Title:
Identity Chains
Authors: Andrew Egbert, Brad Chun, Thomas Otte
Abstract:In this short technical summary, the authors describe how the mathematical primitives of Ring Confidential Transactions may be used to provide anonymous identity authentication services in a similar manner to “Anonrep” but in a trustless (or permissioned), distributed manner, and with the additional security and resilience provided by a blockchain. The use of the mathematics in the RingCT paper additionally, and importantly, allows for combining different types of authentication in a seamless manner, in essence if the Bitcoin or Monero blockchain is a single “thread,” then the protocol here allows one to “weave” such threads together. The resulting protocol is dubbed an “Identity Chain” and provides anonymous authentication working in a lightweight and interoperable manner between any number of different service providers running different identity chains.
