As global attention to environmental protection and sustainable development continues to increase, more and more blockchain projects in 2024 are beginning to focus on energy consumption and carbon emissions issues. In 2025, green blockchain technology will become an important development direction in the cryptocurrency space. Major cryptocurrency projects may adopt more environmentally friendly consensus mechanisms (such as PoS, PoA, etc.) and invest in blockchain applications for renewable energy to respond to the pressure of global environmental protection policies and meet society's demand for a green digital economy.
