A start-up called the Blockchain Art Collective (B.A.C.)is the newest part of a constantly growing ecosystem of start-ups testing how to use blockchain technology to standardize unpredictable aspects of the art industry. What B.A.C. (along with other start-ups experimenting in the field) recognized in blockchain technology was its potential to store information about artworks—like records of sale and provenance—to provide their creators, owners and prospective buyers with an unaltered digital record of the work’s history.
