This is a bit of an unrelated update, but I still think it's important. Those that have read up on Oasis are aware that their upcoming ParaTime, Sapphire (which enables confidential smart contracts on the EVM) relies on trusted hardware, also known as TEE (Trusted Execution Environment), namely Intel's SGX (Software Guard Extenstion). The unrelated part comes that another blockchain called Secret Network that also uses TEE, was hacked by white hackers, and their master key that decrypts all the confidential information was exposed. Here's the more interesting part, the group of white hackers, featured Andrew Miller, one of the scientists of Chainlink Labs, who also co-authored the Ekiden paper, which is what Sapphire is largely based on. The Ekiden paper goes on to explain how its tech mitigates sidechannel leaks in TEE (which is the vulnerability of it), and Miller tweeted that he remained bullish on TEE smart contracts.
