BTQ ships working BIP 360 P2MR on Bitcoin Quantum Testnet v0.3.0

BTQ Technologies says it has deployed a working Bitcoin Improvement Proposal 360 (BIP 360) implementation on its Bitcoin Quantum Testnet v0.3.0. The focus is Pay-to-Merkle-Root (P2MR) outputs, designed to reduce long-exposure quantum risk by removing Taproot key-path spending and forcing UTXOs through hash-based script paths. In its v0.3.0 release, BTQ claims end-to-end validation of the BIP 360 P2MR lifecycle: address creation and funding, signing, mempool acceptance, broadcast, and confirmation. It also says the test is compatible with Lightning, BitVM, Ark, multisig, and timelocks, positioning the change as additive rather than disruptive. The test uses one-minute blocks for faster iteration, restores the SegWit discount, and adds Dilithium/ML-DSA signature hardening. BTQ frames BIP 360 as a mitigation for “harvest-now, decrypt-later” exposure from on-chain public keys, while noting it does not yet address “short-exposure” attacks where signatures could be broken before confirmation. For traders, this is a credible research milestone for post-quantum Bitcoin transaction formats, but it is not an immediate mainnet upgrade. Near-term market repricing is therefore likely limited, though sentiment around Bitcoin security and future protocol upgrades may improve.
