New Protocol Promises Robust Protection for Crypto Assets

A breakthrough in digital security has emerged with a new post-quantum signature protocol by AmericanFortress, aimed at safeguarding substantial cryptocurrency assets from future quantum computing threats. This includes the significant BTC holdings attributed to Satoshi Nakamoto and nearly 5 million other idle Bitcoins.

What Does This Mean for Individual Crypto Holders?

AmericanFortress CEO Michal Pospieszalski assured that crypto holders need not mass transfer their holdings to avoid future risks. The solution proposes a backward-compatible “soft fork,” allowing users to secure their assets with a straightforward update to node and wallet software.

Currently, older Bitcoin addresses classified as “Pre-BIP32” lack a mnemonic security feature and remain critical points of vulnerability. The innovative protocol offers to freeze these legacy wallets, rendering them immune to potential quantum threats.

Michal Pospieszalski elucidated, “Our quantum-resistant protocol ensures automatic protection of funds; post-‘Q-day,’ the community can then decide their fate.”

Additionally, the protocol can be applied to major blockchains beyond Bitcoin, including Ethereum, Solana, and Tron, which expands its protective reach significantly.

How Does the Protocol Ensure Security?

The new system addresses both legacy and contemporary wallet types seamlessly. Unlike traditional mechanisms requiring new chain construction or frequent address rotation, it utilizes zero-knowledge proofs to establish key ownership during transactions, thus fortifying security without burdening system performance.

To achieve this, three distinct mechanisms are at play: raw key security for “Pre-BIP32” wallets, quantum protection for BIP32 compliant addresses, and an innovative scheme called “QBIP32.” Notably, this is accomplished without impacting on-chain efficiency.

The vulnerability of dormant Bitcoins, worth approximately $600 billion, particularly in older segments and specific addresses like Solana’s, underscores the urgency. To address this, AmericanFortress introduced a user-friendly method for adopting quantum security, requiring minimal user interaction and cost.

Industry support and funding are key elements of the project’s current phase. AmericanFortress recently raised $8 million from high-profile investors, including SAVA Digital Asset Fund. Importantly, the company’s findings indicate that while some chains experience slowed performance under quantum testing, their solution operates without such issues.

AmericanFortress plans to make their protocol available for public discussion and demonstration in Paris shortly. The company is actively engaging with blockchain entities to push the boundaries of asset security.

Pospieszalski emphasized, “We are at a critical juncture where robust, quantum-proof protection for BTC and top blockchain networks is now a realizable goal.”
