Bitcoin Cash (BCH) is a cryptocurrency that was created as a result of a hard fork from Bitcoin (BTC) in August 2017. The hard fork occurred due to disagreements within the Bitcoin community about the best way to scale the Bitcoin network and process transactions more efficiently.

Bitcoin Cash aimed to address the scalability issue by increasing the block size limit of Bitcoin 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.

Bitcoin Cash shares many similarities with Bitcoin, including its decentralized nature and the use of a proof-of-work consensus mechanism. It also has a maximum supply limit of 21 million coins, just like Bitcoin.

However, Bitcoin Cash has some key differences from Bitcoin. Besides the larger block size, Bitcoin Cash also implemented a new difficulty adjustment algorithm (DAA) to ensure a more stable mining ecosystem. It sought to promote widespread adoption as a digital currency for everyday transactions by offering faster confirmation times and lower fees.

Since its creation, Bitcoin Cash has gone through several protocol upgrades, including additional increases in the block size limit and the implementation of features such as Schnorr signatures and the Simple Ledger Protocol (SLP) for token creation on the BCH blockchain.

It's worth noting that Bitcoin Cash has faced its share of controversy and has a divided community. There are different factions within the Bitcoin Cash ecosystem that have differing visions and approaches for the cryptocurrency's development.

As with any cryptocurrency, the value of Bitcoin Cash is subject to market fluctuations and can be influenced by various factors such as market demand, adoption, regulatory developments, and overall market sentiment.
