What is Blockchain?

Blockchain might look difficult at first glance but the core concept of Blockchain is very simple. To first understand what blockchain is we must know what a database is; as blockchain is a type of database.

The collection of information stored in a computer system electronically is called a database. Databases store information or data in a tabular format to keep it structured, easy to search and filter.

For blockchain, the information is collected in the form of groups; they hold the sets of information and are known as blocks. Every block has a certain storage capacity. These blocks fill up and get chained up together, forming a chain of data thereby, giving it a name, blockchain.

This decentralized system does not depend on the government or banks for the transactions to complete. The blocks of information are distributed on different computers all across the globe. Blockchain can be either private (based on permissions) or public (permissionless).

If you wish you can also find a blockchain app development company in India for your business and get high-quality and scalable decentralized applications. Blockchain records all cryptocurrency transactions and adds them in chronological order.

Alteration of data present in the block is not possible and this irreversible nature for the block makes it the perfect technology to be used. A unique ‘hash’ assigned to every block allows it to move when required. For complete security and accountability implementation of IoT and Blockchain is always suggested.

What Is Bitcoin?

Making a transaction using 16 characters long encrypted addresses, Bitcoin is a type of electronic digital currency released in the market by Satoshi Nakatomi. Satoshi Nakatomi released bitcoin as open-source software in 2009. Although, monitoring the circulation of the Bitcoin amount in the market is not available and hence, there are no central figures. A peer-to-peer (P2P) network can be used to transfer the Bitcoin easily which is added to the chain of available information.

It is not possible to receive Bitcoin as easily as it sounds. Either mining or buying from other online traders are the only available options for the people.
