An Overview of Decentralized Finance

The Road to DeFi

Global wealth is increasing, but so is the gap between the rich and the poor. According to the 2018 Global Wealth Report published by the Credit Suisse Research Institute, global wealth currently stands at $317 trillion dollars. However, according to Credit Suisse’s 2018 Global Wealth Databook, income inequality is a problem, with the world’s richest 1 percent owning 45 percent of global wealth.

According to some experts, one of the leading causes of global wealth inequality is lack of access to formal financial services. Around 1.7 billion adults worldwide still do not have a bank account and lack access to formal savings and credit services. The good news though is that we’ve made strides in increasing access to financial services. This is most notable in developing economies that saw an increase in financial inclusion from 62 percent to 69 percent.

In the Philippines, for example, fintech startup Ayannah offers digital remittances, payments and business services through its platforms Sendah, Sendah Direct, and Sendah Remit. Ayannah offers peer-to-peer transactions through online and mobile platforms, enabling more Filipinos with a mobile device and internet access to access previously unavailable digital financial services. Similar digital financial services also exist in other developing economies. In Africa, mobile payments for bills and everyday services are taking off, even though many people there lack bank accounts.

According to ChainRift Research, 2 percent of Kenya’s households have been lifted out of poverty since the proliferation of M-Pesa. M-Pesa is a fintech initiative that first sought to digitize parts of microfinancing services, including distribution and payments. Over time, it expanded into a remittance service that allowed more people to transact faster and at more affordable rates.

In India, fintech platforms have helped increase financial inclusion as well. Fintech platforms like the ones offered by Mobikwik, an Indian company providing digital payments and wallet services, have provided financial services to more unbanked and underserved households.

On the surface, full financial inclusion still appears hard to attain. However, with the technological innovations we are witnessing, the future might still be positive for those at the bottom of the pyramid. We can harness these innovations to narrow the overwhelming gap in our global financial system.

People coming from low-income communities find it very difficult to access formal banking services. These services include savings accounts, investment services, loans, and financial literacy programs. According to a study from the Wharton School, this is one of the many traps that keep the underbanked and unbanked locked in a vicious cycle of poverty. The proposition is simple: improve financial literacy and improve access to basic banking services. People must be able to control their financial fates.

Blockchain, Decentralized Finance & Financial Inclusion

Blockchain and cryptocurrencies have been heralded as a potential solution to increase financial inclusion. After all, cryptocurrencies are secure, can freely cross borders, and can be held by anyone with basic internet access. Blockchains supporting these cryptocurrencies can be built so that no central authority or government can control it or use their power to deny access to certain people. The question is, can crypto realistically solve the problems of unbanked and underbanked people?

Proponents believe that cryptocurrencies enable decentralized finance, or DeFi. DeFi is an alternative to the traditional financial system controlled and regulated by governments, financial institutions, and regulators.

A prevalent attitude with current traditional financial institutions is that it is not cost-efficient to provide services to low-income citizens. For example, many banks don’t like to maintain accounts for low-income individuals since they can’t maintain sizable deposits. This is one reason why many banks require minimum account balances, which in turn, discourage many lower income individuals from opening bank accounts.

Another issue is that financial institutions often require government-issued identification before opening accounts. Many poor people, refugees, and other disenfranchised people don’t have these documents and have no way of obtaining them. This becomes another barrier to financial inclusion.

Until now, there was no real alternative to this centralized financial system. Financial inclusion was only a dream for most of the world. This status quo is one which the blockchain seeks to disrupt.

Blockchain overcomes these issues by making it easier for everyone to access secure, reliable, borderless, affordable, and fast digital financial services previously unavailable to them.

Blockchain’s primary aim is to enable a system that does not need any centralized party to govern financial transactions. This means lower barriers to entry, a system not governed by any particular individual, entity, or government authority, and a network that maintains safety, security and reliability of transactions.

What makes Decentralized Finance (DeFi) unique?

DeFi services can be accessed by everybody. Anyone with internet access and a connected device can join the digital financial system. There is no authority to prevent and filter those who wish to access the network. Similarly, anyone can deploy financial service applications on blockchains without explicit permission from regulators. The creators of Bitcoin didn’t ask for permission from anyone.

