The big finance co’s in ‘08 thought that by using Black-Scholes they could mitagate risk, but instead increased it.
Replying to @petertoddbtc
it wasn’t that they didn’t understand Black-Scholes ‘08, but underestimated human irrationality would move systematic risk.

IBM’s Open BlockChain #IBMOBC smart contracts are called chaincode: “can be written in any programming language”: https://github.com/openblockchain/obc-docs/blob/master/FAQ/chaincode_FAQ.md
I’m not quite comfortable calling parallel confirmation of the execution of general purpose program a #SmartContract.
Instead, in a #SmartContract language I’m seeking a system where both the identity and consensus layers are intimately intertwined.
