The Proof of Stake algorithm works on the communication between unknown peers in a distributed network of users of the system. After confirming transactions, this mechanism broadcasts information among all nodes of the blockchain. This process ensures that transactions are carried out in a trustless manner and that each new block added is a trusted block.
Decentralization lies at the heart of blockchain technology and cryptocurrencies. There is no single person or authority managing the transaction record and data of the blockchain network; instead, the network relies on an army of actors and participants to validate incoming transactions and add them as new blocks to the chain.
Proof of Stake is a consensus mechanism that helps select participants to succeed in this profitable activity. You may be wondering how this process leads to profitability?
If the chosen individuals can correctly verify new data and transactions and are not trying to cheat the system, they are rewarded with cryptocurrency. That’s why the process can be profitable.
When participants in a blockchain verify that a transaction is legitimate and add it to the blockchain, we say that the participants have reached consensus.
With a proof-of-stake algorithm, participants, called validators, stake a certain amount of cryptocurrency or token. For example, they lock their stake in a smart contract on the blockchain. Now, these individuals have a chance to validate new transactions and earn a reward; but if they unprincipledly verify fake data, they may lose some or all of their stake as a penalty.
Consensus algorithms include:
• Proof of Work
• Delayed Proof of Work
• Proof of Stake
• Delegated Proof of Stake
• Proof of Authority
• Proof of Burn
• Hybrid combination of Proof of Work [PoW] and Proof of Stake [PoS]
How does a Proof of Stake [PoS] consensus protocol work?
A Proof of Stake algorithm achieves consensus by requiring users to stake a portion of their tokens. These users then have a chance to be selected to validate blocks of transactions and receive a reward for doing so.
Each PoS network can implement the algorithm in different ways. However, blockchains are generally protected by some form of random selection. This process involves taking into account the wealth of the node, the age of the coins and tokens (the time they have been staked or locked), and the randomization factor.
To be more specific, the validator in the proof-of-stake algorithm is limited to validating a certain number of coins based on their value. For example, someone who claims to own 3% of all Bitcoins can only validate 3% of new blocks. As a result, the more coins or altcoins a validator owns, the higher their validation power will be.
The validator of another block in the proof-of-stake consensus algorithm is selected in a semi-arbitrary, two-stage process. The main component to consider in this selection method is the customer stake. Each validator must have at least one customer stake in the blockchain system to be eligible to perform the process.
The more shares a person has, the better their chances of being selected as a validator, as they will have more money and capital in play. It is worth noting that taking malicious actions against people with fewer shares will lead to large losses.
