Categories

Standards & Specifications53The open specifications Solidus is assembled from: W3C DIDs and Verifiable Credentials, the IETF's JOSE and OAuth families, DIF's interop protocols. The largest section here, and the one with the most running code behind it.
Identity & Verification48The vocabulary of proving who someone is: KYC, IDV, AML, liveness, portability. The language your compliance team and your vendors already speak, defined without the sales pitch.
Consensus & Chain23How the Solidus chain agrees on state: HotStuff BFT, validators, finality, slashing. Every mechanism here has a published paper behind it, and every entry names it.
Cryptography23The mathematics underneath selective disclosure: BBS+, BLS, zero-knowledge proofs, Merkle trees. What each primitive actually guarantees, and what it does not.
AI Agents & Machine Identity19Identity for software that acts on its own: ERC-8004 agent passports, workload identity, verifiable off-chain compute. The newest vocabulary in the book, and the fastest moving.
Unit Economics & Cost10What verification costs, what reuse saves, and who carries the liability when a check is wrong. Every figure here is a model you can re-run with your own numbers.
EU Regulation10eIDAS 2.0, the EUDI Wallet, the Architecture Reference Framework, GDPR, MiCA. What each one obliges you to do, and when the deadline actually falls.
Türkiye Regulation10MASAK, KVKK, TCKN, e-Devlet, BTK SIM registration, crypto-exchange licensing. Türkiye's identity rules written down in one place, which is rarer than it should be.
Industry Verticals10Where identity verification is legally required or commercially load-bearing: eSIM, SIM registration, hospitality, gig platforms, employment, age gates. Each entry names the rule that forces the check.
Solid & Personal Data Stores8Tim Berners-Lee's Solid project: WebID, LDP, WAC, RDF, and where personal data stores came from. Solidus Pod is Solid-compatible, and each entry says exactly how far that goes.
Privacy7Correlation, linkability, herd privacy, the phone-home problem: the properties that decide whether a credential system watches its own users. The questions worth asking any vendor, us included.
Security6Threat models, trust anchors, replay and man-in-the-middle attacks. The failure modes a credential system has to survive, named plainly.
