A report from the Bitcoin Policy Institute reveals that recent research has drastically lowered the expected quantum computing power needed to break Bitcoin's encryption. The theoretical number of qubits required has dropped from an estimated 10 million to less than 500,000, with potential reductions to as few as 10,000 to 26,000 qubits. Although current quantum technology has not yet reached this level, Bitcoin developers are actively working on defense mechanisms. The anti-quantum proposal BIP-360 began testnet trials in March, and the Taproot upgrade, activated in 2021, has reserved an upgrade path for quantum-resistant verification. The report emphasizes that Bitcoin's quantum threat is not insurmountable, with technological preparations steadily advancing.
