion about whether the semantics are final or not (in regards to using bits from nSequence). nSequence are 4 bytes intended for sequencing time-locked transactions, but this never got used. Now these bytes are being repurposed for a mixture of things. Currently the plan is: " bits 0..15 are the relative locktime, bit 30 determines units (0: height, 1: time w/ 512s granularity), and bit 31 toggles BIP 68 (0: on, 1: off). bits 16..29 are masked off and can take any value."
Clarification from maaku regarding nSequence for BIP68. (after the meeting he explained he was waiting for opinions, but not enough people seemed to know the issue at hand) Continue review of pull requests 6312, 6564 and 6566
Creation of bitcoin discuss mailing list
The bitcoin-dev mailing list is intented for technical discussions only. There's things that don't belong there but need to be discussed anyway. Now this is done in bitcoin-dev, but the volume of this is getting too big. There's recently also an influx of really inappropriate posts, level kindergarden.
No clarity about who are the moderators. Next week there'll be a bitcoin-discuss list created. Decisions are needed as to who'll become the moderators for that and bitcoin-dev. Decisions are needed as to what will be the list and moderation policies.
The bitcoin-discuss list will be created as well as a simple website listing all the lists and corresponding policies. A meeting is scheduled on monday to discuss the moderation and policies of said lists.

List of relevant parties we need to convince before we make the jump for bigger maxblocksize (repost from /r/bitcoin)

I think this might lead to a more constructive discussion here, considering how this place is much smaller, etc.
Now that the blocksize debate is back in the spotlight again, we all need to be reminded:
A hardfork is difficult to do under any circumstances.
That said, I don't believe that we'll need "100%" as some... ahem respectable folks in the community claim; Bitcoin is nothing without its economy and ecosystem, and what's essential to a fork is that it has the overwhelming majority of economic activity. Assuming the miners are not malicious, they will follow - and they will be onboard sooner and make the process less destructive if they see the overwhelming majority sooner.
Therefore, I propose we compile a checklist of major parties that we need to convince, in order to gain momentum on this. This list will become very useful once gavinandresen, mike_hearn and jgarzik finish their version of 0.11 / 0.11A XT for review.
I'll start with a list. The list is only a starter from my limited knowledge, so feel free to suggest changes:
Exchanges and Payment Processors
Major services/merchants that use a node
Note: Merchants that use payment processors will switch if payment processors are on board.
Major mining pools
Unfortunately Eligius can never be convinced. What a shame. =\
Wallets
Greenaddress is unlikely to be convinced.
Information website
While not essential to the ecosystem, will probably help a lot in getting the words out and hence building momentum.
Feel free to suggest additions/changes to the checklist. Let's get a roadmap so that we know what to aim for.

