What is DeFi? Is It The Future Of Blockchain? | Crowdswap 2022 — CrowdSwap

DeFi stands for “decentralized finance,” a buzzword word for several cryptocurrencies and blockchain-based financial apps aimed at disrupting financial intermediaries.

DeFi is inspired by blockchain, the technology that underpins the digital currency bitcoin. Blockchain allows several organizations to keep a copy of transaction history, ensuring that it is not controlled by a single, central source. This is significant because centralized systems and human gatekeepers may slow down and complicate transactions while giving consumers less direct control over their funds. DeFi is unique in that it extends blockchain’s utility beyond simple asset transfer to more complicated financial applications.

How Was DeFi Born?

MakerDAO, a platform that started in 2015 and enabled users to utilize cryptocurrencies as collateral for loans, is frequently credited with launching DeFi. DeFi protocols, like regular cryptocurrencies, offer to cut out the middlemen. Until recently, the market has been propelled by this libertarian viewpoint and the desire of investors to make money.

DeFi extends on Bitcoin’s core principle — digital money — to provide a fully digital alternative to Wall Street, but without the accompanying fees. This can boost more open, free, and fair financial markets that anybody with an internet connection can access.

There’s a thriving crypto-economy out there, where you may lend, borrow, invest in long/short positions, earn interest, and more. DeFi has been utilized by crypto-savvy Argentinians to avoid catastrophic inflation. Companies have begun to broadcast their employees’ pay in real-time. Some people have even taken out and paid off multimillion-dollar loans without providing any personal information.

How Does DeFi Work?

Blockchain technology, which is also used in cryptocurrencies, is used in decentralized finance. A distributed and secure database or ledger is referred to as a blockchain. dApps are the applications that conduct transactions and run the blockchain.

Transactions are stored in blocks on the blockchain and subsequently validated by other users. If all of the verifiers agree on a transaction, the block is closed and encrypted, and a new block is generated containing information from the preceding block.

The information in each subsequent block “chains” the blocks together, giving the blockchain its name, and there is no method to edit a blockchain since information in prior blocks cannot be modified without impacting subsequent blocks. The safety aspect of a blockchain is provided by this notion, as well as other security mechanisms.

For many of these financial activities, one of the most appealing aspects of DeFi is that it removes the barrier to entry. You don’t have to have your money managed by the government or a business, and you don’t have to meet particular criteria to get certain financial goods.

You apply for a loan using standard banking procedures and may be denied depending on your credit. You have a bank account or a brokerage account with a business that manages your funds.

Certain financial transactions are carried out using DeFi’s smart contracts if certain requirements are satisfied. Borrowing, lending, and other transactions are all possible with smart contracts, and the conditions of the transaction are encoded in the code. While this makes transactions easier to use and more efficient, it also makes them more vulnerable to unfixable failures.

Differences Between DeFi and Traditional Finance

A public blockchain serves as the credibility source in decentralized finance, controlling all financial transactions. In conventional finance, on the other hand, public governance, which includes regulations and regulated financial organizations, serves as the source of trust, controlling all activities.

Decentralized finance is gaining popularity in part because it is more open and transparent than traditional money. Because there are no hurdles to entry, anybody with programming abilities may contribute to the development of financial services and tools on top of public blockchains.

The traditional financial system, on the other hand, has found it difficult to accept the new trend due to high entrance hurdles. The requirement of obtaining required licenses and authorization from authorities has stifled innovation in traditional financial systems.

Benefits Of DeFi


Blockchain has achieved true preservation thanks to the successful use of encryption and consensus techniques such as proof-of-work. As a result, the benefits and drawbacks of decentralized finance have permitted real immutability in finance.

It is virtually difficult to modify any record on the blockchain network, thanks to immutability. Immutability, in addition to the benefits of decentralization, provides a promising assurance of security. Surprisingly, the blockchain’s immutability features safeguard the integrity of DeFi systems when conducting financial transactions.

Full Control Over Finances

You keep control of your funds using DeFi platforms and also determine what happens to your funds when you deposit them into the site. A smart contract can qualify you for a loan or decide how to handle your finances instead of relying on human middlemen.

No one has the authority to exclude you from the DeFi protocol. The law that underpins the smart contract functions invisibly.


Decentralized finance relieves the burden of relying on institutions for monitoring, data storage, server space, and other services. By ensuring that individual transaction histories can be easily disseminated among all users, blockchain networks are effective in achieving all of these qualities.

The decentralization method is extremely beneficial to banking and finance democratization. DeFi may provide everyone with easy and efficient access to financial services. The bulk of DeFi solutions operates on Ethereum, according to DeFi pros and cons talks. Ethereum is the second-largest blockchain system, and it is extremely decentralized due to its permissionless nature.

It should also be easily available to everyone involved in the creation and usage of DeFi apps. The permissionless characteristics of blockchain in DeFi apps may potentially benefit from blockchain’s interoperability support. As a consequence, it can provide a variety of configurable alternatives for third-party integrations.

At the same time, it’s important to note that Ethereum’s permissionless blockchain capabilities aren’t unique. Ethereum is a trustworthy alternative for constructing DeFi apps since it is a favored network for developing smart contracts.

Increased Transparency

DeFi allows for more transparency and accountability. All activities are visible to the public since most DeFi protocols are built on the blockchain, which is a public ledger. Transactions can be viewed by anybody, but unlike traditional banks, these accounts are not linked to anyone personally.

Accounts instead are pseudo-anonymous, with just numerical addresses provided. Because most DeFi products are open source, users with programming skills can audit or improve the source code. Because of community participation, open-source programs are significantly more secure and of greater quality than proprietary software.

DeFi Comes With Risks

Many people feel that DeFi is the way of the future in finance and that investing in disruptive technology early on might pay off handsomely.

Newcomers, on the other hand, may find it difficult to distinguish between good and terrible initiatives. There has also been a lot of terrible.

Many DeFi apps, such as meme coin YAM, have crashed and burned as DeFi activity and popularity have surged through 2020, bringing the market value from $60 million to $0 in 35 minutes. Other DeFi businesses, such as Hotdog and Pizza, suffered the same fate, with many investors losing a significant amount of money.

Furthermore, DeFi problems are still a prevalent occurrence. Smart contracts are strong, but once the rules are baked into the protocol, they can’t be modified, which means faults are typically permanent, raising the risk.

How Can DeFi Evolve Further?

Payments made directly in the browser would be an interesting next step. Web authentication would let users access a protected private key in their web browser using touch or face ID, allowing crypto payments to be utilized in the real world. A website would just ask for payment in crypto and would not need to know the username of the person from whom it is requesting money.

Many companies are stepping in to fill the gap when someone wants to transmit money in cryptocurrency, but the recipient prefers conventional currency, such as pounds or dollars.
