Ethereum has achieved a major milestone with its transition to a Proof-of-Stake (PoS) system, achieving an impressive 99.95% reduction in energy consumption according to the Ethereum Foundation. This groundbreaking move signals a significant shift towards sustainability in blockchain technology and aligns with growing institutional interest in eco-friendly crypto options. The PoS consensus mechanism pioneered by Ethereum has become a global standard for scalable and energy-efficient blockchain development. 70% of the global blockchain network is now running on this system, including projects like Cardano. Ethereum’s success signifies the potential for sustainable blockchain solutions to gain traction in the financial sector.
