How Decentralised Finance Changing the Traditional Finance

Spread the love

DeFi (Decentralised Finance) has become a popular topic in the blockchain industry. In contrast to the decentralised money achieved through Bitcoin, DeFi seeks to decentralise the traditional financial system in general. The initiative’s primary objective is to make traditional financial services available to everyone by establishing a permissionless financial services ecosystem based on blockchain infrastructure. 


 But, what is DeFi? Decentralised Finance or ‘DeFi’ is an umbrella word that encompasses the idea of a financial system that operates without any middlemen, such as banks, insurance companies, or clearinghouses, and is solely powered by the power of smart contracts. DeFi apps aim to provide traditional finance services (also known as Centralised Finance, or simply CeFi) permissionless, global, and transparent.  

What is Decentralised Finance (DeFi)? 

One of the most remarkable aspects of Bitcoin when it originally appeared was its decentralised character. Previously, digital currencies required the support of a third party, such as a bank or government, to confirm transactions and guarantee payments. The same blockchain technology that underpins Bitcoin enables the decentralised banking sector to eliminate intermediaries.  


This has the potential to decrease expenses and bureaucracy while also expediting transactions. Overall, the blockchain-powered Decentralised Finance (DeFi) field is still in its early stages. Still, it presents a compelling value proposition in which consumers and organisations benefit from greater access to financial applications without the need for a trusted middleman.  


This initiative has the potential to help those who previously did not have access to such financial services. DeFi, on the other hand, guarantees a fully functional capital market. Thought in a small format at this moment. However, it is expanding.  

How does Decentralised Finance (DeFi) Work? 

Decentralised Finance, commonly known as, DeFi, is one of the blockchain industry’s fastest-growing categories. Even though the entire DeFi spectrum is modest, we expected tremendous growth in 2020. In January 2019, $278.75 million in value was locked in the DeFi economy; by January 2020, that figure had risen to $676.24 million. It has already reached $11.2B in October, a significant sum of money.  


However, many people aren’t sure what DeFi is or how it works. 


DeFi apps employ a distinct sort of distributed network to ensure that all transactions within the system are precise and limited to peers only. Furthermore, once a blockchain is verified and added to the ledger, no other peer may edit or erase it. 

The Working Methodology 

DeFi blockchain ensures the process’s security by employing “keys.” When you hire a set of encrypted keys with this technology, you will receive a unique identifier that no one else will have access to. This key pair typically consists of a public and private key. 


In actuality, this method of encrypting data with key pairs is known as “asymmetric cryptography,” and it is commonly used in the blockchain area. 


In essence, other peers may view or use your public key to locate you on the system. On the other hand, you may use your private key to approve transactions or any other form of activity.  


As a result, you will require a private key to do specific tasks on the DeFi blockchain network. 


However, some decentralised finance applications operate differently, allowing you to conduct operations using KYC procedures. 


Because cryptocurrencies are involved, your public key will most likely serve as your digital wallet. As a result, you may use your private key to purchase, trade, or even send cryptocurrency, and this is why you must maintain it secure. 


So, to send a transaction, you must first authorise 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 may verify it. After that, it will execute your transaction request and add the block to the ledger after others confirm that it is a valid request. 


Furthermore, each block is assigned a unique ID and time frame, which precludes any nefarious behaviour. 


You will be assigned pseudo-anonymous addresses in DeFi. So, while no one can see your name, they can see your address, which will include random numbers and letters. 

Key Characteristics of DeFi 

According to Defi Llama statistics, 2020 proved to be a historic year for DeFi. It increased from $700 million in Total Value Locked (TVL) in the System in December of 2019 to $20 billion by year-end 2020 and $230 billion now. Bulls think DeFi will ultimately replace the existing financial system with its old-fashioned and expensive layers of intermediaries. 


  • Decentralised 

As one of the most critical features of crypto-space, the codes are neither written nor managed by institutions’ staff. Instead, smart contracts are used to write the code, then deployed on the blockchain. Anybody may write these smart contracts, and no one has power over them, allowing for total decentralisation. 


  • Transparency  

Transparency in the Blockchain system enables users to develop a strong sense of trust in the network. Because of the blockchain’s openness, everyone can see and audit the code. You may be wondering if all transactions are visible if the user’s privacy is not jeopardised. While all transactions are visible, coding hides the user’s identity. 


