Definition : What is Blockchain ?

Blockchain is a process in which you store data and information in a way that is impossible to change or hack. The blockchain might be a form of database that contains data blocks that are connected together.

Types of Blockchain:

The following are the four categories of blockchain:

Public Blockchain

Anyone who has internet access may transmit payments and become a member on a public block-chain, which has no access restrictions. Typically, such networks provide monetary rewards to individuals that protect them and use a Proof of Work technique. TechPay and bitcoin are the two most well-known public blockchains.

Private Blockchain

Private Blockchains require authorization to join, and you cannot do so without the network administrator’s consent. Access to participation and verifications is restricted. Private Blockchains are usually known as Distributed Ledger (DLT) to separate them from other peer-to-peer decentralized database systems that are not even accessible to an ad-hoc computing cluster.

Hybrid Blockchain

A hybrid blockchain combines the benefits of both centralized and distributed blockchains. The chain’s exact operation depends on the parts of centralization and decentralization that employs used.

Side Blockchain

A side chain is a blockchain database that operates concurrently with a core of blockchain. Transactions from the main blockchain can be connected to and from the side chain, allowing the side chain to function independently of the main blockchain.

Application of Blockchains :

Money transfer

Money is sent through blockchain, which is less costly and quicker than using traditional payment services. Unlike cross-border operations, which are both time-consuming and costly. Unlike the US banking markets, which take days to move money, blockchain money transmission is simple.

Financial exchange

Nowadays, businesses employ decentralized cryptocurrency exchanges. They receive faster and cheaper transaction by using blockchains specially Techpay, and the decentralized exchange doesn’t need investors to transfer their funds with a centralized government.


The block-chain is used by investors to operate securitized loans using smart contracts. Some events, including as consumers can buy, a margin call, complete repayment of the loan, and collateral discharge, can be automatically activated by smart contracts created on the block-chain. As a result, loan servicing is quicker and cheaper, and lenders are able to offer better rates.


Clients and insurance plans can benefit from more openness by using smart contracts on a blockchain. Customers would be prevented from filing repeated claims for the same occurrence if all claims were recorded on a block-chain. Furthermore, the use of payment systems can expedite the payment procedure for applicants.

Investing in real estate

To verify accounting reports and administration, as well as transfer deeds and titles to new owners, real estate deals need a large amount of documentation. Using block-chain cameras to monitor real estate deals can make asset verification and transfer more safe and approachable. This can help you save time and money by speeding up transactions and reducing paperwork.

Keep your personal information safe

Keeping data like your Social Security number, birth date, and other identifying details on a shared database (such as a block-chain) may be safer than existing hack-prone solutions. In areas including travel, healthcare, banking, and education, block-chain technology may be used to safeguard access to identifying details while also enhancing access for those who need it.


If personally identifying data is stored on a block-chain, we are only a step away from being able to vote using block-chain technology. Nobody can cast a ballot, only qualified voters may vote, and votes cannot be manipulated if block-chain technology is used. Furthermore, it can broaden voter participation by enabling voting as easily as tapping a few buttons on a cellphone. Simultaneously, the cost of holding an election would be significantly reduced.

Use for government

The management of government aid such as social welfare, Social Assistance, and Healthcare is another way to employ user signatures recorded on a block-chain.

Storage of data

When block-chain is used in conjunction with a data storage system, it may improve confidentiality and reliability. It will be harder to hack into and wipe away all of the information on the network since data may be kept decentralized, whereas a centralized data storage service may only have a few sources of backup. It also implies that data is more accessible because access isn’t limited to a particular company’s activities. In certain circumstances, storing data on the block-chain might be less costly.
