BTQ Technologies said that Bitcoin Quantum testnet v0.3.0 now includes the first working implementation of BIP 360, a quantum-resistant Bitcoin output model built around Pay-to-Merkle-Root. The company announced the rollout in a news release and amplified it through its X account.

The release frames BIP 360 as a direct response to Taproot’s long-term quantum vulnerability, saying the new design preserves scripting functions used by Lightning, BitVM and Ark while removing the key-path spend that could expose public keys to future attacks via Shor’s algorithm. BTQ added that end-to-end CLI wallet tooling is already live on testnet, allowing users to create, fund, sign and spend P2MR transactions now.
The bigger challenge is adoption. BTQ acknowledged that BIP 360 is still only a draft within Bitcoin’s broader proposal process and that implementation across the ecosystem remains limited. The company also noted Bitcoin’s conservative upgrade culture, pointing out that SegWit took about 8.5 years to reach adoption and Taproot about 7.5 years. What comes next is whether developers, miners and researchers use the testnet enough to turn this from a working prototype into a serious path for future Bitcoin security upgrades.
