verifiable self-managed identities

What we're BUIDLING

Caisson is a developing a system that allows for individuals to take ownership of facts about their identity established by a third party, and share these facts in a verifiable way with interested parties. We're aiming to make identity attributes reusable without the need to go through the arduous process of being re-verified every time they are accessed. Instead, the individual themselves can be the porter of the key facts about themselves they need to transact, and the previously established integrity of these facts can be reverified and relied upon repeatedly.

The concept of a self-managed, proven identity is not new. However, the advent of distributed public ledgers (blockchains), and the accompanying storage and computing power possible on top of them, means that we now have a new and novel approach to the thorniest problems that have plagued past solutions - publication and discovery. Our use of the Ethereum blockchain will afford users an easy-to-access, tamper-proof, bias-free place to publish and retrieve the crucial components necessary for securely sharing information about themselves. With it, we're building an open and distributed infrastructure that will form the basis of verifiable self-managed identities.
