Here's Satoshi Nakamoto's response on how Bitcoin faces quantum computers

Discussion archives from the BitcoinTalk forum dated July 10, 2010, have resurfaced as a response to the (FUD) spread by Google regarding the threat of quantum computers to Bitcoin and the crypto industry. In the archive, Satoshi Nakamoto emphasized that Bitcoin's SHA-256 algorithm is very strong and can withstand several decades. He explained that if a major threat capable of breaking the code arises, the blockchain network has adaptive defense mechanisms to protect user funds.
Satoshi outlined technical strategies in case of sudden or gradual algorithm failure. If an attack occurs suddenly, the community can agree on the last valid block before the disruption, (lock-in) that block, and continue the network with a new hash function. However, if the threat develops gradually, the software will be programmed to switch to a stronger algorithm at a specific block number. Users only need to update their software to re-sign (re-sign) their assets within the wallet to prevent exploitation.
This visionary explanation from 16 years ago provides a strong contradiction to Google's simulation predicting mass depletion of crypto wallets within days. Satoshi emphasized that Bitcoin software can store new hashes of all old blocks to ensure no fake blocks with old hashes can be used. This proves that Bitcoin's architecture has been designed from the start to evolve and transition algorithms in an orderly manner, ensuring the ecosystem remains secure even in the face of future technological breakthroughs.
