Die nächste große Bedrohung für Krypto? Quantencomputer könnten Bitcoin bis 2029 knacken

Neue Fortschritte im Quantencomputing drängen Krypto-Unternehmen dazu, sich auf eine potenzielle Sicherheitsherausforderung vorzubereiten, die die Branche verändern könnte.

Der Kryptowährungssektor verstärkt seine Bemühungen, Blockchains und digitale Wallets vor zukünftigen Angriffen durch Quantencomputer zu schützen. Neue Forschungsergebnisse von Google deuten darauf hin, dass leistungsstarke Quantenmaschinen aktuelle Verschlüsselungsmethoden früher als erwartet knacken könnten, was auf dem 2 Billionen Dollar schweren Kryptomarkt Sorgen hervorruft.

Branchenvertreter betonen, dass die Bedrohung noch Jahre entfernt ist, die Vorbereitungen jedoch bereits laufen.

Wichtige Details

Google schätzt, dass Quantencomputer, die in der Lage sind, die heutige Verschlüsselung zu knacken, bis 2029 einsatzbereit sein könnten – früher als in früheren Prognosen angenommen, die von mindestens einem Jahrzehnt ausgingen.

Die meisten Blockchains, einschließlich Bitcoin und Ethereum, verlassen sich auf jahrzehntealte Kryptografie, um Transaktionen zu sichern. Experten warnen davor, dass ein ausreichend fortschrittlicher Quantencomputer private Schlüssel aus öffentlichen ableiten könnte, was es Hackern ermöglichen würde, Gelder zu stehlen und betrügerische Transaktionen zu autorisieren.

Bitcoin gilt aufgrund seiner langen Transaktionshistorie und der großen Anzahl sichtbarer öffentlicher Schlüssel als besonders gefährdet. Untersuchungen legen nahe, dass rund 35 % des im Umlauf befindlichen Bitcoin-Bestands anfällig sein könnten, während einige Studien diese Zahl eher bei 50 % ansiedeln.

Große Blockchain-Netzwerke müssen erst noch quantenresistente Verschlüsselungen implementieren. Die Ethereum Foundation strebt einen vollständigen Schutz bis 2029 an, während die Algorand Foundation plant, noch in diesem Jahr quantensichere Konten einzuführen.

Marktreaktion

Das wachsende Risiko hat bereits die Anlegerstimmung beeinflusst. Jefferies hat Anfang des Jahres eine 10%ige Bitcoin-Allokation aus seinem Modellportfolio entfernt und dies mit der langfristigen Bedrohung durch das Quantencomputing begründet.

Warum es wichtig ist

Ein erfolgreicher Quantenangriff auf eine große Kryptowährung könnte massive Verkäufe auslösen, das Vertrauen beschädigen und Schockwellen durch die Märkte für digitale Vermögenswerte senden.

Die Kryptoindustrie hat noch Zeit, sich vorzubereiten, aber das Rennen um die Modernisierung der Blockchain-Sicherheit hat begonnen. Händler werden genau beobachten, ob die Entwickler schnell genug handeln können, bevor das Quantencomputing einen Wendepunkt erreicht.
