Nerve is a decentralized digital asset service network, which is based on the NULS Microservices framework. It is a set of blockchain cross chain interaction protocols developed and built using the NULS chain building tool ChainBox. Intended to break the current situation of blockchain value silos, establish a cross chain and interconnected asset exchange network, and provide all necessary underlying support for the Defi application ecosystem. Enable digital asset holders to enjoy truly secure, free, and transparent Defi application services.Through the Nerve cross chain interaction protocol, with minimal development through standard interfaces, blockchains with different structures can be transformed into a set of universal asset types that can be recognized by cross chain modules in the NULS ecosystem. To facilitate asset interaction within and outside the NULS ecosystem, while also providing rich Defi usage scenarios for mainstream digital assets such as BTC and ETH....
