Bitcoin freeze debate grows over coins vulnerable to quantum threats

A debate is growing in the Bitcoin community over whether to restrict spending of coins that could be vulnerable in the era of quantum computers. The dispute goes beyond adopting new cryptography and raises questions about how far ownership rights should be protected and how network security should be ensured. Some developers warn that stolen coins could be sold and hurt trust. Others say forced freezes would undermine core principles by limiting ownership.

Ethereum draws attention for EIP-8141 that allows gas fees without ETH

A new transaction structure has been proposed for Ethereum that would let users pay transaction fees without holding ETH, or allow applications to cover gas fees on their behalf. Ethereum co-founder Vitalik Buterin said development of the Ethereum Improvement Proposal EIP-8141 has made significant progress. The proposal splits transactions into up to 64 frames, enables separation of signing and fee-paying accounts, and aims to expand flexibility while retaining existing wallet structures.

G7 urges rapid preparations for quantum computing threat; bitcoin, ethereum also on alert

A G7 cybersecurity working group urged governments and companies to immediately begin shifting to post-quantum cryptography, warning that technology threatening existing public-key systems is advancing faster than expected. It highlighted the risk of attacks that harvest encrypted data now and decrypt it later. The EU has set timelines for migration. Bitcoin is considering BIP-360, while Ethereum plans broader upgrades. Larger post-quantum signatures could raise storage, bandwidth and transaction costs.
