Time-Zone Optimized Environmental Consensus: A Theoretical Framework for Sustainable Blockchain Systems

Abstract

This paper suggests a theoretical framework towards a new consensus mechanism in blockchain systems that deals with critical sustainable issues in distributed ledger technologies. The aim is to formulate an energy efficient approach to blockchain consensus while preserving the elements of decentralization and security. We propose Time-Zone Optimized Environmental Consensus (TZOEC) which takes advantage of the geographical time-zone distribution of validators while giving priority to renewable energy sources based on dual-factor scoring. The former is what focuses on energy metrics whereas the latter focuses on geographic attainability synchronizing prime time zones to increase energy efficiency. With this TZOEC, the theory is that it addresses the gaps in the current mechanisms of consensus by providing a balanced framework of unchained access, sustainable security, and environmental mindful frameworks without straining finances. Mathematical modeling and theoretical analysis indicate that TZOEC might achieve 18.5% less energy waste than PoW, sitting at around 620 TPS, while the ratio of used renewable energies could reach over 45%, signifying a tremendous leap over other consensus mechanisms if put into action.
