According to official sources on March 13th, Mirror L2 has officially been renamed to Mirror Staking Protocol. The protocol will now focus more on providing a truly decentralized and secure BTC staking solution for BTC L2 projects, ensuring that BTC is 100% secure when transferred to L2 and shared on BTC L2. Mirror Staking Protocol uses the Overlapping Group Multisignature (MSG) algorithm, which is managed by hundreds or thousands of nodes, effectively balancing BTC staking rates, security, and decentralization. This algorithm has been published in top conference papers. This algorithm is also a practice of modular blockchain design, generating mBTC anchored 1:1 with BTC that is compatible with EVM and has been empowered with restaking mechanisms. Mirror provides an absolutely secure and decentralized BTC staking solution for BTC L2 projects, and Mirror and BTC L2 projects are in upstream and downstream cooperation. If BTC L2 projects are compared to electric vehicle manufacturers, Mirror provides the battery pack; if BTC L2 projects are large models (LLM), Mirror is the computing center. Mirror's future plans include establishing TVL and ecosystems with other BTC L2 projects through the "Stake Once, Earn Twice" campaign.
