20.03.2018 7 Ethereum • Blockchainwith expressiveprogramming language – Programming language makes it ideal for smart contracts • Why? – Most public blockchainsare cryptocurrencies SMART CONTRACTS FROM ETHEREUM TO POTENTIAL BANKING USE CASES PAGE 3 One real world implementation of a smart contract that gained mainstream coverage was The DAO, a distributed autonomous organisation for venture capital funding, which was launched with US $150 million in crowd funding in May 2016. Ethereum is a major blockchain-based platform for smart contracts – Turing complete programs that are executed in a decentralized network and usually manipulate digital units of value. Solidity is the most mature high-level smart contract language. Ethereum is a hostile execution environment, where anonymous attackers 4 SMART CONTRACTS TODAY: ETHEREUM 10. Whilst the idea for operation of a smart contract was formulated by Nick Szabo9 in 1996, it is through the rise of cryptocurrencies and blockchain technology, particularly Ethereum, A survey of attacks on Ethereum smart contracts 5 Miners execute a transaction until its normal termination, unless an excep-tion is thrown. If the transaction terminates successfully, the remaining gas is returned to the caller, otherwise all the gas allocates for the transaction is lost. This paper proposes a modeling method of an Ethereum application based on smart contracts, with the aim of applying a formal method, namely Model-Checking, to verify that the application
The Ethereum Virtual Machine or EVM is the runtime environment for smart contracts in Ethereum. It is not only sandboxed but actually completely isolated, which means that code running inside the EVM has no access to network, filesystem or other processes. Smart contracts even have limited access to other smart contracts.

It can be used to reverse-engineer contracts into a representation that is indeed easier to

Ethereum avoids this problem by introducing the concept of gas, a fundamental cost unit for the network, which is paid by a cryptocurrency called Ether to execute Ethereum is a public blockchain with a built-in Turing-complete language to allow writing any smart contract and decentralised application.

A survey of attacks on Ethereum smart contracts 5 Miners execute a transaction until its normal termination, unless an excep-tion is thrown. If the transaction terminates successfully, the remaining gas is returned to the caller, otherwise all the gas allocates for the transaction is lost. This paper proposes a modeling method of an Ethereum application based on smart contracts, with the aim of applying a formal method, namely Model-Checking, to verify that the application Smart contracts extend the idea of a blockchain to a compute platform for decentralized execution of general-purpose applications. Contracts are programs that run on blockchains: their code and state is stored on the ledger, and they can send and receive coins. Smart contracts have been popularized by the Ethereum blockchain.
