Sculpture using the new Bronzechain technology, licensed by DACS to approved art foundries, will be stamped with a hallmark in the wax before casting. A digital certificate of authenticity will be recorded by DACS and stored using cryptography by art verification service Verisart.

Two years in the making, Bronzechain was developed following a conversation between DACS and the British sculptor Maurice Blik, who expressed concern around the number of fake modern bronzes on the market.

Blik’s works – on show at Bowman Sculpture in London until May 4 – were the first to be hallmarked. DACS says the cost for using the technology will be £5 per work.
