When a cryptocurrency holder initiates a transaction sends payment , there are typically hundreds of thousands of miners competing to validate the transaction. The higher the hashing power, the higher the chances of guessing or solving the mathematical puzzle correctly. The validation process is complete when a miner successfully adds the transaction and secures it to the blockchain network. The miner earns a fraction of the mined token as a reward. Hashing rate is the power a mining computer hardware requires to solve complex mathematical algorithms.

YCharts revealed that there were appropriately 1. To determine which of the computers will process the transaction, without being biased, all computers are open to compete and solve these huge volume, only a few will succeed.

My dummy hashing algorithm is going to create 4-character alpha-numeric character identifications for texts. Using SHA the hash algorithm used in Ethereum. Ethereum typically gives out hashing puzzles that involve giving computers a text; the computers are expected to come up with a modification of that text that is —.

To win this type of puzzle, a computer will have to modify the given value continuously, until the hash value of the new modification meets the desired criteria. Ethereum, like Bitcoin, currently uses a proof-of-work PoW consensus protocol. Proof-of-work is done by miners , who compete to create new blocks full of processed transactions. The winner shares the new block with the rest of the network and earns some freshly minted ETH.

The race is won by whosever computer can solve a math puzzle fastest — this produces the cryptographic link between the current block and the block that went before. Solving this puzzle is the work in "proof-of-work". More on proof-of-work. Ethereum has plans to upgrade to a proof-of-stake PoS consensus protocol. Proof-of-stake is done by validators who have staked ETH to participate in the system. A validator is chosen at random to create new blocks, share them with the network and earn rewards.

Instead of needing to do intense computational work, you simply need to have staked your ETH in the network. This is what incentivises healthy network behaviour. And that your stake is slashed for malicious behaviour. More on proof-of-stake. Watch more on the different types of consensus mechanisms used on Ethereum:. Now technically, proof-of-work and proof-of-stake are not consensus protocols by themselves, but they are often referred to as such for simplicity.

They are actually Sybil resistance mechanisms and block author selectors; they are a way to decide who is the author of the latest block. Sybil resistance measures how a protocol fares against a Sybil attack. Sybil attacks are when one user or group pretends to be many users. Resistance to this type of attack is essential for a decentralized blockchain and enables miners and validators to be rewarded equally based on resources put in.

Proof-of-work and proof-of-stake protect against this by making users expend a lot of energy or put up a lot of collateral. These protections are an economic deterrent to Sybil attacks. A chain selection rule is used to decide which chain is the "correct" chain.

Ethereum and Bitcoin currently use the "longest chain" rule, which means that whichever blockchain is the longest will be the one the rest of the nodes accept as valid and work with. The combination of proof-of-work and longest chain rule is known as "Nakamoto Consensus. Eth2 the beacon chain uses a consensus mechanism called Casper the Friendly Finality Gadget , which is proof-of-stake based.
