StarkWare tests quantum-resistant Bitcoin transaction on mainnet

StarkWare announced a successful test of a quantum-resistant Bitcoin transaction on mainnet using a post-quantum cryptographic scheme. The test shows that post‑quantum primitives can be encoded and validated within Bitcoin transactions under current transaction mechanics, proving a practical deployment path. While this reduces the immediacy of a quantum threat by demonstrating feasibility, widespread protection will still require standardization, wallet and infrastructure support, and a coordinated migration plan before large-scale quantum computers arrive.