New press release

Hey Blackcoiners...I thought we could use another press release so I came up with this. If anyone has any suggestions on how we could improve it, feel free. Also, we need to figure out the best way to get it out there.
BlackCoin Projects Taking Crypto-Currency to the Masses
BlackCoin leads the POS revolution in crypto-currency with unprecedented projects designed to reach the mainstream user.
With roughly two months since it's inception, BlackCoin has taken the crypto-currency world by storm. One of the first crypto-currencies to use the “proof of stake” system, BlackCoin has inspired many imitators in a short time. Despite the competition, BlackCoin has established itself as the most reliable currency in this class with an active and talented development team.
One reason that BlackCoin has separated itself from the pack is the unrivaled level of support and transparency from the development team. Leaders from the community recently participated in an online broadcast known as the “BlackCast.” This rare “unmasking” of the development team has helped build confidence and make the currency seem more professional. Many topics were discussed including: real world adoption of the currency, recent technological innovations, and promotional efforts.
The BlackCoin Pool is yet another innovation that has often been imitated but never successfully duplicated. While most crypto-currencies have mining pools, which use computers to solve complex algorithms, this results in an inflationary situation where many new coins are continually being created. BlackCoin uses a “multi-pool” which instead mines other virtual currencies and uses the proceeds to purchase BlackCoins for participants. This creates a steady stream of buying pressure in the market, which protects investors.
Recently, Version 2.0 of the BlackCoin Pool was released with much success. With improved performance, a built-from scratch interface, and new features, the pool has been popular within the mining community. As more miners join on a daily basis, the price support for the currency continues to expand.
Perhaps the most exciting development in recent days is the announcement that BlackCoin hired one of the leading tech PR agencies in the industry to promote the coin. Within a few days, the funds for the 90-day PR campaign were raised by the community, illustrating the level of involvement and confidence that it offers. The goal is to take BlackCoin into the mainstream and introduce it to new users. While Bitcoin has done a great job of illustrating the benefits of digital currency to millions of early adopters, BlackCoin aims to take that to the next level. With faster confirmation times, BlackCoin is the ideal choice for retail businesses who wish to offer their customers another way to pay.
With retail adoption on the horizon, BlackCoin has also partnered with a leading point of sale company called Coinkite. Coinkite makes it possible for consumers to load debit cards with BlackCoin, Litecoin, and Bitcoin. Their funds can then be spent at a growing roster of merchants from around the world. While other currencies typically take several minutes to confirm, BlackCoin transactions are typically completed in a few seconds, making it the ideal partner for Coinkite.
With so many projects on the horizon, it's easy to see why investors who missed out on the massive returns of Bitcoin are lining up to get involved with BlackCoin. The most popular method of purchasing the currency is by first purchasing Bitcoin and using that to buy BlackCoin on exchanges like Mintpal.com and Cryptsy.com. BlackCoin has also recently been added to the popular service Vault of Satoshi, which allows investors to buy directly with USD and other currencies. With huge returns and large volume, BlackCoin is attracting a new type of investor to the crypto-currency world. It's only a matter of time until it's accepted around the world, and investors who get in early reap the benefits.

More information on the Renewable Energy consumption of Bitcoin and the environmentally friendly alternative BlackCoin TL:DR

The amount of electricity required to maintain Bitcoin’s security is legendary. Its miners are scouring the globe searching for areas with the least-expensive electricity rates.
Unfortunately, these areas are where the least expensive renewable-energy resources exist in the world.
Links are provided below to the references to back up the claims made here. This document will be updated as needed based on your comments below.
It has been estimated that the additional electricity required to maintain BlackCoin’s cooperative minting network is much less than three one-thousands ( 3 / 1000 ) of what is now used to run an equivalent sized competitive Bitcoin mining network. Bitcoin’s current electrical consumption equipment arms race is gobbling up irreplaceable, renewable-energy resources in areas where they provide the less expensive renewable energy options bar none.
A recent study cited in the Wall Street Journal shows that the hash rate required for Bitcoin’s security last fall was one one-sixtieth (1 / 60) of what it is now. This hash rate inflation has been fueled by the tremendous profitability of large scale corporate mining operations, which have produced the mining technology arms race.
The largest known corporate Bitcoin mining operation is reported to be housed in a warehouse in Central Washington State where it takes advantage of the US’s lowest electricity rates bar none. The Spokane Review recently reported that a handful of additional competitors are now about to pop up.
Washington State is the leader in hydroelectric generation with 29% of the total national capacity according to the US Energy Information Administration. It is 10th in wind energy production. Nevertheless, the whole state still has the lowest residential electric rates in the country.
The New York Times reported on a similar setup in Iceland, which may have the least expensive electricity of any country in the world. It is powered by hydro and geothermal resources.
These corporate mining operations compete against each other for the right to enter the next ledger page into the Bitcoin blockchain. The startups that produce the otherwise useless mining equipment are forced to make outrageous claims for their latest drawing board designs to get preorder payments to finance their production as has been well documented by CoinDesk in numerous articles.
Are we about to repeat the environmental disasters that followed the 1849 California Gold Rush and the wildcatting boom that began with the Spindletop oil gusher? This trend will continue as long as the Bitcoin mining technology continues to improve at breakneck speed driven by the profitability resulting from the squandering of these irreplaceable resources.
It took three and a half years after Satoshi Nakamoto launched Bitcoin in January 2009 before Sunny King in August 2012 to launch Peercoin, the first environmentally friendly cryptocurrency. However, Peercoin is designed to be the savings account complementing the best environmentally friendly checking account cryptocurrency. The market has been trying since then to settle on the best environmentally friendly challenger for Bitcoin.
The Russian crypto developer rat4 launched BlackCoin on February 24, 2014 at 6:00 UTC after making the customary announcement on February 16 on the Bitcoin Forum. Startup crypto exchange Mintpal quickly recognized the potential of rat4’s improvement of the design of the innovative Mintcoin protocol.
This helped catapult BlackCoin into 19th place in market cap by the start of April. BlackCoin obtained its current 10 th place position after Coinkite chose Blackcoin to add to its terminals in June joining Bitcoin and Litecoin.
Sunny King’s protocol has now been tested on many environmentally friendly alternatives. The market has now chosen BlackCoin to be checking account to Peercoin’s saving account.
The Bitcoin MIT Project will provision every undergraduate at that institution with $100 worth of bitcoins in the fall semester as an experiment. The proposed BlackCoin MIT Airdrop is currently being discussed by the Blackcoin Community on its reddit page. The proposal calls for provisioning each MIT graduate student with $100 of the best environmentally friendly alternative to Bitcoin in the best technology crucible in the world.
It appears from the MIT announcement that the MIT Kerberos & Internet Trust Consortium may have been used as the vehicle for obtaining tax exempt fiat donations. Therefore, should the newly formed BlackCoin Foundation ask the Trust to set up a donation account and let the environmental community try to raise the less than $1 million required to fund the MIT Airdrop.

