The design of Obscuro ensures that hardware manufacturers do not have to be trusted for the safety of the ledger. If one manufacturer turns malicious or there is a breach in the TEE technology, the protocol falls back to the behaviour of a public blockchain that preserves the ledger’s integrity but makes the transactions public. This situation will lead to a partial liveness failure because the withdrawal function will be suspended.
The design also focuses on preserving privacy for the limited period when it matters most, which removes the need for a privacy technique that is robust against all adversaries in perpetuity.
Obscuro sits in what we believe is a sweet spot between the existing rollup-based L2 offerings Optimistic and ZK Rollups. The use of confidential computing techniques coupled with economic incentives allows Obscuro to retain the performance and programming model simplicity of Optimistic rollups, and on top of that attain confidentiality, short withdrawal periods, and address MEV.
Obscuro is a decentralized Layer 2 privacy solution built on top of Ethereum. Obscuro is designed to enable any Ethereum contract to operate at a larger scale, lower gas, without risk of MEV and crucially, with full privacy. It leverages a technology called Trusted Execution Environments, it's the technology that secures most of your devices. TEEs provide complete privacy, even from the operators of the host machines.
