cryptography

What use-cases would be enabled by a network of distributed, mutually-verifying TEEs with high availability, and MPC between them?

Does such a network already exist?

Censorship resistance requires privacy.

At least for the TEEs, what comes to mind is the idea of facilitation of verified secure boot of open source code on offchain ec2s. For instance, today Mullvad uses TEEs to facilitate secure boot of their VPN servers in what I assume is a standard approach. Users trust Mullvad and Mullvad uses the TEE to verify against certain attack vectors that they have less control over. In a distributed TEE environment, TEEs could validate that some person who volunteered to run a VPN node is running the correct code, and that it hasn't been tampered with. This might allow for some reduction in the cost of security/trust-reduction since maybe you don't need as much in terms of econ incentives to deter the operator from messing with the node.
