A new proposal suggests allowing individuals to stake between 4 to 32 ETH to register a Trusted Execution Environment (TEE) attestation verification key or certificate root. This would enable the TEE to automatically join the network, with the risk of deposit slashing if an invalid attestation is proven. The design aims to be fully generic, eliminating the need to enshrine any specific TEE type. Additionally, the proposal hints at the possibility of participation without a TEE by staking 10 ETH and using personal nodes, though this approach is noted to be less capital-efficient.
