First quantum-safe Bitcoin spend mined on Starknet method
StarkWare has mined what it calls the first quantum-safe Bitcoin spend, sending 3.1 BTC with a method described by StarkWare researcher Avihu (avihu28)—a spend no quantum computer could forge under Bitcoin's existing rules. The Block independently confirmed the milestone as the first quantum-resistant Bitcoin transaction, citing StarkWare. StarkWare has since published details of the mainnet demonstration and a talk by @thedamooo at Bitcoin Asia explaining the approach.
- Uses a quantum-safe signature approach built around StarkWare's research, rooted in the hash-based cryptography Starknet itself is built on.
- QSB is opt-in and works under Bitcoin's existing rules, protecting coins prepared in advance.
- Starknet frames the real quantum risk to Bitcoin as paralysis rather than theft—a break would strand large holdings—so QSB gives custodians a spend path they can provision now, without waiting on a soft fork or anyone else's timeline.
- Serves as a proof-of-concept for making Bitcoin transactions resilient to future quantum computing.

- This came from the people who build Starknet, and that's no accident. Hash-based cryptography isn't a technique picked up for this paper, it's the material Starknet has been made of from the start.
