The idea was first introduced in , as an effective way to combat email spams. However, until the idea remained largely ineffective. Advertisement Satoshi Nakamoto, a pseudonymous Bitcoin creator , realised that this mechanism could be used as a way to secure the Bitcoin Blockchain.
The proof of work algorithm works by having all nodes devices to solve a cryptographic puzzle. This puzzle is solved by miners and the first one to find a solution gets the reward. This has led to a lot of competition and situations where people are building larger mining farms. According to Digiconomist, Ethereum consumes about terawatt-hours of electricity per year, which is comparable to that of Netherlands and more than what Philippines or Pakistan use.
A single transaction on Ethereum is equivalent to the power consumption of an average US household for over nine days. Advertisement A single Ethereum transaction also equals the energy consumption of more than 1,50, Visa card transactions.
The more computational power you have, the easier it becomes to mine a coin. This computational power is also referred to as hash rate. This has also made crypto mining centralised. Imagine several big players coming together, combining their hash rate and eventually teaming up to increase their chances of mining a new block and thus collecting a reward.
Small crypto miners are left at the mercy of such big players. To address these issues, a new consensus algorithm was needed that is better than Proof-of-work. Advertisement Staking coins In , a user of a Bitcoin talk forum Quantum Mechanic proposed a new idea of ending competition between crypto miners. This was called Proof-of-stake PoS. Rather than competing against each other for a block, PoS uses a process in which one node is chosen randomly to validate the next block.
Advertisement The terminology is slightly different here. To become a validator at PoS, users are required to deposit a certain amount of cryptocurrency as a stake— like a security deposit. The bigger the amount of stake, the more chances users have to mint a new block. Crypto miners have the potential to update and verify transactions, and there is a possibility that a transaction that never happened or a fraudulent transaction can be verified as well.
This is where the stake comes in. Validators will lose a part of their stake if they approve any fraudulent transactions. But what happens if the majority of the stake is bought in a network by a single entity, and worst, what if the entity starts approving fake transactions. This is called a 51 per cent scenario. If a single miner or group of miners can obtain 51 per cent of the hashing power, they can effectively control the blockchain.
