Immutable timestamps on our records

Every change to a donation, a field report or a certificate is written to a log that cannot be edited, and the fingerprint of that log is published to the Bitcoin blockchain.

Read this before you read the hashes

What this proves: that our records were not quietly rewritten after the fact. Once a fingerprint is in a block, any later edit — by us, by an administrator, by anyone with database access — stops matching it.

What this does not prove: that a record was correct when it was written. If a field report says 1,000 trees and that was wrong, the timestamp preserves it as permanently wrong. Trust in the number comes from independent field verification, not from the chain.

No money and no NFT is held on a blockchain here. Donations move through regular payment rails and certificates live in our database. What goes on-chain is a 32-byte fingerprint and nothing else.

How it works

1
Every significant action — a settled donation, a verified field report, an issued certificate, a withdrawal — writes a row to an audit log. The database physically refuses to update or delete those rows.
2
Every few hours the rows written since the last run are hashed into a single Merkle root, using the same tree construction as Certificate Transparency.
3
That root is sent to independent OpenTimestamps calendars. They aggregate thousands of roots from many parties into one Bitcoin transaction, which is why this costs nothing and needs no wallet.
4
Once the transaction is mined, the proof is upgraded and names a block height. From that moment, the timestamp no longer depends on us or on the calendar operator.

Verify it yourself, without us

We publish an endpoint that recomputes the root, but that only shows we agree with ourselves. The check worth doing uses the reference OpenTimestamps client, which talks to Bitcoin and has no reason to take our word for anything.

pip install opentimestamps-client
curl -o anchor.ots https://earth365.org/api/anchors/<id>/proof
ots verify --digest <merkle-root> anchor.ots

A successful verification tells you the fingerprint existed at that block time. To check that the fingerprint still matches today's records, ask us for the inclusion proof of a specific record.
