Abstract

We present Solidus, a decentralized protocol for issuing, presenting, and verifying credentials. The design combines W3C Verifiable Credentials, BBS+ signatures, and a HotStuff-based BFT consensus among staked validators. The paper covers the protocol stack, validator economics, threat model, and performance benchmarks on testnet.
