The Bitcoin scalability debate led to the cryptocurrency split on August 1, 2017. A chain coming out of the split and setting its block size limit to eight megabytes to increase the number of transactions its ledger can process is called Bitcoin Cash (BCH). The rule change increasing the bitcoin block size limit is classified as a hard fork.

The bitcoin scalability problem is a consequence of the fact that blocks in the blockchain are limited to one megabyte in size. Bitcoin miner fees for processing bitcoin transactions rose to above $25 per transaction in December 2017, making small payments uneconomical.
Bitcoin’s blocks include the transactions on the bitcoin network. In contrast to Visa’s peak of 24,000 transactions per second, the bitcoin network’s theoretical maximum capacity with the 1MB block size limit sits between 3.3 to 7 transactions per second. Various scaling proposals, some activated, are described below.
