Sustainable Blockchains

The potential of blockchain technology to support sustainable development is well acknowledged while tokenisation is viewed as the key technology to promote and power ESG, impact investment and sustainable finance. However, blockchain technology faces a sustainability challenge itself due mainly to the industry's expanding carbon footprint. There is therefore a pressing and urgent need to enhance and develop blockchain technology further and achieve blockchain sustainability. This project aspires to contribute to this endeavor.

  • It expands the well known trilemma tradeoff to render it “energy aware” with sustainability as a fourth dimension
  • It develops a novel Digital Twin system for the dynamic management of Blockchains
  • It investigates and develops novel efficient computational resource management algorithms and mechanisms to manage the trilemma tradeoff while reducing the energy requirements
