Confidential Consortium Framework

The Confidential Consortium Framework (CCF) is a free and open source blockchain infrastructure framework developed by Microsoft.
Originally called "Coco Framework", it was designed for building secure high-performance and high-availability applications that have a focus on multi-party compute and data.
The framework is used for developing distributed ledgers that can execute transactions with throughput and latency similar to those of a centralized database.
Overview.
The multi-party computation framework uses trusted execution environments (TEEs) such as Intel Software Guard Extensions (SGX).
Notable features include throughput and latency approaching database speeds, flexible confidentiality models, as well as network and service policy management through non-centralized governance. The framework uses deterministic consensus algorithms rather than proof of work or proof of stake.
The Confidential Consortium Framework was presented at FOSDEM 2020 in Brussels, Belgium. The CCF source code is licensed under Apache 2.0 License and available on GitHub. It runs on Linux and, according to Microsoft, it is primarily developed and tested on Ubuntu 18.04.
