A large number of blockchain-based identity management approaches are being explored, implemented, and commercialized. This is a new field, and the features, security, and privacy of these proposed systems are often unclear. While many of the approaches hold great promise, most projects rely on the prerequisite of using a blockchain platform that is reliable, secure, scalable, and, sometimes, publicly accessible. Thus, blockchain-based identity management systems are an emerging area that should be watched and carefully evaluated as a potential, but not guaranteed, breakthrough for digital identity and data ownership.
