Key facts
- Roughly 6.04 million Bitcoin, about 30% of supply, are exposed to quantum computing threats.
- The Quantum Alliance will focus on four groups: migration, zero-knowledge systems, wallet security, and cross-chain compatibility.
- The alliance is modeled on the Internet Engineering Task Force and will publish its work openly.
Nine blockchain organizations have launched the Quantum Alliance, an open standards body aimed at defining and verifying what it means for crypto networks to be "quantum-ready." The group warns that approximately 6.04 million Bitcoin, representing about 30% of the total supply, are vulnerable to quantum computer attacks due to current elliptic-curve signature cryptography. Forecasts suggest such threats could materialize in the late 2020s, with some models pointing to early 2028. The alliance, modeled after the Internet Engineering Task Force, will work in four groups: blockchain migration, post-quantum zero-knowledge systems, wallet security, and cross-chain compatibility. Its proposals will be based on public evidence and working implementations, with all outputs published openly. The initiative addresses the lack of a standardized definition and testing method for quantum-resistance in the crypto space, a risk that affects not only Bitcoin but also stablecoin keys, bridges, oracles, and governance contracts.
