03 // Security & Architecture
Bezpieczeństwo jest
fundamentem.
Not a feature, not an add-on. Our architecture is designed around the principle that even we cannot alter your data.
Separation of evidence
Attesto stores proofs separately from the source systems. Manipulation is detectable even when the original environment is later disputed.
Trust architecture
When the same system creates the event, controls the log, and generates the audit report, everything depends on one trust boundary. Attesto breaks that dependency.
Hardware-level signing
Keys live in TPM or HSM. No human, no admin, no root can forge a signature.
Privacy-preserving proofs
Prove properties without exposing raw underlying data. Compliance evidence without unnecessary data leakage.
Multi-node consensus
No single point of trust. Events are validated by independent nodes.
Public anchoring
Periodic Merkle roots on Polygon. Independently verifiable for as long as the chain, timestamp records and retained Merkle proofs remain available.
Tamper-evident logs
Any attempt to modify breaks the chain. Sabotage is mathematically visible.
EU data residency
EU-hosted deployment options designed to reduce international transfer exposure and support GDPR transfer-risk assessments.
