The Age of CryptoCurrency, the recently released book by Wall Street Journal reporter Paul Vigna and senior columnist Michael J Casey, has been permanently recorded on bitcoin’s public ledger, the blockchain.

The book is the first by a major publisher with its exposure and interest to have a time-stamped digest recorded in the blockchain, actively demonstrating the technology beyond just the subject of the book.

Digital Currency Council (DCC) director of curriculum Dan McArdle copied the book into Block 341705 using the firm’s Blockchain Recordation Toolbox, which allows DCC professionals access to blockchain recordkeeping for clients. The process used open source platform Proof of Existence.

McArdle said:

“This hash is unique to the book, and therefore could not have been generated before the book existed. By embedding this hash in a bitcoin transaction, the existence of the book on that transaction date is logged in the most secure and irrefutable recordkeeping system humanity has ever devised.”

Vigna and Casey received a certificate representative of blockchain recordation process. The record is now fully transparent on the blockchain.

The process was confirmed in under an hour.

The ‘Age of CryptoCurrency’ can be purchased with bitcoin on Overstock.
