Ethereum Might Introduce New Staking Mechanism in 2019
It's worth noting that my knowledge cutoff is September 2021, and as of that time, Ethereum had already introduced a new staking mechanism in late 2020 as part of the Ethereum 2.0 upgrade.
The Ethereum 2.0 upgrade introduced a new consensus mechanism called Proof of Stake (PoS), which is a departure from the current Proof of Work (PoW) consensus mechanism. Under PoS, users who hold a certain amount of Ethereum can stake their coins and participate in the validation and processing of transactions on the network, in exchange for rewards.
This new staking mechanism is a significant improvement over the previous PoW system, as it is more energy-efficient and allows for greater scalability and security on the Ethereum network. It also allows more users to participate in the network's operations, as it doesn't require the use of expensive mining hardware.
As of my knowledge cutoff of September 2021, the Ethereum 2.0 upgrade was still being rolled out, and there were a significant number of Ethereum holders who had staked their coins in order to participate in the network's operations. The introduction of this new staking mechanism was a major development for the Ethereum ecosystem, and has the potential to significantly improve the network's capabilities going forward.
