StarkWare CEO Eli Ben-Sasson says Bitcoin needs a soft fork for quantum resistance
- —StarkWare executed the first quantum-safe Bitcoin transaction of 10,000 satoshis in block 964,199
- —QSB protects only new outputs, leaving already-exposed public keys vulnerable to quantum attacks
- —QSB transactions are non-standard and require direct miner cooperation to be included in blocks
- —A September 2026 optimization cut QSB preparation costs by about 79%, from $320 to $67
Why it matters: Quantum risk affects all Bitcoin wallets with exposed keys, but without a soft fork protection remains partial and dependent on miners.
