BTC cracked within two years? The king of SPAC warns that the "Google quantum chip" can kill sha-256 in seconds; Adam Back curses at the nonsense

Will quantum computing crack BTC? Recently, it has caused a heated discussion in the BTC community. Well-known venture capitalist Chamath Palihapitiya recently warned that the SHA-256 algorithm used by BTC could be cracked with just 8000 Google quantum chips. However, BTC legend Adam Back rebutted this statement. (Background: BTC wallet may be cracked by Google quantum chips' brute force attack? Cosine: Worried about Satoshi's Private Key decades later) Google announced on the 9th its newly developed next-generation chip Willow, which has successfully overcome the key challenge of quantum computing. The chip can perform calculations with 105 qubits, solving a problem that traditional computers would take 1 billion years to solve in just 5 minutes. Regarding the threat of quantum computing, Ava Labs founder Emin Gün Sirer recently warned that Satoshi's 1 million BTC, which uses the early Pay-to-Public-Key (P2PK) format, exposes the Public Key directly, giving quantum computing attackers ample time to crack it. To prevent the threat, it is suggested to consider freezing Satoshi's BTC. Can 8000 Willow chips crack BTC? Renowned venture capitalist and Social Capital founder and CEO Chamath Palihapitiya recently stated on the ALL IN Podcast that about 8000 Willow chips could crack the SHA-256 algorithm used for BTC. The time for blockchain to implement a new hashing algorithm may be only 2 to 5 years. However, BTC legend and Blockstream founder and CEO Adam Back refuted this statement, saying, "No, you can't increase the number of qubits by connecting a large number of 105-qubit chips. We are far from achieving a computer with 1 million qubits in this decade, and very likely in the next decade as well." Ledger CTO Charles Guillemet also said, "That's embarrassing. There are so many wrong takes: - There's no encryption in Bitcoin - Quantum computers don't break SHA-256 - 2 Willow chips of 105-qubits don't make a 210-qubits chip." Bubbl.fm founder Kaz added that SHA-256 is not threatened by quantum computing, as the hash function is one-way and irreversible, which quantum computers cannot crack. Quantum computers pose a threat to encryption algorithms, such as the Schnorr signature algorithm, which may face risks in 20 years. In response to community doubts, Chamath Palihapitiya explained that his remarks were misconstrued, and he clarified that quantum computing will pose a threat to v1 encryption methods. Although the specific timeframe is unclear, it is certain that this will not happen in the short term. However, Chamath Palihapitiya cautioned that while any potential risks of BTC can be addressed through a fork and the implementation of anti-quantum encryption technology for new transactions, it cannot protect the exposed and un-migrated Public Keys retroactively, such as the funds in early p2pk addresses, which are still vulnerable to quantum computing attacks against ECDSA (Elliptic Curve Digital Signature Algorithm) and will become targets of attack. Chamath Palihapitiya also cited a 2010 article by Satoshi, in which he stated that SHA-256 is very powerful and can continue for several decades unless there is a major breakthrough attack. If it is cracked, the blockchain can reach consensus, lock in the state before the crack, and transition to a new hash algorithm.
