The 2020 International Blockchain Academic Conference, hosted by BUPT(Beijing University of Posts and Telecommunications), was held from October 10 to October 11, 2020. This conference aims to provide in-depth communications and discussions on blockchain technology fields such as blockchain applications and services, blockchain scalabilities, blockchain securities and crypto algorithms. Dr. Qi Zhou, the founder and CEO of QuarkChain, was invited to participate in the conference remotely and gave a live broadcast on the topic of “High-performance Blockchain Infrastructure Database Optimization”.

At his presentation, Dr. Zhou shared an in-depth and detailed introduction on the blockchain infrastructure database optimization: One hot topic in the blockchain area is to improve the single-chain performance in terms of transactions per second (TPS). Most of the ongoing projects are focusing on improving the consensus so that the network can reach a consensus or finalize a block in a couple of seconds. Some of the projects claim that, under their test environments, their networks can reach thousands of TPS.

However, most of these tests use a small state, i.e., a small number of accounts in the blockchain database, while the most popular blockchain such as Ethereum has more than 100M accounts nowadays. The more the accounts are in the database, the lower the performance of the network can be. Dr. Zhou use the production data from Ethereum and perform a test to show that, even without the cost of consensus, with 100M accounts, it is almost impossible to achieve 1000 TPS stably using a traditional ledger model such as Patrica Merkle Tree.

To address the performance bottleneck of the database, Dr. Zhou leads the QuarkChain Tech Team and proposes a FastDB ledger model. Using Ethereum production data, Dr. Zhou demonstrates that, without the cost of consensus, FastDB is able to achieve more than 10000+ TPS without sacrificing security. The QuarkChain mainnet is the platform for theoretical verification and landing of these technologies.

The 2020 International Blockchain Academic Conference is a series of academic conferences celebrating the 65th anniversary of Beijing University of Posts and Telecommunications. The conference attracted Chinese and foreign researchers and participants in the blockchain field to attend, including JD, Hyperledger, Huobi, Baidu, and other corporations and academics. QuarkChain got the opportunity to show the infrastructure design to well-known digital information scientists and blockchain experts, and gained more recognition from researchers and experts.
