Consensus Mechanism for Environmental Blockchain: Proof-of-eco-awareness (PoEa)

Abstract

There are numerous consensus mechanisms existing in various blockchain networks, regardless of the process that requires independence, agility, and credibility in digital records. Therefore, the objective of this study was to create a consensus mechanism process (pseudocode) exclusive to environmental occurrence records, allowing the validation of records and blocks with specific and careful criteria for the environment. The justification for its creation, despite the efficient and practical dynamics of other existing consensuses, was to enumerate treatments that cater to nature and biodiversity. Environmental occurrence records require a sensitive and qualified view of the data handled because they involve nature, society, and life in general. As a methodology, a descriptive and bibliographic research was implemented, understanding the functioning of the most common consensuses, each with its particularities. Additionally, symbols were applied to represent these occurrences, enabling digital interpretations of contents that are generally and purely analog, such as a simple rain event, now understood as a code that represents it, in terms of its impact on the environment. Furthermore, official codes that already represent natural or technological disaster occurrences were applied. These symbols will allow the classification of these occurrences for the technical selection of data validators.
