StarkWare Says it Confirmed a Quantum Safe Bitcoin Transaction on Mainnet

StarkWare reported it successfully confirmed a "quantum-safe" Bitcoin transaction on mainnet, presenting a proof-of-concept that a transaction signed with post-quantum cryptography can be accepted on-chain. The demonstration shows a viable technical path for creating Bitcoin transactions resistant to known quantum attacks. However, this single implementation does not constitute a network-wide mitigation: durable protection will require vetted post-quantum standards, broad wallet and infrastructure support, and coordinated adoption. Until those steps occur, the result is an important milestone but not a near-term elimination of Bitcoin's quantum risk.
