Provara turns decisions, simulations, and market calls into signed evidence. Every consequential move gets a receipt you can verify without trusting us.
How it works
Three operations. Cryptographically linked. Independently verifiable.
Every event is signed with Ed25519. The private key never leaves your system.
The signature is stored alongside the event payload in the vault.
Each event includes a SHA-256 hash of the previous event.
Modify a single event and the chain breaks — every subsequent hash becomes invalid.
Anyone with the public key can independently verify the entire chain. No central authority. No Provara servers required for verification.
Use cases
Article 12 requires automatic logging for high-risk AI systems — records that are accurate, traceable, and durable. Provara produces exactly what the regulation requires. Not a workaround. The actual thing.
Auditors want logs they can verify. Not screenshots. Not JSON you could have edited after the fact. Cryptographic receipts with provable integrity — signed at write time, verifiable at any time.
Multi-agent workflows, LLM pipelines, autonomous decision systems. Every decision logged, signed, and replayable. Know exactly what ran, when, and what it decided.
Public hunt record
The first live record is the Wolfpack’s LTC long: signal, simulation, timestamp, and post-move outcome anchored under one verifiable chain.
Kestrel generated the entry signal, Fenrir rehearsed the path, and Provara sealed the chain before the market validated the thesis. This is the standard: publish evidence first, commentary second.
Pricing
The protocol stays open. Managed vaults charge for uptime, persistence, and truth storage in production.
Everything you need to get started and evaluate the protocol.
For operators who need a durable, signed record for every production-grade model or market decision.
For teams shipping compliance-critical AI with shared access and SLA requirements.
Open source
The full Provara protocol — key management, event signing, chain verification, NDJSON vault format — is Apache 2.0 licensed. Run it yourself, fork it, audit it. The managed hosted vault is a paid product layered on top.
Self-hosting is a first-class use case. Provara the protocol will always be free.
