About BlockSphere
We're a specialist consulting firm helping organisations navigate blockchain technology and prepare for the post-quantum era.
Our Mission
The technology landscape is changing rapidly. Blockchain is reshaping industries, while quantum computing threatens the cryptographic foundations of our digital world. Many organisations are struggling to separate genuine opportunity from hype, and real threats from speculation.
We founded BlockSphere to provide clear, evidence-based guidance. We help organisations make informed decisions about emerging technologies—embracing real opportunities while preparing for genuine risks.
"Cut through the noise."

Every organisation is different. We adapt our approach to your specific context, constraints, and objectives.
Our Expertise
Deep technical knowledge across two critical areas of emerging technology.
Blockchain & Web3
Comprehensive expertise across the blockchain ecosystem, from protocol-level understanding to application development.
Post-Quantum Cryptography
Specialist knowledge in quantum-resistant cryptographic standards and migration strategies.
Our Team
Led by experienced researchers and practitioners in blockchain and cryptography.
Dr. Joseph Kearney
Founder & Lead Consultant
Post-quantum cryptography researcher with a PhD from the University of Kent and over 8 years of experience at the intersection of blockchain, cryptography, and quantum computing.
Joseph's published research on quantum threats to Bitcoin and Ethereum has shaped industry understanding of post-quantum migration challenges.
Beyond Consulting
We also run FUD or Fact—a platform dedicated to separating quantum computing hype from reality. It's part of our commitment to bringing clarity to a space often dominated by sensationalism.
