【Abstract】This paper presents a democratic nature inspired evolvable chain (shorten as EVONChain), a scalable and decentralized public blockchain architecture with high throughput and fast confirmation. EVONChain decouples the function of a full blockchain node into two processes of consensus that are completed separately in two connected networks, with a small number of high-performance cloud nodes in the inner network responsible for collecting and validating transactions, packaging blocks, as well as implementing a consistent replication, and a huge number of low-performance user nodes, connected through the Mobile Edge Computing (MEC) in the outer network, are responsible for the Proof of Intelligence (PoI) work, a novel Proof of Work (PoW) mechanism that resists Application-Specific Integrated Circuit (ASIC) computing and enables "one-CPU-one-vote". To make full use of inner network bandwidth, the graph-chain consensus protocol with high bandwidth utilization called ORIC was deployed to EVONChain. The relationship between the inner and outer networks is enhanced through the bi-tiered incentive mechanism. We developed an EVONChain simulator and evaluated EVONChain on it with up to 5000 nodes. Under the inner network bandwidth of 1.5Gbps, EVONChian can achieve a throughput of close to 375,000 transactions per second, with a block interval of 10s and an orphaned block rate of less than 7%. Simulation results show that EVONChain can drastically increase the performance scalability of practical high-frequency applications, and greatly decrease the confirmation time to a minute level.
