![]() ![]() A participating device may still have to meet some requirements (e.g. ![]() PoS may only incentivize acquiring a higher stake to increase the odds of creating a new block, but the computational power of the underlying device is not relevant to this process. Regardless of whether a network runs PoW or PoS, creating the next block for the blockchain will provide the creator with a reward, but in PoW the chance of obtaining this reward could only be increased by employing more energy-hungry devices. put “at stake”), in which the software then randomly selects a “staker” to create the next block for the blockchain. Coins are locked up as collateral in the staking process (i.e. Instead, wealth plays a key role in the block creation process that makes use of PoS. As a result of this change, there’s no longer a network of energy-intensive mining devices competing with each other in order to create the next block for the underlying blockchain anymore. However, on the 15th of September 2022, Ethereum replaced its PoW mechanism with an alternative known as proof-of-stake (PoS). The Ethereum Energy Consumption Index was designed with the same purpose, methods and assumptions as the Bitcoin Energy Consumption Index.
