Bitcoin Quantum Computing Risk Manageable, Experts Say

A new report from investment firm Bernstein has shed light on the potential risks posed by quantum computing to Bitcoin's security. According to the report, the threat is not existential and can be managed as a long-term upgrade cycle for the network.

One of the key concerns raised by the report is that 1.7 million BTC stored in legacy wallets from the early days of Bitcoin are at risk due to their exposure to public keys on the blockchain. This makes them vulnerable to 'harvest now, decrypt later' attacks, which could compromise the security of these funds.

However, experts believe that this threat can be mitigated by implementing quantum-resistant cryptography and migrating user keys to secure formats. Blockstream CEO Adam Back noted that current quantum computers are extremely basic and lack the necessary hardware improvements to break Bitcoin's cryptography.
