Vitalik Buterin published a proposal to reduce the cost of private transactions with quantum resistance by more than 99% within the Ethereum network. The document, identified as EIP-8288 and co-authored with Thomas Coratger last June, aims to be included in I-star, the Ethereum upgrade scheduled for after Hegota.
The central mechanism of the proposal consists of moving the heaviest cryptography out of the network’s execution path. Today, a private transaction with quantum resistance can cost around 10 million gas, given that post-quantum signatures weigh between 2 and 3 kilobytes and STARK proofs can exceed 128 kilobytes.

This is an EIP that I am hoping we can get included in I-star (the fork after Hegota) that you can think of as the next step after Frames, that would unlock extreme amounts of power. Particularly:

Under the proposed scheme, each transaction declares a “dependency,” a 96-byte fragment, and mempool nodes generate every second a single recursive STARK proof that covers all declarations in the block. The result, according to Buterin, would be bringing costs down to tens of thousands of gas.
The proposal also implies adopting RISC-V as Ethereum’s canonical instruction set, a decision that Buterin himself described as important and one that must be made carefully. EIP-8288 also depends on EIP-8141, the transaction redesign into “frames” that Vitalik pushed forward days ago and which also has no assigned fork date.
