Defi (Decentralized Finance) core technology is Secure Multi-Party Computation (SMPC) based on Blockchain. We belive that Defi (SMPC+Blockchain) is the next paradigm after Ethereum(Smart Contract+Blockchain). With its world-leading technology and engineering capabilities, Defi aims to serve the 2 billion people who are mostly unbanked in SouthEast Asia, and truly be a blockchain company that serves the next billion. Defi Data Collaboration Protocol provides access to collaborate on high quality secure and shareable data. This new infrastructure can enable and encourage more frequent transparent and trustful data sharing between Southeast Asia consumer finance institutions and individuals. Financial institutions can better assess and control risks and individuals can have better access to better services while the privacy of both enterprises and individuals data is better protected. Furthermore, data from various sources can join computation to maximize the value of data and yet keep data security.
