First Quantum Safe Bitcoin Transactions are completed on Bitcoin Homenet

On 27 August, the Starknet team developer, Avihu Levy, completed a BTC deal using the Quantum Safe Bitcoin, QSB methodology in the Bitcoin main network. It is known that Avihu Levy and others introduced the Quantico Safety Bitcoin (QSB) programme in April 2026, which allows Bitcoin to sign a Bitcoin transaction in a way that allows it to remain safe even in the face of attackors with large-scale quantum computers operating the Shor algorithm, and which does not require any changes to the TCO agreement。