TL:DR Some elements of the recant, surreptitious Blackcoin pump

This story of how Blackcoiners started to put together the infrastructure that got us to where we are today begins with the early establishment of the relationship between the coin and Mintpal. Mintpal believed in the coin from the start and quickly implemented it giving us a running start.
BC is now their highest volume offering. The relationship has been so good for us that some Blackcoiners now refer to it as Blackpal. The good relationship has been mutual. Mintpal put up the remaining 5 BTC in the last few days that was required by CoinKite to implement the coin. The surreptitious ability of the community in the last few days to meet the goals set by the dev team in this case obviously impressed some resent investors.
Blackcoin is a simple hybrid coin that was the first to go 100% PoS and was distributed in a fair way. There was no premine. This is why we think we deserve have our #9 in market cap at this point in our development.
Peercoin was the first hybrid coin, currently #4 in market cap, but it is not nearly ready to go 100% PoS any time soon.
NXT is 100% PoS, currently #6 in market cap, but it was not a hybrid coin. Sunny King recruited a small group of investors who essentially received premined coins in exchange for the bitcoins they put up. Some people believe this was not a fair distribution process.
While Ripple, #3 in market cap, is not technically a PoS coin, it takes an expert to try to understand the difference.
Obviously, the market is rewarding coins that are not based on Bitcoin’s PoW model.
Also, NXT is not a simple coin. It has all kinds of bells and whistles that are much too complicated for the novice user to even try to understand. Trying to explain a PoS coin is a great enough challenge.
Some people do not consider Ripple to be coin and do not consider it to be a rival for either Bitcoin or Litecoin..
Blackcoin's hybrid phase has already ended. We believe the mining phase gave us a fair distribution. Blackcoin is a simple coin like Bitcoin and Litecoin, currently #1 and #2 in market cap. .
We believe that the astronomical cost of mining hardware and the electricity require to maintain PoW coins is pushing their price down as the miners dump to stay in business.
These are the fundamental crypto attributes that has brought Blackcoin to where it is today. A press release was widely distributed on Wednesday that was used to produce over 200 stories on websites like this one:
http://cryptocrimson.com/2014/04/blackcoin-soaring-popularity-price/
Here is Coin Cartel’s updated blog post based on the press release and subsequent BC price action:
http://www.coincartel.net/2014/04/11/blackcoin-2014/
Here is the Friday link announcing the pre ordering of the BlackCoin Wallet Card.
https://bitcointalk.org/index.php?topic=469640.msg6176685#msg6176685
The card has a USB dangle containing the light weight wallet.
Here a link to a UK blog carrying another announcement of the Blackcoin lightweight wallet software:
http://thebitcoinnews.co.uk/tag/cryptoarticles/
It is now further down on the webpage. Here is what it says:
Over the past few months, we have seen several crypto currencies develop some sort of desktop lightweight wallet. Coins like DigitalCoin and WorldCoin, but you can now add BlackCoin to that list.
Although adding BlackCoin to the list might be a tad premature, as the lightweight client is only starting development as of today.
The project itself will be open sourced, and a GitHub link is available (click here). The developer , called nov3a4 , is expecting to have the client ready for testing next weekend.
The reason why project like a lightweight wallet are important, is because users won’t have to download a huge amount of data in order to synchronize with the BlackCoin network.
The press release and the announcement of the BlackCoin Waller Card were obviously intended to pump the coin.
Here are Soepkip’s instructions to us to raise Prelude BC volume from 0 to 50 BCT in 24 hours to compensate them for fully implementing BC on Mullah:
https://bitcointalk.org/index.php?topic=469640.msg6188259#msg6188259
The goal was met in less than 12 hours. This turned out to be another surreptitious aspect of the pump that obviously convinced many people that Blackcoin now has an effective community supporting it. It was shortly after this goal was met that BC broke above 20 k satoshi.
I have not covered here the latest developments in Blackcoin multipool mining. While the mining of BC itself has finished, some miners still want to have the coins to hold. They can join the effort and be paid in BC that are purchased on the open market using the results of their work. If they hold, it reduced the public BC supply. It is neutral for the supply if they sell. This is unlike the case with PoS coins, where we believe the professional miners are pushing down the price to make a living.
This is a rough draft. Please proofread and report any corrections or additions that you think I have made or left out.

