level of work it's going to take to validate the hash is why the Bitcoin network consumes a lot computational power and Electricity.

By way of example, Ethereum was really hard forked in 2016 to "make full" the investors within the DAO, which had been hacked by exploiting a vulnerability in its code. In this case, the fork resulted in a split creating Ethereum and Ethereum Typical chains.
