Bitcoin Cash is a cryptocurrency.[4] In mid-2017, a group of developers wanting to increase bitcoin's block size limit prepared a code change. The change, called a hard fork, took effect on 1 August 2017. As a result, the bitcoin ledger called the blockchain and the cryptocurrency split in two.[5] At the time of the fork anyone owning bitcoin was also in possession of the same number of Bitcoin Cash units.[5]

Classification

Bitcoin Cash is a cryptocurrency[6] and a payment network.[7] In relation to bitcoin it is characterized variously as a spin-off,[6] a strand,[8] a product of a hard fork,[9] an offshoot,[10] a clone,[11] a second version[12] or an altcoin.[13]

History

Rising fees on the bitcoin network contributed to a push by some in the community to create a hard fork to increase the blocksize.[14] This push came to a head in July 2017 when some members of the Bitcoin community including Roger Ver felt that adopting BIP 91 without increasing the block-size limit favored people who wanted to treat Bitcoin as a digital investment rather than as a transactional currency.[15][16] This push by some to increase the block size met a resistance. Since its inception up to July 2017, bitcoin users had maintained a common set of rules for the cryptocurrency.[15] Eventually, a group of bitcoin activists,[12] investors, entrepreneurs, developers[15] and largely China based miners were unhappy with bitcoin's proposed SegWit improvement plans meant to increase capacity and pushed forward alternative plans for a split which created Bitcoin Cash.[11] The proposed split included a plan to increase the number of transactions its ledger can process by increasing the block size limit to eight megabytes.[15][16]

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.

In 2018 Bitcoin Core developer Cory Fields found a bug in the Bitcoin ABC software that would have allowed an attacker to create a block causing a chain split. Fields notified the development team about it and the bug was fixed.[17]

The research firm Chainanalysis noted that in May 2018, 17 largest payment processing services such as BitPay, Coinify, and GoCoin processed Bitcoin Cash payments worth of US$3.7 million, down from US$10.5 million processed in March.[18]

Bitcoin Cash is also referred to as Bcash.[19]

Trading

Bitcoin Cash trades on digital currency exchanges including Bitstamp,[20] Coinbase,[21] Gemini,[22] Kraken,[23] and ShapeShift using the Bitcoin Cash name and the BCH ticker symbol for the cryptocurrency. A few other exchanges use the BCC ticker symbol, though BCC is commonly used for Bitconnect. On 26 March 2018, OKEx removed all Bitcoin Cash trading pairs except for BCH/BTC, BCH/ETH and BCH/USDT due to "inadequate liquidity".[6] As of May 2018, daily transaction numbers for Bitcoin Cash are about one-tenth of those of bitcoin.[6]

By November 2017 the value of Bitcoin Cash, which had been as high as $900, had fallen to around $300, much of that due to people who had originally held Bitcoin selling off the Bitcoin Cash they received at the hard fork.[14] On December 20, 2017 it reached an intraday high of $4,355.62 and then fell 88% to $519.12 on August 23, 2018.[24]

Payment service providers

As of August 2018, Bitcoin Cash payments are supported by payment service providers such as BitPay, Coinify and GoCoin.[18]
