Quantum computing poses future risks to blockchain security; Bitcoin and Ethereum plan defenses.

European financial regulators warn that advancing quantum computing could threaten blockchain cryptography protecting Bitcoin, Ethereum, and other systems. Though no current quantum computer can break these encryptions, Google's new research lowers the estimated quantum power needed to do so, raising urgency. Bitcoin developers propose phased upgrades to eliminate vulnerable signature schemes, while Ethereum aims for full quantum resistance by December 2029. These efforts focus on proactive preparation to secure cryptocurrency networks before powerful quantum machines emerge.

Quantum computing's emerging threat to Bitcoin security is the focus here, with Pluang's market snapshot as of Sep 23, 2026 21:02 WIB showing that out of 50 major cryptocurrencies, 27 rose and 22 fell. Notable movers include LINK at Rp226.156 with a 1-day change of -3.92% and a typical hold time of 63 days, CRV at Rp6.275 down 3.92% with a 61-day hold, and AXS at Rp20.175 up 3.90% with a 62-day hold and a Pluang order activity heavily skewed to selling at 97%.
