O que é Hard fork?
A rule change that loosens what is valid, so old nodes reject the new blocks and the chain splits unless everyone upgrades.
A hard fork requires universal adoption to avoid producing two chains. Where adoption is contested, the result is a permanent split with two assets, as happened in 2017.
Bitcoin has not hard-forked its consensus rules since its early years, which is a deliberate outcome of the norms around changing them.
