StarkWare Quantum Bitcoin Transaction: First Quantum-Resistant BTC Transaction Hits Mainnet

StarkWare said researcher Avihu Levy tested an experimental quantum resistant Bitcoin transaction on mainnet. It is reported that the TX spent a 10,000-satoshi output in block 964,199 without altering Bitcoin’s consensus rules.

StarkWare described it as the first transaction of its kind. MARA Pool mined the block after receiving the transaction directly through its Slipstream service, since the nonstandard format meant ordinary nodes would not relay it through the public mempool.

StarkWare spokesperson Nathan Jeffay said the transaction cost around $150 to $200 in computation, and StarkWare said the process took hours. The demonstration shows a way to protect a single output under Bitcoin’s current rules, but at a material computational and operational cost.
