To help market participants navigate such volatile market conditions, we present a decentralized platform named DUO Network, which enables issuance, trading, and settlement of tokenized crypto derivatives. It mainly consists of Collateralized Autonomous Tokens (CAT), Price Oracle, CAT Exchange, and DUO Network Token. The platform aims to reduce risks and barriers in traditional derivative transactions, through collateralized smart contracts and distributed price feeds, thereby creating a transparent and autonomous derivative marketplace. DUO Network is a Singapore-based blockchain project initiated by FinBook Pte Ltd in the fall of 2017. The team came from diverse backgrounds with extensive experience in trading, consulting, blockchain, information technology, and entrepreneurship.
