Peer to peer (P2P) electronic cash is simply described as online money sent from one person to another without the need for a trusted third-party. As described in the original Bitcoin whitepaper by Satoshi Nakamoto, P2P cash makes use of digital signatures as part of the solution, but the main benefits are lost if a trusted third party is still required to prevent fraud. This makes P2P cash a trustless and safe way to transact without the need of intermediaries.

Comment puis-je confirmer Bitcoin sur Blockchain


Yes! In 2017, the Bitcoin project and its community split into two. Perhaps the least controversial way to refer to each side is simply by their respective ticker symbols, BTC and BCH. While exchanges commonly refer to BTC as simply “Bitcoin”, Bitcoin Cash, usually represented by the BCH ticker symbol, is considered by its supporters to be a legitimate continuation of the Bitcoin project, and the version with the best chance of creating a globally adopted peer-to-peer electronic cash system.

The would-be hard fork with an expanded block size limit was described by hardware manufacturer Bitmain in June 2017 as a "contingency plan" should the bitcoin community decide to fork; the first implementation of the software was proposed under the name Bitcoin ABC at a conference that month. In July 2017, the Bitcoin Cash name was proposed by mining pool ViaBTC. The change, called a fork, took effect on 1 August 2017. As a result, the bitcoin ledger called the blockchain and the cryptocurrency split in two.[16]

For the purposes of a thematic historical reference, most of the action supposedly takes place in Elba, New York. The city limit sign seen at the start of the film shows it has a population of 2,370, but the locations (such as a large shopping mall) are clearly in a much more populous town. Some identifiable settings are in more urbanized areas over 300 miles from the real Elba. It's acceptable for films to create a fictional version of a real town, but they should have changed the population sign to make it more consistent with the chosen locations. See more »

BCH is a cryptocurrency established as a result of the hard fork that took place to manage the scalability problem. Bitcoin Cash has a number of significant differences to Bitcoin: it is advertised as being faster and cheaper to use, the maximum block size is eight megabytes against one in previous Blockchain, and it has an emergency difficulty adjustment feature. Bitcoin Cash also uses 0-conf (or zero-conf) which allows for nearly instant transactions, meaning Bitcoin Cash transactions are almost always confirmed in the next block.

Bitcoin (BTC) is a consensus network that enables a new payment system and a completely digital currency. Powered by its users, it is a peer to peer payment network that requires no central authority to operate. On October 31st, 2008, an individual or group of individuals operating under the pseudonym "Satoshi Nakamoto" published the Bitcoin Whitepaper and described it as: "a purely peer-to-peer version of electronic cash, which would allow online payments to be sent directly from one party to another without going through a financial institution."

Bitcoin Cash was launched in August 2017, as a direct response to small block sizes on the Bitcoin code. 1MB block sizes were not meeting the demand of the growing community, so a group of dissatisfied crypto enthusiasts decided to create a ‘hard fork’ of the Bitcoin blockchain, with an increased 8MB block size. No one person currently takes credit for the token’s creation; rather it is attributed to a de-centralized group of developers.

Both Bitcoin as well as Bitcoin Cash use a proof-of-work algorithm to timestamp every new block. The proof of work algorithm used is the same in both cases. It can be described as a partial inversion of a hash function. Additionally, both Bitcoin and Bitcoin Cash target a new block to be generated every ten minutes on average. The time needed to calculate a new block is influenced by a parameter called the mining difficulty. If the total amount of mining power increases, an increase of the mining difficulty can keep the block time roughly constant. Vice versa, if the mining power decreases, a decrease of the mining difficulty can keep the block time roughly constant.[36]

The split originated from what was described as a "civil war" in two competing bitcoin cash camps.[18][29] The first camp, supported by entrepreneur Roger Ver and Jihan Wu of Bitmain, promoted the software entitled Bitcoin ABC (short for Adjustable Blocksize Cap) which would maintain the block size at 32MB.[29] The second camp led by Craig Steven Wright and billionaire Calvin Ayre put forth a competing software version Bitcoin SV, short for "Bitcoin Satoshi's Vision," that would increase the block size limit to 128MB.[26][29]
