Energy-efficient consensus mechanisms

Definition

Energy-efficient consensus mechanisms are methods used in blockchain networks to validate transactions and secure the network with minimal energy consumption. These mechanisms aim to reduce the environmental impact of traditional consensus methods, such as Proof of Work, by utilizing alternative approaches like Proof of Stake or Delegated Proof of Stake. This shift is crucial in addressing concerns about the carbon footprint associated with blockchain technology, especially as it continues to grow in popularity and usage.

Related terms

Proof of Work:

A consensus algorithm that requires participants to solve complex mathematical problems to validate transactions and create new blocks, consuming significant amounts of energy.

Proof of Stake:

A consensus mechanism where validators are chosen to create new blocks based on the number of coins they hold and are willing to 'stake' as collateral, leading to lower energy consumption.

Delegated Proof of Stake: An evolution of Proof of Stake where stakeholders elect delegates to validate transactions and maintain the blockchain, further improving efficiency and reducing energy use.
