Transition to POS is a key change for Ethereum blockchain: here’s why

By MakeItReal | MakeItReal | 17 Nov 2020


Ethereum blockchain is taking the final steps to move from Proof Of Work consensus mechanism to Proof Of Stake system.

Proof Of Stake is a consensus mechanism that allows the securing of the network through distributed consensus.

Ethereum POS needs Validators, hodlers who stake at least 32 ETH (if you have less than 32 ETH, you will be able to add a smaller stake to staking pools), to create, checking and confirming blocks. 

Transition to Proof Of Stake involves many improvements over the previous Proof Of Work consensus mechanism:

  • Better energy efficiency: hardware consuming huge amounts of energy like GPU or ASIC are no longer needed with the transition to Proof Of Stake.
  • Lower barriers to entry: POS validators won’t need elite and expensive hardware like GPU or ASIC to stand a chance of creating new blocks. With POS, if you have less than 32 ETH you can equally stake ethereum through staking pools available on sites like Binance, Rocketpool and many others.
  • Increased decentralization: POW mechanism was dependent on a small number of large mining pools due to the rush to produce faster and more sophisticated hardware mining. POS will lead to more nodes in the network.
  • Safer network: Ethereum Proof Of Stake will integrate the Casper security protocol, a security mechanism that will delete validator’s deposit if the staker acts in a fraudulent way.
