What’s going on with Bitcoin this time? Adam Back breaks down where Bitcoin stands today — and what he would actually change in Bitcoin’s code.

At Proof of Talk in Paris, he explains why Bitcoin’s base layer is designed to remain stable, how the network has already been optimized and rewritten multiple times, and why Layer 2 protocols like Lightning may become the default for mobile wallets.

Back also discusses sidechains, additional blocks, privacy upgrades, signature aggregation, and the long-term question of quantum computing. If Bitcoin ever needs to adapt to new cryptographic threats, what should change — and what should never be touched?
