Features
Why blockchain verification matters.
Immutable record
Verdict and file hash recorded on-chain. Cannot be altered, deleted, or backdated.
Tamper-proof
Any change to the original file invalidates the on-chain hash, proving tampering.
Independently verifiable
Anyone can verify the stamp on a public blockchain explorer without a Real-Lenses account.
Legal weight
On-chain timestamps provide cryptographic proof of when the analysis was performed.
Shareable proof
Each stamp gets a unique public verification link showing the on-chain record.
Instant stamping
Reports are stamped within seconds of analysis completion. No waiting for block confirmations.

FAQ
Which blockchain is used?
We use Base (Ethereum L2) for low fees and fast confirmation. Enterprise customers can choose a custom chain.
What data is stored on-chain?
Only the verdict, confidence score, file hash, and timestamp. The actual media file is never stored on-chain.
Can stamps be removed?
No. Once recorded on-chain, stamps are permanent and immutable. This is the core value of blockchain verification.
How do others verify the stamp?
Each stamped report includes a public verification link. Anyone can open it to see the on-chain record without any account or special software.
