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.

Trump\'s quantum push renews bitcoin security fears over 7 million BTC exposure

The United States is bringing forward to 2031 a federal deadline to shift to quantum-resistant cryptography and is pushing quantum computer development as a national task, reviving concerns about bitcoin security. About 7 million bitcoins with already exposed public keys are seen as potential targets for future quantum computers, with more than 70 percent linked to repeated address use. Some analysts say the near-term threat remains limited, but the pace of migration is a key challenge.

Bitcoin quantum transition focuses on \'abandoned assets\' as Coinbase proposes three-step response

Coinbase has suggested a compromise for handling bitcoin left unmoved during a shift to quantum-resistant addresses, after estimating that as many as about 7 million BTC could be vulnerable to quantum attacks. An independent advisory report said adding quantum-resistant signatures is a solvable technical task, but the main issue is how to treat assets not transferred by a deadline. It outlined three measures, including throttling transfers from older addresses and phased retirement of legacy schemes.
