[2021:158] BLOCKCHAIN WORD OF THE DAY #01 : HARDFORK
Hardfork (or hard fork) is a state where there are two versions of a blockchain protocol are available and running. And this can happen to all blockchain. When a hard fork occurs, it is like a double-edged fork, one edge follows the old protocol while the other follows the new protocol. All nodes must agree on a version of the blockchain so that the blockchain can go back to its normal state.
A hardfork, as a radical change to the blockchain protocol, can occur when the blockchain decides to validate a previously invalid transaction or block, or vice versa (cancel the validity of a validated transaction or block).
Hardforks have similarities with upgrading the operating system on a home computer or laptop. If the blockchain (eg STEEM) is the operating system, then the hardfork is an OS upgrade or system restore. In this parable, STEEM is equivalent to, for example, Microsoft Windows, and a hard fork is when Windows is upgraded to the latest version or a system restore is performed.
Steem On. Thanks For Stopping By.
