Project Eleven Develops Quantum Recovery Tool for Bitcoin, Excludes Satoshi’s Coins

Project Eleven Introduces Quantum Recovery Tool

Project Eleven has launched a new zero-knowledge proof system to address the challenges posed by quantum computing on bitcoin security. This tool is designed to recover Bitcoins that are at risk due to quantum vulnerabilities proposed in Bitcoin Improvement Proposal 361 (BIP-361).

Understanding BIP-361

BIP-361, formulated by Jameson Lopp and five co-authors, aims to freeze bitcoin addresses that are vulnerable to quantum attacks. The proposal suggests halting new deposits to these addresses after three years and locking away the remaining coins after five years. Notably, this includes approximately 1.1 million BTC belonging to Bitcoin’s pseudonymous creator Satoshi Nakamoto.

Zero-Knowledge Proofs Explained

The use of zero-knowledge proofs allows users to demonstrate ownership of a wallet’s key material linked to a specific address without disclosing any of the key information itself. This method ensures that, even in the post-Q-Day scenario – when quantum computers could create signatures indistinguishable from legitimate owners – users can still prove ownership.

Performance Benchmarks

The performance metrics of Project Eleven’s proof system are notable. On an M5 MacBook Air, generating a proof takes approximately 243 milliseconds, while verification requires about 40 milliseconds. This solution is achieved without utilizing a GPU, demonstrating efficiency in processing speed.

The Challenges of Satoshi’s Coins

Despite the innovative recovery approach, Satoshi’s BTC remains inaccessible through this method. The underlying technology relies on a structure established by BIP-32, which organizes wallet keys in a tree format. Coins mined by Satoshi used a different method, lacking a hierarchical structure, thus rendering the zero-knowledge recovery technique ineffective for these specific funds.

Future Implications

The advancement presented by Project Eleven introduces a feasible way to recover bitcoin at risk due to quantum vulnerabilities. However, it highlights a significant limitation regarding the coins attributable to Satoshi, which are essentially trapped and unable to be recovered under the current protocol standards.
