Hard Fork (Blockchain)
In relation to blockchain technology, a hard fork (or hardfork) is a fundamental modification to a network’s protocol that renders previously invalid blocks and transactions valid, or vice versa. Every node or user must update to the most recent protocol version after a hard fork.
Developers or members of the cryptocurrency community who become unsatisfied with the features provided by the current blockchain implementations may start forks. They might potentially become a means of crowdsourcing capital for innovative technological endeavors or cryptocurrency offers.
