BTQ Technologies Deploys First Working Quantum-Resistant Bitcoin Implementation as Core Development Stalls
-
Quantum computers cannot break Bitcoin yet. The emphasis is on yet. A Canadian technology company just became the first to deploy a working implementation of the solution Bitcoin developers have been debating for months, and it did so while the broader Bitcoin ecosystem has made virtually no progress toward the same goal.
BTQ Technologies activated Bitcoin Improvement Proposal 360 on its Bitcoin Quantum testnet this week, moving what had been a theoretical proposal into functioning, testable infrastructure available to developers, miners, and researchers right now.
Why Bitcoin Has a Quantum Problem
The issue sits inside Taproot, the upgrade Bitcoin activated in 2021 that underpins Lightning Network, BitVM, and other next-generation applications. Taproot’s design includes a mechanism that can expose public keys on-chain. When quantum computers become powerful enough to run Shor’s algorithm at scale, those exposed public keys become vulnerable to attack.
BIP 360 addresses this by introducing a new output type called Pay-to-Merkle-Root, which preserves all of Taproot’s scripting capabilities while removing the specific mechanism that creates the quantum vulnerability. It is a targeted fix rather than a rebuild.
What BTQ Actually Built
The company has implemented BIP 360 on a live testnet with more than 50 miners, over 100,000 blocks mined, and full end-to-end wallet tooling that allows users to create, fund, sign, and spend quantum-resistant transactions today.
It also includes five post-quantum signature algorithms operating inside the script tree, complete address creation, transaction construction, and confirmation capabilities.
The Timeline Problem
Bitcoin’s governance culture is deliberately conservative. SegWit took 8.5 years from concept to adoption. Taproot took 7.5 years. BIP 360 has entered the official proposal repository but Bitcoin Core has made no implementation progress.
Meanwhile US federal agencies face an April 2026 deadline to submit post-quantum transition plans. The European Union has set a 2030 quantum-resistance target for critical infrastructure. Canada’s new procurement requirements take effect next month.
BTQ’s CEO Olivier Roussy Newton framed the urgency simply: “The industry can’t afford to treat quantum resistance as a theoretical exercise.”
The quantum threat to Bitcoin is not immediate. But the time required to implement a fix, measured historically in years, suggests that waiting until the threat becomes urgent may already be waiting too long.
