Crovia Substrate — The Signed Ledger of AI Behaviour

What am I looking at?

The Substrate is Crovia's signed temporal ledger of AI behaviour. Every line in axiom_ledger.jsonl is one AXIOM envelope: a signed, canonically-serialised JSON record of a single observation (a training-data claim, a robots.txt directive, an arXiv paper version, an autonomous probe result, etc.).

Envelopes are periodically hashed into a Merkle tree, the root is signed with an Ed25519 key whose fingerprint is in TRUST_ROOT.md, and that root is anchored to Bitcoin via OpenTimestamps. This page shows envelope data.

To prove any single envelope independently, click its axiom_id anywhere on this page — it opens the client-side verifier, which downloads a static proof bundle (envelope + Merkle path + seal signature + Bitcoin anchor) and re-runs every check in your browser. No trust in Crovia required. Open protocol: AXIOM Receipt v1.

132 targets have been independently witnessed by 3 or more collectors (5 at maximum score 4). This is forensic-grade evidence: no single collector can fabricate it. open the Diamond Archive →

Live collectors · ingestion health

Each row is an independent ingestion source that feeds envelopes into axiom_ledger.jsonl. Status is computed from the ledger itself (no self-reporting): active = ≥1 envelope in the last 24h, weekly = ≥1 in the last 7d, dormant = seen in the last 60d, dead = silent ≥60d. Public endpoint: collectors.json.

Bitcoin anchor · OpenTimestamps

Every ledger seal Merkle root is anchored into the Bitcoin blockchain via OpenTimestamps. Once a stamp is confirmed in a Bitcoin block, the proof becomes verifiable offline against Bitcoin block headers — independent of Crovia's infrastructure. See canon/TRUST_ROOT.md § Bitcoin timestamp anchor.

Envelope verifier

Paste an axiom_id (starts with axm_) to verify it client-side against its Ed25519 signature, Merkle inclusion, and Bitcoin anchor. Verifier runs entirely in your browser — no trust in Crovia required. Spec: AXIOM Receipt v1.
