随着区块链系统中业务量的快速增长，系统延迟增加，吞吐量低等性能问题就会凸显。尽管区块链技术较好地实现了链内的数据共享，但由于不同区块链间采用的数据结构、共识机制、加密算法等技术路线不一致，会导致链与链间的数据难互通、信息难交互、身份难识别。需要在跨链技术与跨链协议方面进行突破，实现链与链数据共享和更广范围的价值互联。
区块链合同流程规范发布
当前假冒电子签名、假冒公章等事件屡见不鲜。随着数字经济社会发展，越来越多的合同通过互联网、电子化的形式订立。基于区块链的电子合同对于确保用户真实身份、真实意愿、不可篡改等需求提供了极好的解决方案，提供高可信、高易用、高智能的数字化合同服务。
全程可溯
区块链电子合全流程在区块链记录，并且区块链各节点可证，不会丢失。
合法有效
区块链电子合同的流程、内容遵循《中华人民共和国电子签名法》、《中华人民共和国民法典》等相关法律法规的规定，保证区块链电子合同的法律效力。
不可篡改
区块链电子合同全流程信息进行区块链存证，并保证信息不可篡改。
安全可信
区块链电子合同全流程应基于密码学的机制进行安全保障，区块链平台和第三方区块链电子合同服务平台应具备身份认证、电子签名、可信环境等功能，保障区块链电子合同安全可信。
Explore the blockchain with the integration of technology and application to realize the benign development of the industry. The application of blockchain technology and industrial innovation answer Virtual Currency Exchange Platform digital currency With the rapid growth of business volume in the blockchain system, the system delay increases, and the low throughput will be highlighted. Although the blockchain technology has better realized the data in the chain, the virtual currency exchange platform in digital currency, the virtual currency exchange platform in digital currency, and the virtual currency exchange platform in digital currency. With the rapid growth of business volume in the blockchain system, the system delay increases, and the throughput is low, so the performance problems will be highlighted. Although the blockchain technology has achieved data sharing in the chain, it is difficult to exchange data and information between chains due to the inconsistency of technical routes such as data structure consensus mechanism encryption algorithm adopted between different blockchains. It is difficult to identify. It is necessary to make breakthroughs in cross-chain technology and cross-chain protocols, realize chain-to-chain data sharing and a wider range of value interconnection. Blockchain contract process specifications are released. At present, incidents such as counterfeiting electronic signatures and official seals are common. With the development of digital economy and society, more and more contracts are concluded in the form of electronic internet, which provides an excellent solution to ensure that users' true identities and true wishes cannot be tampered with, providing high credibility, high ease of use and high intelligence. The whole process of digital contract service can be traced back to the blockchain, and all nodes in the blockchain can prove that the legal and effective blockchain electronic contract will not be lost. The content of the process follows the provisions of People's Republic of China (PRC) Electronic Signature Law, People's Republic of China (PRC) Civil Code and other relevant laws and regulations to ensure that the legal effect of blockchain electronic contract cannot be tampered with. The process should be based on cryptography to ensure security. The blockchain platform and the third-party blockchain electronic contract service platform should have the functions of identity authentication, electronic signature and trusted environment to ensure the safety and credibility of blockchain electronic contracts. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台

区块链技术存在哪些挑战
运维管理：多方参与的区块链系统在运维管理方面将会面临巨大的挑战，例如系统升级、系统维护、业务规则更新等，需要多方线下沟通才能处理链上的协同治理问题。
可信和安全性：在区块链应用中，安全性威胁与可信问题不容忽视。为提高自主可信和安全性，应采用国密加密算法，支持可信执行环境 TEE，优先选用拥有自主知识产权的关键技术。
互操作性：尽管区块链技术较好地实现了链内的数据共享，但由于不同区块链间采用的数据结构、共识机制、加密算法等技术路线不一致，会导致链与链间的数据难互通、信息难交互、身份难识别。需要在跨链技术与跨链协议方面进行突破，实现链与链数据共享和更广范围的价值互联。
