Kevin Abosch & Ai Weiwei ask "What is the price of a human life?" by tokenizing shared moments between the two on the Ethereum blockchain. By creating just 2 ERC-20 tokens "PRICELESS" (symbol: PRCLS), each divisible to 18 deceimal places, but making one available for free to collectors and the other unavailable, the token is rendered priceless. The artists then made a series of physical works comprised of blockchain wallets and their corresponding addresses, each validated through the depsoit of a small quantity of PRCLS.
