BitcoinEU regulators warn quantum computers could derive private keys and expose ~6.9M bitcoins, and Eigen Labs research cuts attack resource needs by over 50%.
The European Banking Authority, the European Insurance and Occupational Pensions Authority, and the European Securities and Markets Authority published a joint risk report on September 23, warning that quantum computers pose a serious risk to the cryptography protecting communications, transactions, databases, and blockchains. They said the threat could materialize sooner than the commercialization of quantum technology, and called on financial institutions and market participants to prepare for the rapid development of quantum computers. In crypto assets, ownership is proven through digital signatures using public and private keys, but future quantum computers could derive a private key from a public key and impersonate the owner to move assets. CoinDesk, citing data from CryptoQuant, reported that roughly 6.9 million bitcoins could be exposed to quantum attacks. The EU has already set out a plan to migrate to post-quantum cryptography, asking member states to begin the transition by the end of 2026 and aiming to protect high-risk sectors by the end of 2030 at the latest. On September 10, Eigen Labs published research showing that the key computational processing required for a quantum attack on the cryptography used by Bitcoin and Ethereum could be reduced by more than 50 percent in resource terms compared with previous estimates.

EthereumEigen Labs research shows quantum attacks on Ethereum's cryptography could require over 50% fewer resources, heightening the threat to its digital signatures.
Eigen Labs is mentioned only for publishing research on reduced quantum-attack resources, with no clear positive or negative impact on the firm itself.
