| ## Disclosure | ||

| The proposed design outlined in this EIP incorporates certain features that may be subject to claims in pQCee's patent-pending application (PCT [WO2023080842](https://patentscope.wipo.int/search/en/detail.jsf?docId=WO2023080842)). While it is important to ensure that adoption of the proposed post-quantum signature scheme remains accessible to all Ethereum stakeholders, this has to be balanced against the need to recognize and acknowledge the intellectual property rights associated with its development. We recognize the value of fostering an open and collaborative ecosystem that promotes widespread adoption and innovation within the Ethereum community, and as such, we welcome constructive dialogue with interested parties to explore appropriate licensing arrangements of the patented technologies to achieve these objectives. |

EIPs are meant to be open for anyone to implement. I do very much appreciate this disclosure, but I don't believe we can accept a proposal unless it also includes an irrevocable patent grant.

Thank you for the feedback. This current design is preliminary. We will further engage the community to get more feedback regarding this.

Hi @SamWilsn , I would like to check if there's further actions required on my part to facilitate the advancement of the pull request? |

We have a slight preference for SVGs, if you can provide them. If not, PNG is fine.

| Quantum computers, when powerful enough, can be used to break cryptography used in Ethereum. Specifically, using Shor's algorithm on a cryptographically-relevant quantum computer (CRQC), an attacker will be able to create an exact copy of the private ECDSA key when given the public ECDSA key without needing access to the wallet. This will essentially allow the attacker to steal assets associated with any wallet on Ethereum. | ||

| In order to ensure Ethereum continues to operate as a trusted decentralized platform for users and organizations to transact, the threat of quantum computers needs to be mitigated. Vitalik Buterin also wrote a post on 9 March 2024 titled "How to hard-fork to save most users’ funds in a quantum emergency" on the mitigation of the quantum threat on Ethereum ecosystem. Estimates on when a CRQC will be available range from 2028 to 2040. |

@SamWilsn Thank you for the feedback. We are still committed to make the Ethereum ecosystem quantum safe. As to the issue of Intellectual Property, we are still exploring options. |
Agree with suggested change. Co-authored-by: Sam Wilson <57262657+SamWilsn@users.noreply.github.com>

As decided in ethcatherders/EIPIP#362, we are unable to merge this pull request. If you are able to grant a patent license, you may open a new pull request and keep the same proposal number. |
Proposal to enhance the digital signing system for Ethereum to include a quantum-safe proof-of-knowledge (QSPoK) to ensure that the security of the transactions cannot be compromised by a quantum computer. Backward-compatibility is achieved by only introducing minimal changes to the existing implementations of Ethereum validators and clients.
QSPoK implementations include Zero-Knowledge Scalable Transparent Argument of Knowledge (zkSTARK) or MPC-in-the-Head (MPCitH).
