 FISCO BCOS is the first safe and controllable enterprise-level financial consortium blockchain platform open source by domestic enterprises. It is jointly created by the FISCO open source working group and officially launched in December 2017.
 
-The community links multiple parties with open source. At present, more than 500 enterprises and institutions and more than 10,000 community members have joined to build and co-governance, and developed into the largest and most active domestic consortium blockchain platform ecosystem. The underlying platform is highly available and easy to use after extensive application and practice. Hundreds of application projects are developed based on the FISCO BCOS underlying platform, and over 60 have been steadily operating in the production environment, covering cultural copyright, judicial services, government services, Internet of Things, finance, smart communities and other fields.

 ```eval_rst
 .. note::
     FISCO BCOS takes the actual needs of the consortium blockchain as a starting point, taking into account performance, security, maintainability, ease of use, and scalability, and supports multiple SDK, and provides visual middleware tools, greatly reducing the time to build chains, develop and deploy applications. In addition, FISCO BCOS passed the two evaluations of the Trusted Blockchain evaluation function and performance of the Information Communication Institute, and the single-chain TPS can reach 20,000.
