Prove the hardware you ran on is real.
Attestation is a signed statement from the enclave's hardware proving what it is and what image it booted. It's how you know the "trusted hardware" is actually trusted.

prove the machine
A proof of computation only matters if the machine doing the computation is real. Attestation closes that gap — the hardware itself signs what it is, and you verify that before you trust the rest.