Why Increased Transaction Fees And Off-Blockchain Services Are Not The Answer

It seems like most people agree that most Bitcoin transactions should occur off blockchain through third party services. The development team of Bitcoin also seems to think increasing transaction fees dynamically as demand increases will help keep the size of blocks under control.
The thing is, don't these 2 solutions completely go against what Bitcoin is about? By dynamically raising the transaction fee on Blockchain transactions, it becomes too much of a burden for people to use it for any form of purchase. People will continue to use the blockchain until it becomes too unreasonably high for purchases- it will still get flooded until it becomes impractical for anything except huge transactions. We'll probably still use it whether the fee is $0.10 or $1, but eventually it will become much too high for anything. If people are forced to use a third party service to pay with Bitcoin, then what makes it any better than Paypal or credit/debit cards? The service can still keep track of everything you buy, deny service to some markets, charge fees on your purchases, and you have to trust them with your money.
If we go with these 2 solutions instead of raising the maximum size of a block, Bitcoin will lose most of its values as a payment network. If I need to send $500 to a blockchain service at a time to avoid high fees on my $10-100 purchases, what is the point? It defeats the purpose of Decentralization since i have to trust the service not to scam me, track me, or prevent purchases. I can't send purchases without transaction fees since these services will likely charge something(and the blockchain would be worse). The security would not be good either, as passwords/cards/accounts can be compromised, so it would require the same protection that credit and debit cards require.
Transaction fees exist to:
  1. prevent malicious spam
  2. pay miners once mining rewards diminish
The current fees already accomplish this as most transactions with fees we see are legitimate and not intended to flood the network. Miners currently do not need more fees as most of the incentive comes from the 25 BTC block reward.
Please do not force most transactions to occur off blockchain with the burden of high fees. It completely defeats the purpose of Bitcoin and makes it no better than what we currently have. Doing this turns Bitcoin into a system that requires trust, has significant fees, and is no longer secure. Raising the block size limit when necessary is a much better solution. Thanks.
edit: https://en.bitcoin.it/wiki/Scalability
The Bitcoin network itself can easily support much more activity, so I don't see the point in limiting it. I feel like people being able to control their money is more important than being able to run a node on a home computer on a slow internet. With Gigabit internet spreading rapidly, Bitcoin can easily support thousands of transactions a second.
edit #2: I'm not against off blockchain services that make Bitcoin easier(ie coinkite cards) or provide services like escrow, I just don't want them to be the only way to work with Bitcoin in smaller amounts.

