What is Blockchain Mining in 2020? [Complete Explanation]

About Blockchain Mining

Blockchain mining is a process to validate every step in the transactions while operating bitcoins or other cryptocurrencies. The people involved here are known as blockchain miners, and these miners’ function in a labyrinth of computational hardware and software — their primary aim to authenticate the transfer of currency from a computer in the network to another.

Blockchains are so-called because of their ‘blocks’ and ‘chain’ structure. The blocks are composed of numerous bitcoins which are individual units that store all the data code individually. The chain refers to the links from one neighbourhood block to another. Each blockchain represents a specific code authentication explicitly encrypted on the network software.

The process is rewarding, as well. A single user does not handle the mining process, but a number of them compete on a unified authentication to get the rewards. Each mining success comes with a bonus of several bitcoins.

The Mining Process

The encrypted data needs decryption to prove validity. Decrypting the data encoded in blocks is not an easy task and demands computational hardware and software alongside human efforts. One single code decryption will take an enormous amount of time and energy both for the computer and the human.

A combination of the computational speed and human intelligence will result in the decrypted data, which, when linked with the adjacent blocks, verifies the transaction. The bitcoin blocks link together by codes named hash-codes. These hash codes meet specific requirements in the encrypted data’s solution.

The miners need to solve the complex problem to find the perfect solution hash that matches and fits. The solution to the hidden code encryption is known as the ‘Proof-of-work.’ As the name suggests, it is a proof of the abundance of resources, time, and energy that is spent by the miner. This proof-of-work is challenging to produce and may sometimes prove to be of lower profitability.

Types of Mining

With the complexity of resources and work involved in the mining process, it is not feasible to work with a regular desktop or PC. The blockchain mining process demands unique sets of computer hardware and software that will match the expertise in demand.

It is not a single man’s or computer’s work. When these two will combine, the intelligence and data decryption speeds will unite to work on a single transaction process authentication. It would help if you had a custom mining hardware and software that is specifically designed to mine the blocks. Get into a mining pool and then get access to the bitcoin wallet. Your wallet needs to be secured to prevent fraudulent transfer of rewards obtained on mining the bitcoins.

The mining process can be undertaken either individually, in a group or, by cloud mining.

1. Individual Mining

In Individual Mining, the user has to register itself as a miner. As soon as a transaction occurs, all the single users in the blockchain network will receive a mathematical problem. The first one to solve the complex mathematical problem gets rewarded. The solution comes after rigorously using the hardware and software properties of the computer, which is being used by the miner.

With the solution onboard, all the other network miners will validate the decrypted value and then add the same to the blockchain. Thus, verifying the transaction that just occurred.

2. Pool Mining

Another type of mining is Pool Mining, where several users operate together to approve the transaction. Numerous transactions occur every second. Sometimes, due to the complexity of the data encrypted in the blocks, a single user can’t decrypt the data encoded. Then the entire team of miners in the network operate together to solve the complex numerical and computational problem. After the result is validated, the reward is then also split between all users.

3. Cloud Mining

Eliminating the use of multiple computer hardware and software, another way in which you can mine blockchain is through cloud mining. Without juggling with the hardware and software parameters, electricity, or power usage and the connectivity or bandwidth issues, you can extract the blocks hassle-free with this method.

Cloud mining allows the users to operate in peace, not having to worry about the heating of the equipment or ventilation issues in managing the hardware. The constant worry to deal with handling all the machinery and worrying about its order timings or selling profits is eliminated altogether.

It seems profitable, according to the mining hardware parameters, but has its own set of disadvantages. These include limiting operational functionality with the limitations on bitcoin hashing. Lowering the reward profits results in the operational expenses to increase with cloud mining. The software up-gradation gets restricted with this type of mining, and so does the verification process involved.

Use of Blockchain Mining

1. Validating Transactions

Bitcoins are decentralized digital currencies, which are managed on a peer-to-peer computer network and transferred from one user to another. Bitcoin transactions occur in huge figures daily. But there is a certain lag in the entire framework.

Since these cryptocurrencies operate without a central administrator, there is a substantial amount of insecurity with the transactions that transpire. While dealing with printed currency, the validation lies in the printed numerical codes in each of them. Accordingly, what is the authentication with such cryptocurrencies?

With each transaction, blocks are added to the blockchain. The validation lies in the mining results from the blockchain miners.

2. Confirming Transactions

Bitcoins get embedded in the blockchain network, encoded explicitly in the blocks. A transaction takes place in the bitcoin networks that are present in the blocks.

Miners work the blockchain mining process to confirm whether the transaction is authentic or not. Transactions get confirmed on completing the inclusion in the block.

3. Securing Network

Bitcoin Miners work together to secure the transaction network. Network security increases with the increase in the operators mining the blockchain.

The decentralized network makes it difficult to account for responsibility to anyone in case of an attack or duplicity or cheating activity. Network security ensures no fraudulent activity is undertaken with the cryptocurrencies.

Conclusion

A process in verifying transactions using blocks and chains, with the combinational commitment of computational activity and human intellect, the blockchain mining has fastened areas toward validating specific methods and securing network transactions. 

There is always a possibility of threats in losing the funds while managing cryptocurrencies. With the availability of different mining processes, these miners (working either individually or in a group), now have increased options. Operating with the primary aim to authenticate deliveries in bitcoin transactions, the miners accomplish every detail of the encrypted code.
