How to Sign and Verify a Lamport Signature

🐚 Bitcoin arriva alla SAA @gianlucacpl — Project Manager di Lab in BitPolito — e il nostro Presidente, @bitciccio, introdurranno Bitcoin agli studenti della School of Management di Torino. In un’unica lezione, parleranno della storia della moneta, della nascita di Bitcoin e delle sue implicazioni sociali ed economiche, coprendo anche qualche fondamento tecnico. La discussione verrà portata avanti insieme a M. Giulia Salvadori — professoressa associata di Diritto Privato in UniTo — e Fabio Trolli — avvocato e dottore di ricerca in Diritto Civile. Ci vediamo il 21.04 dalle 9:00 alle 11:00, nell’Aula Magna in via Ventimiglia 115, Torino. Ti aspettiamo!

I've been working on a post-quantum cryptography registry/wiki and it's now live. If you're an engineer trying to evaluate PQC algorithms side by side, you have to piece together information from FIPS documents, ePrint papers, mailing list threads, and scattered READMEs. There are some existing resources out there for parameter sets but I wanted something that goes much further and includes everything; algorithm descriptions, use case and feature filtering, benchmarks, implementation references, and wiki-style prose all in one place with a consistent schema. So that's what this is. It covers nine algorithms today; the NIST standards (ML-KEM, ML-DSA, SLH-DSA), the NIST pipeline (FN-DSA, HQC), blockchain-specific schemes (SHRINCS, SHRIMPS, leanSig), and XMSS. There are a lot more I want to add and the registry is open source so contributions are welcome.

How fragile is a centralized fiat system? 🏦

We are proud to announce we have won First Place @CypherTank securing a guaranteed $250K pre-seed investment to scale what we’ve built and build what’s next. For us this isn't about a trophy. It's about something bigger: Bitcoin being ready for its universal trading layer.

BREAKING: We've finally figured out what animals are saying. This is next-level insanity.

Schnorr signatures: Rogue key attack explained

We did it. Kaleidoswap executed the first RGB asset swap on Lightning mainnet. No testnet. Not a demo. For the first time, an RGB20 stablecoin (tUSDT) was swapped trustlessly on Lightning, live on Bitcoin. Full technical breakdown: kaleidoswap.medium.com/-the-first-eve…
