From the design intention, EMIT has the following predecessors：
1、The security of the decentralized scheme is not significantly weaker than in the cross-chain system.
2、It is feasible and available in practice.
3、It has a wide range of applicability and can provide cross-chain function for most mainstream blockchains.
4、Cross-chain operation is possible between fungible tokens (FTs) and non-fungible token (NFT) assets.
5、The solution can eventually migrate to the cross-chain framework of the EMIT Core Protocol network.
6、Provides privacy protection to FT and NFT owners and related parties.
7、Another FT asset used as consensus maintenance is not used for the underlying system for now.
8、The design is simple and intuitive, and easy to implement and maintain.
