The Confidential Consortium Framework (CCF) is a free and open source blockchain infrastructure framework developed by Microsoft.[2][3] 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.[4] 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 (TTEs)[5] such as Intel Software Guard Extensions (SGX).[4][2]
Notable features include throughput and latency approaching database speeds, flexible confidentiality models, as well as network and service policy management through non-centralized governance.[4] The framework uses deterministic consensus algorithms rather than proof of work or proof of stake.[6]
The Confidential Consortium Framework was presented at FOSDEM 2020 in Brussels, Belgium.[7] The CCF source code is licensed under Apache 2.0 License and available on GitHub.[8] It runs on Linux and, according to Microsoft, it is primarily developed and tested on Ubuntu 18.04.[9]
