Over the past few years, Bitcoin has gained quite a lot of popularity. People across the world are literally using it for investment purposes. There are some classic models of the existence of cryptocurrency. It is a reward that maintains the blockchain networking. Blockchain networking is a ledger of decentralized. To maintain the blockchain along with getting the cryptocurrency is known as mining. It demands the better performance of the hardware. 

However, there are still a few things that are missing in the model. Talking of which it is the method and consensus mechanism that needs to be worked on. The consensus is focused at reaching a fair deal amongst the parties that are involved. It does all the crucial things that make sure the validity of the next block is possible in the blockchain. It also focuses on solving the problem called the Byzantine Generals which is quite common in the system of decentralized peer-to-peer currency. 

There are some networks if cryptocurrencies and blockchain which are now relying on the proof of work mechanism. It strives for adding another block in the chain for solving the issues and problems. the one that achieves and solves it first gets awarded for the efforts in the mined coins. Its principle is simple. It is called the longest chain winner. This shows that the chain that comes with better productive miners would grow at a faster pace and is extremely reliable too. 

Different Algorithms that are used: 

But this does not change the fact that different blockchain’s uses other mining algorithms. They depend on the similar consensus way. One of which is the PoW mining algorithms SHA-256. It is one classic bulletproof hashing algorithm with a significant con – ASIC-tolerance. Other than this, Ethash is a PoW-based hashing algorithm that is used in the Ethereum network. Lastly comes the CryptoNight which is a hashing algorithm introduced by the Bitcoin developers. It offers better security and network privacy. 

But the world of cryptocurrency is never constant. There will be more hashing algorithm that would appear in this field. There are so many other new algorithms as well that depends on the mechanism of the Proof of Work consensus. However, the trending one is the PoW based which offers scalability and privacy. Grin coin and its hashing algorithm called MimbleWimble is the finest example of the same that offers high level of security, privacy, and scalability.
