Comparison between multi-signature and MPC-based threshold signature (Threshold Signature Scheme TSS) - key management level

1. Multi-signature is based on scripts/smart contracts, so the first problem arises - adaptation to different chains.

2. Smart contracts are visible on the blockchain, so anyone can find out whether there are loopholes. It takes time to verify.

3. The levels of multi-signature are roughly the top smart contract (multi-signature effect layer), the middle signature algorithm (ECDSA elliptic curve, BLS, etc.), and the bottom blockchain
