Public Ledger Transparency

Every hour, SoilVector submits the latest state of each organization's audit ledger to an independent timestamp authority. This creates cryptographic proof that the ledger existed in its current state at that time.

Recent anchors

Each row represents a cryptographic snapshot of one organization's ledger, witnessed by an independent third party.

No anchors yet

Anchors will appear here once the first organization's ledger has been timestamped by a TSA.

How to verify independently

Each anchor includes an RFC 3161 timestamp token signed by an independent Timestamp Authority. Anyone can verify these proofs.

1

Download the TSA token

Each anchor has one or more tokens signed by independent Timestamp Authorities like FreeTSA.org.

2

Download the CA certificate

Get the TSA's root certificate from their website (e.g., freetsa.org/files/cacert.pem).

3

Run verification

Use OpenSSL to verify the token against the certificate. A "Verification successful" confirms the proof.

OpenSSL command

openssl ts -verify -data anchor_digest.bin \
  -in token.tsr -CAfile cacert.pem

A "Verification successful" result confirms that the ledger digest existed at the stated time, as witnessed by an independent third party.

What does this mean?

SoilVector maintains an append-only, hash-chained audit ledger for every organization. Each record is cryptographically linked to the one before it, creating a tamper-evident chain.

External anchoring goes further: it proves that the ledger has not been retroactively altered — even by SoilVector itself. If any past record were modified, the chain head would change, and the mismatch with the anchored proof would be immediately detectable.

These proofs are published here for anyone to verify. No trust required — only math.
