CONTENT VERIFICATION
Check the original
When an Article or Note is published, Meridian automatically creates a publication record and sends it to Solana. To verify that publication, recalculate the original's hash and compare it with the on-chain record.
Choose “More → Source record” on an Article or Note to check it.
Back to reading →How the check works
- 1
Create a record at publication
Publishing an Article or Note records its text, attachments, ID, and capture time, then calculates a hash. Drafts are not recorded on-chain.
- 2
Record it on Solana
The hash is written into a Solana transaction. Once finalized, neither Meridian nor the author can overwrite the record in that transaction.
- 3
Check the published original
Recalculate the text and attachment hashes, compare them with the on-chain record, and check the signature and time. Verification passes only when all checks pass.
Common questions
Can the original record be changed after publication?
No. A finalized publication record cannot be overwritten. Changing its text, attachments, ID, or capture time changes the hash, so it cannot pass verification against the original record.
Can republishing make new content look like the old record?
No. An update creates another record linked to the previous one, with its on-chain time set by a new Solana transaction. The original record remains. A new record cannot rewrite its content or time.
Can changing the ID bypass verification?
No. The ID is part of the hash calculation. Changing it or the text breaks the match with the original Solana transaction. Verification uses the record in that transaction, and you can keep its direct link.
Are drafts recorded on-chain?
No. Drafts do not enter the publication record. Articles and Notes are recorded on-chain automatically after publication and can be checked once the transaction is finalized.
How can I check it myself?
Open the Solana record from the results page to see its hash and confirmation time. You can also download the verification data, calculate the file's SHA-256 hash, and compare it with the hash in that transaction.

Have a verification link or record number?
Paste it below. The check starts when the record opens. A record number is just a way to find it.
