Regulators in the EU have recently issued an official warning that quantum computing could potentially break the current encryption systems used in blockchain. The warning explicitly highlighted the urgency of the anti-quantum upgrades for the two major public chains, BTC and ETH. At present, the Bitcoin developer team is assessing a draft proposal for an anti-quantum migration, while Ethereum has set the target nodes for its anti-quantum upgrade in 2029. Previously, the market generally viewed anti-quantum measures as a forward-looking technical topic more than five years away. The formal regulatory warning suggests that compliance requirements will be enforced earlier, pushing public chains to implement the relevant changes. In the short term, it may not directly threaten the security of existing on-chain assets, but it will reshape market pricing expectations regarding the long-term security margin of public chains. This signal also implies that future compliance entry thresholds for public chains will add an anti-quantum security dimension, and technical preparation advantages held by leading projects will become even more pronounced. $BTC $ETH #加密监管 #抗量子升级 #on-chain data
