Overview
- BTQ says the Bitcoin fork replaces ECDSA with a post‑quantum signature scheme aligned with NIST standards, enabling end‑to‑end migration experiments.
- The testnet is open‑source and permissionless, inviting developers, miners, researchers, and users to evaluate quantum‑safe transaction flows.
- Coverage cites more than 6 million BTC tied to revealed public keys as potentially exposed in the future, underscoring the focus on signatures over other risks.
- Reports note substantial trade‑offs, with post‑quantum signatures described as more than 200 times larger, which could slow throughput and raise fees.
- Markets treated the move as preparatory rather than urgent, with Bitcoin up about 1.5% and BTQ’s shares reported higher following the announcement.
