The Global Talent Data Chain, Professional Ethics & Credit Chain (abbreviated as SVC), was initiated by the Small and Medium Enterprises Commercial Alliance Associations from countries including the United States, Japan, the United Kingdom, Russia, and Singapore. Launched in 2018, this global talent data chain system draws inspiration from the distributed storage concept of IPFS. Through the design of smart contracts, it records and stores all talent data information and content for individuals who join the SVC talent data chain, including various professional credit and capability evaluation systems. All these are encrypted and stored on the blockchain to ensure transparency and immutability throughout the process. Additionally, SVC is a system based on distributed storage consensus technology that focuses on data recording and storage proof related to talent management endeavors. It is dedicated to addressing and developing commercial solutions for transparent talent credit systems. Technically, SVC is a professional credit blockchain network based on distributed storage technology. In the era of 5G mobile technology, it will focus on governmental and business applications, serving small and medium-sized enterprises globally. It uniquely creates a desensitized and privacy-protected professional credit and capability evaluation system within the talent data domain.
