Blockchain certification service for digital art copyright launched by Polline

Polline, a digital art gallery that won the Culturability Prize in 2015, has launched Polline Blockchain Mark, a service using blockchain technology to certify and protect copyright for digital artworks. Presented in Venice during the Architecture Biennale vernissage, the system combines digital signatures and timestamps to create an immutable public ledger. Each transaction and ownership operation is notarized in a chain of blocks, ensuring security, reliability, and irreversibility. The blockchain acts as an international notary, preventing copyright violations ex ante and enabling artists to assert authorship ex post. The service operates on a peer-to-peer model without a central authority, with each transaction validated by all network nodes. John Naughton of The Guardian described blockchain as an "incorruptible ledger of data blocks."
