Definition of DeFi (Decentralized Finance)

Almost every beginner would wonder about ‘what is DeFi’, and it is reasonable. DeFi is the abbreviation for Decentralized Finance, which implies an assortment of financial applications that leverage blockchain networks and technologies. Decentralized Finance DeFi has introduced a formidable change in viewing financial transactions beyond the existing assumptions of the prevailing, closed financial market.

The potential of DeFi is tailored for shifting the attention towards a financial economy with better transparency. In the supposedly new, open financial economy, financial protocols would rely on three dominant elements: interoperability, programmability, and ease of composing. Decentralized Finance is the architect and leader of the Open Finance movement.

With the Open Finance Movement, users can find alternatives for financial services such as savings, insurance, loans, trading, and many other significant financial activities. The prospects with DeFi applications are expected to surpass the conventional, closed financial applications in terms of scope and reach. First of all, DeFi presents better chances for accessibility to every individual having a two-core dependency.

Two-core dependency implies internet connectivity and devices for accessing a service, such as a computer, smartphone, or tablet. The most crucial factor in an introduction to DeFi would refer to the possibility of leveraging Ethereum for the integration of cryptocurrency, financial systems, and blockchain technology efficiently. Therefore, it is easier to understand that DeFi capitalizes on the existing financial market to ensure better transparency and feasibility of editing for different protocols.

Purpose of DeFi (Decentralized Finance)

The next crucial concern for any individual after learning about what is Decentralized Finance is the purpose it serves. It is reasonable to wonder about why DeFi came into existence, and this question becomes quite inevitable in times when decentralized finance is being termed as an unstoppable phenomenon. Therefore, a closer reflection on the origins of DeFi can shed light on what is DeFi and why we need it.

The centralization factor in the traditional marketplace is an evident detail with the influence of governments, also centralized in terms of structure. Therefore, the currency system is also supposed to function through centralized entities such as banks. The centralization factor implies the management and regulation of centralized entities, with absolute control vested in the entities.

Furthermore, a centralized approach also implies higher risk due to the single point of failure. Many questions about the functionalities of centralized entities also create the need to focus on alternatives. For example, the timing of decisions by authorities for printing more currencies and the impact of factors such as financial need or the need for continuity on such decisions are some of the questions that create doubts about the long-term potential of centralized finance systems.

How did Decentralized Finance Come Into Existence – Origin of DeFi

The understanding of the origins of DeFi takes you beyond the simple answers to what is DeFi. Let us take the example of dollars to understand the pitfalls in centralized entities. The continuously declining value of dollars over the last 50 years shows that it had comparatively higher purchasing power than that in 2020. The inflation in currency value requires you to have more currency for purchasing the same product that you could have purchased in the past.

The example of Venezuelan government’s bad monetary policies and their impact on an all-time high inflation rate draws attention towards the setbacks of centralized entities. The government further exacerbated the situation through decision to print more currency in event of a drop in oil price. As a result, the 1,000,000% inflation rate created a drastic imbalance in Venezuela’s economy. Banks are also one of the critical factors that have a role in fostering the idea of Decentralized Finance.

Almost all banks provide interest on the savings of a customer in the form of recurring or fixed amounts. However, banks utilize the money of customers for investment in different markets through loans to businesses at higher interest rates. As a result, banks gain larger profits from the money of customers while returning a trivial fraction of the profit to the customer.

Annual interest rates worldwide are poised at 2-3%, thereby indicating that customers don’t get the benefits they want by depositing their money in banks. Therefore, customers should find ways to diversify their investments in the share market, schemes, mutual funds, and many other financial instruments. At this point, the importance of what is DeFi becomes evident as banks don’t allow control for customers to diversify their investments.

The limited requirement of KYC or credit checks for accessing financial services with open ledger protocols also present credible advantages.

It is important to understand the risks in DeFi to discover its potential from a neutral perspective. Here’s a guide to Risks in DeFi and how to manage them.

  • Stablecoins

Stablecoins are formidable components for understanding DeFi ecosystem, as they are compared in terms of value of real-world currency assets. Generally, all stablecoins in the existing DeFi ecosystem are pinned against the US dollar. The primary objective is to ensure better performance, trust, and stability.

The design of stablecoins for maintaining stability compared to cryptocurrencies is also a striking highlight for the DeFi ecosystem. Stablecoins are classified into three different categories, such as fiat-collateralized, non-collateralized, and crypto-collateralized stablecoins with distinct traits and functionalities. Fiat-collateralized stablecoins are pinned against a real currency like US dollar or Euro, thereby providing better assurance of stability.

The same ratio comparison with fiat currency ensures better stability and non-volatility with stablecoins. The commonly accepted fiat-collateralized stablecoins refer to Gemini Dollars, Tether, USDC, and many others. Fiat-collateralized coins also come with certain risks, especially with the requirement of a centralized authority.

Also, you need proper regulations for maintenance and adoption of stablecoins among the general public. Crypto-collateralized stablecoins are similar to fiat-collateralized stablecoins with cryptocurrencies replacing fiat currency. The primary factors that drive stability of crypto-collateralized stablecoins include utility incentives and trustless insurance. One of the prominent examples of crypto-collateralized stablecoin refers to DAI.

Crypto-collateralized stablecoins depend on collateralization, only when the stablecoin slips to debt. The volatility issues with crypto-collateralized stablecoins find a reliable answer by enabling the protocol with lender capabilities. The last type of stablecoins is non-collateralized stablecoins. The striking highlight of non-collateralized stablecoins is the underlying algorithm driving the development of additional tokens. It works in event of the need for ensuring the reduction of token value and maintaining stability.
