New research from Alice & Bob demonstrates that fault-tolerant cat-qubit hardware could break RSA-2048 encryption with a record-low number of physical qubits. The study highlights the accelerating timeline for quantum threats to classical cryptography and the necessity of transitioning to post-quantum standards.

New research reveals that the smaller key sizes used in blockchain elliptic curve cryptography make them uniquely vulnerable to quantum computing attacks. This threat extends from individual cryptocurrency wallets to systemic risks involving cross-chain bridges and real-world asset tokenization.

This edition of the Bitcoin Optech newsletter explores critical upgrades for post-quantum resistance in P2P protocols and the Lightning Network. It also covers new proposals for miniscript wallet standardization and advancements in CTV-based vault implementations.
