Your audit evidence.
Quantum sealed.
Tamper-proof forever.

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.

How It Works

Three steps. Immutable evidence.

01

Log

Ingest events via SDK, webhook, or API. Every action your system takes becomes a log entry with actor, action, resource, and metadata.

02

Seal

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.

03

Verify

Anyone can verify any seal using our public endpoint. No account needed. Auditors verify client evidence with a single URL.

The Quantum Difference

Why standard audit logs aren't enough.

Quantum Nonce

Each seal uses entropy from IBM Quantum hardware via QuantumRand — not pseudorandom generators.

Hash Chain

Every entry cryptographically links to the previous. Tamper with one, the entire chain breaks forward.

HMAC-SHA256

Server-side signing with a secret key prevents client-side forgery of seals or timestamps.

Immutable Timestamps

The sealed_at timestamp is locked at seal time. Backdating is mathematically impossible.

Public Verification

Auditors verify evidence at qal.dev/verify — no account, no software, no friction.
