Although Bitcoin served as a blueprint for the rest of early altcoins and is still widely considered to be the standard of cryptocurrency, it did not come without flaws and limitations. To fix those, developers came up with original code, soft-forked the Bitcoin codebase, or hard-forked the blockchain. This is how Bitcoin Cash came to be in 2017 when a community could not reach a consensus on whether to lift or leave the cap on block size.
The debate did not stop at raising the limit to 2 MB, and the part of the community that insisted on the removal of the cap forked the Bitcoin Cash blockchain. The new cryptocurrency was named Bitcoin Satoshi Vision, referring to the name of the Bitcoin white paper — "peer-to-peer electronic cash".
After removing the limit on the number of transactions in a block altogether, the Bitcoin SV blockchain became a platform with significantly better scalability than the original protocol. Since the community considers the protocol of Bitcoin to be a done deal, they are developing an ecosystem of applications and the software without amending the protocol coded by Satoshi Nakamoto.
