WHAT IS THE DIFFERENCE BETWEEN PROOF OF WORK AND PROOF OF STAKE? |

WHAT IS THE DIFFERENCE BETWEEN PROOF OF WORK AND PROOF OF STAKE Proof of Work PoW and Proof of Stake PoS are both consensus mechanisms that help keep the blockchain secure and add new transactions on the blockchain A consensus mechanism is a way in which the nodes agree on the authenticity of transactions that have been recorded in the blockchain Proof of Work PoW this is a consensus mechanism whereby nodes computers compete to be the first to solve a complex computational problem try to guess the “hash number for them to come up with new blocks and add them on the blockchain The miner who comes up with the block is then awarded with new coins Check out my blog on Mining PoW here Proof of Stake PoS this is a consensus mechanism whereby a node stakes a certain amount of the native cryptocurrency for them to validate transactions and create new blocks This crypto that they ve staked acts as collateral for them to participate as validators The chances of a node being selected as a validator depend on the amount they ve staked Once the validator is choosen to come up with the new block they are awarded a portion of the gas fees transaction fees The purpose of introducing proof of stake was to combat environmental challenges that were being caused by Proof of Work The differences between proof of work and proof of stake are In PoS the block creators are known as validators they check the transactions verify the activity vote on outcomes and maintain records In PoW the block creators are known as miners the miners work to solve for the “hash then they are awarded with a coin In PoS for you to become a validator you only need to own enough tokens or coins to stake The use of stake promotes I Decentralization this is because validators are chosen according to their stake in the network rather than computational power It ensures decentralization since you do not need high computational power to participate as a validator II Security since the validators have a financial stake in the network they will act in the best interests of the network In PoW for you to become a miner you must invest in equipment and energy to power the computers solving the computations This makes PoW less accessible to individual users and more dominated by large mining pools with access to economies of scale PoS systems are more energy efficient as compared to PoW this is because you need less computational power as compared to PoW systems One of the downsides of PoS is that an entity or a group of people can decide to acquire a significant portion of total stake in the network thus causing some form of “centralization Which can enable them to have a level of influence on the network as they will have a greater probability of being chosen as validators therefore having more opportunity to earn rewards However there are mechanisms that are in place to prevent validators from acting maliciously against the best interest of the network e g slashing Slashing is a mechanism where validators who might have violated the rules of the network have a portion of their stake confiscated Thank you Don t forget to check the rest of my blogs if you d like to learn more about blockchain and web Cover image by bitpay |
