Fund security is undoubtedly the key to the survival of the public chain. For Merlin Chain, which has a TVL of 3.5 billion US dollars, ensuring fund security is the top priority. Merlin Chain protects this huge amount of funds through a series of carefully designed security mechanisms to ensure the security and stability of user assets. 1. Merlin Chain has added layers of code in the architectural design, ensuring the security and flexibility of the network through decentralized Oracle and diversified asset support. The multi-token staking Oracle node system makes power decentralized, data transparent, and effectively resists single point failures. At the same time, supporting the staking of multiple mainstream assets not only improves the flexibility of the network, but also enhances its risk resistance. 2. Merlin Chain shares DA layer security with Celestia to ensure the verifiable release of block data and the transparent credibility of the network. This measure effectively prevents data withholding attacks and ensures that users can withdraw smoothly. In addition, Merlin Chain also inherits the security of Bitcoin by verifying the first layer. Its solution based on Taproot's aggregated zero-knowledge proof and Rollup data writing to the Bitcoin mainnet makes the security of the second-layer data strongly guaranteed by the first-layer network. Any problems on the second layer, whether it is fraud or error, will be discovered and prevented by the first layer. 3. In terms of asset management, Merlin Chain adopts Cobo's MPC wallet solution to achieve institutional-level security. Advanced measures such as isolation of hot and cold wallets and implementation of threshold signature schemes by MPC technology ensure the safe non-custodial nature of cross-chain/locked funds. The security risk control strategy jointly implemented by both parties effectively prevents the risks that may be brought about by any party acting alone. Merlin Chain provides solid protection for 3.5 billion funds through multiple security mechanisms such as architectural design, data layer shared security, first-layer verification and institutional-level asset management. These measures not only ensure the security of funds, but also enhance Merlin Chain's competitiveness in the fiercely competitive blockchain field. For users, choosing Merlin Chain means choosing financial security and stability. It is one of the trustworthy second-layer networks#Merlinchain
