Hi!!, this is a great initiative and demonstration the community is switching towards the benefits of using post quantum Falcon signatures. Since 2020/2021 we have been exploring the possibility to integrate Falcon in Ethereum. After a series of test, even implementing the feature in solidity we realized a good and feasible approach was to use a precompiled contract. Part of the work was published in Nature Science Journal here and a consolidated core implementation summarized in a EIP proposal we were preparing last year and recently launched. Since this is a similar proposal with a slightly different approach let’s see how we can collaborate so both efforts can converge and have Falcon signatures a reality in ethereum.
We have opened a thread explaining some detailed inputs here
