Sovryn is a decentralized financial protocol built on Bitcoin, instead of the traditional ETH DeFi model. It allows its users to lend, borrow and leverage their assets natively on Bitcoin without sacrificing custody of their keys. Users have direct say in the governance of the development of the protocol using the Bitocracy system. Edan Yago is one of the earliest contributors to Sovryn and has been involved in Bitcoin since 2011. He believes DeFi will overtake CeFi in terms of wider use and become the dominant system.
