Cardano’s Ouroboros protocol uses Proof-of-Stake (PoS) consensus, consuming significantly less energy compared to Proof-of-Work (PoW) systems like Bitcoin.
Algorand takes sustainability seriously with its low-energy Pure Proof-of-Stake (PPoS) model and a commitment to offsetting its carbon footprint.
Hedera’s network achieves high throughput using asynchronous Byzantine Fault Tolerance while maintaining an eco-friendly energy profile.
Solana’s unique Proof-of-History (PoH) and PoS blend minimizes energy usage while supporting lightning-fast transactions.
Chia utilizes a Proof-of-Space-and-Time mechanism, replacing energy-intensive mining with disk space farming to drastically cut energy costs.
