Proof-of-Green (PoG) is a consensus mechanism designed to promote sustainability in blockchain networks. It aims to minimize energy consumption and reduce environmental impact compared to traditional methods like Proof-of-Work.In a PoG system, nodes are incentivized to validate transactions based on their energy efficiency and the use of renewable energy sources. This can help decrease the carbon footprint associated with maintaining the network.By incorporating sustainability into the consensus process, PoG encourages participants to adopt green technologies and practices. This approach not only supports eco-friendly initiatives but also appeals to environmentally conscious users and investors. Promoting a more sustainable alternative helps mitigate the criticisms surrounding the environmental impact of cryptocurrencies, making PoG an attractive option for future blockchain development.
