Developing distributed ledger (blockchain) tools to facilitate efficiency and trust in international nuclear materials accountancy stakeholder networks

Body Text

Competitive advantage 

  • World-first demonstration of blockchain technology for nuclear materials accounting
  • Unique integration of proficiency in global regulatory regimes (nuclear safeguards & nuclear security) and geopolitical understanding, with computer science and engineering
  • Combining scale and agility to execute significant and novel projects
  • Achieving the right balance of confidentially and participation in stakeholder networks characterised by a widely varying degree of trust


  • Nuclear materials accountancy is the core of the International Nuclear Safeguards regime—the accounting, audit systems and legal frameworks used by the International Atomic Energy Agency to verify that nuclear materials are used for exclusively peaceful purposes. Nuclear Safeguards are the obligations of signatories to the Treaty on the Non-proliferation of Nuclear Weapons.
