Security & Cryptographic Proofs.
Designed from the ground up for bank-grade auditability, zero-trust data handling, and regulatory compliance.
SHA-256 Hash Chaining
Every AI decision event is hashed with SHA-256 and linked sequentially to the preceding event hash. Altering any event in historical storage invalidates all subsequent hashes.
Merkle Tree Proofs
Batch event aggregations use cryptographic Merkle trees. Auditors can verify single decision records in sub-seconds without exposing surrounding data.
VPC & Air-Gapped Options
For regulated financial institutions, Blocklog deploys entirely within your AWS, GCP, or Azure VPC account. Zero data leaves your network environment.
Ed25519 Cryptographic Signatures
Evidence exports are cryptographically signed using Ed25519 signatures, providing non-repudiation and independent verification by third-party auditors.