FAQ For Newcomers

August 9th, 2014: With the amount of projects that have been in constant development, this FAQ is somewhat out of date. While information about fundamentals of the coin remains the same and can be found here, there is much that has changed since then. In the meanwhile, please see the projects list here for a taste of the enormous development efforts of the BlackCoin community, and feel free to follow the subreddit to keep on track with new updates:
http://www.reddit.com/blackcoin/comments/27lz3h/blackcoin_projects_overview/

How to obtain BlackCoin? [E]
Why BlackCoin instead of competing Proof of Stake coins? [F]

TL/DR Version: [H]

What is BlackCoin? [A]

BlackCoin is a cryptocurrency based on many of the ideas contained within the original Bitcoin protocol, but with a few very important changes. Being only a couple of months old, it is a relatively new currency, but has been experiencing rapid growth. It is already in the top 10 cryptocurrencies by market cap.

What separates BlackCoin from other cryptocurrencies? [B]

There are a few main advantages to BlackCoin that separate it from most other cryptocurrencies. To ensure a fair distribution of coins, BlackCoin was initially distributed through a Proof of Work phase, the same method that Bitcoin uses to generate coins and secure the network.
That period is now over, and BlackCoin has transitioned entirely to PoS, or Proof of Stake. This allows lightning fast confirmation times, which can average as fast as 10 seconds each. In comparison, bitcoin averages 10 minutes per confirmation and litecoin clocks in at 2.5 minutes. These faster confirmation times can provide an extraordinary advantage for merchant adoption, as well as greatly improving the user experience.

Why Proof of Stake? [C]

Proof of Work was a fantastic innovation that formed the backbone of the original Bitcoin protocol. The idea is that by solving a computationally intensive math problem, one can prove the effort they've done to secure the protocol. This is how a blockchain is generated, and the effort that is required to perform this computations contribute to a coin's scarcity and value.
However, proof of work eventually becomes an extraordinarily expensive system. To secure the bitcoin network at the current market value costs about $1.8 million dollars, every single day. Most of this money is leaving the system to pay for energy costs and specialized computer equipment, much of which is done by huge computer farms. Even worse, when the value of a bitcoin increases, so does this cost. The hypothetical "$10,000 bitcoin" would cost $13 billion per year to maintain. While some of this may be mitigated by a reward "halving" or two in 3-7 years time, decreasing this reward too substantially creates a potential security risk.
Proof of Stake solves this issue in a very elegant way. Rather than using computer power as a scarce resource to generate security, Proof of Stake uses the scarcity of the coin itself. A user may choose to "stake" his coins to generate the next block in the chain, and his chance of doing so is basically proportional to the weight of his own coins.
With Proof of Work, a user can attack a network if he holds 51% of the current computer power, but to do so with Proof of Stake, that user would need a large shares of the overall coins. Acquiring this number of coins would be very difficult and expensive, and such an individual would have little incentive to attack the network as this would hurt the value of his own coins. As such, a Proof of Stake system is secured through basic economic facts rather than mass computing power.
While this is still a very contentious issue, the superior environmental and economic efficients of Proof of Stake lead many here to believe that it could be the future of cryptocurrency.

What other reasons are there to pick up some BlackCoin? [D]

There are many interesting coins out there, but BlackCoin strives to be superior in all areas. The combination of Proof of Stake and fast transaction times allow BlackCoin to excel both as a long-term store of value and for day-to-day transactions, a rare combination. But the coin also has a strong community and a rapidly developing infrastructure.
The coin's original developer has continued to work on the coin and make sure new applications are secure, even going so far as to point out a potential vulnerability in a competing coin. There is a dedicated community manager and many others who have been helping BlackCoin to grow and thrive.
Further, there are many new and exciting projects going on with BlackCoin, and it can even be difficult to keep track of it all. The most famous of these projects is the Blackcoin mining pool (http://blackcoinpool.com/), which allows miners to group together to mine other Proof of Work coins and use the profits to purchase BlackCoin, allowing this value to be absorbed into the BlackCoin economy. But don't be confused - the coin wasn't built around the idea of the mining pool, it's just one of the many great community developments that have sprung up to support it.
There have been other major developments recently as well. BlackCoin was recently accepted to be part of CoinKite's point of sale system, a huge step which will make it easy for both physical and online merchants to accept BlackCoin. The Black Coin Card (www.blackcoincard.com) is another effort which will make it very simple for anyone to get started using BlackCoin. Even a press release was sent out today to spread the word about BlackCoin: http://www.prweb.com/releases/2014/04/prweb11772516.htm. The community brings more and more ideas each day to support and promote BlackCoin.

