Why do blockchains fork?
Forks occur when the software of different miners become misaligned. It’s up to miners to decide which blockchain to continue using. If there isn’t a unanimous decision, then this can result in the creation of two versions of the blockchain. There can be periods of increased price volatility around such events.
Why might a blockchain fork?
