The article deeply explores how Merlin Chain ensures the security of its US$3.5 billion funds. Merlin Chain adopts a multi-token staking Oracle node system to achieve decentralization and resistance to single points of failure. By sharing the data availability layer (DA layer) with Celestia, the openness, transparency and on-chain storage of data are ensured. In addition, Merlin Chain inherits the security of Bitcoin and submits the L2 data to the L1 Bitcoin for verification through the Taproot solution. To further enhance security, Merlin Chain has partnered with Cobo to use the MPC wallet solution to manage assets and ensure the safety of funds. At the same time, Merlin Chain has also joined forces with several security companies to establish the Merlin Security Committee and supports on-chain monitoring through third-party platforms to jointly ensure the safety of funds.
