GM 🤯Google: Quantum computers may hack Bitcoin sooner than expected. • The attack will require less than 500,000 qubits (previously we talked about millions). • It will take about 9 minutes for a quantum computer to crack a transaction. • It is faster than confirming a transaction on the BTC network. The probability of successful interception is about 41%. • How it works: At the moment of sending BTC, the public key is temporarily disclosed. The quantum computer uses this time to calculate the private key and redirect the funds before the transaction is confirmed. Some of the calculations are performed in advance, and the final "hacking" occurs at the time of sending. • What is already at risk: Approximately 6.9 million BTC (almost a third of the total supply) may be vulnerable. This includes about 1.7 million BTC mined in the early years, and any wallets with address reuse.
