A hard fork introduces an incompatible change that is fundamentally unrelated to the protocol of a blockchain network.

This means that the new version of the blockchain cannot validate blocks created by the older version, and vice versa. Splitting the blockchain results in two distinct chains: the original chain and the forked chain.

In hard forks, the community modifies code to such an extent that it becomes incompatible with older versions. These modifications include updates, enhancements and new features. When new blocks or changes are made, a new ledger is created for all nodes.

This digital ledger makes it harder to manipulate the Blockchain, which can be irreversible.

Hard forks caused the blockchain network to split into two. One cryptocurrency adheres to new regulations while the other adheres outdated standards.

It is up to the individual's judgment. The user can choose to use the newest cryptocurrency or their old one. The latest cryptocurrency must be updated on all computer nodes to ensure that it is accepted by the blockchain.

Hard forks are often used by developers to create new coins and initiatives. Hard forks can be used to fix bugs, corrupt files or conflicts as well as improve security or services.
