The topic of blockchain in the context of achieving sustainable development goals is associated exclusively with its high carbon footprint—energy consumption and postulates to reduce it in blockchain-based systems, basing their functioning on renewable energy sources or, in the extreme case, eliminating them. However, on the other scale of assessing this technology, we can put its unique properties, on which new types of assets are based, new services, providing transparency, security, indisputability, integrity, increasing certainty in business relations, and ensuring equality in these relations. All these blockchain products can potentially help in achieving at least several of them. The chapter is to present an analysis of the potential for achieving all goals and an analysis of examples of projects that realise this potential in reality.
