区块链技术由于其不可篡改、可追踪溯源等技术特性，能够很好地解决跨系统业务交互中的数据信任和数据协作难题，成为实现政法跨部门协同办案的关键技术力量。中国电信依托自主可控的翼平安权证链技术体系，打造“区块链+政法跨部门协同办案平台”，推动政法各部门业务系统间的数据共享和业务协作，实现了案件办理的全程留痕，可追溯、可监督，进一步促进了规范执法、公正司法。
In response to the technical and business pain points faced by cross-departmental collaboration in law enforcement，blockchain technology，with its technical features such as immutability，traceability，multi-party consensus and smart contracts，can effectively solve the data trust and data collaboration problems in cross-system business interaction，and become the key technology force for achieving cross-departmental collaboration in law enforcement. China Telecom relies on its self-controllable Wing Security Chain technology system to create a “blockchain + cross-departmental collaboration platform for law enforcement”，which promotes data sharing and business collaboration among various law enforcement departments，realizes the whole process of case handling with traces，traceable and supervised，and further promotes standardized law enforcement and judicial justice.
