ABSTRACT

Ethereum is one of the many cryptocurrencies that use smart contracts, and it is a well-known cryptocurrency today. Due to smart contracts, security, transaction speed, transparency and reliability are guaranteed, and secure cryptocurrency transactions are possible in blockchain technology. However, there are fatal vulnerabilities in smart contracts, and technologies are being developed to suppress and supplement them. Among them, one of the important problems occurring in the Ethereum network, a vulnerability to gas limit, exists. A gas limit vulnerability is used as a fee required when a smart contract is executed in Ethereum, but it can manipulate this gas cost to induce contract suspension, interfere with optimization, and cause DoS attacks. This consumes only the victim's gas, causes network congestion, and damages. In this paper, we propose a technique to prevent gas limitation vulnerabilities by detecting transaction data occurring in the Ethereum network in real time. Through this technique, it is possible to minimize indiscriminate gas loss and prevent gas limitation vulnerabilities in advance by detecting abnormal transactions.
