Patent Application Eyes Bitcoin Blockchain for Artwork Provenance

A newly-published patent application seeks to use blockchain technology to establish and maintain a chain-of-ownership for artwork.

The patent application, which was published by the U.S. Patent & Trademark Office (USPTO) on Thursday, lists the framework’s inventor as Howard H. Sheerin, a patent attorney in Scottsdale, AZ. According to Sheerin’s LinkedIn page, he now works in Silicon Valley, where he has been “studying and actively participating in the cryptocurrency revolution, including to draft multiple Bitcoin/Blockchain patent application.” His website also indicates that he accepts bitcoin.

Writing in the patent application, Sheerin notes that certificates of authenticity are crucial to enabling sellers to obtain the full value of their artwork in auctions and other sales. However, paper certificates are inadequate guarantors of provenance.

He writes:

“Artists have in the past issued paper certificates of authenticity for each art piece they create so as to increase the value of each art piece for subsequent buyers. When a second buyer is interested in purchasing an art piece from a first buyer, the first buyer may present the paper certificate of authentication with the art piece in order to prove their legal and legitimate ownership of the art piece. However, paper certificates may be easily forged which greatly diminishes the value and efficacy of this authentication system. There is, therefore, a need for a better system to authenticate art pieces that is not easily circumvented.”

Sheerin hopes to patent a system that would allow artists to establish and transfer ownership rights using the Bitcoin blockchain or another cryptocurrency network.

Of course, the difficulty with using a blockchain to establish a chain-of-ownership is that there is an element of trust involved with the original registration of ownership.

Last month, for example, blockchain critic Terence intoEden tricked one such artwork provenance service — Verisart, which registers art on the Bitcoin blockchain —  providing him with a certificate of authenticity confirming that he painted La Gioconda, better known as the Mona Lisa, Leonardo da Vinci’s 16th-century masterpiece.

Even now, a month after Eden’s story went viral on social media, he is listed as the verified owner of the Mona Lisa, a “fact” that is permanently engraved in the immutable Bitcoin blockchain.

Sheerin’s proposed system appears to employ a similar architecture, for though ownership is established using bitcoin addresses, this data is maintained through a centralized chain-of-ownership (COO) website.

Consequently, it seems that while such a system could increase the ease with which artists can establish and transfer ownership rights, it still requires parties to place their trust in the centralized entity who maintains the database and verifies the information contained therein.

Update 7/13: Howard Sheerin, whose proposed system has been implemented at, reached out to with the following comment: “ is a website that implements embodiments of the patent application. does not suffer from the deficiency of Verisart described in the article. The reason, as described in the patent application, is because with each artist is assigned a master bitcoin address from which all of their art pieces are linked. In other words, only an art piece that is linked to the artist’s master bitcoin address is considered legitimate, and only the artist can link their art pieces to their master bitcoin address. Eden does not control Leonardo da Vinci’s master bitcoin address, and so Eden could not register himself as the painter of the Mona Lisa with This is a true and elegant use of the bitcoin blockchain.”
