NOMOI is a decentralized delegation model where authority is represented as signed mandate edges in a verifiable graph. Instead of relying on global trust authorities, any entity may act as a trust root by issuing signed delegation mandates. These mandates form bounded delegation graphs, where each edge defines constrained authority transfer (scope, time, and delegation rights). Mandates are published on a content-addressed storage layer (e.g. IPFS) and can be independently retrieved and verified using only the issuer’s public key. Authorization is determined by evaluating reachability within this delegation graph under constraint composition rules, without requiring a central authority or global registry. Verification is fully local given a subset of the graph, while global consistency is not required.
