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. Ironically, 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. Initiatives in this direction have already commenced (e.g. the Crypto Climate Accord).

This project aspires to contribute to this endeavor. The project has a dual aim:

  • To investigate and develop novel efficient computational resource management algorithms and mechanisms to increase scalability and reduce the energy requirements to achieve sustainable blockchains
  • To demonstrate the robustness of the developed mechanism in the context of sustainability applications
