$BCH
Bitcoin Cash is a P2P electronic cash system that aims to become sound global money with fast payments, micro fees, privacy and larger block size. As a permissionless, decentralized cryptocurrency, Bitcoin Cash requires no trusted third parties.
Bitcoin Cash was created as an alternative to the first and most valuable cryptocurrency — BTC. In 2017, BCH developers modified the BTC code, releasing their software version and a full-fledged competitive product, which split Bitcoin into two blockchains: Bitcoin and Bitcoin Cash. Bitcoin Cash is a result of a hard fork in the blockchain due to differences in the community over Bitcoin scaling and the SegWit upgrade. Moreover, another hard fork, which divided Bitcoin Cash into two parts, Bitcoin ABC and Bitcoin SV, took place in the fall of 2018.
The scaling debate involved two sides: small block supporters opposed increasing block size as it could lead to blockchain centralization and vulnerability by making it harder to host full nodes. Large block supporters, however, advocated for a faster solution, concerned that rising transaction fees could hinder growth.
Bitcoin Cash was considered by some supporters to be the legitimate continuation of Satoshi Nakamoto’s vision of Bitcoin as a peer-to-peer electronic cash. All Bitcoin holders at the time of the fork (block 478,558) automatically became owners of Bitcoin Cash.
From a technical perspective, Bitcoin Cash is similar to the Bitcoin algorithm. Namely: both projects have a hard cap of 21 million coins and also use POW (Proof Of Work) consensus framework and nodes to verify transactions.
As of 2023, Bitcoin Cash has a block size of 32MB, compared to Bitcoin’s block size of 1MB.
