It is the first decentralizeddigital currency, as the system works without a central bank or single administrator. The network is peer to peer and transactions take place between users directly through the use of cryptography, without an intermediary. These transactions are verified by network nodes and recorded in an immutable public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto1. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,1. As of February 2. Credit Card Domain Knowledge Pdf FileResearch produced by the University of Cambridge estimates that in 2. Etymology. The word bitcoin first occurred and was defined in the white paper1. October 2. 00. 8. It is a compound of the words bit and coin. The white paper frequently uses the shorter coin. There is no uniform convention for bitcoin capitalization. Some sources use Bitcoin, capitalized, to refer to the technology and network and bitcoin, lowercase, to refer to the unit of account. The Wall Street Journal,1. The Chronicle of Higher Education,2. Oxford English Dictionary1. Units. The unit of account of the bitcoin system is bitcoin.

On 1. 8 August 2. In November that year, a link to a paper authored by Satoshi Nakamoto titled Bitcoin A Peer to Peer Electronic Cash System1. Nakamoto implemented the bitcoin software as open source code and released it in January 2. The identity of Nakamoto remains unknown. In January 2. 00. Satoshi Nakamoto mined the first ever block on the chain, known as the genesis block, for a reward of 5. Embedded in the coinbase of this block was the following text The Times 0. Jan2. 00. 9 Chancellor on brink of second bailout for banks. This note has been interpreted as both a timestamp of the genesis date and a derisive comment on the instability caused by fractional reserve banking. One of the first supporters, adopters, and contributors to bitcoin was the receiver of the first bitcoin transaction, programmer Hal Finney. Finney downloaded the bitcoin software the day it was released, and received 1. Nakamoto in the worlds first bitcoin transaction. Other early supporters were Wei Dai, creator of bitcoin predecessor b money, and Nick Szabo, creator of bitcoin predecessor bit gold. In the early days, Nakamoto is estimated to have mined 1 million bitcoins. In 2. 01. 0, Nakamoto handed the network alert key and control of the Bitcoin Core code repository over to Gavin Andresen, who later became lead developer at the Bitcoin Foundation. Nakamoto subsequently disappeared from any involvement in bitcoin. Andresen stated he then sought to decentralize control, saying As soon as Satoshi stepped back and threw the project onto my shoulders, one of the first things I did was try to decentralize that. So, if I get hit by a bus, it would be clear that the project would go on. This left opportunity for controversy to develop over the future development path of bitcoin. The value of the first bitcoin transactions were negotiated by individuals on the bitcointalk forums with one notable transaction of 1. BTC used to indirectly purchase two pizzas delivered by Papa Johns. On 6 August 2. 01. Transactions were not properly verified before they were included in the blockchain, which let users bypass bitcoins economic restrictions and create an indefinite number of bitcoins. On 1. 5 August, the vulnerability was exploited over 1. Within hours, the transaction was spotted and erased from the transaction log after the bug was fixed and the network forked to an updated version of the bitcoin protocol. On 1 August 2. 01. Bitcoin Cash. Bitcoin Cash has a larger blocksize limit and had an identical blockchain at the time of fork. Design. Blockchain. For a broader coverage related to this topic, see Blockchain. Number of unspent transaction outputs. The blockchain is a public ledger that records bitcoin transactions. A novel solution accomplishes this without any trusted central authority the maintenance of the blockchain is performed by a network of communicating nodes running bitcoin software. Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications. Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes. The blockchain is a distributed database to achieve independent verification of the chain of ownership of any and every bitcoin amount, each network node stores its own copy of the blockchain. Approximately six times per hour, a new group of accepted transactions, a block, is created, added to the blockchain, and quickly published to all nodes. This allows bitcoin software to determine when a particular bitcoin amount has been spent, which is necessary in order to prevent double spending in an environment without central oversight. Whereas a conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions. Transactions. Number of bitcoin transactions per month logarithmic scale4. Transactions are defined using a Forth like scripting language. Transactions consist of one or more inputs and one or more outputs. When a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the blockchain. The use of multiple inputs corresponds to the use of multiple coins in a cash transaction.

Since transactions can have multiple outputs, users can send bitcoins to multiple recipients in one transaction. As in a cash transaction, the sum of inputs coins used to pay can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer. Any input satoshis not accounted for in the transaction outputs become the transaction fee. Transaction fees. Paying a transaction fee is optional. Miners can choose which transactions to process5. Fees are based on the storage size of the transaction generated, which in turn is dependent on the number of inputs used to create the transaction. Furthermore, priority is given to older unspent inputs. Ownership. Simplified chain of ownership. In reality, a transaction can have more than one input and more than one output. In the blockchain, bitcoins are registered to bitcoin addresses.
