We built the evidence layer that lets an agent payment, a credential, or an audit record mean the same thing no matter who issued it. We built it so others could use it.
Canonicalisation, receipts, settlement attestation, and verification, byte-for-byte cross-validated across 8 independent implementations in 8 languages, specified in the IETF, and running in production.
It is open. Apache-2.0. Adopt it, reference us, and build whatever you are building on top of it.
- Adopt the substrate, the invitation and what is open
algovoi-substrate, the core, Apache-2.0- Conformance vectors, 27 sets, 213 vectors, 880/880 byte-for-byte across 8 languages
- IETF Internet-Drafts, the normative specs
- Adopters registry, who is already building on it
The only ask the open core makes is the one the licence already makes: keep the NOTICE, name who authored the substrate. Then build.
The capabilities being worked out across the agentic-payments ecosystem are already specified, shipped, and byte-for-byte validated here:
- freeze-at-acceptance mandate evaluation, admission-gated, with a settlement window a later mandate lapse cannot shorten
- the closed-enum signed cancellation receipt, with
EXPIREDas the unambiguous terminal-lapse artifact - a shared receipt envelope with a
receipt_typediscriminator (authorizationorcancellation) - content-addressed binding, JCS (RFC 8785) canonicalisation, and Ed25519 verification
Adopters get all of it. Our commitment: the substrate is maintained, and verifiable additions are ongoing. L2 builders are more than welcome.
Built on the same canonical evidence format and fully interoperable with the open substrate. Post-quantum receipts, zero-knowledge reputation, cross-issuer federation, and a self-serve on-premise bundle.