  • Flexible 

This is one of the reasons why an increasing number of consumers are beginning to utilise DeFi services. If a user does not like the UI of a dApp, they may easily switch to another or even create their own. This enables users to select and modify the DeFi services that are most suited to their specific requirements. 


  • Interoperable 

A DeFi platform feature allows apps to be constructed by merging other DeFi products. As a result, many applications or goods can be combined to create something altogether new. 

Comparison Between Decentralised & Centralised Finance 


  • Permissionless Network 


  • Authorised persons can only carry out specific activities. 


  • DeFi is open-source, which means it promotes open collaboration. 


  • DeFi is immune to censorship since it is open-source. 


  • DeFi is less expensive. 


  • Permissioned Network 


  • There are no central authority figures. 


  • CeFi, on the other hand, isn’t open source.  


  • CeFi has the capability of being censored. 


  • CeFi is costly. 





What Are the Benefits of DeFi over Traditional Finance? 

With the rising popularity of new technologies such as Web 3.0, blockchain, smart contracts, and cryptocurrency, the notion of decentralised finance (DeFi) is gaining traction. DeFi alters the way we utilise financial instruments in profound ways.  


While the conventional financial system is based on a centralised platform that government institutions and many intermediaries control, DeFi is based on a protocol powered by blockchain and operates on a decentralised infrastructure (mainly Ethereum).  


As a result, programmers may create customizable, efficient, and secure financial systems that anybody with a computer and an internet connection can access. 


Without a doubt, DeFi is the new frontier because it empowers millions of people who do not have access to traditional financial systems. More than 1.700 million people are unbanked globally to manage their finances and transact with anyone, thanks to decentralisation, promoting equal opportunities and unprecedented economic growth. 


  1. Permissionless 

The term ‘decentralised’ is the first and most crucial aspect that determines the identity of decentralised finance. The concept’s definition primarily defines the benefits and drawbacks of decentralised finance. Decentralisation is a fundamental element of blockchain, and it aids in lowering reliance on companies. 


Furthermore, decentralised finance eliminates relying on institutions for monitoring, data storage, server space, and other difficulties. These objectives are met by blockchain networks, which ensure that specific transaction histories may be easily transmitted among all users. 


The decentralisation strategy is highly beneficial to democratise banking and finance, and DeFi may provide everyone with easy and efficient access to financial services. Discussions of the benefits and drawbacks of DeFi would also reveal that the vast majority of DeFi solutions operate on Ethereum. Ethereum is the second-largest blockchain system, and its permissionless nature makes it highly decentralised. 


It should also be readily available to everyone involved in creating and using DeFi apps. The permissionless characteristics of blockchain in DeFi applications may potentially benefit from blockchain interoperability. As a result, it may provide versatile choices for many sorts of third-party connections. 


At the same time, it is essential to note that the permissionless blockchain capabilities are not exclusive to Ethereum. Because Ethereum is a popular network for constructing smart contracts, it is a safe bet for designing DeFi apps. 


  1. Immutability 

The practical application of encryption in conjunction with consensus mechanisms such as proof-of-work has benefited blockchain in achieving absolute immutability. As a result of the benefits and drawbacks of decentralised finance, actual benefits of immutability in finance have been realised. 


Because of the immutability of the blockchain network, it is practically impossible to edit any record. In addition to the benefits of decentralisation, immutability gives an acceptable level of security assurance. Surprisingly, the immutability capabilities of blockchain ensure the integrity of DeFi systems when carrying out financial transactions. 



  1. Transparency 

While immutability is required for the DeFi landscape to give security assurance, transparency is also a significant addition among DeFi professionals. Decentralisation, of course, implies more transparency, and the distributed ledger contains data on all blockchain network activity. 


The blockchain’s cryptographic principles also ensure that information is only documented once its legitimacy has been verified. The benefits and drawbacks of DeFi demonstrate how customers may benefit from DeFi applications‘ openness. 


  1. Applications for Savings 

The benefits and drawbacks of decentralised finance also highlight the rising popularity of DeFi savings products. People might also use DeFi to manage their funds more effectively. Users might begin receiving interest on assets locked in lending protocols such as Compound. As a result, several DeFi savings programs have appeared in recent years. 


Such programs allow users to tap into numerous loan protocols to increase their earning potential. At this point, it would be appropriate to mention ‘yield farming.’  


