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

In this last video he talks about the use of messaging rather than state reach consensus in a system. It seems similar to gossip approach in a way. He has a paper called Financial Cryptography in 7 Layers. He says that many projects fail because they don't take into account all the various levels of knowledge needed for a successful decentralised system. Might be worth looking into also. http://iang.org/papers/fc7.html https://link.springer.com/chapter/10.1007/3-540-45472-1_23
