Blockchain-Based Ship Energy Consumption Data Access and Control

With the continuous development of the maritime industry and the increase in global environmental awareness, reducing carbon emissions from ships has become a global consensus. Under the current Internet environment, maritime ship energy consumption data has data access control and data traceability problems, and how to collect ship energy consumption carbon tax is also a problem. Ship energy consumption data is an important basis for assessing ship performance, optimising ship operation and reducing carbon emissions, so how to collect, store and securely access these ship energy consumption data has become a key research direction. Therefore, this paper proposes a blockchain-based scheme for accessing and controlling ship energy consumption data.
