Terminology● Encryption● Hashing● Proof of work (mining)● Transaction verification● Smart Contracts

● Immutability● No single point of failure etc.● Mix crypto/rules/gametheory

Smart Contract Demo

● Ethereum Private Network● A smart contract

IofT challenges

● Problem to solve?● Architecture● Two fold

Problem to solve?

● Bitcoin keep money honest proof of work● Ethereum keep contracts honest proof work

gas● Maidsafe keep data honest proof of resource● IofT + Health ?● – keep science honest proof of evidence