How to obtain BlackCoin? [E]

Just like any cryptocurrency at the moment, it can take a little effort to get started, but once you have some cryptocurrency to your name, it isn't too hard.
The best way at the moment to acquire BlackCoin would be to buy Bitcoin and send those to an exchange to convert to BlackCoin. BitStamp.net is one of the largest exchanges between USD and Bitcoin, while CoinBase is also an option for U.S. customers. Once you have bitcoin in your possession, you can convert them to BlackCoin pretty quickly. Just send them to an exchange like MintPal and you can buy them at the present market rate.
Unfortunately, it can be a bit slow to get Bitcoin with the above method, but it's probably the best. If you want greater speed, you could try localbitcoins.com or finding someone directly to trade with (perhaps another reddit user). However, you may pay a significant premium over the market rate this way (15%+) and have to be careful of scams.
For the miners out there, you can't mine BlackCoin directly, but you can join the BlackCoin pool which mines the most profitable coins and uses them to purchase BlackCoin. Another user made a video explaining how to get started here: http://www.reddit.com/blackcoin/comments/23dy88/a_video_on_how_to_get_set_up_for_new_members/ (But make sure you are pointed at the updated address, stratum+tcp://useast.blackcoinpool.com:3333 for scrypt as I write this, stratum+tcp://useast.blackcoinpool.com:4444 for SHA).

Why BlackCoin instead of competing Proof of Stake coins? [F]

Some way wonder why they should obtain BlackCoin when coins like NXT and Peercoin have been around longer. Of course, this is always up to an individual to decide, but I feel there are strong reasons to support BlackCoin instead.
I think PeerCoin was a great idea for a coin and was the original pioneer of the Proof of Stake/Proof of Work concept. It is still in a combination phase between the two, slowly transitioning to a pure proof of stake coin. But it is different in its goals from BlackCoin.
Peercoin was designed to be the sort of coin that you use as a store of value, but is also specifically designed not to be used for day to day transactions. It uses a slow transaction confirmation time of 10 minutes per block and a very high fixed fee rate for transactions at .01 PPC per kilobyte. It is intended to be more of a complementary coin to something like Bitcoin rather than a day to day currency.
NXT is another coin which is operating as completely Proof of Stake, but there are some important differences between the two coins. BlackCoin is currently about twice as fast as NXT in terms of average confirmation speed and was based on the original Bitcoin Protocol. In comparison, NXT was instead built on its own code base. This may allow some potential positive changes, but also means that NXT is more likely to introduce new bugs or exploits that were not a part of its tried-and-true predecessors.
But one of the biggest differences can be found in the initial coin distribution. BlackCoin was launched with a brief initial Proof of Work phase and no pre-mine. Although this phase is much shorter than the one implemented by Peercoin, it was announced a week in advance to give all miners and buyers an equal and fair opportunity to claim the coin. In contrast to this method, NXT was distributed based on Bitcoin payments to an account set up by the developer. The period for purchasing NXT was prematurely cut off 6 weeks early without any warning. See here for more information:
https://bitcointalk.org/index.php?topic=303898.msg3620944#msg3620944
Another important component of any cryptocurrency that truly cannot be understated is the community that supports, builds infrastructure for, and spreads awareness of the coin to increase both its utility and adoption rate. It is this very factor that I feel has played a major role in bringing Bitcoin to where it is today, with a multi-billion dollar market cap. While this is a largely subjective area, I feel that BlackCoin has one of the strongest communities, especially for a very young coin, with several new projects springing up every few days. Contrastingly, it appears that NXT has some schisms within the community as can be seen here, splitting into two different forums:
https://nextcoin.org/index.php/topic,4621.0.html
However, bear in mind that this is my own view on the situation as an outsider with limited involvement, and it is always best to do your own research if time permits.

