LAS VEGAS, May 23, 2025 Quantum Safe Technologies Corp, the research collective building qBTC, the worlds first quantum-safe sidechain for Bitcoin, today announced it will publish the full source code of its proof-of work- side chain protocol during the Bitcoin 2025 Conference in Las Vegas. The open-source release marks a major milestone in bringing post-quantum security to Bitcoin users while preserving the assets decentralization ethos.

Alongside the code launch, qBTC is pleased to welcome noted Bitcoin engineer and security advocate Jameson Lopp as a strategic advisor. Lopp will guide the projects roadmap and help steward community discussions around quantum-resilient upgrades to Bitcoin infrastructure. In parallel, qBTC has formally endorsed a new Bitcoin Improvement Proposal (BIP) authored by Lopp as well as several quantum researchers that outlines a phased path for adding post-quantum signature options to Bitcoin mainnet and sunsetting legacy ECDSA outputs.

Quantum computing is no longer a distant threat; it is an engineering timeline, said Christian Papathanasiou, chief architect of qBTC. Open-sourcing our stack is the fastest way to invite peer review, harden the code, and accelerate adoption. Jamesons deep experience in Bitcoin security and operational readiness makes him the ideal advisor as we transition from research to production.

In June of 2010, in a post on Bitcointalk, Satoshi acknowledged that Bitcoins cryptography could one day be threatened by a massive breakthrough attack.

The qBTC sidechain integrates post quantum lattice based cryptography (ML-DSA) to futureproof and safeguard Bitcoin users against quantum attacks.

Lopps BIP, backed by qBTC engineering resources, proposes introducing quantum-safe cryptography on Bitcoin mainnet. Over a multi-year transition, wallets and exchanges could migrate funds to these outputs ahead of any cryptographically-relevant quantum breakthrough. The BIP also contemplates a failsafe bridge to qBTC so that users have an immediate refuge if quantum capability arrives sooner than expected.

I have argued for some time that the Bitcoin ecosystem must act proactively on quantum risk rather than react once keys are being compromised, said Jameson Lopp. qBTCs open-source layer 2 provides a living testbed for post-quantum cryptography today, and the accompanying BIP charts a clear, minimally disruptive upgrade path for tomorrow.

Key details of todays announcement:

  • The qBTC source code repository and developer documentation will go live during the keynote session at Bitcoin Conference Las Vegas. Contributors are encouraged to review, audit, and submit pull requests via the project GitHub.
    " Lopp joins qBTCs advisory board effective immediately, focusing on security audits, threat modeling, and community outreach.
    " qBTC will begin hosting weekly public calls to discuss the BIPs implementation details, inviting wallet developers, miners, and node operators to weigh in.

qBTC expects its testnet to enter public beta shortly after the conference, with mainnet release contingent on satisfactory third-party audits and broad ecosystem support. Interested developers can sign up for early access and technical updates at [ https://qb.tc ].

About qBTC
Founded in 2024, qBTC is an independent, open-source initiative dedicated to securing Bitcoin against the emerging threat of quantum computing. qBTC is building a coalition of researchers, cryptographers, and thought leaders to address the looming quantum threat.

The projects side chain architecture enables scalable, low-fee transactions anchored to Bitcoins proof-of-work while leveraging post-quantum cryptography to safeguard keys for decades to come. For source code, documentation, and community channels, visit [https://qb.tc].
