Bitcoin is a digital currency based on an open-source peer-to-peer software protocol that is independent of any central authority.
Bitcoin issuance and transactions are carried out collectively by the Bitcoin network. Bitcoin relies on cryptography to secure and validate transactions, and is thus often referred to as a "cryptocurrency". Bitcoins can be "mined" by users, and also transferred from user to user, directly via computer or smartphone without the need for any intermediary financial institution. Bitcoin transactions are pseudonymous and decentralized.
Proponents of Bitcoin argue that it is not susceptible to devaluation by inflation or seigniorage in the way other modern "fiat" currencies are. Nor is it associated with an arbitrary store of value such as gold, unlike hard-money or representative currencies. The Bitcoin protocol was first described by Satoshi Nakamoto a pseudonym in Each bitcoin is divided into million smaller units called satoshis. Users obtain new Bitcoin addresses from their Bitcoin software.
Creating a new address can be a completely offline process and require no communication with the Bitcoin network. Web services often generate a new Bitcoin address for every user, allowing them to have their custom deposit addresses. Transaction fees may be included with any transfer of Bitcoins. While it's technically possible to send a transaction with zero fee, As of [update] it's highly unlikely that one of these transactions confirms in a realistic amount of time, causing most nodes on the network to drop it.
For transactions which consume or produce many outputs and therefore have a large data size , higher transaction fees are usually expected. The network's software confirms a transaction when it records it in a block.
Further blocks of transactions confirm it even further. The network must store the whole transaction history inside the blockchain, which grows constantly as new records are added and never removed.
Nakamoto conceived that as the database became larger, users would desire applications for Bitcoin that didn't store the entire database on their computer. To enable this, the blockchain uses a merkle tree to organize the transaction records in such a way that client software can locally delete portions of its own database it knows it will never need, such as earlier transaction records of Bitcoins that have changed ownership multiple times.
Bitcoin has no centralized issuing authority. To ensure sufficient granularity of the money supply , clients can divide each BTC unit down to eight decimal places a total of 2.
The network as of [update] required over one million times more work for confirming a block and receiving an award 25 BTC as of February [update] than when the first blocks were confirmed.
The difficulty is automatically adjusted every blocks based on the time taken to find the previous blocks such that one block is created roughly every 10 minutes. Those who chose to put computational and electrical resources toward mining early on had a greater chance at receiving awards for block generations.
This served to make available enough processing power to process blocks. Indeed, without miners there are no transactions and the Bitcoin economy comes to a halt. Prices fluctuate relative to goods and services more than more widely accepted currencies; the price of a Bitcoin is not static. Taking into account the total number of Bitcoins mined, the monetary base of the Bitcoin network stands at over million USD.
While using bitcoins is an excellent way to make your purchases, donations, and p2p payments, without losing money through inflated transaction fees, transactions are never truly anonymous. Buying Bitcoin you pass identification, Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address. Bitcoin activities are recorded and available publicly via the blockchain , a comprehensive database which keeps a record of bitcoin transactions.
All exchanges require the user to scan ID documents, and large transactions must be reported to the proper governmental authority. When you use Bitcoin to pay for goods and services, you will of course need to provide your name and address to the seller for delivery purposes.
This means that a third party with an interest in tracking your activities can use your visible balance and ID information as a basis from which to track your future transactions or to study previous activity. In short, you have compromised your security and privacy. In addition to conventional exchanges like Bitstamp, Bitfinex, Kraken and Coinable there are also Peer to peer exchanges like localbitcoins and Paxful. Peer to peer exchanges will often not collect KYC and identity information directly from users, instead they let the users handle KYC amongst themselves.
These can often be a better alternative for those looking to purchase bitcoin quickly and without KYC delay. Mixing services are used to avoid compromising of privacy and security. Mixing services provide to periodically exchange your bitcoins for different ones which cannot be associated with the original owner. In the history of bitcoin, there have been a few incidents , caused by problematic as well as malicious transactions.
In the worst such incident, and the only one of its type, a person was able to pretend that he had a practically infinite supply of bitcoins, for almost 9 hours. Bitcoin relies, among other things, on public key cryptography and thus may be vulnerable to quantum computing attacks if and when practical quantum computers can be constructed.
If multiple different software packages, whose usage becomes widespread on the Bitcoin network, disagree on the protocol and the rules for transactions, this could potentially cause a fork in the block chain, with each faction of users being able to accept only their own version of the history of transactions.
This could influence the price of bitcoins. A global, organized campaign against the currency or the software could also influence the demand for bitcoins, and thus the exchange price. Bitcoins are awarded to Bitcoin nodes known as "miners" for the solution to a difficult proof-of-work problem which confirms transactions and prevents double-spending. This incentive, as the Nakamoto white paper describes it, encourages "nodes to support the network, and provides a way to initially distribute coins into circulation, since no central authority issues them.
Nakamoto compared the generation of new coins by expending CPU time and electricity to gold miners expending resources to add gold to circulation. Kraken opens world's first ether dark pool.
