A method that uses Bitcoin or Bitcoin-like technologies to authenticate that a certain information was published at a certain date, or was known at a certain date.

The technique entails encoding the secure hash of a certain publication (plaintext) inside the Bitcoin blockchain. It was probablly first described in the paper from 2012 titled "CommitCoin: Carbon Dating Commitments with Bitcoin" (extended abstract and technical report).

One website that provides an easy gateway to Proof of Publication is ProofOfExistance.com.
