Bitcoin is the firstdigital currency introduced without any central authority. It is known as virtual currency or cryptocurrency. It was introduced in 2008 and launched the next year. Satoshi Nakamoto, the name used by the apparent pseudonymous person developed bitcoin, the future of e-commerce. He is referred to as a very mysterious character in the history of developments. As society advances towards a digitally enveloping arena, online transactions have become an integral function. We had to depend upon the third party or banks for the online transaction of funds. Bitcoin usage has cut off the intermediaries and made transactions effort-less with negligible or no fees.
UNDERSTANDING BITCOIN- WHAT AND HOW?
It is a computerized coded system, used as a virtual currency to make online transactions. There are no physical structures or forms of Bitcoins, they are computer files stored in digital wallets. The wallets can be kept within one’s devise, i.e., smartphone or computer, or in banking servers. Individuals can also send Bitcoins over the internet and exchanging them is legal as well.
When a Bitcoin is owned by an individual, they can either use it to make a purchase or send it to another individual. In both cases, there is a transaction taking place between devices. These transactions are authorized by digital signatures. With the help of authorization these transactions are verified (usually within minutes, whereas it takes longer when banking institutions are involved). After verification, the transactions automatically get saved in digital ledgers, also known as blockchains.

To understand the working of the bitcoin system better, one requires to understand what is a blockchain? A blockchain collects information or data from all the transactions entered together in groups. These data are filled in blocks, that hold a specific capacity of information. When one block goes beyond it said limit, it is attached to the block filled right before, forming a cluster of information also called the “blockchain.”
Bitcoins are computer-coded strings of data formed into files. So, during transactions, instead of making it complicated for the users by typing out complex strings of characters it uses keys. Bitcoin balances are associated with public addresses which can be viewed on blockchains, it keeps a track of all the transactions. Most bitcoin addresses appear as QR codes.
The bitcoinaddresses make transactions user-friendly. There are two types of bitcoin address- the privateaddress is used to send andbitcoinpublicaddressused to receive bitcoins. The key is so significant that it should be known only to the person who owns the bitcoins. The bitcoinaddress is the main identity of a user owning the digital currency.
WHAT IS BITCOIN MINING?
Just like a company owns thousands of computers that operate within a single server, under one roof, to store and access all the data concerning that company. Similarly, bitcoin is a system with thousands of computers (also called nodes). The operators of these computers spread across geo-political boundaries are called miners.
Mining involves the step of verification of transactions. This requires the miners to solve computerized equations or puzzles. When the verification is complete, and the data is considered legitimate, it is added to the block. The completion of blocks and adding them to blockchains renders miners’ rewards.
There is a limited number of bitcoins present in the world market. The more the miners that participate the harder it is to mine. The number of bitcoins released in each interval has decreased. Due to the finite supply of bitcoins, there are only 21 million bitcoins left to be mined. Henceforth mining all of them, the world market of bitcoins will exhaust. Since bitcoins launched, 18.5 million of them have been mined.
Initially, when bitcoins were released, the reward was 50 bitcoins. It decreased over time, as participants in finite grew and the number of bitcoins left to be mined. Now the rewarded miner gets 6.25 bitcoins. The current value of 1 bitcoin is 52,210.50 US dollars. The exchanging value of bitcoin has gained popularity among todays’ investors.
