I went back and reread the article, I got confused when they explained the hybrid Dapp. I was definitely not thinking in the encryption of Tauchain knowledge.

I think you are suggesting that contributions towards a topic develpment in Tauchain (as well as the Tauchain source code), will be keep secure using TEE (or a mix of TEE and sMPC) I can definitely see the value in such combination, and I hope the parties involved in the project are looking out for the intellectual property of the developers/contributors.

Thank you.
