The Audit Chain: Permanent, Tamper-Evident, Open
The research
This is not hypothetical. Investigative reporting has documented instances of platforms altering review visibility, sometimes in response to legal threats or business relationships (Reuters, 'The Ratings Game', 2023). Even when platforms act in good faith, the inability to independently verify their data integrity undermines the trust they claim to provide.

The structural problem
Every review platform stores data on servers they control. They can, in principle, alter records. Most platforms are honest. But the architecture provides no way to prove honesty. If a platform deleted a negative review under pressure, how would you know? If a score was quietly adjusted, who would detect it? The absence of tamper-evidence is the absence of accountability.
A trust system is stronger when you can verify its claims independently, without relying on the platform's word alone. The VeriBureau audit chain is designed so that you do not need to trust us. You can verify independently.
The VeriBureau approach
The VeriBureau audit chain records every event — every review, every score computation, every Proof Token generation — as a cryptographic entry. Each entry contains a SHA-256 hash of its content and the hash of the previous entry, forming a chain. Entries are batched into Merkle trees, producing a single root hash that validates the entire batch. The audit chain is queryable via a public API endpoint. Anyone can retrieve the chain, recompute the hashes, and verify that no record has been altered.
Limitations and honest disclosure
The audit chain proves that records have not been tampered with after entry. It does not prove that the original entries were truthful — that is the role of the Proof Token system. The chain is currently hosted on VeriBureau infrastructure. We are exploring multi-anchor publication (DNS TXT records, public repositories) to reduce dependence on our servers.
Frequently asked
Is VeriBureau free?
Yes. During the founding period, all features are free with no limits. Future pricing will be per-token, not subscription — announced with advance notice.
Is VeriBureau immune to fake reviews?
No system is immune. VeriBureau raises the cost of fake reviews significantly by requiring cryptographic proof of transaction, but a business could theoretically generate tokens for fictitious transactions. We mitigate this through pattern analysis and the public audit chain, and we are transparent about this limitation.
How long does integration take?
Dashboard registration takes 2 minutes. API integration depends on your stack — most developers complete it in under an hour. No-code options (email invitations, QR codes) work immediately.
