Bitcoin Cash es un "hard fork" de la criptomoneda bitcoin. El "fork" tomó lugar el 1 de agosto de 2017.[1]​[2]​[3]​

Historia[editar]

El 20 de julio del 2017, los mineros del bitcoin votaron, 97% en favor al "Bitcoin Improvement Proposal (BIP) 91". La propuesta, hecha por el ingeniero James Hilliard, fue activar el "Segregated Witness" (SegWit).[4]​[5]​[6]​

Algunos miembros de la comunidad del bitcoin creyeron que implementar el BIP 91 sin incrementar el limite en el tamaño del bloque, únicamente retrasaría la confrontación del problema y que esto favorecía a la gente que quería usar el bitcoin como una inversión digital en vez de una moneda transaccional.[2]​[3]​

Ellos anunciaron la complementación del Bitcoin Cash como un "hard fork" el 1 de agosto. Este

They announced implementation of Bitcoin Cash as a hard fork for August 1. It inherited the transaction history of the bitcoin currency on that date, but all later transactions were separate. Block 478558 was the last common block and thus the first Bitcoin Cash block was 478559.[7]​ Bitcoin Cash wallet started to reject BTC block and BTC transactions since 13:20 UTC, Aug 1st 2017 because it used a timer to initiate a fork. It implements a block size increase to 8 MB. Bitcoin Cash started futures trading at 0.5 BTC on July 23, but dropped to 0.1 BTC by July 30. Market cap appeared since 23:15 UTC, August 1, 2017[3]​[8]​

On August 9th, it was 30% more profitable to mine on the original chain.[9]​ Even though the fork allows for a higher block size, block generation was so sporadic that the original chain was 920 MB bigger than the chain of the fork, as of August 9th.[9]​

Response from exchanges[editar]

Coinbase[editar]

Coinbase initially announced that it would not support Bitcoin Cash.[10]​[11]​[12]​[13]​ This led to consumer backlash and speculation about a class action lawsuit from consumers.[14]​[15]​ On August 3, Coinbase announced that it would start supporting Bitcoin Cash transactions by January 1, 2018, and that users who had any amount of bitcoin at the time of the fork were credited an equal amount of Bitcoin Cash though they could start transacting in it only once Coinbase was ready to transact.[16]​[17]​[18]​

Other exchanges[editar]

China-based ViaBTC began allowing trading in Bitcoin Cash before it went live.[10]​ Kraken[19]​ and Bitfinex[20]​ announced that they would support Bitcoin Cash.[21]​[12]​ On August 4, 2017, Bitfinex officially opened up Bitcoin Cash deposits and withdrawals.[22]​

BitMEX,[23]​ Exodus, and Bitstamp announced that they would not support Bitcoin Cash.[12]​[24]​[25]​

Altcoin exchange Poloniex had not announced a decision as of July 2017, but said that they were making a decision keeping the security of users' bitcoins in mind.[26]​[24]​ In mid-August Poloniex began trading Bitcoin Cash.[27]​

Supporters[editar]

Supporters of Bitcoin Cash (both the idea of increasing the block size and the split of the cryptocurrency) include Tokyo-based investor Roger Ver.[2]​
