Survey on blockchain ecosystem common security risk analysis

Blockchain has been evolved from the initial design of cryptocurrency to a widely applied technological foundation as a decentralized distributed infrastructure and novel computing paradigm, providing new impetus for the development and transformation of the digital economy. However, numerous risks and challenges have also been brought to the ecosystem composed of blockchain technology and application environments, including the technical security risks inherent in blockchain itself and those arising from its integration into existing systems. In-depth analysis and research on these risks have been of great significance for promoting the benign development of blockchain technology and ecology. Firstly, a comprehensive and systematic analysis and evaluation of these two types of risks were conducted, with the causes, impacts, and mitigation measures for each risk being summarized, thereby providing strong guidance for security management and risk control of existing blockchain projects. Subsequently, six security objectives for the development of blockchain ecology security were proposed, and based on these objectives, a comprehensive, multi-dimensional blockchain project security assessment framework was constructed, aiming to promote the healthy development of the blockchain ecosystem and provide robust support for building a more secure, stable, and efficient blockchain application environment.
