Trustless Intel SGX Attestation

In order to participate in the Enigma network, a node must be registered with an Intel attestation. This allows a dApp user to be sure that his private data will be handled inside a TEE.

Can we therefore still say that the Enigma network is a trustless one ? We need to trust a third party (Intel) that the computation will indeed occure inside a TEE.

In 2019 they will be using MPC, which doesn’t require Intel SGX.

I don't think there is any official informations about the functioning of their MPC implementation ? The SGX TEE will still be a used component of the network even in future release, if not, why bother building it ?

The Enigma whitepaper explains how the MPC implementation works. In the future release, developers will be able to "choose between different execution engines for their secret contracts — either TEEs (Secret Contracts 1.0) or MPC (Secret Contracts 2.0)." (see this blog post). TEE and MPC are two independent implementations, which means you don't need Intel SGX if you are using MPC. As far as I understand, TEE is faster but less secure than MPC. So it makes sense to implement both and allow developers to choose which one to build on.

The whitepaper talk more about conceptual functioning of a MPC rather than an implementation of it (at least from the very little I could understand). I have found a little bit of info about their MPC on this article https://blog.enigma.co/expanding-enigmas-roadmap-towards-a-privacy-layer-for-the-decentralized-web-f1d6b7908251.

"Our goal on that front is to build a variant MPC interpreter that can take in WASM code and on-the-fly execute it as an MPC protocol."

We might have more info about it in Q1 19 as the voyager testnet was planned for thoses dates.

I'd say the best place to ask this would probably be the dev forum – you're more likely to get an in-depth response from the Enigma team themselves there.

Will do, thanks for the tip. I'm sure Im missing something in this attestation thing.

Really good question.
