Encrypted Blockchain Technology (2020)

In recent years you will have come across the term “blockchain”, which you hear more and more often. This is all too understandable when you consider that many compare the importance of blockchains to that of the Internet in the 1990s. But what is a blockchain? How it works But above all, how can you set up to benefit from this potentially enormous growth potential. Read on and find out!

A blockchain is a shared database, list, or directory of financial transactions that is stored on different computers in different locations. The database grows continuously as new transactions or “blocks” are added. These form an endless series of data entries in which all processes can be viewed and verified. Since there is no intermediary, it is difficult to forge the exact entries of millions of blockchain entries.

What is Bitcoin technology and how has it changed the financial world?

There are three main techniques that come together when building a blockchain. This includes encryption of the private code, a network with a common directory and an incentive to secure the network transactions and records. These come together to make blockchain technology a decentralized, transparent and non-manipulable system. If you are interested in starting online crypto trading, you should Bitcoin era look at.


Most traditional payment methods are centralized. For example, your bank keeps your money, and to pay someone else, you also need to contact your bank. This has several disadvantages:

  1. All data is kept in one place, making it an easy target for hackers.
  2. If the central facility is closed or goes bankrupt, no one has access to the data in its possession.

In a decentralized system like that created by blockchain technology, data cannot be stored by a single facility. Everyone in the Bitcoin network has this data and can view the transaction directory, which cannot be changed by other users. This durability is another pillar of this technology.


As soon as something is entered into the blockchain, there is nothing to shake about it. It is completely impossible to manipulate blocks. This is because the basic technology uses number hashes. In terms of payment, this means that business is seen as a contribution and goes through a hash algorithm that must be of a certain length and size. This means that each hash defines a whole series of calculations or data series.


The most motivating thing about this technology is the fact that it enables a high degree of clarity and discretion at the same time. The identity of the user is protected and can only be read at the open address.

The user ID is secure. You can still see all the business done at the public address. There is not so much clarity in the current monetary system, which is why this technique will change the world of finance.

How does a blockchain work?

Let’s say Muhammad wants to transfer money to Jamil. With blockchain technology, this online transfer is represented as a block. This block is then distributed across the entire blockchain network, a special type of P2P network in which the work is shared between the participants instead of being taken over by a central server.

Muhammad testified of his ownership of the money and then handed it over to Jamil. The technology makes a mediator superfluous and enables complete transparency and anonymity.

Explain blockchain using real-world examples

One of the first uses of this technology was with the cryptocurrencies Bitcoin and Ethereum. This is because this technology enables digital information to be disseminated and not copied at the same time, which means that each piece of data can only have one owner, which is necessary when dealing with payments. So it is a digital fingerprint.

By the way, did you know that you can also trade contracts for difference (CFDs) in Bitcoin, Ethereum and others on Admiral Markets? Trading CFDs on cryptocurrencies allows you to speculate on the direction of a cryptocurrency exchange rate without owning it.
