There have been efforts to add privacy to Ethereum L1, such as stealth addresses[1] and EIP-7503[2]. [1]: https://vitalik.eth.limo/general/2023/01/20/stealth.html [2]: https://eips.ethereum.org/EIPS/eip-7503

However, the state of L1 privacy today is: - No Ethereum wallet supports stealth addresses. - EIP-7503 isn't slated for inclusion. - Tornado Cash is sanctioned by OFAC. - Its developers are in jail. - There is nothing on Vitalik's roadmap[3] around privacy.

L2s can't have real privacy if L1 doesn't have privacy. Since rollups' security properties requires the ability for an L1 user to force inclusion of a transaction in a rollup, then true L2 privacy only exists if there is a way to do force-inclusion without revealing the identity of the L1 or L2 user in the process.

It seems clear that this is an under-researched area of Ethereum. Yet it is an area that, if Ethereum is maximally successful but nothing is done on L1 privacy before Ethereum ossifies, Ethereum would have created a surveillance dystopia.

Tim Beiko (@tim) has stated as such in a recent AMA, and wishes that folks would spend 20% of the brainpower spent on solving MEV towards solving L1 privacy[4]. [4]: https://warpcast.com/tim/0x01dc4ab8

Can you explain the state of L1 privacy as you see it? How do you think about its prioritization on the Ethereum roadmap? How can I, as a non-cryptography-expert Ethereum user who care about privacy, help make L1 privacy become a serious consideration for the evolution of Ethereum R&D going forward?

This post is meant as a question for @justindrake's orb at https://justin.orb.land/ but doesn't fit in 140 characters (the Orb's question length limit), so I posted it here instead.

As per the Orb's terms, I understand that this means Justin is technically no longer bound to actually answer this question, unless he wishes to do so anyway. I'm hoping he does :)

The SHA-256 hash of the above question is 5ad309be5a8d2ece94c65fcccdc5238d1913e9da088e9fd082e8c879fd9b60a6, as can be verified with the following command: ``` $ ipfs cat QmSqMAsNdvLMbL9AmAQWSZAchEFrkkr8Ux6NLumcqk2cDn | sha256sum ``` (Yes, I realize the IPFS CID is itself a hash and that this is redundant.)
