Bitcoin Cash is a peer-to-peer electronic cash system that allows participants to digitally transfer units of bitcoin cash without a trusted intermediary. Bitcoin Cash is a result of a chain split from the Bitcoin Core protocol, as part of an upgrade increasing the block size limit from 1MB to 8MB (and later to 32MB). Bitcoin Cash also notably does not support Segregated Witness (SegWit), a code adjustment for Bitcoin transactions that separates digital signatures from the block header. Like Bitcoin, Bitcoin Cash has a supply cap of 21 million bitcoin cash and relies on Nakamoto consensus, or consensus implied by the longest blockchain with the most accumulated computational effort.
During a fork of the BCH chain in November 2018, Bitcoin Cash Satoshi's Vision and BitcoinABC were created. Since then, many exchanges have returned to naming the BitcoinABC chain simply "Bitcoin Cash (BCH)". Over time, the Bitcoin Cash SV chain began to be referred to more commonly as just Bitcoin SV, helping to avoid conflict in naming.
Some exchanges refer to Bitcoin Cash with the ticker "BAB" (Binance, Bitfinex, Poloniex) or "BCC" (BitBay, Bittrex). Cryptowatch refers to these tokens under the BCH ticker.
