On Mar 27, 2020, the hCoV-19 Genome Analysis Platform ( https://db.cngb.org/virus/secure_evolution/visualization ) jointly developed by China National GeneBank and BGI Chain is officially launched and made available in China National GeneBank DataBase (CNGBdb). This analysis platform, which is the first in China based on blockchain and secure multi-party computing technology, allows users to collaborate with other researchers in data analysis and share the results without revealing their own data. It will further promote the real-time sharing of novel coronavirus genome data and related evolutionary analysis results, and provide strong support for epidemic prevention and control.
