Elliptic Curve Cryptography (ECC)

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.

Galaxy Digital is investing $5 million into a multi-pillar initiative to protect the Bitcoin network from quantum computing attacks. The program focuses on developer grants, academic research, and advisory leadership to prepare for the eventual arrival of cryptographically relevant quantum computers.

Researchers at Google recently discovered a way to break 256-bit ECC encryption with much lower qubit counts than expected, but withheld their exact method using zero-knowledge proofs. The startup Eigen Labs successfully bypassed this secrecy by using AI agents and crowdsourcing to develop an even more efficient attack circuit.
