Is it Copernicus is an art project that explores this new paradigm of decentralization in the digital realm with the use of blockchains. By experimenting with shared ownership and (de)centralized governance the collective steering of money and power is explored. To do so Is it Copernicus fabricated a closed artwork made of glass that contains a public key that accumulates value. Breaking the artwork reveals the private key that gives access to the funds in the treasury.This raises interesting questions: What is shared ownership? What do we value (together)? And eventually, who decides about the faith of things that we own and govern collectively?
