Hydra to Undergo Hard Fork on March 18th
Hydra will undergo a mandatory mainnet hard fork on March 18th. This update requires all users to upgrade their clients to version 0.20.19. Older versions of the client will become obsolete after the hard fork, which is scheduled to occur at block 1,849,150.
What is a hardfork?
The cryptocurrency mainnet operates according to certain rules. To improve network performance or correct errors, changes are periodically introduced into it. A hard fork represents changes that are not compatible with previous versions of software supporting the cryptocurrency network. In order to continue to mine the cryptocurrency, miners need to update the software.
In some cases, as a result of a hard fork, a completely new cryptocurrency may appear, as happened with Bitcoin Cash and EthereumPoW.
