Recommended: 4,000 art auction houses are putting their sales records on the blockchain (
A recent merger between a blockchain-based art registry and an international auction house sales database will see sales records from over 4,000 auction houses put on the blockchain.

The art registry, Artory, has purchased Auction Club, a currently privatized database that contains information from over 4,000 international auction house sales, the Art Newspaper reports.
Volume 0% The acquisition will merge the two companies immediately and will make Auction Club’s sales records from over 250 businesses in 40 countries publicly available for the first time. Records will begin to show up on the blockchain-based registry some time in May.

The data held in Auction Club’s database dates back to the 1970s, including digitized information about major sales that have taken place over the last 40-plus years.To view the database you need to be registered with and vetted by Artory. So it’s not entirely “public.”

The Registry

Artory records the auction data on a permissioned (private) implementation of the Ethereum blockchain in a distributed ledger it calls The Registry.The Registry records events in an art works life cycle like when it’s gone under auction, what it sold for, when it sold, and what it is.

However, if you thought you’d get to find out who bought that latest record-breaking artwork, I’m sorry to disappoint, but The Registry doesn’t record the details of art owners.

Art-buyers are also provided a secure digital record of the history of each artwork, with digital certificates generated every time it gets sold. The idea is that this provides the greater art market with a certain confidence in an artworks’ ongoing provenance.

That said, there is one glaring security concern, the Artory Registration card.


When an auction house sells a piece of artwork, the buyer can request the auction house to complete an Artory entry and issue a digital blockchain-based certificate and registration card.

The registration card holds sensitive information like the seed phrase and “private cryptographic key,” open for the whole world to see. This key is also generated by Artory, so you can’t be totally sure you’re the only one to ever see it.

Even if it is hidden behind a “scratch off panel,” it doesn’t sound particularly secure.If the registration card fell into the wrong hands, it could allow bad actors to alter information in The Registry.

Hard Fork has contacted Artory seeking clarification on its security measures.

Back in November last year, major auction house Christie’s made history by tracking $317.8 million worth of art auctions via Artory’s blockchain, as one of the greatest privately owned collections of American Modernist art went under the hammer.

Still though, this feels like yet another “why blockchain?” moment, considering a centralized database could do pretty much the same job (and probably do it better).

Did you know? Hard Fork has its own stage at TNW2019, our tech conference in Amsterdam. Check it out.

    Francisco Gimeno - BC Analyst Art in blockchain is a good idea, not just to know who are creators of an art work, but to deal with ownership's changes, all kind of records, and copy rights, etc. A centralised database could do that, but the database in a blockchain platform assures of immutability and deals with a very important factor in the world of art: trust.
