The Trusted Execution Environment (TEE) is a computing environment designed to provide high levels of security and isolation through a combination of hardware and software, and it has garnered widespread attention in the field of blockchain security. The core idea is to leverage hardware-level support to create an independent "secure zone" within the system, ensuring that sensitive data is processed only within verified applications through isolation, thus preventing unauthorized access, malicious tampering, and potential attacks from other parts of the device, providing a solid guarantee for data security. To explore whether TEE can become another milestone in trusted privacy computing on blockchain, Web3Caff Research has specially released this report, written by researcher Professor Tom. The report will use Flashbots and Scroll as examples to discuss the applications of TEE in optimizing transaction sorting, reducing MEV issues, and ensuring data security and verification accuracy in zero-knowledge proofs. It will serve as a starting point to analyze its technical principles and development prospects. In summary, this report contains many highlights worth exploring in depth, which you certainly cannot miss.
