How can a single reused random number lead to the total loss of your Bitcoin private key?⚡️
Last week, we explored the Schnorr Proof of Knowledge. Today, we move from theory to practice and see how that interactive protocol becomes a non-interactive digital signature scheme.
Join the Cryptographic Foundations of Bitcoin club, every Thursday at 8 PM, with host Kartikeya Sharma.
We’ll cover:
🔹 Schnorr Interactive Proof: Proving ownership of a secret without revealing it
🔹 Fiat-Shamir Transform: How hashing removes the need for interaction
🔹 Nonce Reuse Catastrophe: How poor randomness can expose a private key
📍 8 PM only on Discord:
