The post Bitcoin Devs Build Quantum-Proof Wallet Prototype to Protect Funds appeared first on Coinpedia Fintech News
Bitcoin developers have built a working prototype to protect wallets from quantum attacks, allowing users to recover funds even if emergency security changes are activated.Â
The solution addresses risks affecting up to 6.9 million BTC and signals proactive steps toward quantum-resistant Bitcoin security.
Bitcoin: Prototype Designed for Quantum Emergency
A senior Bitcoin developer and Lightning Labs CTO, Olaoluwa Osuntokun, introduced a working prototype that protects wallets from quantum computing threats. The system allows users to recover funds even if Bitcoin disables vulnerable signature mechanisms during a quantum emergency.
The tool uses zk-STARK cryptographic proofs to verify wallet ownership without exposing private keys. This means users could still move funds even if the current signature method becomes unsafe.
The prototype reportedly generates a proof in about 50 seconds on a standard MacBook, uses around 12GB of RAM, and produces a 1.7MB verification proof. Meanwhile, developers say performance could improve further with optimized production code.
Why It Needed: Growing Quantum Computing Threat
Bitcoin wallets rely on elliptic curve cryptography, which is secure against classical computers. However, quantum computers running Shor’s algorithm could theoretically derive private keys from public keys.
Recent research suggests such attacks may be possible faster than previously expected. Around 6.9 million Bitcoin in older and Taproot-style wallets already have exposed public keys, making them potential targets in the future.
To defend against this, developers could deploy an emergency soft fork that disables vulnerable spending paths. But this creates a new problem, many wallets would become unspendable even by their owners.
How Will This Solve Bitcoin Security
The new prototype solves this issue by allowing users to prove ownership through their seed phrase derivation path. This lets them recover funds even if the standard signature method is disabled.
This development reduces the risk of funds being permanently locked during a quantum defense upgrade. It also shows Bitcoin developers are preparing for long-term security threats.
Quantum computers capable of breaking Bitcoin do not exist yet. However, research suggests timelines may be shortening. The new prototype gives the community a working solution before the threat becomes real.
If needed, the system could be integrated into future upgrades, ensuring users can safely migrate funds during a quantum emergency while keeping Bitcoin secure.
