TEEX is a secure distributed computing platform which provides a Layer-2 solution based on blockchain. It builds a complete incentive model of computing resource sharing, which provides a decentralized, usable and flexible computing market for users, workers and service providers. TEEX team members are from the first research group in China that has been focused on TEE including Intel SGX, AMD SME/SEV, ARM TrustZone and RISC-V since 2012. Our papers are published on top-tier international conferences including ISCA, HPCA, USENIX Security, CCS, USENIX ATC, MobiSys, EuroSys, NDSS, DSN, etc. In 2015, we released T6, the first open-sourced TEE OS in China, which evolves into a commercial product and gets deployed in tens of millions of devices. Our project, ShadowEth, applies TEE to public blockchain and supports private smart contract in a practical way. The related paper was accepted in Jan 2018, which is the first peer-reviewed paper discussing privacy and scalaibility on public blockchain.