Where can I talk to others about BlackCoin? [G]

There are a few places to talk about BlackCoin, news, and upcoming developments. First, where you are now, the reddit community has been growing very quickly:
http://www.reddit.com/blackcoin/ Make sure to check the sidebar for many more websites.
https://bitcointalk.org/index.php?topic=469640.0 This is the bitcointalk thread. This thread has historically had the most information of any forum, but it's quite a slog to read through. Worth checking up on if you don't want to miss anything though.
http://blackcointalk.com/ The "official" forums.

TL/DR Version: [H]

Blackcoin is a cryptocurrency. It's pretty new, but it's pretty great. It uses Proof of Stake, so it's efficient. It's also lightning fast. Bitcoin is slow and expensive to secure. Proof of Stake = the future. BlackCoin = the future. The community here is amazing. BlackCoinPool. BlackCoinCard. Press. Hype. CoinKite. New projects all the time. Don't get left in the dust. Blackcoin is the best in all areas. Speed, store of value, economics, efficiency, community, developers, got it all. Buy some.

[dev] Transaction Malleability Strikes Back

Okay, the headline's over dramatic, but "Transaction Malleability is a bit inconvenient" is less catchy. As you may be aware, there's an ongoing transaction malleability attack against Bitcoin at the moment. Due to how the signatures on transactions work, there are two different valid values for one of the variables (S), and these can be calculated from each other. Someone is switching these values over in relayed transactions; the result is an entirely valid transaction, but as it's constructed differently, it has a different transaction ID (which is the SHA256 hash of the serialised transaction).
I've just gone over half the audiences' heads haven't I?
Bad people are being silly with Bitcoin transactions and making it hard to identify transactions.
How does this relate to Dogecoin, I hear you ask? Well, in a number of ways:
  1. There's a similar issue in Bitcoin Core 0.9 and below (which Dogecoin Core 1.8 is based on), about how signatures are stored (DER signature format for those who want technical details), which Dogecoin Core 1.10 fixes, so mostly I'm using this to motivate people to upgrade once we hit release.
  2. The same issue is in Dogecoin Core, including 1.10. That means we'll need to remove it at some point, although that's not trivial. There is a Bitcoin standard (BIP 62) for dealing with this, but it's not been enabled (I believe issues with unusual but valid transactions being broken).
  3. I've been spending bits of this week finishing off adding support for BIP 66 (the DER signature format fix) for bitcoinj. The main bulk of that has been submitted and is awaiting review, although it's not actually enabled yet. This also introduces a lot of architecture needed for other transaction malleability fixes.
  4. If you've ever heard me say we can't use CATE yet because of transaction malleability, this is what I mean!
Obvious question, what does this mean for the average shibe, and what do you need to do? Well, generally it shouldn't really have a lot of impact, however if you're sending a transaction on the Bitcoin block chain, don't presume the transaction ID it's sent with is the final one. All block explorers I'm aware of let you search by address, which you should use instead. Once a transaction is mined it will be "locked in" and can't change, but until then (i.e. until the first confirmation) it can change ID. I'll let you know as I see more developments.
The other big activity going on has been the resurrection of Dogeparty. patricklodder has added a mirror of the Dogeparty wallet with funding from sporklin, go hug them both if you're a Dogeparty user! coinwarp is working on an updated version of Dogeparty based on a more recent version of Counterparty, which brings me to what I've done with the other half of the week.
Recent versions of Counterparty depend on a feature called "searchrawtransactions" which was submitted to Bitcoin Core but never merged. As such, it's not part of Dogecoin Core 1.10, so I've been dusting that work off and updating it. I have a basic patch done (https://github.com/rnicoll/dogecoin/tree/1.10-branding-searchrawtransactions), but this close to release it will probably not make it into 1.10 itself, and instead I'll do a separate client with the extension. I'll also raise it as a pull requests against Bitcoin Core, and see if we can get it into their code, so maintenance happens above us :-D
1.10 remains in a stabilisation state, I'm expecting we'll have a release candidate later this month. bitcoinj work is primarily waiting on Mike being available to review code (and he's tied up with the Bitcoin block size debacle of course), there's minor improvements going on to libdohj and python-altcoinlib. Think that covers everything!
Updates should be back on schedule from here on, so expect the next on the 18th.
Have a great fortnight everyshibe!
