Blockchain Explained— Cryptum Web 3 Main Concepts

Wed Jun 14 2023

Blockchain is the ultimate tool for decentralization and transparency, allowing people from all over the world to connect and engage with each other in a safe and secure way. It’s like a digital ledger that keeps track of every transaction made, and once something is recorded on the blockchain, it cannot be altered or deleted. This makes it an ideal platform for businesses and individuals to interact with each other without the need for intermediaries or third-party authorities. Plus, with blockchain’s advanced encryption methods, you can rest assured that your information and assets are protected from hackers and cybercriminals. So, join the blockchain revolution and start exploring the endless possibilities with Cyptum now!

Let’s get started:

  1. What’s Blockchain?

At its core, blockchain is a digital ledger that records transactions on a network of computers. Each transaction is verified and added to the ledger by a process called mining, which involves solving complex mathematical problems that require a lot of computing power. The miner who solves the problem first is rewarded with a cryptocurrency like Bitcoin.

The ledger is decentralized, meaning that there is no central authority controlling it. Instead, each computer, or node, on the network has a copy of the ledger. This ensures that the ledger is secure and cannot be altered by any one person or organization. The transactions on a blockchain are transparent and easily trackable, making it difficult for fraud or corruption to go unnoticed.

It is composed of a:

Node: Personal computer or, depending on the complexity of the network, a supercomputer

Standard Protocol: So that a network can communicate with each other

P2P: The peer-to-peer or P2P network is a network of nodes directly connected to the same network.

Decentralized System: All information is controlled by a network of computers that are equal to each other

Each of the blocks contains 3 fundamental things:

  • Information: Each block can contain different types of information such as information from a peer-to-peer transaction. It can contain the receiver, sender, date, amount
  • Hash: One of the most important for me, this is the identification number of the block, this is an unrepeatable number and it is also unique, each block is identified by a hash.
  • Connectivity: Each block has a hash and also the hash of the previous one, that is the way in which they communicate, so we could say that they are interconnected with the successor and predecessor.

2. Decentralization

In the context of technology and finance. At its core, decentralization refers to the distribution of power and decision-making across a network, rather than concentrating it in the hands of a single individual or organization.

One of the key reasons why decentralization matters is that it can help to promote greater equality and fairness. When power is concentrated in the hands of a few, it is often the case that some groups are marginalized or excluded from decision-making processes. This can lead to a range of social and economic inequalities, as well as the concentration of wealth and resources in the hands of a small elite.

Decentralization can help to address these issues by distributing power and decision-making more evenly across a network. This means that more people are able to participate in decision-making processes and that there is less risk of power being concentrated in the hands of a few. This can help to promote greater fairness and equality, and to create a more inclusive and democratic society.

Finally, decentralization helps to promote greater resilience and sustainability. When power and decision-making are concentrated in the hands of a few, there is a greater risk that the system will be vulnerable to shocks and disruptions. This can lead to instability and fragility and can make the system less sustainable over the long term.

3. Benefits of using Blockchain

One of the main benefits of blockchain technology is its security. Because the ledger is decentralized and each transaction is verified by multiple nodes on the network, it is virtually impossible to alter or delete a transaction. This makes blockchain ideal for industries like finance and healthcare, where security and privacy are critical.

Another benefit of blockchain is its transparency. Because each node on the network has a copy of the ledger, it is easy to track the history of a particular transaction. This makes it difficult for fraud or corruption to go unnoticed.

4. Decentralized Finance or DeFi

Decentralized finance, or DeFi, is a new movement within the financial industry that is built on blockchain technology. It aims to create a more open and accessible financial system that is not controlled by a central authority.

DeFi applications include things like peer-to-peer lending platforms, decentralized exchanges, and stablecoins. One of the benefits of DeFi is that it allows anyone with an internet connection to participate in the financial system, regardless of where they are in the world.

5. Tokens

Tokens are digital assets that are created and managed on a blockchain network. They are used to represent ownership of a particular asset, such as a physical object, a piece of intellectual property, or even a share in a company. Tokens have gained a lot of attention in recent years due to their potential to revolutionize the way we think about ownership and value.

One of the key benefits of tokens is that they allow for greater flexibility and accessibility when it comes to owning and transferring assets. Traditional forms of ownership, such as physical deeds or stock certificates, can be cumbersome and expensive to transfer. Tokens, on the other hand, can be easily transferred from one person to another, often with minimal transaction fees.

Tokens can also be used to represent a wide variety of assets, from real estate to artwork to intellectual property. This means that they have the potential to democratize ownership and to make it more accessible to a wider range of people.

6. Non-Fungible Tokens

Non-fungible tokens, or NFTs, are a new type of digital asset that are built on blockchain technology. Unlike cryptocurrencies like Bitcoin, which are fungible and can be exchanged for one another, NFTs are unique and cannot be exchanged for something else.

NFTs can be used to represent anything that is unique, like a piece of art, a collectible, or even a tweet

7. Cryptocurrencies

Cryptocurrencies are digital assets that use cryptography to secure and verify transactions and to control the creation of new units. They are decentralized, meaning that they are not controlled by any government or financial institution, and are instead managed by a network of computers around the world. Bitcoin was the first and most well-known cryptocurrency, but there are now thousands of different cryptocurrencies in circulation.

One of the key benefits of cryptocurrencies is that they provide a new way to transfer value without the need for intermediaries. Traditional financial institutions such as banks and payment processors can be slow and expensive and may be subject to government regulations and restrictions. Cryptocurrencies, on the other hand, allow for fast and inexpensive transactions, often with little to no fees.

Cryptocurrencies can also be used as a store of value, much like traditional currencies such as the US dollar or the Euro. However, unlike these fiat currencies, which are subject to inflation and devaluation, many cryptocurrencies have a limited supply, meaning that their value may be more stable over the long term.


In conclusion, blockchain technology opens up a new concept of the web called web 3.0, in which we do not send just information, we send value.

The value is given by the blockchain and its purposes.
