Regulatory Auditing under the EU AI Act: A Checklist

The EU AI Act mandates strict logging for high-risk autonomous systems. Discover how to build compliant, tamper-proof logs.

Meeting EU AI Act Compliance Standards

Under new compliance frameworks, developers must provide chronological logs showing how autonomous choices were validated. ATL-Trust generates cryptographic, structured logs recording every intent, validation output, and TEE signature, ensuring auditability.

Our ledger implementation outputs block records containing detailed timestamps, intent actions, values, and verification outcomes. This structured format satisfies compliance requirements automatically.

// Appending action logs to ledger
pub fn append_action(&mut self, action: String, asset: String, value: f64, outcome: String) -> Result {
    // Records outcomes...
    self.save_to_file()
}

Tamper-Proof Block Creation

The ledger chains each transaction block with SHA-256 signatures, building a permanent, exportable audit trail that proves compliance to regulators. This provides mathematical assurance that history was never altered.

By logging validator executions on-device, we establish a secure record of agent compliance that can be audited at any time, protecting organizations from regulatory fines.
