QuStream is the strongest post-quantum encryption solution on Earth
Harvest now, decrypt later
Threat actors are already collecting encrypted databases and other sensitive information, intending to break the encryption once quantum computing becomes accessible. This practice, known as “harvest now, decrypt later”, poses a significant risk.

While some data may lose relevance by the time quantum computers can crack current encryption, a considerable portion - especially financial records, private keys, and personal identifiers will retain value and can be exploited for fraud and identity theft.

ABOUT
The World's Most Secure Quantum-Resistant Layer 1 Blockchain
Quantum security is the future, and our Layer 1 blockchain is built to thrive in it. As quantum computers threaten traditional cryptographic methods, blockchain and cryptocurrency must evolve to ensure secure transactions, data integrity, and user privacy. Our blockchain is designed with the strongest quantum-resistant encryption in the world at its core, leveraging a 504-bit quantum hardness. This ensures unparalleled protection against emerging quantum threats, making our network the most secure foundation for decentralized applications and digital assets.

Is BTC Ready for the Quantum Era?
As quantum computing advances, Bitcoin’s current cryptography could become vulnerable. Learn how quantum-safe encryption can protect BTC wallets, transactions and long-term value, and why preparing now is critical for Bitcoin’s future.
The End of Private Keys: What Comes Next?
Private keys have long been the gatekeepers of crypto — but they’re fragile, exposed, and deeply flawed. This article explores why QuStream is moving beyond private keys, embracing passphrase-based access and quantum-safe authentication to redefine how users secure their Web3 identities.
Rethinking Identity in Web3: Beyond Wallets and Logins
Web3 still relies on Web2 patterns of identity — wallets, logins, and fragmented access. This article explores how QuStream is redesigning identity from the ground up using encrypted passphrases, seamless delegation, and infrastructure built for true user sovereignty.

Adrian Neal
Adrian Neal, a two-time winner of the NATO Defence Innovation Challenge, is an internationally recognised Cybersecurity & Cryptographics expert, and currently holds the position of Senior Director and Global Lead for Post-Quantum Cryptography at Capgemini.

While primarily advising governments, defence organisations and global multi-nationals on post-quantum readiness, he is also a cybersecurity advisor regarding Central Bank Digital Currencies (CBDC), particularly in respect to the social and economic risks from future post-quantum cryptographic instability.

He is a graduate of Oxford University, from which he received a Masters’ Degree in Software Engineering and began his career at IBM in the mid 80’s, followed by a decade in the City of London, departing in ’98 for Zurich to join UBS Warburg as their first Cryptographics expert while becoming a member of the International Association for Cryptologic Research (IACR).

In almost 40 years, he has held positions in key financial and industrial sectors such as Banking, Insurance, Financial Markets, Energy, Pharma, IT, Aviation and Telecoms, across 8 countries and over 3 continents.

In 2012, he founded the Oxford University spinout Oxford BioChronometrics, developing the most advanced software for detecting fraud in online advertising, winning various blind-tests against ad-industry incumbents, with the research being cited by the Guardian, the Financial Times, the Wall Street Journal and both (US) Houses of Congress, while becoming a winner of the 2017 NATO NCIA Defence Innovation Challenge for Advances in Cybersecurity, and subsequently published in European Cybersecurity Journal.

In 2018, he founded Oxford Scientifica as a research organisation, focused on advanced military communications in low-bandwidth and spectrum-contested environments, becoming a winner of the 2019 NATO NCIA Defence Innovation Challenge for Signal Resilience in the High North.
