According to BlockBeats, Mirror L2 has officially been renamed to Mirror Staking Protocol, with a focus on providing truly decentralized and secure BTC staking solutions for BTC L2 projects. The protocol aims to ensure 100% safe transfer of BTC to L2 and sharing within BTC L2. Mirror Staking Protocol utilizes the overlapping group multi-signature (MSG) algorithm, which is managed by hundreds or thousands of nodes, effectively balancing BTC staking rate, security, and decentralization. The algorithm has been published in top conference papers.

The MSG algorithm is also a practice of modular blockchain design, generating mBTC that is 1:1 pegged with BTC and compatible with EVM. It has also enabled the restaking mechanism. Mirror provides absolutely secure and decentralized BTC staking solutions for BTC L2 projects, with Mirror and BTC L2 projects in an upstream and downstream collaborative relationship. If BTC L2 projects are compared to electric vehicle manufacturers, Mirror provides the battery pack; if BTC L2 projects are large-scale models (LLM), Mirror is the computing power center.

Mirror plans to establish TVL and ecosystems with other BTC L2 projects through the 'Stake Once, Earn Twice' campaign in the future.
