AmericanFortress has unveiled a post-quantum signature scheme aimed at safeguarding existing crypto assets, including “dormant” wallets from the Satoshi era containing 1.1 million BTC, as reported by CoinDesk<\/a>. <\/p>\n

The protocol involves a backward-compatible soft fork<\/span> and the use of zero-knowledge proofs<\/a>. According to the developers, this mechanism will allow for the freezing and protection of vulnerable old-type Bitcoin addresses without the need for mass fund migration.<\/p>\n

This primarily concerns BIP-32<\/a> addresses, including wallets associated with Satoshi Nakamoto.<\/p>\n

AmericanFortress believes that once such coins are locked, the network’s governance can decide their future. Options mentioned by the company’s head, Michal Pospieszalski, include transferring, burning, or redistributing the funds.<\/p>\n

The topic gained renewed attention following a recent publication by Google Quantum AI. Researchers stated<\/a> that many blockchains and cryptocurrencies still use ECDLP-256<\/span>, and their assessments are directly applicable to secp256k1\u2014the elliptic curve underpinning Bitcoin and Ethereum.<\/p>\n

Google added that post-quantum cryptography remains one of the most comprehensible paths for the long-term protection of such systems.<\/p>\n

Amidst this, the Bitcoin community is already discussing various network protection options. One of these is BIP-360<\/a>, which proposes a new type of Pay-to-Merkle-Root outputs.<\/p>\n

The initiative’s authors claim that this format retains functionality similar to Taproot<\/a>, but eliminates vulnerability to quantum attacks of the key path spending<\/span> type.<\/p>\n

CoinDesk notes that AmericanFortress’s proposal differs from similar initiatives. The company focuses not on new addresses but on existing and long-inactive wallets.<\/p>\n

According to the developers, this will protect millions of coins without forcing owners to transfer funds.<\/p>\n

In May, AmericanFortress announced raising $8 million to develop quantum-resistant blockchain infrastructure. <\/p>\n

Earlier in May, BNB Chain developers reported<\/a> the results of testing the network’s transition to post-quantum cryptography. The experiment confirmed the blockchain’s theoretical readiness for future threats but revealed a significant performance decrease. <\/p>\n","protected":false},"excerpt":{"rendered":"
