Citibank stated that breakthroughs in quantum computing technology are accelerating, shortening the timeline for security risks to cryptocurrency and internet infrastructure, with Bitcoin facing particularly significant risks. Citi analysts pointed out that Bitcoin, due to its relatively conservative governance mechanism and slower protocol upgrade pace, is more vulnerable when it comes to quantum-resistant upgrades. Currently, approximately 6.5 to 6.9 million BTC are at potential risk of quantum attacks due to exposed public keys, accounting for about one-third of the circulating supply. The report also mentioned that PoS networks like Ethereum might be more adaptable to quantum-resistant cryptographic solutions due to their flexibility in protocol upgrades, but validator keys still face potential risks. Citi also noted that the industry is still expected to adapt through post-quantum cryptography and protocol restructuring.
