How is this similar to:

"Instead of posting customer hashes to a public digital ledger, Surety creates a unique hash value of all the new seals added to the database each week and publishes this hash value in the New York Times. The hash is placed in a small ad in the Times classified section under the heading “Notices & Lost and Found” and has appeared once a week since 1995." ?

How is it similar? I think we could rephrase it.

- Post a hash of a document to Twitter.

- Put a hash of a document in an ad in the NYT.

Quite similar.
