Quantum Secured Blockchain (QSB) Whitepaper Published

Building off the back of our earlier milestones involving the implementation of the CRYSTALS-Dilithium post-quantum algorithm in the Rust language and the use of QKD technology in our Substrate based blockchain, we are happy to announce the completion of our Quantum Secured Blockchain (QSB) Whitepaper.  This represents the achievement of another significant milestone within our roadmap. The whitepaper was authored by our own scientists and developers: Dr. Mirek Sopek, Dr. Marta Misiaszek-Schreyner, Dr. Miriam Kosik, Dr. Piotr Kulicki and Lukasz Kujawski.  It goes into the history of the development of our proprietary QSB against the backdrop of the emerging quantum era and the risk quantum computing poses to current encryption standards underpinning most of today’s software and blockchains.  It also goes into the technical details behind the three fundamental technology pillars of our QSB which are (1) Quantum Key Distribution to protect blockchain network communication (2) Quantum Random Number Generator (QRNG) to provide the highest possible entropy for various randomness requirements on the blockchain and (3) Post-Quantum Cryptography (PQC) for signatures, keys and addresses.  All these technologies have been incorporated using the Substrate based blockchain platform to create our QSB. Our next steps will include perfecting the QSB demonstrator and developing a testnet by the end of Q1 2024 with the goal of launching our mainnet by Q3 2024.  To download our whitepaper and learn more about our QSB, please visit
