Vitalik: Ethereum is exploring recursive STARK mempools to address quantum security and privacy scaling challenges

PANews September 22 reported that ETHShanghai, jointly hosted by ETHPanda, PANews, and The Excited Few, 2026 officially kicked off today in Shanghai. Ethereum co-founder Vitalik Buterin delivered an online speech on EIP-8288 the topic. Vitalik said that Ethereum is exploring the introduction of recursive STARK mempool mechanisms to alleviate the tension between quantum security, privacy protection, and network scaling. Currently, post-quantum signature verification costs may reach 100000 to 300000 Gas; transactions involving privacy proofs may consume hundreds of thousands or even millions of Gas. As the adoption of post-quantum signatures and privacy technologies expands, the on-chain verification burden may increase further. The core idea of the proposal is to separate signature and proof verification from on-chain execution, with mempool nodes handling transaction ver...

Key points

ETHShanghai 2026 opens in Shanghai.
Vitalik Buterin delivered EIP-8288 an online speech.
Vitalik stated that Ethereum is exploring the introduction of recursive STARK mempool mechanisms.
Post-quantum signature verification costs may reach 100000 up to 300000 Gas。
Transactions involving privacy proofs may consume hundreds of thousands or even over million.Gas。
The proposal plans to separate signature and proof verification from on-chain execution, with mempool nodes handling transaction validation.

AI-assisted interpretation

The following is analysis, separate from reported facts. Verify important claims independently.

In simple terms, this exploration aims to move some signature and proof verification work from on-chain execution to mempool nodes, thereby reducing the verification burden.

Why it matters to readers

As the adoption of post-quantum signatures and privacy technologies expands, the on-chain verification burden may increase further.

This indicates that Ethereum is exploring mechanisms to address quantum security, privacy protection, and network scaling simultaneously.

Risks and unknowns

The original text is truncated at “with mempool nodes processing transactions…”, so the complete mechanism and subsequent content cannot be confirmed.
Recursive STARK The mempool is still described as a mechanism that is “being explored for introduction”; its implementation status cannot be confirmed.
