Verifying the Hash Chain Independently

For technical users: how to independently verify the hash chain without trusting Borderly.

Auditor

Overview

If you want to verify the hash chain yourself (without relying on Borderly's verification portal), you can do so using the raw data and standard cryptographic tools.

How to Verify Manually

The process involves:

1

Export the raw data

From the verification portal, go to the Toolkit section and download the raw record data.

2

Compute the SHA-256 hash of each record

For each record, compute its SHA-256 hash using the record's data fields plus the previous record's hash.

3

Compare hashes

Verify that each computed hash matches the stored hash. If all hashes match, the chain is intact.

4

Verify timestamps (optional)

Download the RFC 3161 timestamp tokens and verify them against the Timestamping Authority's certificate using standard tools like OpenSSL.

The verification portal's Toolkit section provides tools and documentation to help with independent verification.
