When designing a distributed system by analogy, metadata nodes need strong consistency, and data nodes only need final consistency
Analogous to big data systems, batch processing of historical data processing, streaming processing of real-time data processing.
It is roughly designed as follows: 1. Blockchain-based event management system: the main chain stores events, builds a rule engine at the side chain contract level to process complex events.
Call side chains such as loom or directly use contracts calculated off-chain.
It is expected to implement a smart contract rule engine that can process events in real time.
