Existing national registries of, for example, decentralised power plants (e.g. solar), or electric vehicle fleets, may well be mapped on a blockchain layer with the required information for global monitoring and reporting services. Primarily given the fast changing maturity of protocols and interfaces, the platform must maintain a high degree of flexibility by comprising clearly defined modules. In order to cater to the requirements best while balancing efforts and costs of operating the platform, the following initial design is proposed. Table 6 summarises the suggested technical aspects. Validators are the entities that initially create the network, for example the UNFCCC countries.
