Circial is putting assurance into shared data and machine learning models, to provide future-proof validation that what you are using is what it claims to be. Building on ongoing PhD research, Circial is using the latest decentralised technologies to develop ensembleID, a crypotgraphically secure and private platform that can offer on-going verification and validation of the data and the people building AI systems. By providing a simple way to maintain and demonstrate trust in shared open source or commercial solutions, we seek to unlock the benefits of machine learning and big data for those who don't have the time or skills to build their own systems, while providing a new market for asset creators and vendors.
