StarkWare runs experimental quantum-resistant Bitcoin spending on mainnet

The test transaction reportedly cost up to $200 and required direct submission to miners.

StarkWare said it has executed an experimental, quantum-resistant Bitcoin transaction on the mainnet without requiring a fork, showing a path to Bitcoin spending that aims to be resilient to future quantum computing threats.

In details shared by the company via Cointelegraph, StarkWare said the approach worked without changing the protocol during the test, but it involved limitations including a cost of up to $200 and the need for direct submission to miners.

The Block also noted that StarkWare emphasized the wider need for a protocol-level upgrade, saying Bitcoin still is not fully safe from quantum computing threats absent broader changes.

Taken together, the test highlights both progress on quantum-resistant spending mechanics and the remaining work to make protection comprehensive across the network.
