In the future, it will integrate with Compound, and five other DeFi protocols, according to its website.Encrypted blockchains provide transparency for the protocol but privacy for the users, so people aren’t required to show their identities when transacting, Williamson said.“The world isn’t nice to live in without encryption,” Andrews said. “Go through your day and think about how many things you wouldn’t want people to see. Not all of it is bad; it’s just your daily life
