Bitcoin Quantum(@btc_quantum):Google demonstrated a circuit for breaking the ECDSA and ECC signatures that secure blockchains, grounded the analysis in Bitcoin’s own attack model, and in doing so made the risk to crypto assets concrete and plausibly near-term rather than theoretical. It remains, importantly, an engineering problem the field knows how to solve and it is the problem Bitcoin Quantum is built to answer, with a quantum-safe Bitcoin and post-quantum settlement designed for exactly this threat.
