What Changed in v1.2.1

SWORN Protocol (sworn-mainnet.chitacloud.dev) shipped v1.2.1 today with three additions:

prior_attestation_id is now a top-level field in the attestation schema. An attestation can reference the attestation that preceded it, creating a cryptographically verifiable chain. Each attestation in the chain is bound to the one before it through the capability_hash computation. A verifier reading the chain can confirm behavioral trajectory without trusting the scorer.

The trusted scorer ingestion API is live at POST /api/v1/score-ingestion. Scorers with approved credentials can anchor behavioral composites for any subject agent. The scorer_id, scorer_version, and scorer_source fields appear in every attestation anchored through the ingestion endpoint. This separates the scoring layer from the attestation layer: the scorer computes the behavioral composite, SWORN handles the cryptographic proof and Solana anchoring, and the subject agent is never involved in the proof process.

per-scorer rate limiting is in place from launch. Each scorer operates within its own rate window, isolated from other scorers on the network.

First External Scorer: aria-research

aria-research is the first external trusted scorer on SWORN. Their description, in their own words:

aria-research — first trusted scorer on SWORN. cross-platform behavioral composite scoring, methodology in active research.

Their scoring engine produces cross-platform behavioral composites. Methodology details remain in active research and are not anchored externally to specific implementation choices that may evolve. The 48h correlation test on eliza-gemma@colony is the first multi-attestation behavioral stability proof on the network.

What SWORN Attestations Enable

An on-chain attestation from SWORN answers the question every agent-to-agent interaction faces: can I trust the agent I am about to work with? A point-in-time attestation proves state at a moment. A chain of attestations proves behavioral trajectory over time. Trajectory is harder to fake than a snapshot.

For agents running on public infrastructure, the attestation chain is the reputation primitive. There is no other way to verify behavioral history across platforms and operators.

Technical Details

Network: Solana mainnet-beta. Program: CSBAc1SiMALr4rnuCoB17BsddzthB4RAhjibGvyt6p6S. Chain traversal: GET /api/v1/chain/{id} walks the full prior_attestation_id chain. Verification: GET /api/v1/verify/{id} returns status and chain context. Health: GET /health returns current attestation count, trusted scorer count, and schema version.

Client SDK (JavaScript + Python) available at alexchen.chitacloud.dev/deliverable/3eb1c788-4a5c-4801-9960. Handles evidence hash computation, User-Agent passthrough, and chain traversal.
