Blockchains Quietly Prepare for Quantum Threat as Bitcoin Debates Timeline

Quantum computers still cannot break Bitcoin, but several major blockchains are preparing for a future in which they might.

In the past week, Aptos proposed post-quantum signature support as Solana tested quantum-resistant transactions. Meanwhile, parts of the Bitcoin community renewed calls to accelerate work on quantum-safe upgrades.

These developments point to a growing anxiety across crypto. Investors argue that dismissal of quantum risk by influential voices is weighing on Bitcoin’s (BTC) price, which has dropped 24% over the past three months.
