ZK gets all the hype. FHE gets the sci-fi points. But when it comes to actually usable privacy tools in Web3 right now, TEEs (Trusted Execution Environments) are doing more heavy lifting than people realize.
Came across this well-written breakdown that maps out the current state of TEEs in Web3 what’s working, what’s evolving, and where it’s headed:
🔗 https://oasis.net/blog/tees-web3-summary
Key takeaways:
TEEs aren’t some future fantasy they’re already enabling confidential voting, private DeFi, and offchain logic you can verify on-chain.
They work today, without the massive complexity of ZK circuits or the latency of FHE.
The blog goes into some solid examples: Oasis Sapphire for private Solidity contracts, ROFL for custom offchain execution, Flashbots exploring TEE-backed block building, etc.
There’s also a good section on infrastructure upgrades like multi-layer TEE defenses, reducing centralization risks, and upcoming research on physical attack resistance.
What stood out to me is how balanced the take is no silver bullet claims, just a clear-eyed view of TEEs as the “usable now” privacy layer while longer-term tech matures.
If you’re building anything in the confidential space agents, trading bots, DAO infra this is a space worth tracking.
Has anyone here played around with Sapphire or TEEs in general? Curious to hear real-world builder thoughts.
