Ark: Hard Fork
On November 28th 2018 our team and delegates will coordinate a switch to the new Core by installing the new Core on servers. This is a hardfork, which means that it will NOT be backwards compatible with the old code. All node operators will need to replace their old deprecated ARKNode code with ARKCore. Old nodes will NOT be able to communicate with new nodes, as they will be automatically banned. The upgrade process may result in small network downtimes — please bear with us.
The cryptocurrency mainnet operates according to certain rules. To improve network performance or correct errors, it is periodically made changes. A hard fork is changes that are not compatible with previous versions of programs that support the cryptocurrency network and in order to continue to mine cryptocurrency, miners need to update the software.
In some situations, as a result of a hard fork, a completely new cryptocurrency may appear, as happened with Bitcoin Cash.
