Richard Yu, Pengbo Si, Zhaoxin Yang, and Yanhua Zhang Abstract—Blockchain, as the underlying technology of crypto-currencies, has attracted significant attention. It has been adopted in numerous applications, such as smart grid and Internet-of-Things.With the more and more extensive application of blockchain, blockchain security has been widely concerned by the society and deeply studied by scholars. Moreover, the security of blockchain data directly affects the security of various applications of blockchain. In this survey, we perform a comprehensive classification and summary of the security of blockchain data. First, we present.A Survey of Blockchain Security Issues and Challenges. Int. J. Netw. Secur. Blockchain technologies is one of the most popular issue in recent years, it has already changed people's lifestyle in some area due to its great influence on many business or industry, and what it can do will still continue cause impact in many places.Attacks rely on a vulnerability being present so that they can exploit it. These vulnerabilities are implemented in software (web services, smart contracts, the underlying blockchain system, etc.) and can be any number of weaknesses such as logic bugs, reentrancy issues, integer overflows and so on.Owing to the increasing demand for cryptocurrency and its current security challenges, previous studies have not focused on blockchain technology cybersecurity vulnerabilities extensively.

In this survey, we perform a comprehensive classification and summary of the security of blockchain data. First, we present.In this paper, we systematically explore the attack surface of the Blockchain technology, with an emphasis on public Blockchains. Towards this goal, we attribute attack viability in the attack surface to 1) the Blockchain cryptographic constructs, 2) the distributed architecture of the systems using Blockchain, and 3) the Blockchain application context. To each of those contributing factors.Blockchain implementations are often designed with a specific purpose or function. Example functions include cryptocurrencies, smart contract s (software deployed on the blockchain and executed by computers running that blockchain), and distributed ledger systems between businesses.Owing to the increasing demand for cryptocurrency and its current security challenges, previous studies have not focused on blockchain technology cybersecurity vulnerabilities extensively.
