Decentralized finance (DeFi) is when applications are deployed via blockchain networks to make financial assets available to the avergae person without the need for middlemen such as financial brokers. In contrast to establishing an account with a bank or brokerage business, you do not need to submit personal details to get started with decentralized finance. Instead, DeFi is often used to refer to a system that uses stringent software to link buyers, sellers, lenders, and borrowers with peers or an intermediary. This contrasts with a company facilitating transactions or a fintech-focused app development firm.
The development of decentralized financial systems is still in its early stages. According to DefiLlama, the total TVL of the DeFi industry is currently over $55 billion. Although the overall amount of DeFi may seem large initially, it is vital to remember that the bulk of its coins lacks the liquidity or volume to be traded on cryptocurrency exchanges. Furthermore, there are infrastructural issues, such as hackers and other weaknesses in DeFi systems. Scams abound in the fast-expanding world of distributed ledger technologies. DeFi's transaction span is without bounds for this kind of regulation.
Smart Contracts
The DeFi legislation emphasizes digitally signed smart contracts. Smart contracts are self-executing programs that activate once predetermined conditions have been met, and these contracts power many applications in the DeFi space. For example, decentralized exchanges (DEXs) use a combination of smart contracts and automated market makers (AMMs) to enable users to swap tokens almost instantly. Instead of relying on an order book with orders from other traders, smart contracts enable swapping tokens from a user's wallet and the liquidity pools that store the tokens in the DEX.
Minting Mechanism
Another example is the minting mechanism seen with NFTs. Once the smart contract receives a certain amount of tokens, it deposits the NFT into the sender's wallet. For example, if it costs 0.5 ETH to mint an NFT and there's a maximum minting limit of 3, the smart contract will deposit 3 NFTs to the wallet that sends 1.5 ETH, 2 NFTs if 1 ETH is sent and 1 NFT is 0.5 ETH sent from that wallet. Smart contracts remove the need for a middleman to manage the interactions between users and protocols within the blockchain space.
Stablecoins are a popular DeFi staple
The industry of stablecoins is another area where decentralized finance is rapidly expanding. Stablecoins provide a safer and less volatile alternative for investors who want to earn money via DeFi. Tether (USDT is currently the most popular stablecoin, followed by USD Coin (USDC). These cryptocurrencies are pegged to the US dollar, with their values staying within the $1 range with very slight fluctuations. This is in contrast to regular cryptocurrencies whose values can change drastically over time. The relative stability of stablecoins makes them an attractive investment vehicle, especially during bear markets, with investors able to stake these coins for a fixed percentage return.
Conclusion
Because of advancements in blockchain security, we will continue to see new developments, protocols, and advancements over the years. Furthermore, DeFi increases its market position by expanding the size of its blockchain community. Considering the continued growth of DeFi, the next few years will prove more significant for the emerging sector.
