What is Source-Code Fork?

A source-code fork is a type of hard fork that results when software engineers take the original source code from an existing blockchain network to create a new network. Like all hard forks, source-code forks can make previously invalid blocks and transactions on a blockchain network valid, and require all nodes from the previous network to upgrade to the latest version of the software protocol. Further, source-code forks, like all hard forks, are not backwards-compatible, meaning they cannot be reversed to their previous state.
