Cryptocurrency Explained: What Is Bitcoin?

Bitcoin is the world’s first decentralized digital currency. It is also considered as the father of all cryptocurrency. The white paper was published by the founder of Bitcoin, Satoshi Nakamoto, on 31st October 2008. Initially, he used the word shorter coin. It was first launched on 9 January 2009.

Bitcoin is an open source system. Its design is public. Nobody owns or controls bitcoin technology, and everyone can take part in its development and enhancement. Blockchain is the core technology behind it. Blockchain is a combination of cryptography and algorithm code. The first block is known as genesis block. It works on peer to peer technology, done via mining which is called Proof of Work.

The cryptography hash algorithm used is called double SHA-256. When a miner discovers a block, the winner is rewarded with a certain number of bitcoins, presently the reward is 12.5 bitcoins. This value will halve every 210,000 blocks. It typically takes four years for the same. This is how new bitcoins are created.

The blocksize of a bitcoin is 1MB. It takes about 10 minutes to mine a block. Bitcoin is capable of processing 3-7 transactions per second. Subunit for bitcoin is Satoshi and the smallest fraction of bitcoins is 8 decimal. The total supply of bitcoin is 21 million.

Bitcoin has been forked multiple times. Some were successful, while some are dead. There are two type of forks, hard forks and soft forks. During a hard fork, software, hardware implementations and its mining protocols and procedures are upgraded. Once the user is upgraded, It aborts all transactions from the previous software. And, a new branch of blockchain is created. It is segregated from the parent blockchain.

A soft fork is a change to the Blockchain protocol, wherein only previously valid blocks/transactions are made invalid. New transaction types can often be added as soft forks.
