Missed @btcplusplus Seoul Privacy Edition, but these Fedimint stats speak volumes.
3 years. 80 federations. 463K transactions. 24K wallets holding ecash notes.
Incredible to see how far Fedimint has come. Huge respect to everyone building, contributing, and growing this ecosystem. The work speaks for itself. 🔥

Nifty (@niftynei) announces @btcplusplus Eindhoven, April 2027: cryptography edition.
Held in Brabant, the historic region that gave the world AES and SHA-3.

Someone built a silent payment frostsnap flow with e2e encryption between parties 👀
Congratulations to BlackIce: Distributed Frost Silent Payments for taking home 1st place in our privacy focused hackathon at @btcplusplus in South Korea today 🏆
"Silent Payments has suffered from the lack of multisig & hardware wallet support. We built payments using FROST / Frostsnap hardware that enable distributed signing coordinated using Marmot."

Taking home the bronze in 3rd was the Kakaonut project, by Cashu team member @eriklocalhost 🥜

평문으로 노출되는 라이트닝 메모를 암호화하여 보호하는 프로토콜을 @btcplusplus 에서 소개할 수 있었습니다!
아크, 페디, 이캐시등 L2 전반에 적용 가능합니다.
빠른 시일내에 poc와 proposal을 게시할게요!
@JIN_1337 is solving Lightning memo privacy !
Metadata in a lightning payment memo can leak info through to your service provider, such as an ecash mint, Ark server, etc.
His system encrypts the plaintext note in the existing field. Gateway sees ciphertext. You stay private.

Closing panel introductions:
Dan Gould announces Payjoin on the @BULLBITCOIN_ exchange. He clarifies he did not invent Payjoin (just a maintainer)!
Markus gives the latest Shielded Bitcoin updates from @allocinitxyz
Elsirion shouts out @notgrubles as a pioneer of Federated Ecash circa 2015! Grubles made a proposal that predates Fedimint by 6 years.
Waxwing clarifies he invented the name “JoinMarket”, but credits Chris Belcher with the project itself. He sees the the future of Bitcoin privacy as “off-chain”.
