	New coins are slowly [[Mining\|mined]] into existence by following a mutually agreed-upon set of rules. A user [[Mining\|mining]] bitcoins is running a software program that searches for a solution to a very difficult math problem the difficulty of which is precisely known. This difficulty is automatically adjusted on a predictable schedule so that the number of solutions found globally for a given unit of time is constant: the global system aims for 6 per hour. When a solution is found, the user may tell everyone of the existence of this newly found solution along with other information packaged together in what is called a "[[Block\|block]]". The solution itself is a [[Proof of work\| proof-of-work]] or PoW. It is hard to find, but easy to verify.

	Blocks create 12.5 new bitcoins at present [~~October 2016~~]. This amount, known as the block reward, is an incentive for people to perform the computation work required for generating blocks. Roughly every 4 years, the number of bitcoins that can be "mined" in a block reduces by 50%. Originally the block reward was 50 bitcoins; it halved in November 2012; it then halved again in July 2016. Any block that is created by a malicious user that does not follow this rule (or any other rules) will be rejected by everyone else. In the end, no more than 21 million bitcoins will ever exist.

	Because the block reward will decrease over the long term, miners will some day instead pay for their hardware and electricity costs by collecting [[Transaction_fee\|transaction fees]]. The sender of money may voluntarily pay a small transaction fee which will be kept by whoever finds the next block. Paying this fee will encourage miners to include the transaction in a block more quickly.

	To guarantee that a third-party, let's call her Eve, cannot spend other people's bitcoins by creating transactions in their names, Bitcoin uses [[Wikipedia:Public-key_cryptography\|public key cryptography]] to make and verify digital signatures.

	When it comes to the Bitcoin network itself, there are no "accounts" to set up, and no e-mail addresses, user-names or passwords are required to hold or spend bitcoins. Each balance is simply associated with an address and its public-private key pair. The money "belongs" to anyone who has the private key and can sign transactions with it. Moreover, those keys do not have to be registered anywhere in advance, as they are only used when required for a transaction. Transacting parties do not need to know each other's identity in the same way that a store owner does not know a cash-paying customer's name.

	~~A [[Address\|Bitcoin address]] mathematically corresponds to a public key and looks like this:~~

	~~:1PHYrmdJ22MKbJevpb3MBNpVckjZHt89hz~~

	Each person can have many such addresses, each with its own balance, which makes it very difficult to know which person owns what amount. In order to protect his [[Anonymity\|privacy]], Bob can generate a new public-private key pair for each individual receiving transaction and the Bitcoin software encourages this behavior by default. Continuing the example from above, when Charlie receives the bitcoins from Bob, Charlie will not be able to identify who owned the bitcoins before Bob.

	~~===CoinJoin===~~

	[[CoinJoin]] open source project allowing bitcoin users to maintain their privacy. In each CoinJoin transaction, the input bitcoins are exchanged instantly for unrelated bitcoins sent by another CoinJoin participant. No trail is left. No centralized authority can record this transaction.

	===Capitalization / Nomenclature===		===Capitalization / Nomenclature===

	Since Bitcoin is both a currency and a protocol, capitalization can be confusing. Accepted practice is to use ''Bitcoin'' (singular with an upper case letter B) to label the protocol, software, and community, and ''bitcoins'' (with a lower case b) to label units of the currency.		Since Bitcoin is both a currency and a protocol, capitalization can be confusing. Accepted practice is to use ''Bitcoin'' (singular with an upper case letter B) to label the protocol, software, and community, and ''bitcoins'' (with a lower case b) to label units of the currency.

	~~==Where to see and explore==~~

	You can directly explore the system in action by visiting [https://btc.com/ BTC.com], [https://www.biteasy.com/ Biteasy.com], [https://blockchain.info/ Blockchain.info], [http://btc.blockr.io/ Blokr.io Bitcoin Block Explorer] or [https://blockexplorer.com/ Bitcoin Block Explorer].
	~~The site shows you the latest blocks in the block chain. The [[Block_chain\|block chain]] contains the agreed history of all transactions that took place in the system.~~
	Note how many blocks were generated in the last hour, which on average will be 6. Also notice the number of transactions and the total amount transferred in the last hour (last time I checked it was about 64 and 15K).
	~~This should give you an indication of how active the system is.~~

	~~Next, navigate to one of these blocks.~~
	The block's [[hash]] begins with a run of zeros. This is what made creating the block so difficult; a hash that begins with many zeros is much more difficult to find than a hash with few or no zeros. The computer that generated this block had to try many ''Nonce'' values (also listed on the block's page) until it found one that generated this run of zeros.
	~~Next, see the line titled ''Previous block''. Each block contains the hash of the block that came before it. This is what forms the chain of blocks.~~
	Now take a look at all the transactions the block contains. The first transaction is the income earned by the computer that generated this block. It includes a fixed amount of coins created out of "thin air" and possibly a fee collected from other transactions in the same block.

	~~Drill down into any of the transactions and you will see how it is made up of one or more amounts coming in and out.~~
	Having more than one incoming and outgoing amount in a transaction enables the system to join and break amounts in any possible way, allowing for any fractional amount needed. Each incoming amount is a past transaction (which you can also view) from someone's address, and each outgoing amount is addressed to someone and will be part of a future transaction (which you can also navigate down into if it has already taken place.)

	~~Finally, you can follow any of the [[Address\|addresses]] links and see what public information is available for them.~~

	To get an impression of the amount of activity on the Bitcoin network, you might like to visit the monitoring websites [[Bitcoin Monitor]] and [[Bitcoin Watch]]. The first shows a real-time visualization of events on the Bitcoin network, and the second lists general statistics on the amount and size of recent transactions.

	~~===How many people use Bitcoin?===~~

	This is quite a difficult question to answer accurately. One approach is to count how many bitcoin clients connected to the network in the last 24 hours. We can do this because some clients transmit their addresses to the other members of the network periodically;

	*In September 2011, this method suggested that there were about {{formatnum:60000}} users.

	*In October 2014, according to [https://www.coindesk.com/state-of-bitcoin-q3-2014-report-maturing-ecosystem-price-pressure/ Coindesk report] there were more than 7.5 million bitcoin wallets.

	*In October 2016, according to [https://Blockchain.info blockchain.info] user counts based on Blockchain wallet, there are about 8.8 mln registered Bitcoin users on its platform. [https://cointelegraph.com/news/counting-them-all-how-to-figure-out-actual-number-of-bitcoin-users Cointelegraph report]

	*According to [https://blockchain.info/charts/my-wallet-n-users blockchain.info], from October 2016 till January 2018 the Bitcoin user base has almost tripled for total of 22 million users.
