What is Proof of stake?
Proof of stake is similar to Proof of work. Both are used to attain consensus and keep the underlying blockchain secure. But there is one important difference Proof of stake requires far less work to validate data blocks and thus requires less energy. In Proof of stake, there is no race against the nodes to validate a transaction instead they now take part in a lucky draw whose winner is decided by the blockchain itself. The winner then confirms the action and gets a very small reward for using very little electricity.
Then how do we know that the winning node won’t cheat and validate a wrong transaction? Well to volunteer in this lucky draw you have to stake some of your cryptocurrency into storage if you cheat you are penalized. Some of your stake money is being taken over by a fraudulent business. In fact to keep the lucky draw fair the more crypto you stake the higher your chances of getting picked as the winner. However, it’s still randomized let’s have a deeper look into how this works.
How Proof of Stake Consensus work
The Proof of Stake method selects a node to be the validator of the next block using a pseudo-random election process based on a combination of parameters such as staking age randomization and the node’s wealth. As the Proof of Stake name implies nodes on a network stake a certain amount of cryptocurrency to become candidates for validating new blocks and earning the fee associated with them.
The node that will validate the new block is then chosen by an algorithm from a pool of candidates. To make the selection fair to everyone on the network this algorithm mixes the amount of stake with other considerations. It is noteworthy that the blocks and stack proof systems were fabricated rather than mined. Proof of Stake cryptocurrencies frequently begin by selling pre-mined coins or they begin with the proof-of-work method and then move to proof-of-stake.
Whereas with proof-of-work-based systems more and more cryptocurrencies are generated as an incentive for miners. The proof of stake method typically pays miners with transaction fees. The two most popular techniques that Proof of Stake systems use to choose their validators are known Randomized block selection and Coinage selection.
Randomized block selection
The randomized block selection technique chooses its validators by looking for nodes with the lowest hash value and the highest stake. Because stake sizes are public the next forger can typically be predicted by other nodes.
The coinage selection technique selects nodes depending on the length of time that their tokens have been staked. The age of a coin is determined by multiplying the number of days the coins are placed on the stake by the number of coins placed on the stake. After a forging block, a node’s currency age is reset to zero and they must wait a specific amount of time before forging another block. This prevents large stake nodes from controlling the consensus mechanism.
Proof of Stake Node
Each cryptocurrency that uses the proof of stake algorithm has its own set of rules and procedures to create the best possible combination for its respective ecosystem. When a node is selected to create the next block it verifies the validity of the transaction in the block it signs and adds to the blockchain. The transaction costs link the transactions in the block are paid to the node as a reward if a node wants to stop foraging its stake and earn rewards will be returned after some time allowing the network to verify that the node hasn’t added any fraudulent blocks the blockchain.
What are consensus mechanisms?
What are consensus mechanisms? proof of work and proof of stake are both consensus mechanisms which are methods for maintaining the integrity of a blockchain. Consensus is what solves the problem of double-spending. If a cryptocurrency trader could spend coins more than once the entire system would be jeopardized and susceptible to theft. This is a difficult challenge to solve especially with online currencies that lack a central authority such as a bank or government.
Security of Proof of Stake
The Security of Proof of Stake. The stake in proof-of-stake acts as a financial incentive for the forger node to avoid validating or initiating fraudulent transactions. If a fraudulent transaction is detected by the networks the forger node will lose a portion of its stake. As well as its right to participate as a forger in the future.
As long as the stake is more than the reward the validator will lose more coins in the event of a fraud attempt. A majority stake in the network commonly known as the 51 attacks would be required to successfully control the network and forcefully accept fraudulent transactions hence this acts as a security feature for the proof-of-stake algorithm.
Features of Proof of Stake
Features of Proof of Stake. Proof of Stake algorithms has three fundamental features no matter how they are adopted in an ecosystem.Read more about Top 5 Metaverse Crypto Coins.
Fixed number of coins.
There are only a finite number of coins that circulate through the network at any given time. The possibility of creating new coins does not exist the network either starts with a finite number of coins or it starts with proof of work to bring coins into the network and then switches to proof of stake.
Transaction fees as a reward for forgers.
Each transaction has a fee attached to it this is gathered and given to the entity that will create the new block. If the forged block is proven to be fraudulent the entity loses the transaction fee as well as a stake this is known as slashing.
The impracticality of the 51 attacks.
The 51 per cent attack is impractical because it requires the attacker to own 51 of the total coins in the expensive network. As a result, carrying out the attack is too time-consuming costly and unprofitable.
Advantages of Proof of Stake
Advantages of Proof of Stake energy-efficient is conserved since nodes aren’t competing for the right to add a new block to the blockchain. Furthermore, no advanced mathematical problem must be solved unlike in a proof of work system saving energy is truly decentralized. In proof-of-work blockchains, an additional incentive of exponential rewards is offered to join a mining pool resulting in a more centralized blockchain. In a Proof of Stake system rewards are proportionate to the amount of money invested. As a result, joining a mining pool delivers no further benefit in promoting true decentralization.Read more about What is Solana Coin.
Disadvantages of Proof of Stake
Disadvantages of Proof of Stake validators with a large stake can create an oligopoly if a group of validator candidates get together and hold a big amount of total cryptocurrency that is in circulation. They will have a better chance of becoming the actual validator. Increased chances mean more possibility of earning higher rewards which leads to the acquisition of a large currency share.
As a result, the network may grow more centralized over time. The problem of nothing at stake in the event of a blockchain split or forking this problem outlines the nodes suffering little to no disadvantage if they support several blockchains. In the worst-case scenario, each fork will result in many blockchains and validators and the network’s nodes would never reach consensus.
