StarkWare Tests Quantum-Resistant Bitcoin Transaction on Mainnet
StarkWare researcher Avihu Levy has successfully tested an experimental quantum-resistant Bitcoin transaction on the mainnet, marking the first of its kind. The transaction was confirmed in Bitcoin block 964,199 and spent a 10,000-satoshi output protected by Levy's Quantum Safe Bitcoin (QSB) scheme.
The test demonstrates that Bitcoin's existing consensus rules can accommodate one form of quantum-resistant spending without a protocol change. Levy introduced QSB in April, estimating that generating a transaction would require between $75 and $150 in GPU computation.
StarkWare spokesperson Nathan Jeffay told Cointelegraph that the completed transaction cost 'low hundreds of dollars,' estimating the expense at around $150 to $200. The process took hours of computation.
