Bitcoin Cash (BCH) is a cryptocurrency that was created as a result of a hard fork from the original Bitcoin (BTC) blockchain. The fork occurred on August 1, 2017, with the goal of addressing some of the scalability issues faced by Bitcoin.

Bitcoin Cash aimed to increase the block size limit from 1MB to 8MB, allowing for more transactions to be processed in each block. This larger block size was intended to enable faster and cheaper transactions compared to Bitcoin. Additionally, Bitcoin Cash implemented a new difficulty adjustment algorithm to ensure a more stable mining ecosystem.

The key proponents of Bitcoin Cash believed that by increasing the block size, it would allow more users to adopt and use the cryptocurrency for everyday transactions, making it more practical as a digital cash system. They wanted to prioritize the usability and scalability of the blockchain.

Bitcoin Cash shares a common transaction history with Bitcoin up until the fork point, meaning that anyone who held Bitcoin at the time of the fork received an equal amount of Bitcoin Cash. After the fork, Bitcoin and Bitcoin Cash became separate, independent cryptocurrencies with their own distinct networks and blockchains.

Since its creation, Bitcoin Cash has had its share of supporters and detractors within the cryptocurrency community. Some people appreciate its larger block size and see it as a solution for scaling Bitcoin, while others argue that increasing the block size compromises the decentralization and security of the network.
