INTRODUCTION TO SMART CONTRACTS AND SOLIDITY LECTURE BY SARISHT WADHWA
ETHEREUM A distributed ledger? Not accurate State Machine! State: Large data structure which saves machine state (instead of just accounts and balances) Update is defined by a set of pre-defined rules, that can execute arbitrary code. Ethereum Virtual Machine: Rules of changing state to state from block to block
SMART CONTRACT Both parties code the actions that they need to perform in a pre- defined programming language Solidity . The miners or block proposers ensure that the code is correctly executed, and the fair exchange goes through between the parties.
WHAT IS SOLIDITY? Solidity is a type of object-oriented programming language. This programming language has been built specifically for writing smart contracts on the Ethereum Blockchain. It is inspired mainly by JavaScript, but also has relations to Python and C++. Solidity codes are compiled in the Ethereum Virtual Machine.
