Blockstream's Adam Back Calls Optional Quantum Safeguards
Blockstream's Adam Back Calls Optional Quantum Safeguards
Blockstream's Adam Back calls for optional quantum safeguards, citing preparation as key. Around 6.9 million BTC are vulnerable to quantum attack.
Introduction to Quantum Threats
Google Quantum AI published research showing that quantum computers could break Bitcoin's cryptography with 20 times fewer physical qubits. Adam Back proposed optional quantum-resistance upgrades for Bitcoin.
Quantum Computing Risks
Researchers calculate that approximately 6.9 million BTC are exposed to this vulnerability, of which around 1.7 million correspond to mining rewards from the Satoshi era.
Debate Among Bitcoin Developers
Back's stance contrasts with BIP-361, a proposal drafted by Jameson Lopp and five other developers. This scheme proposes a staged soft hard fork that would freeze coins that fail to migrate to addresses resistant to quantum computing.
Alternative Approaches
- BitMEX Research published an alternative approach proposing the creation of a “Canary Fund” composed of coins vulnerable to quantum attack.
- Other researchers are exploring the possibility of implementing quantum-resistant transactions without the need for a network fork.
Quantum-Resistant Solutions
Outside the Bitcoin ecosystem, networks such as Ethereum, Solana, and Naoris Protocol are also working on quantum-resistance solutions, making “Q-Day” a cross-cutting concern for the entire crypto industry.
Key Takeaways
- Adam Back proposes optional quantum-resistance upgrades for Bitcoin.
- Approximately 6.9 million BTC are vulnerable to quantum attack.
- Alternative approaches, such as the “Canary Fund”, are being explored.
- Quantum-resistance solutions are a concern for the entire crypto industry.
