Abstract

Blockchain is a new technology whose purpose is to store and transfer any type of data in a decentralized manner. In this system, nodes are responsible for confirming and registering transactions, each of these nodes are distributed around the world and use different algorithms to perform their tasks correctly. In blockchain technology, data security has a very high value, and this technology can make our private information more secure and prevent the disclosure of this information. Blockchain security is ensured through various mechanisms, including advanced encryption techniques and mathematical models of behavior and decision making. Blockchain technology is the basic structure of most cryptosystems and what prevents the repetition or destruction of this type of digital currency and interference in the cycle of purchasing digital currency. In this article, in particular, blockchain security in the field of e-commerce is examined and cyber attacks against blockchain and challenges in this field are introduced.
