In  this case, both new and old nodes always work on the same chain, and the blocks generated by new nodes are considered legitimate by old nodes. Soft forks achieve forward compatibility, meaning that old software can accept data or code generated by new software. A well-known case of a soft fork is the creation of Bitcoin Cash (BCH), when a hard fork occurred in Bitcoin (BTC), and some nodes were not compatible with the new blocks, resulting in the formation of Bitcoin Cash."}]}],"pr":"803bf37282ede6f610ed3e060c5ba5d0de04c5d0432d1e81e076e7ba5234cb02"}
