Security Analysis Methods on Ethereum Smart Contract Vulnerabilities — a Survey
1 Security Analysis Methods on Ethereum Smart Contract Vulnerabilities — A Survey Purathani Praitheeshan?, Lei Pan?, Jiangshan Yuy, Joseph Liuy, and Robin Doss? Abstract—Smart contracts are software programs featuring user [4]. In consequence of these issues of the traditional both traditional applications and distributed data storage on financial systems, the technology advances in peer to peer blockchains. Ethereum is a prominent blockchain platform with network and decentralized data management were headed up the support of smart contracts. The smart contracts act as autonomous agents in critical decentralized applications and as the way of mitigation. In recent years, the blockchain hold a significant amount of cryptocurrency to perform trusted technology is being the prominent mechanism which uses transactions and agreements. Millions of dollars as part of the distributed ledger technology (DLT) to implement digitalized assets held by the smart contracts were stolen or frozen through and decentralized public ledger to keep all cryptocurrency the notorious attacks just between 2016 and 2018, such as the transactions [1], [5], [6], [7], [8]. Blockchain is a public DAO attack, Parity Multi-Sig Wallet attack, and the integer underflow/overflow attacks. These attacks were caused by a electronic ledger equivalent to a distributed database. It can combination of technical flaws in designing and implementing be openly shared among the disparate users to create an software codes. However, many more vulnerabilities of less sever- immutable record of their transactions [7], [9], [10], [11], ity are to be discovered because of the scripting natures of the [12], [13]. Since all the committed records and transactions Solidity language and the non-updateable feature of blockchains.
