(1) Ethereum contracts as Legal Contracts; (2) Intro to zero-knowledge proofs

Tom Johnson will describe the conditions under which an Ethereum or other smart contract can be a legal contract. Tom is a patent attorney in San Jose (see who has written on Bitcoin ( . Tom talked with us once previously; that event was supposed to be on this topic, but because of time limitations he only covered legal aspects of cryptocurrencies.  Christian Peel will also give a intro to zero-knowledge proofs including the Fiat-Shamir ID protocol.
