What is a Blockchain?

A blockchain is a distributed database or ledger shared among a computer network's nodes. They are best known for their crucial role in cryptocurrency systems for maintaining a secure and decentralized record of transactions, but they are not limited to cryptocurrency uses. Blockchains can be used to make data in any industry immutable—the term used to describe the inability to be altered.

Because there is no way to change a block, the only trust needed is at the point where a user or program enters data. This aspect reduces the need for trusted third parties, which are usually auditors or other humans that add costs and make mistakes.

Types of blockchain

  1. Public Blockchain: Among all types of blockchains, public blockchains are the most used types. They allow everyone to join the network and are fully decentralized. It has a transparent digital ledger that can be accessed by anyone without any restriction or permission. Public blockchains facilitate users for open participation and equal merits to validate and authenticate transactions to the chain. Every user in the network keeps a copy of the entire Blockchain along with security and redundancy.

  2. Private blockchains: Private blockchains only allow participants with authorized and validated information. This works as a distributed ledger technology operating in a restricted network, a selected group of participants, and with limited access. Private block chains permit organizations to have more control over all the data and processes making them compatible with industry regulations and other policies.

  3. Hybrid blockchain: Hybrid blockchain is among the types of Blockchain networks that is an amalgamation of public and private Blockchain networks. It comprises the best of both networks enabling decentralization, transparency, and immutability similar to public Blockchain. The Hybrid Blockchain network also has some elements of private blockchains such as faster transaction processing and enhanced privacy.

  4. Consortium Blockchain: The Consortium Blockchain network works as a distributed ledger technology comprising the benefits of both private and public blockchain networks. In this network, a group of trusted and pre-chosen participants including organizations, companies, or government entities create a network to maintain and authorize the blockchain collaboratively. Unlike public Blockchains that are open to everyone and private blockchains regulated by a single entity, the Consortium Blockchain network provides a middle way. It allows consortium members to share confidential data securely while continuing transparency and decentralization.

Uses of blockchain

  1. Money transfers: The original concept behind the invention of blockchain technology is still a great application. Money transfers using blockchain can be less expensive and faster than using existing money transfer services. 

  2. Financial exchanges: Many companies have popped up over the past few years offering decentralized cryptocurrency exchanges. Using blockchain for exchanges allows for faster and less expensive transactions.

  3. Lending: Lenders can use blockchain to execute collateralized loans through smart contracts. Smart contracts built on the blockchain allow certain events to automatically trigger things like a service payment, a margin call, full repayment of the loan, and release of collateral. As a result, loan processing is faster and less expensive, and lenders can offer better rates.

  4. Insurance: Using smart contracts on a blockchain can provide greater transparency for customers and insurance providers. Recording all claims on a blockchain would keep customers from making duplicate claims for the same event. Furthermore, using smart contracts can speed up the process for claimants to receive payments.

  5. Real estate: Real estate transactions require a ton of paperwork to verify financial information and ownership and then transfer deeds and titles to new owners. Using blockchain technology to record real estate transactions can provide a more secure and accessible means of verifying and transferring ownership. That can speed up transactions, reduce paperwork, and save money.
