The Confidential Consortium Framework (CCF) is a free and open source blockchain infrastructure framework developed by Microsoft.[2] It was originally called Coco Framework. The framework is used for developing distributed ledgers that can execute transactions with throughput and latency similar to those of a centralized database.


The multi-party computation framework uses trusted execution environments (TEEs) such as Intel Software Guard Extensions (SGX).[2]

The Confidential Consortium Framework was presented at FOSDEM 2020 in Brussels, Belgium.[3] The CCF source code is licensed under Apache 2.0 License and available on GitHub.[4] It runs on Linux and, according to Microsoft, it is primarily developed and tested on Ubuntu 18.04.[5]
