The hard fork is upcoming!

In connection to blockchain technology, a hard fork is a change in the protocol which influences on transactions and blocks. It requires users and nodes to update the newest version of the software’s protocol.

The hard fork is upcoming! – how does it work?

Put another way, it is is a new section of a blockchain version. The previous node’s version will be no longer valid. It creates some kind of fork in the blockchain. One of two paths follows the new blockchain, the second – along the old one.

This activity involves splitting the path of a blockchain by invalidating transactions confirmed by nodes that have not been upgraded to the new version of the protocol software. Users of the old blockchain quickly realize that its version is outdated and needs an update. Moreover, it allows reducing security threats in older versions of the software, to develop functionality and rollback transactions.

Differences between a hard fork and soft fork

Obviously, a hard fork and a soft fork are a very similar process in which cryptocurrency code changes. In the case of the soft fork, only one blockchain is valid when users accept the changes while a hard fork relates with two blockchains. All users and programmers decide to carry out a hard fork for security reasons, although soft fork could also do the job. Furthermore, a hard fork associates with the release of high computing power, it is much safer than a soft fork.

We are so happy that the hard fork is upcoming soon!
