Abstract: Blockchain is a distributed data structure that integrates security, reliability, and centralization. It is the central support technology of the emerging digital encryption currency. With the emergence of Bitcoin, blockchain as its underlying support has begun to attract great attention and has been initially applied in the fields of finance, stocks, and securities. This article briefly describes the classification, architecture, and key technologies of blockchain. At the same time, it briefly analyzes the key management, access control mechanism, DDOS attack defense mechanism, and fragment information leakage prevention mechanism in the blockchain security mechanism. Finally, the prediction of the future development trend of blockchain aims to help further studies on blockchain and its security.

Key words: digital encryption, key management, DDOS attack, access control, information leakage
