A trusted execution environment (TEE) is a secure area of a main processor. It helps code and data loaded inside it to be isolated from other processes usually at a hardware level in order to provide confidentiality and integrity. Data integrity prevents unauthorized entities from outside the TEE from altering data, while code integrity prevents code in the TEE from being replaced or modified by unauthorized entities, which may also be the computer owner itself.

How does Oyster work?

Oyster is a sub-network of Marlin that specializes in offering TEE-based coprocessors. It is fast, cheap and secure. It allows instances to be rented individually for any stretch of time or for tasks to be delegated amongst a pool of nodes in a serverless way without individually renting instances and paying only for the duration of the task's execution. Nodes can be rented and tasks delegated using both smart contract calls and web 2 APIs. A set of auditors routinely query Oyster nodes to ensure uptime guarantees.

What are the benefits of using Oyster?

Oyster is very flexible and versatile. Developers can port existing web 2 applications on Oyster, write code in the programming language of their choice and use popular libraries and frameworks. Additional benefits include: 1. Secure: Hardware isolation ensures that programs run correctly as intended without exposing their contents and prohibiting interference from the host machine or its owner. 2. Fast: Oyster nodes are essentially like usual servers. There’s no redundancy in computation, complex protocol logic or cryptography. Thus, apart from a little TEE overhead for encrypted memory access, Oyster nodes are very performant and provide an experience similar to running programs on a normal machine. 3. Cheap: TEEs can be considered commoditized. While a little more expensive than vanilla servers, they are very cheap compared to blockchains, MPC, FHE or ZK proofs. Consequently, TEEs are a very affordable mode to carry out computations verifiably.

How can I get involved?

Oyster is a permissionless network. As such, programmers can contribute to its codebase, developers can build trustless web 3 applications by deploying their backends on Oyster nodes and infrastructure providers can run TEE-enabled Oyster nodes.
