Integrating ZK Proofs with Bitcoin

Merlin Chain, a Layer 2 network designed to bring smart contract capabilities to Bitcoin, has completed a significant mainnet upgrade. The development focused on advancing its Zero-Knowledge (ZK) verification structure, validator nodes, and sequencer nodes to establish a ZK infrastructure connected directly to the Bitcoin mainnet.

This move aims to enhance both scalability and network security. By integrating a Bitcoin-based ZK validation model, Merlin Chain is working to build a more decentralized and secure consensus mechanism. Zero-Knowledge proofs, a cryptographic technique for verifying transactions without exposing sensitive data, are central to this effort, improving both blockchain efficiency and privacy.

Network Impact and User Access

The upgrade, which was initiated on November 7, involved an estimated downtime of 24 to 48 hours to optimize backend components. Following the finalization of the process, the platform’s normal operations were automatically restored.

Merlin Chain confirmed that users can continue to access historical transfers and account balances through its block explorer. This ensures that on-chain data remains transparent and accessible while the network benefits from the upgraded infrastructure.
