Moody\'s says bitcoin quantum response deadline is 2030

Global credit rating agency Moody\'s warned that responding to quantum computing is no longer a long-term task for bitcoin and the digital asset industry. It said U.S. executive orders signed by President Donald Trump increased pressure on the crypto industry to show it can defend core cryptography, bringing forward federal post-quantum migration goals from 2035 to 2030-2031. Moody\'s said quantum-capable attacks could undermine public-key cryptography and make losses hard to reverse in on-chain transactions.

Big banks expand bitcoin custody vaults, but key issue turns to quantum computers

Global big banks are expanding bitcoin custody as a strategic business, but a report warns today’s crypto custody infrastructure could face structural risks in a future quantum-computing era. Swiss digital asset technology company Taurus said major custodians carry significant risk during a shift to quantum-resistant cryptography. It said upgrades require blockchain protocol changes and broad coordination. The report argues MPC may face bigger hurdles than HSM, though the view is contested.

Ethereum unveils quantum-computing plan costing $0.07 per account

A plan has been presented for Ethereum to prepare post-quantum security at the account level without a network-wide upgrade. Nico (니코), head of the Ethereum Foundation privacy project Kohaku, said the structure could be implemented at a cost of about $0.07 per account. The proposal seeks to verify quantum-resistant signatures on Ethereum’s execution layer without a hard fork or added precompiles, and includes formal verification steps. Further security audits are planned.
