How Bitcoin engineers are solving the quantum risk

Tackling the technical battle to protect Bitcoin from quantum computers. We explore why quantum-resistant signatures are up to 100x larger than current ones and the impact this has on block space and fees. From lattice-based math to STARK-based compression, Charlie breaks down the leading proposals like BIP 360 and BIP 347. We also calculate the “migration” timeline—how long it would actually take to move every Bitcoin to a safe address before “Q-Day” arrives.

Notes:

* Quantum signatures can reach 17,000 bytes (500x!)

* Optimized hash signatures are 50x larger.

* Full BTC migration takes 76 to 142 days.

* There are 190 million unspent BTC outputs.
