Bitcoin Cash

Bitcoin Cash is a cryptocurrency that was forked from the original Bitcoin blockchain in August 2017. Bitcoin Cash underwent a "hard fork", increasing the block size limit to 8 megabytes, allowing more transactions to occur in each new block. This has enabled Bitcoin Cash to claim superiority over Bitcoin in terms of performance and transaction costs.

Bitcoin Cash split from original Bitcoin caused turmoil in the cryptocurrency community - the so called "block wars". Supporters of Bitcoin Cash argued that increasing block size is necessary for higher transaction throughput, while defendants of original Bitcoin insisted that excessively large blocks can lead to centralization, as large block size requires extra processing power and memory that all Bitcoin node operators may not have available on their systems.

While majority of miners and node operators rejected the block size increase and continued to mine original blockchain, Bitcoin Cash did earn some supporters - especially among miners. It therefore continues to operate till this day, and, as of writing this article, remains the largest Bitcoin fork that carries the Bitcoin name.
