Cardano Surpasses Ethereum in Quantum Resistance

A recent report by Google's Quantum AI team has shed light on the quantum resistance of various cryptocurrencies, including Cardano and Ethereum. According to the study, Cardano's UTXO design provides stronger protection against future quantum attacks, earning it a spot in the second-best tier for quantum resistance.

The research highlighted that account-based systems like Ethereum expose public keys early, making them vulnerable to quantum machines. In contrast, Cardano's UTXO architecture allows better control over transaction exposure, reducing the risk of key exposure.

Meanwhile, the study revealed that around 20.5 million ETH are already exposed and at risk of being compromised by a powerful quantum computer. Ethereum developers have started a response plan, including a post-quantum research portal launched in March and a full upgrade targeting completion by 2029.
