Digital currencies and online transactions are well known for their risk-free and easy to use dashboard, also the payment is secured, and the system is decentralized in the case of Cryptocurrencies.
We are very aware of its advantages and fair use of online resources, the effort you put in is less and income is more, but we can also not forget that everyone can’t be perfect, it may look perfect, but everything has some imperfection.
So does Cryptocurrencies, therefore, to save the problem comes PoW or (Proof-of-work), In our today’s cryptocurrency blog we will specify the meaning and significance of this term and would focus on its relevancies.
What is PoW (Proof-of-work) Algorithm?
PoW is an algorithm that works as a shield for cryptocurrency mining and transactions, we have been exposed to some horrible attacks like Double-spending attacks and mining scams in our past blogs. To know more about bitcoin trading, you can read this article .
Therefore, we can conclude that even Cryptocurrency is not the safest way for transactions. In History, lots of scams and online attacks have happened during the transaction of cryptocurrency.
PoW was a feasible idea that was brought into the light by Hal Finney in 2004 which keeps an eye over the fair use of cryptocurrencies and restricts malicious attacks like sending spam requests online and other vectors which can directly breach the protocol of Cryptocurrencies.
How does Proof-of-work work?
The first cryptocurrency that made use of the PoW algorithm is Bitcoin, as it is the first cryptocurrency that has gained major popularity as an investment asset, forming a foundation of conditions for acceptance of Proof-of-work and its continuation.
It uses the SHA-256 algorithm which directs the use of hash power and incentivizes the winning mining pool based on their mining record and performances like the proportion of verified transactions and Honest mining at a faster rate.
Conditions for Proof-of-work
Proof-of-work works on some special conditions that help in validating the transaction done by the miners, here are some conditions that are followed during the Application of proof-of-work:
- Generation of PoW in Every Ten Minutes
There is a high level of competition during the mining process, and it takes an average of 10 minutes to produce a valid Proof-of-work by the miners which are compulsory to stay in this marathon of finding a block.
- No Monopoly during mining
Also, Proof-of-work restricts the monopolization of resources and the hash power that is dominated by the larger mining pool, due to which Small mining pools get encouraged to mine more blocks.
Requirement of Proof-of-work for Cryptocurrencies
Here is the reason why a cryptocurrency needs validation in form of Proof-of-work and why it is necessary to have an acceptable Proof-of-work:
- To achieve Consensus
Proof-of-work ensures the consensus among the transaction and a mined block, it helps to make a system decentralized and neglects all the dominating factors.
- To achieve Security
Proof-of-work provides security of transactions made by applying the complicated algorithm of verification that is so tiresome that no security breaking and breaching of the protocol can take place.
- More Resource-oriented
As we have already discussed, it restricts the alteration in the input of transactions and records, therefore it helps to save the overconsumption of resources and proper uses of computation power is ensured.
- For Attack-resistance
Many hackers and ransomware methods try to gain profitability from crypto mining in illegal ways, therefore, to put an end to such illegal attempts, It is necessary that Proof-of-work must be applied over the cryptocurrency transaction.
