Lutra's HOA A1 camera records each photo's provenance on a public blockchain

South Korean startup Lutra has launched Humans of Authenticity (HOA). Its first camera, the A1, binds each photo's capture data to an anonymous certificate recorded on a public blockchain, a shared ledger. A name overlay toggles on or off. The camera has no rear screen. The 100-unit First Edition is expected to ship December 1 at $289 for US buyers.
