Solidus Identity
Solidus Identity vs Trinsic
Trinsic has rebuilt its business model twice since 2019 chasing product-market fit in SSI. Solidus is younger and unproven in a different way — no revenue either — but the protocol underneath doesn't change shape every two years.
Solidus is a public testnet: no mainnet, no token, no external audit, and no paying customer. Every claim below is checkable; none of them are a substitute for the certifications an incumbent already holds.
What Trinsic does better
- Real developer-channel thought leadership: Riley Hughes publishes prolifically and the Trinsic blog is a genuine reference for the SSI space, per the brief.
- A self-serve developer experience the brief itself calls 'closest to Persona's quality bar in the SSI space' — Solidus has no comparable content or DX track record yet.
- A standards-agnostic acceptance layer that interoperates across multiple SSI ecosystems (Polygon ID, Indicio, Mattr issuance compatibility) — one integration for many credential sources, which Solidus doesn't offer.
- A real Series A (~$10M, 2022, led by Kleiner Perkins) and five-plus years operating with actual, if small-to-mid-market, developer customers, per the brief.
Where Solidus is different
- L1 protocol, Apache-2.0 open source, and native KYC issuance — three structural things Trinsic's own brief says it lacks, having been SaaS-only with a closed core platform through all three pivots.
- did:solidus is registered in the W3C DID Method Registry — a standards foothold independent of any one vendor's business model, which doesn't erode if a company repivots.
- Native KYC issuance via Verify in the same stack, where Trinsic's brief states it defers to and partners with issuers.
