Zilliqa to Activate Mainnet Hard Fork on October 22
Zilliqa is preparing for a major network upgrade under Zilliqa 2.0. The hard fork is scheduled at block 11,998,800 on October 22, 2025, following its earlier activation on the testnet at block 14,997,600 on September 19, 2025. The update introduces improvements in security, stability, and efficiency, including stricter validation, faster state migration, and optimized backend performance. Validators are advised to update nodes before the fork to avoid disruptions.
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.
