Is blockchain the future? Explained in detail

If you’ve been reading up on the latest tech trends, you might have heard of ‘blockchain,’ which can be described as a decentralized and public ledger that records transactions between two parties. But what exactly is it? The system works by verifying transactions through cryptography, confirming every transfer of data from one computer to another. This essentially allows for information to have a digital signature that can’t be forged or tampered with; only the owner can modify their data. 

This technology has become more important in cryptocurrency Trading. For example, Margex has created a quality platform for trading the cryptocurrency derivatives market through its unique and user-friendly platform.

So it’s like a digital fingerprint, but with more complicated math involved?

Yes, that’s pretty much the gist of it. But unfortunately, when you have a publicly available ledger with millions of customers, you inevitably get some weird and complex problems that need to be solved. One of those problems includes ‘double spending,’ which essentially refers to someone using counterfeit money to pay for goods or services. 

Basics of Blockchain

A blockchain is a distributed database. When information is added to the database, it’s replicated across a whole network of computers. Any transaction history from that same wallet (or address) will be updated and stored on the blockchain each time that transaction occurs. This gives each block of data an individual identification number and timestamp so that anyone can see exactly when and where the data was created and by who.

Why does this work? 

Well, it’s a decentralized system, meaning that no single entity or company controls the data. Instead, the technology uses a ‘delegated blockchain,’ which means that anyone can connect to one of those blocks and verify each transaction without permission from another party.

With a decentralized system like this, there is no way to stop hackers from ‘hacking’ into our information; as long as they know your password or hold the private key to your account, they will be able to access all of your information at any time. However, a blockchain is completely secure and incorruptible; you alone cannot manipulate or delete the data on one because only you have the key.

Cross-Border Payments

Traditionally, the transfer of value has been both expensive and slow. One reason for this is that when different currencies are involved, the transfer procedure usually necessitates the cooperation of many institutions in multiple places before the intended receiver may get their funds. There are services available to assist speed up this procedure, but they are usually extremely pricey.

Blockchain technology has the potential to change all of this by allowing cross-border payments to be performed much more efficiently. Furthermore, in a blockchain system, multiple parties can interact with each other without the need for an intermediary or a third party, so it could be said that blockchain technology could make international payments cheaper than the current banking system.

Since blockchain technology does not work through banks and credit card companies, there is no need for them to take a cut from each transaction, as is the case with traditional payment systems.

Electronic Identities

The rise of digital technologies has given us access to unlimited amounts of information about ourselves and unlimited possibilities for conducting business and engaging in transactions that previously only existed in written form – many as recently as seventy years ago. 

It is even possible to store digital copies of documents in cloud storage systems and access them instantly from anywhere on the planet. 


Blockchain’s ability to provide a transparent ledger means reducing fraud by eliminating the possibility of falsifying data.

Every block on the blockchain contains the hash of all previous blocks and the hash of the previous block itself. So if someone changes a transaction to include false information, that information would be immediately apparent to everyone in the network.


In addition to its ability to eliminate fraud, blockchain provides additional security measures by having each transaction linked to a public key. This allows users to verify that they are making transactions with their accounts and not someone else’s. 

This is not only an additional layer of security but gives users the confidence that their identity is protected in ways other than just banking checks and passwords.

Transactions are also digitally secure and almost impossible to be hacked into. This level of security makes blockchain an appealing option for companies that have to deal with a huge amount of consumer information, like those in the financial industry.

Conclusion :

Blockchain technology is still in its early stages of development and is constantly evolving. However, with the capabilities offered by blockchain, it is no surprise that it is becoming increasingly popular in many industries. Even developments make smart contracts possible, which are agreements made between two parties in digital form and stored on the blockchain. Some banks are testing this new technology, but it is still very young. Nevertheless, it’s a technology worth keeping an eye on because it could be revolutionary.
