Beginner Guide To Decentralized Finance (DeFi)

What is DeFi? Can I use it to earn interest on my Cryptocurrency holdings, is it risky and will it really change the future of Finance as we know it?

Today’s topic is Decentralized, Finance or DeFi for sure.

Bitcoin is a form of money that isn’t controlled by any central bank or government. It can be transferred to anyone from anyone around the world without the need of a bank or a financial institution. Bitcoin is Decentralized money. However, transferring money is only the first of many building blocks in the financial system.

Aside from sending money to one another, there are a variety of services we use today. For example, loans, savings plans, insurance and stock markets are all services that are built around money and together create our financial system. Today, our financial system and all of its services are completely centralized. Banks, stock markets, insurance companies and other financial institutions all have someone in charge, whether it be a company or a person that controls and offers these services.

This centralized financial system or CeFi, for short, has its risks mismanagement, fraud and corruption, to name a few. But what if we could Decentralized the financial system as a whole in the same way that Bitcoin Decentralized money? Well, that’s exactly what DeFi is all about. DeFi is a term given to financial services that have no central authority or someone in charge using Decentralized money like certain Crypto currencies that can be programmed for automated activities. We can build exchanges, lending services, insurance companies and other organizations that don’t have any owner and aren’t controlled by anyone confused.

We’ll break it down for you in order to create a Decentralized financial system. The first thing we need is an infrastructure for programming and running Decentralized services.

Luckily for us, Ethereum does just that. Ethereum is a do it yourself platform for writing Decentralized programs also known as Decentralized Apps or daps our What is a Theorem video explains Ethereum in great detail.

But for now we’ll just say that through the use of ether, we can write automated code also known as smart contracts that manage any financial service we’d like to create in a Decentralized manner. This means that we can determine the rules as to how a certain service will work, and once we deploy those rules on the Ethereum network, we no longer have control over them. They are immutable.

Once we have a system in place like Ethereum for creating Decentralized apps, we can start building our Decentralized financial system.

Now let’s take a look at some of the building blocks that comprise it. The first thing any financial system needs is, of course, money. You may be thinking why not use Bitcoin or ether, which is a theory EMCs currency. Well, as for Bitcoin, while it is indeed Decentralized, it has only very basic programmable functionality and is not compatible with the Ethereum platform either. On the other hand, is compatible and programmable. However, it’s also highly volatile.

 

Stablecoin : One of The Decentralized Finance (DeFi) Application

If we’re looking to build reliable financial services that people will want to use, we’ll need a more stable currency to operate within this system. This is where stable coins come in. Stable coins are Cryptocurrency that are pegged to the value of a real world asset, usually some major currency like the US dollar.

For the purpose of DeFi, we’ll want to use a stable coin that doesn’t use fiat money reserves for maintaining a peg, since this will require some sort of central authority.

This is where DAI comes into play. DAI is a Decentralized Cryptocurrency pegged against the value of the US dollar, meaning one DAI equals one US dollar.

Unlike other popular staple coins whose value is backed directly by US dollar reserves, DAI is backed by Crypto collaterals that can be viewed publicly on the Ethereum Blockchain DAI is over collateralized meaning if you lock up in a deposit one dollars worth of ether, you can borrow sixty six cents worth of DAI. As soon as you want your aether back, just pay back the DAI you borrowed and the ether will be released. If you don’t have any ether to lock up as collateral, you can just buy DAI on an exchange because DAI is over collateralized.

Even if ether’s price becomes extremely volatile, the value of the lot Eth are backing the DAI in circulation. Will most likely still remain at 100 percent or more, in essence, the DAI stable coin is actually also a smart contract that resides on the Ethereum platform. This makes DAI a truly trust and Decentralized stable coin, which cannot be shut down nor censored. Hence, it’s a perfect form of money for other DeFi services now that are Decentralized financial system has stable Decentralized money.

Decentralized Exchange

It’s time to create some additional services. The first use case that we’ll discuss is the Decentralized exchange, or DEX for short Dex’s operate according to a set of rules or smart contracts that allow users to buy, sell or trade Cryptocurrency Eth just like DAI. They also reside on the Eth Ethereum platform, which means they operate without a central authority. When you trade on a dex, there is no exchange operator, no sign ups, no identity verification and no withdrawal fees.

Instead, the smart contracts enforce the rules, execute trades and securely handle funds when necessary. Also, unlike a centralized exchange, there’s often no need to deposit funds into an exchange account before conducting a trade. This eliminates the major risk of exchange hacking, which exists for all centralized exchanges. But the range of Decentralized financial services doesn’t stop there. Let’s move on to Decentralized money markets services that connect borrowers with lenders.

 

Decentralized Lending

Compound is an Ethereum based borrowing and lending Dapp meaning you can Lend your Crypto out and earn interest on it. Alternatively, maybe you need some money to pay the rent or buy groceries, but the only funds you have are Cryptocurrency Eth. If that’s the case, you can deposit your Crypto as collateral and borrow against it.

The compound platform automatically connects the lenders with the borrowers and enforces the terms of the loans and distributes the interest. The process of earning interest on Cryptocurrency has become extremely popular lately, giving rise to Yield farming a term given to the effort of putting Crypto assets to work while seeking to generate the most returns possible. You can take a look at the description below this video for some of the more exciting DeFi projects that you can start using today. So now we have Decentralized stable coins, Decentralized exchanges and Decentralized money markets.

 

How about Decentralized insurance?

All of these new financial products definitely entail some risks, which we will cover shortly. So why not create a service that ensures my funds in case something goes wrong?

Well, how about a Decentralized platform that connects people who are willing to pay for insurance with people who are willing to insure them for a premium while everything happens autonomously without any insurance company or agent in the middle?

DeFi services work in conjunction with one another, making it possible to mix and match different services to create new and exciting opportunities. This kind of resembles how you can use different Lego blocks and get creative with whatever it is you want to build.

Hence the term money. Legos has been coined to refer to DeFi services. For example, you can build the following service from different money Legos. You start out by using a Decentralized exchange aggregator to find the exchange with the best rate for swapping ether for DAI. You then select the decks you want and conduct the trade. Then you Lend the DAI you receive to borrowers to earn interest. Finally, you can add insurance to this process to make sure you’re covered in case anything goes wrong.

That’s just one example. Out of the many opportunities DeFi offers.

 

By now, you can probably imagine what advantages DeFi presents transparency, interoperability, decentralization, free for all services and flexible user experience, to name just a few.

However, there are also some risks you should be aware of. The most important risk is that DeFi is still in its infancy and this means that things can go wrong. Smart contracts have had issues in the past where people didn’t define the rules for certain services correctly, and hackers found creative ways to exploit existing loopholes in order to steal money. If you decide to test out any of the existing DeFi services, make sure to do it with an amount of money you can afford to lose in case anything goes wrong.

 

Additionally, you should remember that a system is Decentralized only as its most central component. This means that some services may be only partially Decentralized while still keeping some centralized aspects that can act as an Achilles heel. It’s important to understand exactly how a product or service works before investing in it, so you can be aware of any issues that may come up.

 

To sum it up, it seems that the DeFi revolution has reached its early adopter stage and the coming years will tell if it manages to cross the chasm into mainstream adoption.

There’s no doubt that a Decentralized financial system can benefit a huge portion of the. That currently suffers from financial discrimination, high fees and inefficiencies in managing their funds. That’s it for today’s episode of Crypto Whiteboard Tuesday.

Hopefully by now you understand what DeFi is, a term given for a variety of Decentralized financial services that aim to replace our current centralized financial system
