Ant blockchain Yan Yan: The bottleneck of blockchain performance is efficient execution of contracts, not consensus algorithms.

Babbitt reported that on June 1, the China Blockchain Technology and Application Summit Forum hosted by the Chinese Computer Society (CCF) was held in Nanjing. Yan Wei, technical director of the ant blockchain and senior technical expert of the blockchain laboratory of the Alibaba Institute, said in a speech entitled "Exploration of the core technology in the commercialization of ant blockchains", the bottleneck of blockchain performance is not It lies in the consensus algorithm, but in the efficient execution of the contract, which lies in the IO (ie the stored input and output). In order to break through the IO bottleneck, the ant blockchain has developed a new storage architecture. The advantages of this architecture are: First, an innovative data model to make blockchain contract application development more natural; Second, to improve storage efficiency by 6-8 times; Third, distributed storage architecture with horizontal and vertical expansion capabilities; It is a layered processing of hot and cold data, and storage costs are more optimized.
