Bitcoin Bolsters Quantum Defenses as Solana Cuts Inflation

Bitcoin is taking steps to protect itself against quantum attacks, which could potentially compromise its security. Researchers have been working on upgrades to make Bitcoin more resilient to such threats.

StarkWare researcher Avihu tested an experimental quantum-resistant transaction on the mainnet that protects it during a brief period when public keys are exposed in the mempool. The transaction used Levy's Quantum Safe Bitcoin (QSB) scheme, which combines hash-based one-time signatures with computational searches that bind an authorization to a specific transaction.

The QSB scheme is more of a last resort than a practical measure, as each transaction takes hours and costs $150-$200. However, it demonstrates the potential for quantum-resistant transactions on the Bitcoin network.
