Each computer in the blockchain network has its own copy of the blockchain, which means that there are thousands, or in the case of Bitcoin, millions of copies of the same blockchain. ( edit history ) A hard fork is a rule change such that the software validating according to the old rules will see the blocks produced according to the new rules as invalid. Retrieved Put in the simplest terms, the quest for decentralised trust has quickly become an environmental disaster.
