This indicates that the privacy protection technology of Chinese technology companies in the field of blockchain has been highly recognized by the international community < p > it is understood that ITU is the world's leading communication standards organization, which was founded in 1865. Its members include more than 190 countries, more than 900 companies and academic institutions. It is also an authoritative international standardization organization in the world < p > the technical standard of this project is composed of ant chain, cloud computing and < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%A4%A7%E6%95%B0%E6%8D%AE "> big data < / a > and the privacy computing alliance jointly proposed to protect the data security and privacy of enterprises when serving on the application chain < p > according to IDC's forecast, the overall expenditure scale of China's blockchain market will reach US $2.28 billion in 2024, with a compound annual growth rate of 51%. As all walks of life accelerate to embrace the blockchain, the problems of data security and privacy protection on the chain become more and more prominent < p > for industrial stakeholders, the core value of blockchain lies in the establishment of a multi-party cooperation and mutual trust network. However, in high-frequency trading scenarios such as finance, due to the large scale of intelligent contract operation, the performance of existing technical solutions is significantly degraded, even up to 100 times in extreme cases, which limits the implementation of blockchain applications < p > according to the introduction of ant chain, based on its business practice, it has independently developed a privacy protection technology scheme with high security, high usability and high performance in complex financial business scenarios. With the rapid growth of business data, this scheme can ensure the data privacy and integrity, and minimize the cost of privacy protection calculation“ The ITU project not only means that ant chain has been continuously practicing in multiple business scenarios, and data protection has been recognized by international authorities, but also provides a reference for global blockchain industry in data privacy protection on the chain. " The person in charge of the ant chain said
