There is a push towards multi-proofs in rollups, SGX in particular is a prime candidate:
- 2FA zk-rollups using SGX - zk-s[nt]arks - Ethereum Research
- Twitter space: Multi-proofs for rollups a nice-to-have or a necessity, with Vitalik (Ethereum Foundation), Protolambda (Optimism) and Brecht (Taiko)
- Taiko: Why multi-prover matters. SGX as a possible solution.
Having this precompile would solve a big gas cost headache and enable SGX verification without relying on Intel chain of trust.
