Decentralized Finance (or DeFi) is a collection of financial apps built on top of blockchain networks.
Decentralized Finance refers to a movement aimed at creating an open-source, permissionless, and transparent financial service ecosystem that is accessible to anyone and operates without the use of a central authority. Users would own their assets outright and interact with the ecosystem using decentralized peer-to-peer (P2P) applications (dapps).
DeFi's main benefit is quick access to financial services, which is especially beneficial for people who are cut off from the current financial system. Another advantage of DeFi is its modular design; interoperable DeFi apps on public blockchains have the ability to develop entirely new financial markets, products, and services.
Traditional finance relies on banks as mediators and courts as arbitrators.
There are no intermediaries or arbitrators in DeFi applications. The coding outlines how any potential dispute will be resolved, and users retain complete control over their funds. This lowers the costs of offering and using these goods, making the financial system more frictionless.
Single points of failure are reduced because these new financial services are built on top of blockchains. Because the data is stored on the blockchain and is distributed across hundreds of nodes, censorship or the eventual shutdown of a service is difficult.
Deploying a DeFi application becomes significantly less complicated and safe since frameworks for DeFi apps may be established ahead of time.
Another key benefit of such an open environment is the ease with which those who would otherwise be unable to access financial services can do so. Because the old financial system relies on middlemen profiting, their services are frequently unavailable in low-income areas. DeFi, on the other hand, lowers expenses and gives low-income people access to a wider choice of financial services.
- Lending and Borrowing
Open lending protocols are one of the most popular types of DeFi applications. There are various benefits of open, decentralized borrowing and lending over the traditional credit system. Instant transaction settlement, the ability to collateralize digital assets, the lack of credit checks, and the prospect of future standardization are just a few of them.
These lending services demand less trust and are secured by cryptographic verification procedures because they are built on public blockchains. Borrowing and lending becomes more affordable, faster, and available to a larger spectrum of people thanks to blockchain-based loan systems that reduce counterparty risk.
- Banking Services
DeFi apps have a clear use case in financial banking services because they are, by definition, financial applications. These include stablecoin issuance, mortgages, and insurance, to name a few.
As the blockchain business evolves, stablecoins are becoming increasingly significant. They're a type of cryptoasset that's usually linked to a physical asset but can be transferred digitally. Given the volatility of cryptocurrency prices, decentralized stablecoins could be accepted for everyday use as digital cash that is not issued or administered by a central body.
Due to the multiple intermediaries that must be involved, the process of acquiring a mortgage is expensive and time-consuming. Smart contracts could save underwriting and legal expenditures significantly.
Insurance on the blockchain might do away with intermediaries and allow risk to be spread among a huge number of people. As a result, premiums could be reduced while service levels remain the same.
- Decentralized market places
This category of apps can be difficult to evaluate because it is the part of DeFi that allows for the most financial innovation.
Decentralized exchanges are perhaps among the most important DeFi uses (DEXes). These platforms allow users to trade digital assets without having to entrust their funds to a trusted third party (an exchange). Smart contracts allow transactions to be made directly between user wallets.
Because they require substantially less maintenance, decentralized exchanges can offer lower trading expenses than centralized exchanges.
Blockchain technology could be used to issue and own a variety of traditional financial instruments. These apps would be decentralized, with no need for custodians or single points of failure.
Issuers may be able to use security token issuance platforms to create tokenized securities on the blockchain with customized specifications.
Other efforts could lead to the formation of derivatives, synthetic assets, decentralized prediction markets, and other innovations.
The majority of Decentralized Finance's current and future uses entail the design and execution of smart contracts. A smart contract, unlike a traditional contract, employs computer code to establish the conditions of the connection between the parties to the contract.
Smart contracts have the unique capacity to enforce their terms through computer code since their terms are defined in computer code. This allows for the reliable execution and automation of a vast number of business processes that are now overseen by humans.
Smart contracts are simpler, faster, and less risky for both parties. Smart contracts, on the other hand, present new hazards. Because computer code is prone to errors and weaknesses, smart contracts' value and sensitive data are at danger.
- Poor performance
The apps built on top of blockchains are fundamentally slower than their centralized counterparts. DeFi application developers must account for these constraints and improve their offerings accordingly.
- High chances of user error
DeFi programs hand over control to the user from the middlemen. For some people, this is a disadvantage. When goods are implemented on top of immutable blockchains, designing products that reduce the risk of user error is a particularly challenging problem.
- Inadequate user experience
Currently, using DeFi applications takes additional effort on the part of the user. If DeFi applications are to become a core component of the global financial system, they must deliver a tangible benefit that encourages customers to shift away from the traditional system.
- Disarranged ecosystem
It can be challenging to choose the ideal application for a specific use case, and users must be able to make the best decisions. It's challenging not only to create the apps, but also to think about how they'll fit into the greater DeFi ecosystem.
Open banking is a banking system that grants secure access to financial data to third-party financial service providers via APIs. This allows banks and non-bank financial entities to network their accounts and data. In essence, it allows for new sorts of products and services to be offered within the old financial system.
While DeFi promises a brand new financial system that isn't reliant on existing infrastructure.
Open banking, for example, might make it possible to handle all traditional financial instruments in one application by securely combining data from multiple banks and institutions.
Decentralized Finance, on the other hand, may enable the administration of wholly new financial instruments as well as new ways of engaging with them.
The world of Decentralized Finance is aimed at developing a more independent financial services which is obviously different from the traditional financial bodies.
In as much as this will lead to a more open and secure means of running financial services, there are still a lot of improvements required on various DEfi platforms.
