🚨 Ethereum has five potential vulnerabilities to quantum attacks that Bitcoin does not have, according to a study by Google Quantum AI:

🔍 The first vulnerability is its persistent account model: once used, the public key remains permanently exposed, allowing the largest accounts to be compromised within a few days.

⚠️ The second affects smart contracts: their fixed administrative keys, exposed on-chain, can be stolen, compromising stablecoins and real-world assets worth over $200 billion.

🤝 The third vulnerability lies in the PoS consensus and the BLS signatures of nearly one million validators, putting more than 38 million ETH in staking at risk.

🧾 The fourth and fifth vulnerabilities threaten data availability through the KZG scheme and smart contract code lacking post-quantum primitives, affecting billions more in total value.
