To conclude an intense week which enshrined privacy in Ethereum with Kohaku wallet (@ncsgy), we hacked at @ethglobal with @RAILGUN_Project . Our FROSTGUN team ended up with 1st Ledger HW integration prize. @_zy0nn @BTChip @SimonMasson2 @RenaudDUBOIS10 - ethglobal.com/showcase/frost…

Joint work with Linea and Alpen Labs to reduce ECC proving time. This is the opportunity to update protocols to bls12-381 without extra proving cost. eprint.iacr.org/2025/933

Privacy, ZKNOX has your back ! Here is the fastest in circuit ECC over Pectra incoming BLS scalar field with implication on RAILGUN like schemes. We are honored to count among us @SimonMasson2, a Bandersnatch designer. Check our latest post : zknox.eth.limo/posts/2025/04/…

Introducing ZKNox - a new venture by cryptography, hardware and security experts @BTChip, @renauddubois10 and @simonmasson2. We plan to accelerate on growing the crypto ecosystem, with a strong focus on defensive technlogies and decentralization.

Congrats to 🎓Dr. Simon Masson (@SimonMasson2) for successfully defending his PhD thesis "Algorithmic of curves in the context of bilinear and post-quantum cryptography"!🍾🎉👏 Thousands of possibilities for your future, as many as the branches of this tree.

So here github.com/isogenies-vdf/… is the sage code for the isogenies VDF eprint.iacr.org/2019/166.pdf. Kudos to @SimonMasson2 ! Feel free to comment/constribute/extend/port to any language! cc @luca_defeo
