Merlin Chain, a well-known Bitcoin-anchored L2 network for smart-contract capability, has announced a robust mainnet upgrade. The purpose of this exclusive mainnet upgrade is to improve Merlin Chain’s ZK verification. As Merlin Chain revealed in its official X post, the development will target the advancement of Zero-Knowledge (ZK) verification structure, validator nodes, and sequencer nodes. Hence, the goal of this move is to delve into a ZK verification infrastructure directly connected to Bitcoin Mainnet.

⚠️ Mainnet Upgrade Notice

Merlin Chain will undergo a comprehensive upgrade of the ZK infrastructure, Sequencer nodes, and internal validator nodes to explore a ZK verification architecture based on the Bitcoin Mainnet, laying the foundation for future improvements in network…

Merlin Chain Undergoes Exclusive Mainnet Upgrade to Bolster Scalability and Security

With the new mainnet upgrade, Merlin Chain is advancing its ZK verification mechanism. This will pave the way for future scalability as well as improved network security. Particularly, the upgrade is set to start on the 7th of November at 12:00 PM (UTC). Additionally, the estimated downtime of the upgrade is reportedly 24-48 hours.

As included in Merlin Chain’s latest mainnet upgrade, the platform intends to fortify its status as a cutting-edge Bitcoin L2 solution. For this purpose, it endeavors to enhance the underlying ZK infrastructure. In this respect, Zero-Knowledge proofs, which denote a cryptographic technique for transaction verification without the exposure of sensitive data, play key role in improving blockchain efficiency and privacy. Thus, with the integration of Bitcoin-based ZK validation model, the platform focuses on guaranteeing a relatively decentralized and secure consensus mechanism.

Network Operations to Restore Automatically Following New Upgrade

According to Merlin Chain, the mainnet upgrade will let users access historical transfers as well as account balances via its block explorer. The respective initiative ensures transparency along with seamless access to the data on-chain while optimizing backend components. Following the finalization of the upgrade, the platform will automatically be restored to normal operations.
