Privacy projectPhala: Confidential compute network. Technology: trusted execution environments (TEEs).
Phala runs a decentralized confidential compute cloud, where workloads execute inside attested hardware and a customer can verify what is running before trusting it with anything. It is also one of the most operationally serious teams in this corner of the field, and the field's hardest test is where that showed: when researchers extracted SGX attestation keys using a thousand-dollar hardware interposer, Phala shut its entire SGX fleet down, published the reasoning and migrated, rather than wait the news cycle out. Very few operators have moved that decisively against their own installed base. The episode is also the clearest demonstration available of what a hardware root of trust means in practice, which is that everything standing on it moves together.

What is trusted execution environment?
Computation runs inside an isolated hardware enclave whose contents the host operating system cannot read, under a hardware-trust assumption.
How it compares with the other approaches on latency, trust assumptions and fit is set out, with sources, in the technology taxonomy.
