The world of crypto is filled with many things we need to know. Today I want to talk about PoW abd PoS. Many of us still dont know what it is.
For a clearer understanding of what it is we first need to understand what a blockchain is. Knowing and understanding a blockchain will help us to understand Pow and Pos better.
Now let us dive into business.
Blockchain
A Blockchain is a chain of blocks , with each block containing a list of transactions and with cryptographic hashes this blocks are linked together, creating a immutable and tamper-proof record of all transaction.
In a clearer sense we can say of a Blockchain to be a decentralized digital ledge technology that enables the secure and transparent recording of transaction across multiple computers or nodes.
It is decentralized in the sense that it has no central authority instead it enables a Peer-to-Peer transaction ans eliminates single points of failure. A blockchain being decentralized help increase resilience and reduce the risk of censorship or control by a single entity.
Blockchain technology is built up with applications that serves beyond cryptocurrencies. Some notable blockchain use case include identity verification, healthcare data interoperability, smart contracts and supply chain management.
In a Blockchain there are two different consensus mechanisms used to validate transactions and also to secure the network.
This consensus mechanisms ensure that all nodes in the network comes to habe an agreement on the order and validaty of transaction which help in maintaining the integrity and security of the blockchain.
There are many consensus algorithm which are used in a blockchain but we wilk discuss about two; the PoW and PoS. This are two different algorithm
PoW and PoS
PoW is a consensus algorithm that was introduced with the creation of Bitcoin which happens to be the first cryptocurrency. So it is the original consensus algorithm. In order to add new blocks as to the blockchain in a Pow system, miners compete to solve complex mathematical puzzles. The need to invest computational power and energy into solving these puzzles and anyone who comes first in finding the solution broadcast it to the network for verification. In this process once the solution is verified by other notes the miner who found the solution receives newly-minted cryptocurrency and transaction fees.
PoS is a consensus algorithm where validators are chosen to create and validate new blocks based on the amount of cryptocurrency they hold. This is quite different from the Pow algorithm where miners solve mathematical puzzles in order to add new block.
In a Pos system, validators are selected to create new blocks and validate transactions based on their stake which in a way represent their ownership or investment in the cryptocurrency.
The higher the stake hold by a validator the higher the chances of being selected to create the next blocks.
Finally
Consensus mechanism are very helpful to The blockchain technology. The two main algorithm I discussed are both are very important and are the most used algorithm. The Pos organism has more energy efficiency compared to Pow because it does not require a vast computing power.
Now i believe you'v understood Blockchain and the two main algorithm which are Pow and Pos.
