Post-quantum signatures built from hash functions. No elliptic curves. No math tricks. Just... hashes.
Let’s break it down visually 👇
🧾 Step-by-Step Walkthrough🧾 Step-by-Step Walkthrough
1. We want to sign a 256-bit message
2. Generate 256 pairs of secret random numbers
3. Hash each secret to get the public key
4. Hash the message
5. Reveal secrets depending on message bits
6. The revealed secrets form the signature
✅ How to Verify✅ How to Verify
1. Hash each revealed secret
2. Compare with the public key
3. If all match, it's valid

In layman's terms, its like comparing 1 hash against 256 hashes?
Burn or steal?
Steal!
Lamport signatures are a quantum-resistant digital signature scheme based on hash functions. They use a pair of secret keys for signing and verification, providing security against quantum attacks. Visual explanations often use diagrams to illustrate key generation, signing, and verification processes, making complex concepts more accessible and easier to understand.
