چکیده

بلاک چین، فناوری نوینی به شمار می‌رود که هدف از ایجاد آن ذخیره‌سازی و انتقال هر نوع داده به صورت غیرمتمرکز است. در این سیستم نود‌ها وظیفه تایید و ثبت تراکنش‌ها را دارند، هرکدام از این نود‌ها در سراسر دنیا توزیع شده‌ و برای انجام درست وظایف خود، از الگوریتم‌های مختلفی استفاده می‌کنند. در فناوری بلاک چین امنیت داده‌ها از ارزش بسیار بالایی برخوردار است و این فناوری می‌تواند تا حد زیادی اطلاعات خصوصی ما را امن‌تر کرده و از افشای این اطلاعات جلوگیری کند. امنیت بلاکچین ازطریق سازوکارهای مختلفی ازجمله تکنیک‌های پیشرفته رمزنگاری و مدل‌های ریاضی رفتار و تصمیم‌گیری تضمین می‌شود. فناوری بلاکچین ساختار اساسی اکثر سیستم‌های رمزنگاری و همان چیزی است که از تکرار یا نابودی این نوع ارز دیجیتال و تداخل در چرخه خرید ارز دیجیتال مانع می‌شود. در این مقاله به طور خاص، امنیت بلاکچین درحوزه تجارت الکترونیک مورد بررسی قرار گرفته و حملات سایبری علیه بلاکچین و چالش‌های این حوزه معرفی می‌گردد.

چکیده English

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.
