An Overview of the Research in the Security Issues of Ethereum Ecosystem

Abstract

Blockchain is a revolutionary technology that enables users to communicate in a trust-less manner. It enables users to store data globally on thousands of computers in an immutable format and empowers users to deploy small pieces of programs known as smart contracts. The blockchain-based smart contract enables auto enforcement of the agreed terms between two untrusted parties. There are several security vulnerabilities in Ethereum blockchain-based smart contracts, due to which sometimes it does not behave as intended. Because a smart contract can hold millions of dollars as cryptocurrency, so these security vulnerabilities can lead to losses. We present a review of the security issues in the Ethereum ecosystem.
