The durability platform for organizations that can't afford to be wrong. Verify every claim, anchor every record, and prove it — permanently.
Granite Proof combines cryptographic anchoring, real-time verification, and a zero-trust audit layer into a single unified platform.
Every record, document, or event is hashed and anchored to an immutable ledger the moment it's created. Tampering is mathematically impossible to hide.
Verify the authenticity of any record in under 50ms via API. Works on-chain and off-chain — so your existing infrastructure doesn't need to change.
A single pane of glass for every access event, mutation, and attestation across your entire stack. Search, export, and share audit reports in seconds.
Define fine-grained trust policies that auto-enforce across teams, APIs, and integrations. Every action must prove it's allowed — no exceptions, no overrides.
Granite Proof is designed for teams that need trust fast — without months of infrastructure work.
Drop in our SDK or hit the REST API directly. We integrate with S3, Postgres, Kafka, and any webhook-capable system in under 10 minutes.
Use our policy builder to declare which records, events, or fields require anchoring. Start broad, narrow down — policies live in your repo as YAML.
From the moment a record enters scope, Granite Proof hashes, timestamps, and anchors it automatically. No manual steps. No gaps.
Share cryptographic proofs with auditors, regulators, or partners via a link. They can verify independently — no Granite account required.
Join the open beta and start anchoring your first 10,000 records — free, forever. No credit card required.
