BTQ Deploys First Bitcoin Quantum Testnet With BIP-360

BTQ launches Bitcoin Quantum testnet with BIP 360, introducing Pay to Merkle Root and enabling quantum resistant transaction testing.

BTQ Technologies has launched a new step in Bitcoin-focused research with a working quantum test environment.

The company confirmed that it deployed Bitcoin Improvement Proposal 360 on its Bitcoin Quantum testnet, offering a live setting for testing new transaction methods.

Testnet Launch Enables Live Quantum Resistant Transaction Trials

BTQ Technologies announced the release of Bitcoin Quantum testnet version 0.3.0. This network includes the first functional implementation of BIP 360.

The upgrade allows developers to test new transaction structures in a controlled environment.

The testnet is separate from the main Bitcoin network. It is designed to explore how Bitcoin could operate under future quantum conditions. This setup allows safe testing without affecting existing systems.

CEO Olivier Roussy Newton said, “BIP 360 represents the Bitcoin community’s most important step toward quantum resistance.” He added that the proposal is now active code rather than theory.

The release also includes full wallet support. Users can create and send transactions using the new format. This makes testing accessible for developers and researchers.

New Pay to Merkle Root Structure Introduced

BIP 360 introduces a new output type called Pay to Merkle Root. This format changes how transaction data is stored and verified. It also limits when public keys are exposed on-chain.

The design aims to reduce risks tied to quantum computing. Current systems rely on elliptic curve cryptography. Future quantum systems could weaken this protection.

By restructuring transaction paths, P2MR avoids exposing keys in certain cases.

This approach may help protect funds if quantum threats increase. The model also keeps compatibility with existing scripting tools.

BTQ stated that this format supports systems like Lightning and BitVM. It also aligns with scaling efforts already present in the Bitcoin ecosystem.

Testing Environment Expands Developer Access

The Bitcoin Quantum testnet includes full transaction workflows. Users can fund wallets and sign transactions within the system. This allows direct testing of new features.

Developers can observe how P2MR behaves under different conditions. The environment also helps test performance and security aspects.

This supports ongoing research into quantum-resistant systems.

BTQ said the goal is to provide a usable testing platform. The company aims to support collaboration across the developer community.

Researchers can build and test tools within this framework. The testnet also removes the key path spend model used in Taproot.

This change is intended to reduce exposure risks linked to public keys. The system continues to support flexible scripting options for developers.
