Bitcoin gets its first working prototype of quantum-resistant wallet rescue tool

Lightning Labs CTO Olaoluwa Osuntokun demos a prototype that could prevent millions of wallets from being frozen under a future quantum-defense upgrade What to know : Olaoluwa “Roasbeef” Osuntokun, chief technology officer at Lightning Labs, has built a prototype tool meant to rescue ordinary Bitcoin wallets if the network ever activates an emergency quantum-defense upgrade. The system would let users of vulnerable Taproot and other modern wallets prove they created a wallet using its secret seed, without revealing that seed, providing a backup way to access funds if traditional digital signatures are disabled. While the prototype works today and addresses a long-standing gap in Bitcoin’s quantum contingency plans, it has no formal path to adoption yet, and developers remain split on how urgent the quantum threat really is.
