Tom Lee warns 35 percent of bitcoin supply could be exposed to quantum threat within 3 years

A warning has emerged that about 30 to 35 percent of bitcoin’s total supply could be exposed to quantum-computer attacks in 2028 to 2029. Fundstrat co-founder and Bitmine chairman Tom Lee said quantum computing could undermine bitcoin’s existing security system. He said the crypto industry has no unified response, while the Ethereum and Solana ecosystems are better prepared. Adam Back disputed Lee’s technical claims, saying bitcoin ownership is protected by ECDSA digital signatures and seed-phrase entropy.

AI adds new variable to Bitcoin\'s post-quantum shift after Anthropic research sparks security debate

Artificial intelligence has emerged as a new variable in talks on moving Bitcoin to quantum-resistant security, after an Anthropic frontier AI model found a new way to attack a weakened version of AES. Anthropic said the AI-made method sped up cracking by 200 to 1,000 times and also devised an improved attack on the post-quantum signature scheme HAWK. Researchers and industry figures say the work does not pose an immediate threat but highlights the need to assess AI-driven cryptanalysis alongside quantum risks.

Satoshi\'s 16-year-old quantum plan forms backbone of Bitcoin BIP-360 and BIP-361

Bitcoin discussions on responding to quantum computers are elevating a design proposed 16 years ago by Satoshi Nakamoto into the basis for formal proposals, including BIP-360 and BIP-361. Developers are testing a method to force cryptographic changes by setting a cutoff at a specific block height. The plan targets exposed ECDSA public keys, but could raise fees by increasing transaction data size and would permanently isolate lost early coins that cannot be migrated.
