Every log entry is sealed with a quantum nonce from IBM Quantum hardware. Mathematically impossible to backdate, tamper with, or fabricate. Trusted by compliance teams and verified by Big 4 auditors.
Ingest events via SDK, webhook, or API. Every action your system takes becomes a log entry with actor, action, resource, and metadata.
Each entry is sealed with a quantum nonce + SHA-256 hash chain + HMAC-SHA256 signature. The seal is immutable and cryptographically linked to every prior entry.
Anyone can verify any seal using our public endpoint. No account needed. Auditors verify client evidence with a single URL.
Each seal uses entropy from IBM Quantum hardware via QuantumRand — not pseudorandom generators.
Every entry cryptographically links to the previous. Tamper with one, the entire chain breaks forward.
Server-side signing with a secret key prevents client-side forgery of seals or timestamps.
The sealed_at timestamp is locked at seal time. Backdating is mathematically impossible.
Auditors verify evidence at qal.dev/verify — no account, no software, no friction.
Whether you're from Deloitte, PwC, EY, or KPMG — verify any quantum-sealed audit log entry or evidence package with a single GET request. No login. No software. Just proof.
