noun | hahrd fawrk
A hard fork is like a divorce on the blockchain - it's when a cryptocurrency splits into two separate chains, usually because of some irreconcilable differences between the developers and the community. It's like a custody battle over the coins, and everyone has to pick a side.
Example
"When Bitcoin Cash hard forked from Bitcoin, it was like watching your parents get divorced - messy, confusing, and everyone ended up poorer in the end."
"I'm thinking about hard forking my shitcoin to create a new version with an even bigger premine. Gotta keep those VCs on their toes, ya know?"
