There's I guy called Ian Grigg who was involved in the early cypherpunks of the 90s ho is very knowledgeable about Ricardian contracts, which apparently are more expressive form of contract than smart contracts. Here is a podcast of his that the devs of Hashgraph might want to listen to. He's now working on the EOS blockchain project. https://soundcloud.com/epicenterbitcoin/eb-151
