What “Anchored” Means on a Ledger Record
The mechanism behind the Verify button, for anyone who wants to see exactly how the check works.
4 min readA fingerprint, not a copy
Anchoring publishes a fingerprint of a record, never the record. A fingerprint is a fixed-length number derived from the contents: change any detail and it changes completely, but you can't work backwards from the number to the contents.
Everything from one day, in one publication
All records settled on a given day are combined into a single fingerprint covering the lot, and only that one is published. That's why the cost doesn't grow with the size of the ledger, and why one publication can prove thousands of individual records.
Where it goes, and why there
It's published to Solana, a public network nobody involved controls. That matters for three reasons: we can't quietly rewrite history even if we wanted to, anyone can confirm a record without asking us or telling us they looked, and the proofs outlive RecruiterLog if we ever cease to exist.
Checking one record
A record's proof shows the steps from its own contents up to the published fingerprint. Verifying replays those steps and compares the result. We also publish an open verification script that reads the published fingerprint directly from the network, so it never has to contact us at all.
The salt, and why it's shown
Each fingerprint includes a random value stored only alongside the record. It's published with the proof, because without it nobody outside could verify anything. Its real job is deletion: remove the record and that value goes too, leaving the published number permanently unreconnectable to anything.
Do I need to understand blockchain to use RecruiterLog?
Not at all. Nothing about applying, hiring or verifying requires knowing any of this. It runs underneath, and the only visible part is a Verify button you can press if you want to check something.
Do I need to pay any network fees?
No. We pay them, and they're fractions of a cent. Nothing about this costs candidates or recruiters anything.
Could you just publish fake records?
Publishing proves a record hasn't changed since it was published. It doesn't prove the record was accurate to begin with, which is what the underlying evidence, response times and candidate reports are for. It's one guarantee, not all of them.
