Ethereum's Game-Changing Switch to Proof of Stake Cuts Energy Use by 99.95%

The Ethereum network has undergone a significant transformation in recent years, shifting from proof of work to proof of stake. This change has reduced energy consumption by 99.95%, making it one of the most environmentally friendly blockchain networks.

Proof of stake is a consensus mechanism that relies on validators locking up cryptocurrency as collateral. These validators propose and verify blocks, and if they cheat, their deposit is destroyed. This approach eliminates the need for expensive mining rigs and electricity consumption.

The concept of proof of stake has been around since 2012, but it wasn't until Ethereum's September 2022 Merge that it became widely adopted. Today, proof of stake underpins most major blockchains by market capitalization.
