Lightning Labs CTO unveils first working prototype for Quantum-Resistant Bitcoin Wallet Rescue

Lightning Labs CTO Olaoluwa Osuntokun published a working prototype on April 8, 2026, that enables Bitcoin wallet owners to prove ownership through zero-knowledge proofs without revealing their seed phrase, addressing a critical gap in quantum-defense planning. The tool runs on a consumer MacBook M4 Max, generating verifiable proofs in 55 seconds with 1.7 MB output files, using zk-STARK technology that relies only on quantum-resistant hash functions rather than vulnerable elliptic curves. The prototype solves a theoretical problem: standard BIP-86 Taproot wallets could be permanently frozen if Bitcoin developers deploy an emergency soft fork to disable vulnerable key-spend paths against quantum computer attacks. Osuntokun, a Nigerian immigrant who co-founded Lightning Labs in 2016 and serves as lead developer of the widely-used LND implementation, built the prototype in his spare time by forking TinyGo-to-RISC-V zkVM tools.
