We are working on getting SimpleWallet working again. |

@pirapira I just ran `make lem-thy && make simplewallet' successfully. |

@seed something similar happened to me a while ago. Isabelle2017 in Travis behaved differently from one on my local machine. I think I should check this branch on my machine and then merge the PR. |

This adds basic block program logic described in the paper "Towards Verifying Ethereum Smart Contract
Bytecode in Isabelle/HOL" published at CPP'18 and available at https://github.com/seed/ethbbl.
The logic facilitate formal reasoning about bytecode by structuring bytecode sequences
into blocks of straight-line code.
We proved the logic sound and have used it to formally verify the functional correctness of an escrow agreement smart contract implemented in Solidity.
