Blockchain technology can play a critical role in art authentication and ownership by providing a secure and transparent way to track the provenance of artwork.

Currently, the art market is plagued by forgeries and counterfeits, and there is a lack of transparency around ownership and provenance. Blockchain can address these issues by providing a decentralized and tamper-proof record of artwork and ownership.

This can help to increase trust and transparency in the art market and make it easier to authenticate and track artwork.

Additionally, blockchain can be used to create digital certificates of authenticity for artwork, which could be stored on the blockchain and used to verify the authenticity of a piece.
