AI systems make decisions.
Nobody can prove what they decided.
The EU AI Act Article 12 requires high-risk AI systems to maintain automatic logging of autonomous decisions — tamper-evident, retained for at least six months, available to regulators on demand. Enforcement begins August 2026.
Existing approaches fail in one of three ways: application-level logs are mutable and unverifiable; third-party audit tools bolt on after the fact and miss real-time decisions; blockchain solutions introduce unacceptable latency for production AI pipelines.
A financial institution using GPT-4o for credit decisions makes 40,000 autonomous determinations per day. Under Article 12, every one must be logged with sufficient detail to reconstruct the decision context. No existing infrastructure handles this at scale.
The penalty for non-compliance is up to 3% of global annual turnover — for a $10B institution, that is $300M per year.
One line of code.
Every decision attested.
Rubric embeds at the framework level — not the application level. A single call at startup instruments every LLM call, agent decision, and tool use automatically. No per-decision code. No codebase audit. No latency impact.
Each attestation receives a unique ID, is cryptographically signed with ML-DSA-65 (NIST FIPS 204 post-quantum signature standard), aggregated into a Merkle forest, and anchored to Hedera Consensus Service — a public, immutable, verifiable ledger with Byzantine fault-tolerant consensus.
Built for production scale.
Not a proof of concept.
Rubric uses a three-tier aggregation architecture that achieves 1,000,000:1 compression for HCS writes — enabling billion-scale daily throughput at minimal on-chain cost.
Post-Quantum Cryptography
All signatures use ML-DSA-65 (CRYSTALS-Dilithium), standardized by NIST in FIPS 204 (August 2024). Rubric's implementation uses a native N-API C++ addon via liboqs, delivering 52× faster signing than pure JavaScript implementations. Attestations signed today remain verifiable against quantum adversaries.
Payload Privacy
Decision payloads are encrypted with AES-256-GCM before storage. The customer holds the encryption key — Rubric stores only the ciphertext and a cryptographic commitment. Rubric cannot read your AI decisions. Regulators receive the key from the customer directly for audit purposes.
Beyond decisions.
The full agent accountability stack.
Modern AI systems are not single-shot decision engines — they are autonomous agents that reason across multiple steps, call external tools, maintain state across interactions, and delegate to other agents. Rubric attests the entire stack, not just the final output.
Tool Call Attestation
Every external tool invocation — web search, code execution, API calls, database queries — is attested with hashed input/output pairs, duration, success status, and chain linkage to the prior attestation. This is where AI risk actually lives: not the reasoning, the action.
Agent State Hashing
At every decision point, Rubric captures a SHA3-256 hash of the agent's current memory,
context window, and system prompt — capped at 4KB to bound storage impact. Two identical
decisions made from different mental states produce different state hashes, making behavioral
drift cryptographically detectable. State hash type is recorded as full or
truncated for audit transparency.
Chain Linking
Every attestation carries a priorAttestationId reference, forming a
tamper-evident chain across the agent's full session. Deleting or reordering any
attestation breaks the chain. The complete reasoning sequence — from initial input
through every tool call and state transition to final decision — is cryptographically
sealed and independently verifiable.
Agent Identity Registry
Each agent is registered with a stable W3C DID anchored to Hedera mainnet and a dedicated ML-DSA-65 (NIST FIPS 204) keypair. Agents are first-class cryptographic principals — auditors can verify which agent acted, not just that an agent acted. Registration records include jurisdiction, permitted uses, model hash, and version.
The combination of tool call attestation, agent state hashing, chain linking, and cryptographic agent identity transforms Rubric from a compliance logging tool into a constitutional enforcement layer — the accountability infrastructure that makes autonomous AI systems deployable in regulated environments.
Global regulatory compliance.
Computed automatically from intent.
Declare your AI system's intended use and jurisdiction. Rubric computes your complete regulatory obligation set automatically — mandatory fields, applicable articles, safe harbor conditions, and a ready-to-paste SDK configuration. No compliance expertise required.

Your existing tools.
No custom integration.
Every attestation is exportable in three formats on demand. Pipe directly into your existing GRC or SIEM platform — no custom integration, no professional services engagement.
| Format | Use Case | Platforms |
|---|---|---|
| JSON | API integration, custom dashboards, data warehouses | Any system with REST API support |
