Block Building inside SGX | Flashbots

We are excited to announce that Flashbots is running a block builder inside an SGX enclave, and open-sourcing all the components.

We are excited to announce that Flashbots is successfully running a block builder inside an SGX enclave, a trusted execution environment (TEE) developed by Intel . The SGX block builder is now live on the Ethereum Sepolia testnet, and soon on mainnet! Our previous work on running Geth inside SGX demonstrated the technical feasibility of this approach. Now, we’ve made the next step towards block building inside encrypted enclaves, and want to share our key learnings and challenges, as well as the all the code and tooling for running a block builder inside SGX.
