#antiquantumbitcointransactionminedonmainnet 🚨 BITCOIN JUST TOOK ITS FIRST STEP TOWARD QUANTUM-SAFE SECURITY! ⚛️🛡️
A researcher from StarkWare has reportedly completed the first quantum-safe Bitcoin transaction on mainnet.
The transaction was confirmed in block 964,199, using the Quantum-Safe Bitcoin (QSB) scheme — without requiring a soft fork, hard fork or consensus change.
🧠 Why it matters:
QSB replaces vulnerable elliptic-curve signatures with hash-based, quantum-resistant security, designed to protect transactions against future quantum attacks.
But there are still major limitations. 👀
⚠️ It reportedly requires hours of GPU computation and costs roughly $150–$200 per transaction.
🚫 QSB transactions are currently non-standard under Bitcoin Core relay rules.
🎯 It protects specific transactions, not the entire Bitcoin network.
The bigger takeaway? Bitcoin now has a real-world demonstration of a potential quantum-resistant path while developers continue working toward longer-term protocol solutions.
⏳ Quantum computing may still be years away — but Bitcoin's defense has already started.
