Is BLOCKCHAIN going to be the next Internet? Tough question to answer. However the impact of this technology in different areas of life and business is increasing day by day. Anyone who is futuristic, should learn more about this and explore the possibilities.

Blockchain is a decentralized, distributed network that comprises thousands of nodes that are interconnected. Each transaction in a blockchain network is verified by all nodes and processed through in the network.


Blockchain is a technology designed to prevent tampering. With an immutable digital ledger at its heart, blockchain is the foundation of a new era of transparent, traceable accounting. This eliminates a problem that has been around in the music industry for decades. In addition, blockchain enables the use of cryptocurrencies and tokens. This allows anyone in the world to pay for music and support artists they love.

Blockchain technology is fast evolving and has the potential to affect various industries. Blockchain developers at Systango are creating innovative solutions for healthcare, insurance, finance and governance.

To work efficiently on more complex decentralised apps and smart contracts, we utilize tools that reduce build time and help in debugging the code. Here are the top 5 blockchain development tools used by our developers.

Britain will begin live testing of crypto blockchain technology for traditional market activities such as trading and settlement of stocks and bonds next year as part of a drive to become a global “crypto hub”, the finance ministry said on Tuesday.

In the cryptocurrency industry, there are various types of people.

Unfortunately, many entered the space and traded without a thorough understanding of how the transaction is documented and protected.

Today I will give you the expository of the technology on which the crypto market is based, how it works and the problem that it has come to solve.

I recommend you read to the end and find out more.


The term “block” denotes a list of records and the word “chain” clarifies the link connection between the list of records.

As in the case of one reporting file being linked to another, that is what blockchain is all about.

Blockchain technology, therefore, aims to resolve everything that has value in a way that it is impossible to make any alterations.

Also, it helps eliminate middleman interference or any form of a mediator.

This technology was adopted in 2008 by an unidentified person or group using the pseudonym Satoshi Nakamoto to record Bitcoin transactions.


Business runs on information. The faster it’s received and the more accurate it is, the better. Blockchain is ideal for delivering that information because it provides immediate, shared and completely transparent information stored on an immutable ledger that can be accessed only by permissioned network members. A blockchain network can track orders, payments, accounts, production and much more. And because members share a single view of the truth, you can see all details of a transaction end to end, giving you greater confidence, as well as new efficiencies and opportunities.


Assuming you have three blocks in front of you.

Each block contains three elements, which are data, hash, and the hash of the first block. Let me explain.

The input inside the block is the data, and these details depend on the type of blockchain.

For example, if a blockchain is dedicated to Bitcoin, it will keep a record of the activities carried out on the Bitcoin network.

A hash is a special code that represents a block and the information it contains.

Every time a block is generated, a unique code or link is created which is the hash.

The previous block hash builds the connection between the blocks, and this mode maintains the security of the blockchain.

I explain with an illustration. If you have 3 blocks and each block has a hash and the hash of the other blocks.

The hash of block1 points to block2 and block2 points to block3.

In this scenario, block 1 is extraordinary as no blocks are pointing at it, and it bears the name “Genesis Block”.

If the content of block 1 is changed, then the block’s hash will be rewritten, making block 2 and the other blocks worthless.

Because they no longer keep a legal hash of the recent block.

In today’s world, many computers are very fast at computation and can recalculate the hash of all the blocks on the network in seconds.

For this reason, blockchain implements a tool called proof of work and this makes it possible for block creation to slow down.

If any blocks are set on the line, it takes a few minutes to evaluate the proof of work before adding a new block.

This process makes it difficult to modify blocks because if you interfere with one block, you have to recalculate the proof of work for the other blocks.

Blockchain security is tied to the hashing process and proof-of-work means.

The other way the blockchain is secured is by advertising itself through the use of peer-to-peer meshes and any participant has the right to join.

Each player in the mesh has a complete replica of the blockchain and this allows the node to show that everything is in order.

Every time a new block is confirmed, it will be sent to all parts of the network, each node verifies the block and places it on its blockchain.

All participants must approve the block to be added, and if the block is not accurate, other nodes in the network will reject it.


Operations often waste effort on duplicate record keeping and third-party validations. Record-keeping systems can be vulnerable to fraud and cyberattacks. Limited transparency can slow data verification. And with the arrival of IoT, transaction volumes have exploded. All of this slows business, drains the bottom line — and means we need a better way. Enter blockchain.

To summarize, before anyone can modify the blockchain, they will expect to fix all of the blocks in the queue, reshape the proof-of-work for each block, and regulate the peer-to-peer arrangement.

This is impossible for anyone to do and that is why the blockchain remains the most secure and reliable technology today.


I hope you have been able to understand the technology with which Bitcoin operates and how it works.
