Blockchain For Dummies: A Simple Guide


Blockchain is the base technology on which digital tools are developed. In order to support the first Cryptocurrency i.e., Bitcoin, Blockchain was built. It is not only limited to support digital transactions and composed for world revolution.  

Though this very Blockchain word is in focus for several years now, many do not have a decent idea about it. Here is some crucial information in order to build your concept about Blockchain.

What Is Blockchain?

Blockchain is a whole new technology. It is a chain of blocks that are chained together and duly spread out to all the users. It works as a fixed record of transactions that is independent of any external authority for validating the integrity and authenticity of the data. Though the transaction is usually economic, it gives you access to store every kind of information to keep in the blocks. 

Location Of Blockchain

Blockchain is a network of computers that can be from anywhere, all over the world. The nodes are linked with each other and it is decentralized, according to bitqt app.

Blockchain And Its Types

Every Cryptocurrency is supported by its respective Blockchains. These Blockchains come with different features. Here are the details about them.

Private Blockchains

Private Blockchains are restricted ones. It has put restrictions on who can join them. That is why it is also called permission Blockchain. These Blockchains prefer to keep their transactions totally private and allows only the network participants to access the Blockchain. 

Permissioned or private Blockchains are more centralized than public Blockchains. The running body of the chain has total control over the joining in the network. Those businesses which are willing to share their data by protecting some sensitive information can opt for these Blockchains. 

Ripple and Hyperledger is an example of private Blockchain.

Public Blockchains

Public Blockchains are open-source networks that welcome everyone. Anyone can join these Blockchains as a member, developer, or user. Anyone can see and examine every transaction that is taking place in a public Blockchain. 

Public Blockchains are resistant to censorship. Being fully centralized, public Blockchains store their data on computers from anywhere globally or across the globe. So, one can not change the data on the network. 

Some public Blockchains are Bitcoin, Litecoin, Ethereum.  

Consortium Blockchains

Combining the best features of both the Blockchains, consortium or federated Blockchains are developed. It is more decentralized than private Blockchains but controls what data will remain confidential and what will be public.

Private Blockchains are fully controlled by one entity, consortiums are powered by a set of preselected nodes or entities. Here nodes are implying to devices like laptops or computers that function as servers, storing information. 

Benefits Of Blockchain

The main benefit of this Blockchain technology is that it offers the transferring and recording of data with transparency. All the information is viewable to all the members, which builds trust between the users. It also eliminates the need for the mediator, so no need to go searching for a trustworthy mediator. It can change the operating way of technology companies with its revolutionary features. 

Rules of Blockchain

The rules of every Blockchain may differ. Those rules are called the protocol. This consensus algorithm is generally explained by the creators’ of the Blockchain. Each and every computer within the Blockchain has to follow the set protocol. The protocol has a ruling authority on virtually anything. For example, the Bitcoin protocol has the rule of creating a new block every 10 minutes, and as a reward to miners while reducing 210,000 blocks. 

Some More Pointers

From the above information, you get an idea about what Blockchain is. Now it is also vital to know what Blockchain is not. Blockchain is definitely not a Cryptocurrency and cryptographic codifications. Many people think that it is a programming language or a Python library, which is totally false.
