Luca Cosentino, product lead at Oasis Labs, joins Ash Bennington, Real Vision senior editor, to discuss Oasis Labs, the different layers of the crypto technology stack, and DeFi. Cosentino describes Oasis as being a layer 1 blockchain, a base protocol, where smart contracts can be hosted. As layer 1 is the base layer from which applications get their security, he explains the protocols and applications built on top of this layer as layer 2. Cosentino mentions that the Oasis network aims to provide private smart contract inputs and increased scalability compared to other layer 1 blockchains such as Ethereum, and he also walks through some of the primary difficulties of DeFi with existing blockchain layer 1s such as scaling up transaction throughput and front-running. Filmed on March 8, 2021. Key Learnings: Oasis Labs aims to be a layer 1 blockchain with improved privacy to combat front-running since DeFi, as it exists today, has been plagued with scalability issues and privacy problems.
