How Does Decentralized Finance Work?


Share post:

Decentralized finance, also known as DeFi, is one of the blockchain industry’s fastest-growing sectors. On the one hand, cryptocurrencies offer alternatives to the use of government-backed money. Decentralized finance, on the other hand, is creating new financial tools that do not require centralized institutions. But how does decentralized finance actually operate? Let us find out right away!

So, let me explain how decentralized finance can function in our centralized economy and what you may expect from it. This article can help beginners learn more about the decentralized financial ecosystem.

The Working Model 

The DeFi blockchain ensures the process’s security by employing “keys.” When you utilize a set of encrypted keys with this technique, you will get a unique id that no one can access. This key pair typically consists of a public and a private key.

Using key pairs to encrypt information is called “asymmetric cryptography,” and it is used a lot in the blockchain space.

In essence, other peers can view or use your public key to locate you on the system. On the other hand, you can authorize transactions or any other form of action using your private key. You will need a private key to do some things on the DeFi blockchain network.

But some decentralized finance apps work differently and let you do things by using Know Your Customer (KYC) procedures.

Because cryptocurrencies are involved, your public key will most likely serve as your digital wallet. You can thus buy, sell, or even send cryptocurrency using your private key. This is why you must keep it secure.

So, in order to send a transaction, you must first authorize it with your private key. When you do this, the system will generate a block that represents the transaction and inform the system so that others can verify it. When other people confirm that your request is correct, your transaction request will be carried out and the block will be added to the ledger.

Also, each block has its own id and time frame, which makes it impossible to do anything bad.

You will be assigned pseudo-anonymous addresses in DeFi. So, in essence, no one will be able to see your name, but they will be able to view your address, which will comprise random numbers and letters.

Is Decentralized Finance Safe?

DeFi programs, on the other hand, are not entirely secure. In reality, no system can provide you with complete security. On the other hand, DeFi makes sure that it has a much more advanced security system than traditional ways of making money.

In actuality, hacking these applications is really difficult and time-consuming. Because the system is dispersed, cybercriminals must compromise every device that uses the application. This consumes a lot of resources and is ultimately not worth the effort.

There are concerns, however, if a DeFi application is released with an underlying fault or loophole. Many people are unsure whether using DeFi instead of CeFi is a good choice for this type of risk.

In any case, DeFi, like any other technology, is still in its early stages and has a long way to go. However, if we compare DeFi vs. CeFi, DeFi will undoubtedly prevail despite its faults.

The DeFi Ecosystem’s Key Elements and How They Work

Let’s go over the essential components of DeFi to see how they all fit together to form the ecosystem. In reality, each element has its own set of qualities. As a result, understanding how these functions work is required.

Essentially, there are five parts at the core.

  • Stablecoins
  • Intelligent Contracts
  • Exchanges and marketplaces
  • Platforms for Asset Management and Insurance
  • Open Ledger Standards

Open Ledger Standards

When developing a new type of DeFi application, the majority of decentralized finance companies adopt open ledger standards. This ensures that various applications can communicate with one another. Decentralized applications will not be compatible with one another unless they use common standards.

Another fantastic reality is that, without open-source standards, businesses cannot employ common standards. However, because the majority of the applications are built on Ethereum, it is obvious that these applications will have comparable standards.

Also, these standards make it possible for lending platforms to offer more options when it comes to digital assets.

Furthermore, the use of public blockchains has its own set of advantages, such as:

  • Permissionless network
  • Interoperability
  • Transparency
  • Immutability
  • Faster transactions

Smart Contracts

Smart contracts are an essential component of the DeFi ecosystem. In reality, smart contracts aid in the automation of the decentralized financing process. Smart contracts could automate everything from borrowing and lending money to making insurance claims.

Almost every DeFi application makes use of smart contracts to make its functionality more accessible. Furthermore, because smart contracts do not require a broker, there are no intermediate fees. Smart contracts are simpler, faster, and more secure than traditional contracts.

However, there are risks with DeFi when smart contracts are used to enable actions.


Decentralized finance is a revolutionary approach to our current monetary system that has the potential to make a huge impact. In reality, the ecosystem is vast and continuously increasing.

As a result, it’s only a matter of time before this technology is widely adopted throughout the world. You can now test these applications for yourself because you now understand how decentralized finance works as a result of this tutorial.
