What is DeFi
Exploring the World of Decentralized Finance (DeFi) and its Implications for the Future of Finance
Decentralized finance—often called “DeFi”—refers to the shift from traditional, centralized financial systems to peer-to-peer finance enabled by decentralized technologies built on the Ethereum blockchain.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference.
Ethereum is used to build Decentralized Autonomous Organizations (DAOs). A DAO is an organization with no central authority or single administrator, where decisions are made transparently by the consensus of its members.
The code running on Ethereum is open source, meaning anyone can contribute to its development and audit it for security vulnerabilities. This makes Ethereum more secure than centralized platforms, which are vulnerable to attack by hackers.
From lending and borrowing platforms to stablecoins, protocols for earning interest on crypto, and beyond, DeFi applications are automating financial processes and instruments that have typically been managed by central authorities.
By deploying immutable smart contracts on Ethereum, DeFi developers can launch financial protocols and platforms that run exactly as programmed and that are available to anyone with an Internet connection.
The breakthrough of DeFi is that crypto assets can now be put to use in ways not possible with legacy fiat or “real world” assets: users can easily custody their own crypto funds, programmatically invest them according to custom rulesets, and earn a yield without having to entrust third parties with their private keys.
In this way, DeFi applications are enabling a new paradigm of open finance where financial services are permissionless, borderless, and composable.
What is a Stablecoin?
A stablecoin is a type of cryptocurrency that minimizes the price volatility often seen in traditional cryptocurrencies. In order to achieve stability, stablecoins are backed by reserve assets or pegged to another currency. This makes stablecoins ideal for use cases where traditional crypto would be impractical due to price volatility, such as payments or transferring value between exchanges.
The first and most popular stablecoin is Tether (USDT), which was launched in 2015 and is pegged to the US dollar. Since then, numerous other projects have launched their own versions of a dollar-pegged cryptocurrency including TrueUSD (TUSD), USD Coin (USDC), Paxos Standard Token (PAX) and Gemini Dollar (GUSD). There are also several non-dollar peg options available including EURS, GoldMint tokens (MNTP) and MakerDao's Dai token (DAI).
Why Use Stablecoins?
As mentioned earlier, one of the main advantages of using a stablecoin is that it eliminates price volatility often seen with other cryptocurrencies. This makes them perfect for use cases where quick settlements are needed or you don't want exposure to sudden swings in the market. For example, if you're an online merchant who accepts crypto payments but don't want recent changes in prices affecting how much profit you make on each sale, stablecoins can be used instead of more volatile options like Bitcoin or Ethereum. Similarly, if you're an investor looking to trade altcoins on a decentralized exchange but want to avoid dealing with wild fluctuations in prices, converting your holdings into astablecoin can help minimize risk while waiting for better entry points.. Other potential benefits include:
Easier international trade - since many fiat currencies fluctuate frequently relative to each other, utilizing a digital version of a more stabilized currency could lead to easier global commerce. (Forbes)
Increased adoption of blockchain technology - Although some people see blockchain and cryptocurrencies as synonymous, they’re actually quite different . By decoupling these technologies, it may allow for mass adoption of the latter without all the baggage associated with the former .
Easier micropayments - Due to transaction fees and volatility , small digital payments have been impractical up until now . If widespread adoption of fiat-backed cryptocurrencies takes place , this could pave the way for micropayments becoming commonplace .( VentureBeat )
How Do Stablecoins Work?
There are three primary ways that stablecoins can maintain a predetermined value :
Backed by reserves– The simplest model involves backing each coin or token with a real-world asset like a dollar in a pooled account somewhere ('fiat collateralized' ).
Pegged to another currency – In theory , any type of asset could be used to collateralize a stablecoin circulating in the system but in practice it has been most common for the securrencies to be either other fiats ('fiatpeg') or as a fehaven asset like gold (' commodity peg').
Algorithmic automatic stabilization mechanisms – Arising somewhat recently has been the development of algorithmically stabilize coins which attempt to use the power of the free markets rather than base the value of fiacol assets or crypto assets(" seigniorage shares" model ).
What is a Smart Contract
A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. This code is deployed onto the Ethereum blockchain, where it lives in immutable form — meaning it cannot be changed or deleted.
The defining feature of a smart contract is that it can automatically enforce the terms of an agreement between parties without the need for third-party oversight. For this reason, they are often known as “trustless agreements”. Because all participants can see that the contracts are executed as programmed, there is no need to rely on any one party to act in good faith — everything is transparent.
This automation also reduces transaction costs associated with traditional contractual arrangements, which must be regularly monitored and enforced by expensive lawyers and courts. Smart contracts provide a cheaper and more efficient way to manage these kinds of agreements.
In addition, because they live on the Ethereum blockchain, smart contracts benefit from its security features — most notably its decentralized nature. This makes them less susceptible to fraud or tampering than traditional paper contracts.
