DEFI or Decentralized Finance are an alternative to traditional finance. Traditional financial services are all products related to the means of payment or money management offered by a bank, a financial institution, insurance companies or investment companies among others.

These traditional finances carry with them a series of obstacles, limitations and regulations that make them unattainable for some and unattractive for others. Such as high commissions or control by banks and regulators.

Thanks to Blockchain and cryptocurrencies, DEFIs have arrived to update, improve and globalize this type of already obsolete finances, making them available to everyone regardless of where they are meaning if someone has access to the Internet, they can use them.

The Traditional Financial System

The current financial system is the center of most economies. All the functionalities of this system are controlled by centralized authorities like governments, banks, and other financial institutions.

People put their money in banks and other financial institutions for savings and often put in fixed and recurring deposits to earn profits. As the system is centralized, the risk is also at the center.

The first problem is that when someone deposits money to banks or other organizations, he has no control over his assets. He has little to no knowledge where his money gets invested and how it is handled by these corporations. So, this system lacks transparency.

These centralized institutions invest that stacked money in share markets as well as give loans at high-interest rates earning huge profit. But only a fraction of these is returned to depositors. When it comes to investing, a financial advisor advises investors in exchange for a cut in returns. But this investment is also risky as the advisor can make mistakes in assessing markets.

One of the most unfair and largely unaddressed issues of the existing financial system is the unequal to financial services. According to some estimates, over 1.7 billion people worldwide do not have access to bank accounts or financial institutions of any type.

To address these drawbacks of the financial systems, the world now has Decentralized Finance (DeFi).

What are decentralized Finance (DEFI)?

DEFI decentralized finances

DEFIs are a new financial ecosystem, decentralized, global, transparent, resistant to censorship, without intermediaries and easily accessible, where each user has full control of their assets.

Decentralized Finance (DeFi) aims to provide a global, open alternative to every financial service that people use today. This only requires an internet connection and a smartphone.

The tools to carry out these decentralized finances are digital assets, decentralized applications (dApps), Smart Contracts, protocols and decentralized exchanges (DEX).

And the alternatives that this new financial ecosystem offers are decentralized loans, decentralized oracles or non-custody token exchanges, among others.

Ethereum leads the decentralized finances from the beginning with projects based on Ethereum, such as MakerDAO or Augur, but little by little other large platforms in the sector such as EOS, Algorand or Tezos, among others, are preparing to claim their share of the pie.

What do DeFi promise?

Global Access To Financial Services

Anyone can create DeFi apps, and anyone can use them. DeFi applications provide global access to financial services, although local restriction may apply. To access the DeFi platforms like Maker or Compound Finance, users only require an internet connection and a smartphone regardless of their location or country.

Complete Control Over Assets

DeFi offers users complete control over their assets as anyone can store, trade, and invest their assets in blockchain securely, and no intermediaries are handling these assets except smart contracts. So users have complete control over their assets.

Privacy, Security, and Transparency

With DeFi, users have custody of their wealth and can transact securely without validation from a central party. As all the activities are recorded on the blockchain, all transactions are publicly available. So this offers better transparency than a centralized system, where records can be altered easily.

Payments and Settlements

There is a vast and expensive network of intermediaries that are involved in cross-border payments. But they take days to settle these transactions and charge a heavy fee for their service. DeFi has the potential to completely remove these costly intermediaries, allowing remittance services to be much more affordable and efficient for the global population.

DeFi promises a lot more than this. Censorship-resistant transactions and high returns are also achievable through DeFi. DeFi apps also provide flexible user experience and interoperability with other products.

DEFI loans

Among the financial alternatives offered by DEFIs, we can highlight decentralized loans, which have much higher returns than those offered by traditional market funds, even reaching 18%, against 2-3% of the traditional market.

Thanks to decentralized finances you can request a loan without the need for intermediaries.

What do these projects contribute to DEFIs?

Despite the problems of scalability in its network, if there is a project associated from the beginning to the DEFIs that is Ethereum, for example, its products with the stablecoin DAI, have been acclaimed as immensely interchangeable financial products.

“I am very excited about the potential that DeFi offers in principle. The idea that anyone, anywhere in the world, can have access to a system that allows them to pay each other and choose their own financial exposure, is something really powerful.”, said Vitalik Buterin at the Ethereal conference held in Tel Aviv.

But, although Ethereum has been there from the beginning, it cannot be trusted as competitors begin to step on their heels.


EOS, second layer of Ethereum

EOS is a high performance blockchain platform, one of its missions is to support decentralized applications that provide all the benefits offered by blockchain technology.

“When we talk about DeFi, ETH failed. Ask bitfinex, bancor or any team that wants to implement a simple order book in ETH. The EOSIO design is based on the initial lessons of decentralization of the bithares financial platform. Speed, low latency, ordered indexing, floating point and C++, are only available in EOSIO. EOSIO has RAM, leasing of network bandwidth resources, banking, token name bidding and various anchor token designs in the market. The decentralized future is in EOSIO.”, tweeted Daniel Larimer on his Twitter account.



Algorand seeks to provide the same services that Ethereum offers, only with better performance and ending the common security, scalability and decentralization problems that other blockchain have.

“Our participation test protocol is the first of its kind to support the scale, open participation and purpose of transactions for billions of users. All backed by a sustainable business and a recognized team of experts.”, they state on their website.

As for the DEFI, as announced by its Founder Silvio Micali, Algorand is working on the generation of new fungible tokens and the execution of multipartite atomic transfers (AMPT).



Like its competitors, Tezos works to be a tool for the development of smart contracts and decentralized applications (dApps).

“The Tezos Foundation is pleased to announce that 14 new grants have been issued for projects submitted in response to its most recent request for proposals (RFP). The Foundation considered proposals targeting the following categories as part of this RFP: Applications created using contracts Tezos smart (with special interest in decentralized finance or “DeFi” applications) “, they say on the tezos foundation blog.

Of these projects, the focus on DEFIs is Protofire, a development team focused on the smart contracts.


DeFi has the potential to change the current financial landscape positively. But it is still a tiny market and has a long way to go. With new projects and protocols entering the market, the world can expect a true decentralized financial system in the upcoming years.
