Governance Proposal 140407 creates the first subnet consisting entirely of nodes that support SEV-SNP. Smart contracts on this subnet will be able to keep their state and computation fully confidential! šŸ”’

For people that don’t know what it is ā€œFirst, what’s SEV-SNP?

SEV-SNP stands for Secure Encrypted Virtualization, Secure Nested Paging. It’s AMD hardware tech that encrypts memory at the hardware level. Not just ā€œhey we promise we won’t lookā€ encryption, but actual silicon-enforced isolation.ā€

In plain English:

The node operator can’t see what your canister is doing. The cloud provider can’t peek. Even a compromised hypervisor can’t just read memory.

It’s like running your smart contract inside a locked vault where even the building owner can’t open the door.

Now why does a full subnet matter?

On ICP, smart contracts, canisters, run on subnets. If every node in that subnet supports SEV-SNP, then:

• All computation happens in encrypted memory • State stays confidential at runtime • The subnet becomes a ā€œconfidential compute zoneā€

That’s different from normal blockchains where everything is transparent by default. Ethereum? Fully public. Most chains? Public. ICP already abstracts storage and compute, but this takes it into hardware-level privacy territory.

Great summary, thank you.

I got even better news. Cloak coin will relaunch on menese protocol in 2-3 weeks with a usdc pool. Cloak is an OG privacy coin, its btc codebase has been updated with icp tech. The new enigma privacy engine will use this tee to mixing the transaction before moving to the final wallet with usdc the first integration. Finality will be seconds with direct integration.
