KairoNull is an AI governance evidence infrastructure platform. Cryptographic audit trails and tamper-evident decision records for regulated financial institutions. EU AI Act Article 12 compliance. SHA-256 hash-chained decision records, RFC3161 timestamps, independently verifiable.
EU AI Act Article 12 Compliance
EU AI Act Article 12 requires high-risk AI systems to maintain automatic, tamper-evident logs. KairoNull's Umbra Trust Protocol is built to address this with cryptographic hash-chain architecture. Annex III obligations, including Article 12, are fixed at 2 December 2027 following the Digital Omnibus. Article 50 transparency obligations and AI Office enforcement powers activate 2 August 2026.
AI Governance Evidence Infrastructure
KairoNull is an Evidence Engine for AI decisions in regulated environments. Every decision is evidence-chained, hash-sealed, and independently verifiable. Built for regulated financial institutions under EU AI Act, MiCA, AIFMD, and FCA frameworks.
AI Audit Trail
Cryptographic AI audit trail using SHA-256 hash chaining. Each decision event: input, model version, prompt, output, timestamp, sealed and chained. Independent verifiability without vendor involvement.
AI Governance Evidence Infrastructure | KairoNull
We don't ask organisations to trust AI. We give them the evidence to verify it.
AI governance evidence for organisations operating under AI regulation, audit requirements, and fiduciary obligation.
The Problem
AI systems are making decisions that affect money, people, legal outcomes, and regulated processes. Organisations need cryptographic proof that cannot be quietly changed.
What KairoNull Does
KairoNull is cryptographic audit infrastructure for AI systems. Every AI decision captured, sealed with SHA-256 hash chaining, and independently verifiable. Built to meet the authentication, integrity, and chain-of-custody standards courts apply to digital evidence, and designed to support the evidence standards regulators and auditors expect.
Who It Is For
Financial services, banking, legal firms, healthcare, biotech, insurance, human resources, and any institution where AI decisions carry regulatory consequences under the EU AI Act, ISO 42001, GDPR Article 22, or NIST AI RMF.
How It Works
Four phases: Observe every AI input and output at the moment of generation. Evaluate each decision against configured governance policies. Record results to a tamper-evident SHA-256 hash-chained ledger. Prove compliance on demand with cryptographically verifiable audit packages.
Independent Verification
Every KairoNull evidence record can be verified using standard OpenSSL tools without access to KairoNull systems. Tamper with any record and every subsequent hash breaks immediately.
