The Byzantine Fault: A Tale of Trust, Treachery, and Triumph in Technology and Blockchain
Imagine a circle of medieval generals, their torches flickering in the night, encamped around a formidable enemy fortress. Each general commands a division of the Byzantine army, and their mission is clear: attack or retreat, but only in unison. A single misstep—attacking when others retreat, or vice versa—spells doom. The catch? Some generals are traitors,… Read more

Unlocking the Future of Secure Signatures: SPHINCS+ and Stateless Hash-Based Cryptography
Digital cryptography is the backbone of secure communication in the modern world. At its core, cryptography relies on mathematical functions that are easy to compute in one direction but difficult to reverse. One such fundamental tool is the cryptographic hash function, which transforms input data into a fixed-size string, known as a hash, that appears random… Read more
