Unsurprisingly, catalogues raisonnes are a hotbed of legal activity and controversy. Many scholars will now not offer opinions on the authenticity of a work for fear of getting sued:
Due to the misaligned incentives in the art authentication world, I'm going to go out on a limb and suggest that a blockchain would be a good way of tracking records in the artworld, particularly if artists register works directly on it.
By putting your artwork on the "BitCoin Blockchain",
Verisart will hand wavy magic increase the trust in
art dealers and reduce fraud.
That's a pretty neat idea. A distributed public ledger of
who I have sold my art to. And, if they sell it, they have
a cryptographically signed certificate proving its
provenance. The seller can sign the certificate with their
private key to say they've sold it to the new owner of a
specific public key. Nifty!
Except… and I hate to bring the art industry into
disrepute… what if I sell a fake and keep the original in
my Underground Vault?
There's no way to permanently attach a digital certificate
to a physical work of art.
Incidentally, this is the problem with all the startups
claiming the blockchain will revolutionise the integrity
of global logistics markets. Sure, you can slap a QR code
on a crate - but nothing stops an unscrupulous middle-man
from replacing or adulterating the contents of the crate.
Let's get back to Verisart's other issue. Proving that I
am the creator or owner of a piece of artwork.
Long story short, I convinced them that I painted the Mona
Lisa.

And works with supposedly excellent provenance still end up being repudiated by authentication committees:
