What is Hardfork

1 – What is Hardfork?

Hardfork or hard fork is a term referred to in blockchain technology. This term describes a protocol change in the network that causes old blocks and transactions to be invalidated.

When a project hard forks a coin, the nodes or users of that network must upgrade to the latest version of the protocol software.

In this case, a group of nodes continues to use the old protocol software in parallel with the nodes that have updated the new protocol software. At this point, the split will occur into 2 different chains.

You can understand in the simplest way a hard fork is the creation of a different version of the coin that overcomes the previous disadvantages of the old version of the coin. The creation of a new version is still based on the old version.
