VANCOUVER, BRITISH COLUMBIA – October 23, 2025 – Today marks the official launch of the QCoin project, an ambitious initiative to build a next-generation, quantum-resistant blockchain designed for long-term security and decentralization. The project, detailed on its official website proofofquantum.org, aims to address the fundamental cryptographic vulnerabilities that future quantum computers pose to virtually all existing digital currencies, including Bitcoin and Ethereum.
To power its development and foster a community of early supporters, the project has launched a preliminary token, also named QCoin, on the Polygon network.
The security of modern digital infrastructure relies on cryptographic problems that are believed to be intractable for classical computers. However, the advent of fault-tolerant quantum computers threatens to break these standards, with algorithms like Shor’s capable of cracking the ECDSA signatures that protect wallets. The QCoin protocol is being engineered to be secure against these future threats by design.
“The quantum threat isn’t a matter of ‘if,’ but ‘when,'” says a Lead Researcher for the QCoin project. “Waiting for the threat to become imminent is not an option. We believe that the next great leap in blockchain technology is to build a protocol that is secure for the long-term future. QCoin is not just an iteration; it’s a necessary evolution to create a truly permanent and secure digital currency.”
Key innovations of the proposed QCoin mainnet include:
- Post-Quantum Signatures from Genesis: QCoin will be built with CRYSTALS-Dilithium, a NIST-selected post-quantum cryptographic standard, to protect user funds from quantum attacks from day one.
- A Novel, Grind-Resistant Proof of Work: The consensus mechanism is a new, memory-hard algorithm designed to be progress-free, promoting fairness and resisting the centralization caused by specialized hardware (ASICs).
- A Sustainable Economic Model: The protocol will inherit Bitcoin’s proven economic model, including a hard cap of 21 million coins and a predictable halving schedule.
The newly launched QCoin token on the Polygon network serves as the primary vehicle for funding this extensive research and development. It allows the community to support the project’s long-term vision and participate in its growth from the earliest stages.
“We are building this in the open and want the community to be part of the journey,” the researcher added. “The Polygon token is our way of aligning our success with our supporters. Every contribution helps fund the core development, security audits, and infrastructure needed to bring the QCoin mainnet to life.”
The core of the project’s community is the QCoin Research Group, a public Telegram channel where technical details, progress, and future plans are discussed.
About QCoin
QCoin is a research and development project dedicated to building a next-generation, post-quantum blockchain. It is designed to be a secure, decentralized, and sustainable peer-to-peer electronic cash system. The protocol’s core features include post-quantum cryptography from genesis and a novel, memory-hard Proof of Work consensus designed for fairness and ASIC resistance. The project is funded by a community-driven token on the Polygon network.
