BTQ Technologies Deploys BIP 360 Testnet to Shield Bitcoin From Quantum Threats
- BTQ Technologies launched BIP 360 on its testnet to trial Bitcoin quantum defenses
- The rollout adds P2MR, SegWit v2, bc1z addresses, and Dilithium signature testing
- BIP 360 remains a draft, making this a research milestone rather than a Bitcoin adoption
BTQ Technologies has moved a long-running research question in Bitcoin security out of theory and into a live testing environment. On Thursday, the company said it deployed the first working implementation of BIP 360 on its Bitcoin Quantum testnet v0.3.0.
The release gives developers, miners, and researchers a place to test how quantum-resistant transaction behavior could work before any similar change is considered for the Bitcoin network. The release matters as it turns a draft idea into functioning code.
Rather than arguing abstractly about how Bitcoin should prepare for future quantum risks, the testnet lets participants examine a practical model with live transaction handling, mining activity, and wallet support.
BTQ Technologies framed the rollout as an engineering milestone while making clear that the work exists on a separate test network and does not represent adoption by Bitcoin Core or the Bitcoin mainnet.
Draft Proposal Moves Into Working Code
At the center of the release is BIP 360, a draft soft-fork proposal listed in Bitcoin’s public BIPs repository. The proposal introduces a new output type called Pay-to-Merkle-Root, or P2MR, which is designed to preserve the script-tree functionality associated with Taproot while removing the key-path spend that its authors describe as vulnerable in a future quantum-computing scenario.
In simple terms, the proposal focuses on one narrow problem: reducing the exposure of public-key data that is already visible on-chain. Its authors describe that risk as a “long exposure” issue, meaning coins tied to already revealed key material could become more vulnerable if cryptographically relevant quantum computers ever emerge. The draft, however, does not present itself as a complete answer to every quantum security concern. Instead, it positions P2MR as a first defensive step.
What the Testnet Actually Adds
According to BTQ Technologies, the Bitcoin Quantum v0.3.0 release includes full P2MR consensus support, SegWit version 2 outputs, bc1z address encoding, and end-to-end wallet RPC tooling. The company said users can create addresses, sign transactions, broadcast them, and track confirmation through the test environment.
The implementation also adds Dilithium-based post-quantum signature opcodes inside the P2MR tapscript context. That makes the network more than a draft demonstration. It functions as a sandbox where researchers can test how post-quantum transaction flows might behave on a system built to resemble Bitcoin while remaining operationally separate from it.
BTQ Technologies also reported that the test network now has more than 50 miners and more than 100,000 mined blocks, alongside an active contributor base. Public materials for outside participants include v0.3.0 binaries, documentation, a block explorer, and mining resources. Those figures are company-provided metrics and describe activity on Bitcoin Quantum, not on Bitcoin itself.
Why Quantum Risk Is Now a Policy Issue
The timing of the rollout reflects a broader shift in cryptography policy. In August 2024, NIST finalized FIPS 204, standardizing ML-DSA as a post-quantum digital signature method. Separate guidance from the agency has also outlined a transition path away from public-key systems considered vulnerable in a future quantum era, with some elliptic-curve and RSA uses set to become disallowed after 2035 in federal standards.
That policy backdrop gives added relevance to BIP 360. The proposal arrives as post-quantum security is moving from academic debate into formal planning across institutions and engineering teams.

Research Milestone, Not Network Consensus
Even so, the release does not signal imminent change for Bitcoin. The bitcoin/bips repository states that publication does not imply community consensus, and BIP 360 remains a draft specification. That distinction is central to understanding the announcement.
What BTQ Technologies has delivered is a research venue with working code, measurable network activity, and a clear technical target. It does not settle whether Bitcoin will adopt a similar design, but it does give the wider ecosystem something more concrete than theory: a live test case for how quantum-resistance proposals can be examined before they ever reach the governance stage.
