Hello fellow steemians. It weekend and i hope y'all had great week. This is something educative that i think is good i share it with you guys. Actually i want to talk about blockchain it types and it uses. We have been hearing a lot about it, so i thought to it that is good i talk about it.

Blockchain can be defined as a decentralized type of data that can't be tampered or altered and it's informations are secured. It is a layer of blocks where by each block points or relates to the previous block. This nature of it makes it hard to tamper with. The blocks are chained by a unique or special identifier in the form of cryptographic hashes. Information on a blockchain can be shared with any one but can't be easily altered or tampered with by any person. In case any individual tries to tamper other users are quickly alerted.

THE TYPES AND USES OF BLOCKCHAINS
There basically three(3) types of blockchains.
These are;

• PUBLIC BLOCKCHAIN
• PRIVATE BLOCKCHAIN
• FEDERATED BLOCKCHAIN

I will begin to talk about the public blockchain.

A public blockchain is the type of blockchain which is commonly known and can be used by anyone without any restrictions. The dapp and most of the cryptocurrencies we use works on a public blockchain. They are easy and simple to use by any individual. Individuals who joins a public blockchain can contribute to it growth and gets rewarded for their contributions.

USES OF THE PUBLIC BLOCKCHAIN

They are mostly used for cryptocurrency trading and mining. It distributes it nodes to all it users that allows them to create new blocks.

Also public blockchains can be accessed by anybody on the internet,it is regarded as limitless.

Private blockchain; a private blockchain is the type that allows only recognized or selected individuals to have access to it. That is to say that it is restricted to some particular group of people which renders it to be centralized or governed by a central unit, even though it works on as a chained unique codes. This type of blockchain is mostly used by organisations or businesses. Which helps them to keep their informations safe.

<USES OF PRIVATE BLOCKCHAIN

The private blockchain does not allow any individual outside a specific group of people on the blockchain to have access to it.

It prevents an organization's privacy from outsiders having access to it.

Federated blockchain; this type of blockchain is the type of blockchain that is owned or managed by multiple users with a special unit that solely controls it. It's chained unique codes are being managed and can be changed at any given point in time by the special unit. They serve as the governing body.

USES OF THE FEDERATED BLOCKCHAIN

With the federated blockchain, it validator nodes can receive and initiate transactions easily.

It's decentralized nature renders it with a very high security level.

In, conclusion a blockchain is a form of information that can't be tampered with no matter what. Also the blockchain is in a chained unique codes that depends on one another.
