Merlin Chain to Undergo Hard Fork
On June 26, 2025, from 02:00 to 14:00 UTC, Merlin Chain conducted a major mainnet upgrade, transitioning from Fork 9 to Fork 12. The upgrade significantly improves performance, reliability, and infrastructure. Key improvements include a new zkEVM-based sequencer architecture for optimized transaction management and a migration to CDK-Erigon RPC for smoother on-chain operations and enhanced node stability.
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.
