BTQ Deploys First Working BIP 360 Implementation On Bitcoin Quantum Testnet

"BIP 360 represents the Bitcoin community's most significant step toward quantum resistance and we've turned it from a proposal into running code. The implementation also preserves key functionality tied to Bitcoin's scaling roadmap. According to BTQ, P2MR maintains compatibility with scripting features that underpin systems like Lightning and emerging frameworks such as BitVM and Ark, while eliminating the key-path spend mechanism introduced with Taproot that could expose public keys to quantum attacks."

"BIP 360 introduces a new transaction format known as Pay-to-Merkle-Root (P2MR), which restructures how transaction data is committed on-chain. The design removes the need to expose public keys during certain transaction paths, a feature that could become critical if quantum computers advance enough to break current cryptographic protections."

"Beyond the core transaction structure, the testnet includes full wallet tooling, allowing users to create, fund, sign, and broadcast P2MR transactions. BTQ said this end-to-end functionality makes the upgrade immediately testable, rather than remaining a purely academic proposal."

BTQ Technologies has deployed the first functional implementation of Bitcoin Improvement Proposal 360 (BIP 360) on the Bitcoin Quantum testnet v0.3.0, moving quantum-resistant infrastructure from theoretical proposal to practical testing. BIP 360 introduces Pay-to-Merkle-Root (P2MR), a new transaction format that restructures on-chain data commitment and eliminates public key exposure during certain transaction paths, protecting against potential quantum computing threats to current cryptography. The implementation maintains compatibility with Bitcoin's scaling roadmap, including Lightning Network, BitVM, and Ark frameworks, while removing the key-path spend mechanism from Taproot that could be vulnerable to quantum attacks. The testnet includes complete wallet tooling enabling users to create, fund, sign, and broadcast P2MR transactions, making the upgrade immediately testable rather than purely academic.
