Wu Shuo learned that, according to a report from the Bitcoin Policy Institute, the latest research significantly reduces the expected computational power needed for quantum computers to crack Bitcoin encryption. The theoretically required number of quantum bits has dropped from an initial estimate of 10 million to less than 500k, and could even be reduced to between 10k and 26k.

Although quantum technology has not yet reached this level, Bitcoin developers are actively building defenses. Among them, the anti-quantum proposal BIP-360 testnet was launched for testing in March this year, and the previous Taproot (a major Bitcoin upgrade activated in 2021) architecture has also reserved an upgrade path for quantum resistance verification. The report indicates that the quantum threat to Bitcoin is not insurmountable, and related technological reserves are steadily advancing.
