BTQ enables quantum-safe Bitcoin transactions on testnet implementing BIP 360

BTQ brings BIP‑360 from draft to code. The firm launched Bitcoin Quantum testnet v0.3.0 with the first working P2MR implementation for quantum‑resistant transactions (PRNewswire).

The testnet lets developers, miners, and researchers create, sign, and spend P2MR transactions on a live network. It shows mempool acceptance, broadcast, and confirmation end to end (PRNewswire).

BIP‑360, or Pay‑to‑Merkle‑Root, commits to a script tree’s Merkle root. It keeps Taproot’s flexibility and removes the key‑path spend that exposes public keys. That design targets the long‑term risk of Shor’s‑style quantum attacks on on‑chain public keys (PRNewswire, on‑chain public keys).

What’s live now:
- Full P2MR consensus rules with SegWit v2 outputs and bc1z bech32m addresses (PRNewswire)
- Merkle root commitment verification and control block validation (block validation)
- All five Dilithium post‑quantum signature opcodes within P2MR tapscript (PRNewswire)
- CLI and full RPC wallet support for complete P2MR flows (PRNewswire)
- Network‑activated feature across Bitcoin Quantum testing environments (PRNewswire)

Context for investors: Taproot, activated in 2021, put more public keys on‑chain, increasing the future quantum attack surface for Bitcoin (BTC). P2MR removes the key‑path exposure while preserving Taproot scripts (on‑chain public keys).

BTQ’s CEO called it a shift from theory to practice. “BIP 360 represents the Bitcoin community’s most significant step toward quantum resistance, and we’ve turned it from a proposal into running code” (PRNewswire).
