Bitcoin Cash (BCH) is a peer-to-peer cryptocurrency that was created in 2017 as a result of a hard fork from the original Bitcoin (BTC) network. It was founded by a group of influential figures in the cryptocurrency community, including Roger Ver and Jihan Wu, who believed in the need for larger block sizes to accommodate more transactions and lower fees, aiming to improve Bitcoin's scalability and usability as digital cash.

The core logic of Bitcoin Cash revolves around its larger block size (initially 8MB, later increased to 32MB) compared to Bitcoin's 1MB blocks. This allows BCH to process more transactions per block, making it a faster and more affordable cryptocurrency for day-to-day transactions. It also follows the same decentralized and trustless principles as Bitcoin, using a proof-of-work consensus mechanism to validate and record transactions on a public ledger known as the blockchain.

Key milestones and events in BCH's development include the successful hard fork from Bitcoin on August 1, 2017, which marked its official launch. Subsequent upgrades like the November 2018 "Bitcoin Cash upgrade" aimed at further increasing block sizes, while the November 2020 "Bitcoin Cash network upgrade" focused on improving network security.

In recent years, Bitcoin Cash has witnessed ongoing development efforts to enhance its scalability, security, and usability. Developers have been working on projects like "Schnorr signatures" and "CashFusion" for enhanced privacy and "Avalanche" for quicker consensus. However, BCH has faced its share of challenges, including internal disputes and competition from other cryptocurrencies.

While Bitcoin Cash continues to be used for various transactions and payments, its adoption and progress are closely watched within the larger cryptocurrency ecosystem, with the aim of achieving its founders' vision of a widely accepted digital cash system.