Yield farming has been a positive component of the DeFi ecosystem, particularly in demonstrating how users may shift their idle crypto assets across several loan protocols for higher yields. 


  1. Tokenization 

 Any explanation of the benefits and drawbacks of DeFi would be incomplete if the benefits of tokenization were not included. Tokenization is one of the significant concepts that later appeared in the blockchain sector, and Ethereum provides extensive smart contract capabilities, paving the way for the issuance of cryptocurrency tokens. 


Crypto tokens functioned primarily as digital assets stored on a blockchain, with varying characteristics and applications. Utility tokens native to a specific dApp, real estate tokens, and security tokens are some basic forms of tokens. 


Tokens can assist you with a variety of functions. Real estate tokens might assist you in achieving fractional ownership of tangible assets. On the other hand, security tokens might be used successfully as digital shares in specific applications. Most importantly, tokenization might increase exposure to other assets, both tangible and digital. 



What Are The Problems That DeFi Initiatives Face? 

Many of the current notable talks on decentralised finance centre on the benefits of DeFi. However, to correctly estimate DeFi’s potential, it is necessary to have an impartial sense of its merits and negatives. In truth, the bulk of difficulties and hazards connected with a DeFi project is essentially associated with the technology they are linked to.  


The challenges with blockchain are typically to blame for increasing the disadvantages of DeFi. Here are some of the significant drawbacks you may face if you use DeFi: 


  • Scalability 

DeFi programs are undeniably effective in encouraging financial inclusion for a broader population. However, DeFi efforts have substantial issues in the scalability of the host blockchain from a variety of perspectives, and DeFi transactions need extremely long confirmation times. 


At the same time, during a moment of congestion, transactions over DeFi protocols may become prohibitively costly. With Ethereum at total capacity, for example, it may demonstrate capabilities of processing nearly 13 transactions per second. On the contrary, DeFi’s centralized equivalents could support thousands of transactions throughout the relevant period. 


  • Uncertainty 

Concerns about unpredictability also impact the benefits and drawbacks of decentralized finance. If the blockchain that hosts a DeFi project is unstable, the project may inherit the host blockchain’s instability. The Ethereum blockchain is currently undergoing several improvements. For example, errors made during the shift from PoW consensus to the new Eth 2.0 PoS method might pose dangers. 

Applications of  DeFi 

DeFi has a wide range of applications nowadays. Decentralized finance (DeFi)  may be used in a variety of sectors to provide simple, rapid, and convenient procedures: 


  • Analytics & Data 

Decentralized finance protocols provide quick data analysis, discovery, and financial and risk management decision-making. It is feasible because it is based on blockchain technology, offering transparent access to all transaction data and network activities. As the number of new DeFi dApp apps has increased, several tools and dashboards have been developed to help customers measure overall value protection and evaluate platform risks. 


  • Insurance 

Decentralized finance is a notion that is currently in its early stages. A few hazards associated with smart contract issues must be addressed before using them in sensitive industries such as insurance. However, by deploying DeFi, the insurance business may reap enormous benefits in increased transparency, authenticity, and security. Numerous new options have been offered to aid consumers in claiming insurance and preserving their possessions. 


  • Payment Process and Monetary Banking Services 

The major use of decentralized finance and blockchain technology is monetary use cases such as payments and banking. DeFi payments will build payments and banking system that is more: Because blockchain allows users to safely and directly swap cryptocurrencies without intermediaries, DeFi payments will produce a payment and banking system that is more: 

  • open  
  • easy-to-use  
  • accessible 


  • Markets and Exchanges 

Decentralized exchanges feature peer-to-peer transactions on the blockchain between two parties, with no intermediaries or mediators involved. As a result, they differ greatly from centralized exchanges. DeFi protocols enable consumers to exchange items and services internationally and directly through multiple online marketplaces (P2P). 


The following are some advantages of using DeFi in exchanges and marketplaces: 


  • no sign-ups. 
  • no identification verification 
  • no withdrawal costs. 

To Conclude, 

Crypto is a digital product with the potential to change every business. We can anticipate that most financial companies will include DeFi in their systems shortly. Collateral is being used as a security mechanism in DeFi applications for lending and borrowing operations. DeFi can be a substantial source of change in the insurance business. 


Furthermore, a considerable change toward “decentralised governance” and “decentralised decision making” is projected soon, as more and more individuals move toward decentralized means of doing business and transactions.
