POS or Proof of Stake is a type of consensus algorithm that is used to achieve distributed consensus. It is an alternative to the more common Proof of Work (POW) consensus algorithm. In POW, miners compete against each other to validate transactions and add blocks to the blockchain.
The one who solves the puzzle first gets to add the block and receives a reward. This process uses a lot of energy and is quite slow.
In POS, on the other hand, validators stake their coins to validate transactions and add blocks to the blockchain. The more coins they stake, the higher their chances of being selected to validate a block.
If they validate a block successfully, they receive a reward. This process is much faster and uses less energy than POW.
NOTE: WARNING: Mining Ethereum is a complex process that requires specialized hardware, software, and technical knowledge. Attempting to mine Ethereum without the proper knowledge and resources can lead to significant losses of time, money, and effort. Additionally, miners must be aware of the risks associated with Proof-of-Stake (POS) mining and understand how POS works before attempting to mine Ethereum using POS.
POS is considered more secure than POW because it is not possible for an attacker to 51% attack the network. In a 51% attack, an attacker would need to control more than half of the total mining power in order to be able to add blocks faster than the rest of the network and reverse transactions.
This is not possible in POS because an attacker would need to own more than half of all the coins in order to have a majority stake in the network.
What does this mean for Ethereum miners? Ethereum plans to switch from POW to POS in the near future. This means that miners will need to stake their ETH in order to continue validating transactions and earning rewards.
The switch from POW to POS will be gradual and will happen over multiple stages. Ethereum miners who want to continue earning rewards will need to stake their ETH and run a node when POS goes live on mainnet.

Miner fees are the cost a miner incurs for verifying and including a transaction in their block. The fee is collected by the miner who successfully mines the block that includes the transaction. Ethereum’s transaction fee system is designed to pay miners based on their computational power, rather than their staking position like in Proof of Stake.
An Ethereum ASIC miner is a type of cryptocurrency mining equipment that is used to mine for the Ethereum cryptocurrency. ASIC miners are designed specifically for mining cryptocurrencies and are much more efficient than traditional CPU or GPU miners. Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference.
Miner fees are the cost that a cryptocurrency miner charges for verifying and including a transaction in their block. In the case of Ethereum, miners are rewarded with ETH for their work. The amount of ETH they earn per block is reduced by a small amount each year as part of the Ethereum protocol’s “block reward reduction” schedule.
Ethereum miner fees are high because the network is congested. There are more transactions than there is space to include them in each block, so miners have to prioritize which ones to include. They do this by looking at how much fee each transaction has attached to it.
As of July 2019, there are many Ethereum mining software options available. The most popular are Ethminer, Claymore and Phoenix. All three have their own advantages and disadvantages.
