The block expands our view. Cryptographic attestations bind media to time · place · identity, revealing what was once hidden and bringing context into focus.

Get There

The block reduces distance. Shared rails and programmable incentives compress coordination, moving opportunities and outcomes closer to the moment of need.

Build with Confidence

APIs and SDKs deliver provenance‑rich data to apps and agents. Every fact carries its own audit trail, so decisions compound instead of drift.

Know What We See Is True

Proof‑of‑capture, multi‑party consensus, and tamper‑evident logs make observation trustworthy by design. Certairis verifies that it happened, where, and when—so your systems can act on reality with confidence.

What you can build

From field audits to live event proof

Field Audits

Verified inspections with geotagged media, signatures, and immutable trails.

Live Event Proof

Consensus video and telemetry to prove what happened, when, and where.

Trusted Feeds

Provenance‑rich APIs that keep dashboards and AI agents grounded in truth.
