Bitcoin Cash is a decentralized digital currency that was created in 2017 as a result of a hard fork from Bitcoin. The primary motivation behind the fork was to address Bitcoin's scalability issues, particularly the limitations in transaction speeds and high fees. Bitcoin Cash increases the block size limit from 1 MB to 8 MB (and later to 32 MB), allowing for more transactions to be processed in each block. This change aims to make Bitcoin Cash a more efficient medium of exchange, capable of handling a higher volume of transactions at lower costs compared to Bitcoin. Despite sharing the same foundational principles and much of the same codebase as Bitcoin, Bitcoin Cash operates as an entirely separate cryptocurrency with its own development roadmap and community.