DeFi is decentralized. DeFi services work without third parties having to approve transactions. Blockchain also enables users to engage in Peer-to-Peer (P2P) transactions. This creates a cheap and fast 24/7 transaction network.

DeFi systems are secure – The blockchain offers a decentralized ledger that records every transaction made in the network, with records are spread across all its members. Also, its decentralized nature allows the application to have no single point of failure, differentiating it from the traditional financial system. These properties  make way for a robust, trustless, immutable, and transparent system that does not need another party to validate all transactions made.

DeFi services are resistant to outside control. Blockchains can be built so that individuals and entities cannot control it. Public-private key cryptography can ensure that individuals can securely transact with each other without worrying about being monitored, restricted or having their access revoked. User funds can be secured in crypto wallets without relying on banks and government institutions. This way, funds cannot be confiscated or seized. This is especially important in countries characterized by oppression and censorship.

DeFi services are built for trust. Smart contracts deployed on blockchains can make financial applications more transparent, immutable, and streamlined. Participants are reassured that the code behind smart contracts are open to the public for tested. Most DeFi services are open source and available for developers to build on and improve.

DeFi Services Available Today

In addition to creating innovative new financial services that didn’t exist in the past, DeFi improves upon the services that traditional financial systems currently provide. DeFi services available today include lending, exchanges, stablecoins, derivatives, bundling, payments, tokenization, and funding, among others.

We will briefly the leading players in these areas. Since the DeFi landscape is rapidly evolving, we can be sure to see new players enter the market while existing ones leave.

Through InstaDApp, users can manage debt positions, collateralize crypto assets, and swap tokens. InstaDApp also makes it possible for users to collateralize multiple tokens and earn interest for staking DAI.


These are digital assets designed to address the price volatility of crypto. This method of cushioning the asset from crypto fluctuation is done by pegging stablecoins to reliable fiat currencies or a basket of assets. Stablecoins can be used as a medium of exchange and a store of value.


TrustToken’s TrueUSD is a stablecoin pegged on the US Dollar. TrustToken facilitates the deposit of USD to third-party escrow accounts before each TrueUSD is minted. The concept is to make sure that the amount of TrueUSD in circulation equals the USD in TrustToken’s reserves. TrustToken also offers asset tokenization services to allow fractional ownership of assets traded in exchanges globally.


Dai is a decentralized stablecoin pegged to USD. It means that each DAI is worth roughly one dollar. The goal is to reduce the price volatility of DAI compared to other coins. To support this, a system maintains stability of DAI through functions such as the addition and modification of existing Collateralized Debt Positions (CDP) and customization of risk and sensitivity parameters.

Derivative Protocols and Prediction Markets

Prediction markets are blockchain platforms where users can buy or trade their predictions on the possible outcomes for crypto-related or other events.


Augur is a decentralized oracle and prediction market protocol built on Ethereum. Augur rewards users who make correct predictions on topics ranging from crypto, sports, agriculture, stocks, and even the weather. Every time a user makes a prediction, smart contracts take care of the business logic that handles information recording on the blockchain, until an outcome for a specific event happens. Payouts are automated, and the whole process is not influenced by external parties.


Gnosis is a decentralized prediction market platform on Ethereum. It utilizes aggregated information predicted by users to determine a possible outcome for future events. Users can earn tokens by correctly predicting the answers for questions posted on the platform. Gnosis functions under three development layers: a core layer, service layer, and applications layer. The core layer is founded by smart contracts for events, outcome tokens, settlement, and other market logic. Gnosis has two tokens, the Gnosis (GNO) and OWL. GNO tokens are capped at 10 million tokens, and are traded in exchange markets. When users lock their GNOs in smart contracts, they receive OWL tokens which they can use to pay fees on Gnosis applications.


CDx is a protocol for the issuance, trade, and resolution of tokenized credit default swaps on the Ethereum. CDx also follows the 0x framework and lets perform  transactions off-chain while keeping the settlements and recording on-chain.


Daxia offers a decentralized exchange that lets users issue long and short trading positions on several crypto assets, without needing to own them. Daxia uses smart contracts to ensure accessibility and transparency.
