Lending and borrowing are not new concepts; people have been borrowing and lending money since ancient times. However, the way we borrow and lend has changed significantly over time. To better understand this article, I recommend reading the one about what money is to make it easy on you.?

There is one thing that all the systems had in common, and it didn’t change over time, this is trust. Without it, it's going to be impossible to even build a financial system. How a person or entity (public or private) is lending if they have a certainty that the money isn’t back with an interest back to the borrower.

The Code of Hammurabi, one of the earliest known legal codes, dates to ancient Babylon around 1750 BCE. The code contained laws related to lending and debt and provided regulations on interest rates and repayment terms. It also outlined punishments for those who failed to repay their debts, including limited slavery for a certain time, and even death in some cases if the crime was committed to a superior social status.

The establishment of modern banking in Europe in the 17th century paved the way for the development of credit and the creation of debt instruments, such as bonds. Banks provided individuals and businesses with access to credit, enabling them to fund investments and projects that they may not have been able to otherwise. All of them were backed by gold, and since gold was hard to move from one place to another or security systems were needed to ensure its existence, different instruments were implemented.

After the de-peg of the US dollar with the gold in the 1970s, the entire system was built only on the trust of the governments, specially the one that had the printing machine would? back and respect people's assets in case of a collapse in the banking system via their central banks.?

Here is a nice video about the foundries of the banking system if you would like to dig more into this topic.?

Traditional finance and the need for improvement:

Today, traditional banking institutions offer a range of financial services, including savings and checking accounts, loans, mortgages, and credit cards. These services provide individuals and businesses with access to the funds they need to invest, purchase goods and services, and achieve their financial goals.

All banking entities are regulated by central banks, yet banks retain independence in determining who to loan money to and the amount. Banks use the money deposited by customers to allocate it to other clients at higher interest rates, with only a small portion of funds held by the bank. The concept of lending is designed to help people and companies grow, creating value within society. However, if many customers request their money from a bank, it can result in a bank run, whereby the bank cannot supply the demand. The 2008 financial crisis was one of the biggest bank collapses in history, triggered by a combination of factors including the subprime mortgage crisis, financial deregulation, and excessive risk-taking by banks and other financial institutions. Numerous banks invested heavily in high-risk mortgage-backed securities that plummeted in value when borrowers began defaulting on their loans.?

This led to traditional financial system criticism for its lack of transparency, high fees, and the concentration of power in the hands of a few big players.

Blockchain technology and the rise of DeFi:

Blockchain technology has revolutionized the way we store, manage, and transfer data. It has also given rise to a new financial system - decentralized finance (DeFi). DeFi refers to financial services that are built on top of #blockchain technology and operate without the need for intermediaries, such as banks or financial institutions.

How lending and borrowing protocols work in the DeFi ecosystem:

#DeFi lending and borrowing protocols enable users to lend and borrow cryptocurrencies without intermediaries in a form of smart contract that runs automatically according to certain pre-established rules, providing a decentralized and trustless alternative to traditional finance. Users can lend their #cryptocurrencies to the protocol, which then lends the cryptocurrency to borrowers. The borrowers provide collateral to the protocol (each protocol accepts different cryptocurrencies), which is held in smart contracts until the loan is repaid. Interest rates are determined by supply and demand (not by any central institution), with rates typically being higher for more volatile or less liquid cryptocurrencies. Often new protocols, in order to attract customers, offer higher returns on investment on paper,always? be careful and do your research as we suggest in this article for your safety. Remember that not everything that shines is gold.

Risk Management comparison between the traditional banking system and the DeFi ecosystem

In traditional banking, the risk management system is centralized and generally well-established, with large financial institutions and regulators managing and overseeing risks such as credit, market, and operational risks. In addition, traditional banks typically offer deposit insurance, government guarantees, and other safety nets for depositors and borrowers.

On the other hand, DeFi protocols operate in a decentralized and trustless environment where risks are managed by various parties, such as developers, auditors, and users. While this offers greater transparency and accountability, it also presents unique challenges in terms of risk management, including smart contract risk, market risk, and liquidity risk.

Overall, traditional banking is generally considered to be a lower-risk investment option compared to DeFi protocols. However, it is important to note that investing in traditional banks still carries some degree of risk, and there have been instances of bank failures and government bailouts, as we have mentioned in the 2008 crisis or the recent events with Silicon Valley Bank to mention a recent bailout, creating a safety net for a total collapse in the banking system as we know it today. This doesn’t mean that risks in the banking systems are things of the past, in the US the FDIC covers you up to $250,000 USD.

In contrast, investing in DeFi protocols can offer higher potential returns but also carries a higher level of risk due to the decentralized and relatively untested nature of the ecosystem.

Ultimately, the decision to invest in traditional banking or DeFi protocols should be based on a thorough assessment of personal risk tolerance, investment goals, and understanding of the risks and benefits associated with each option. It is also important to conduct due diligence and research on any potential investment opportunity before committing funds.

Several security measures should be taken when investing in DeFi lending protocols, such as:

• Use reputable and audited protocols: Choose DeFi protocols that have undergone security audits and are known for their reliability and transparency.
• Conduct thorough research: Before investing in a DeFi protocol, research its history, team, and community to ensure it has a strong reputation and a solid track record.
• Understand the smart contracts: They are the backbone of DeFi protocols, and investors should have a basic understanding of how they work, and any potential risks associated with them, like token volatility.
• Use a hardware wallet: Hardware wallets provide an additional layer of security by keeping your private keys offline and out of reach from hackers.
• Diversify your investments: Like any investment, it's important to diversify your portfolio to reduce risk. Consider spreading your investments across multiple DeFi protocols to minimize the impact of any potential losses.
• Monitor your investments: Regularly monitor your investments and keep track of any unusual activity or suspicious transactions. Stay informed about the latest security issues and best practices in the DeFi ecosystem.

Examples of lending and borrowing protocols:

There are several popular DeFi lending and borrowing protocols in the market today, such as Aave, Compound, and MakerDAO. Aave is an open-source, non-custodial protocol that enables users to lend and borrow cryptocurrencies, while also earning interest on their deposits. Compound is another DeFi lending and borrowing protocol that allows users to earn interest on their deposits while also providing loans to borrowers. MakerDAO is a decentralized lending platform that uses collateralized debt positions to issue loans in a stablecoin called DAI, you can review the article regarding MakerDAO here.

Benefits of DeFi lending and borrowing:

DeFi lending and borrowing protocols offer several benefits over traditional finance. The platform enables P2P lending between network participants and removes any need for third-party involvement.

• Allows lenders to earn interest for lending their crypto assets.
• Offer lower fees, faster processing times, and greater accessibility for users who may not have access to traditional banking services.
• Higher degree of transparency, as all transactions are recorded on a public blockchain.

The emergence of decentralized finance (DeFi) and blockchain technology aims to address some of these drawbacks by providing a decentralized and trustless alternative to traditional finance. DeFi protocols enable users to lend and borrow cryptocurrencies without intermediaries, providing greater accessibility and lower fees. However, as with any financial system, there are risks associated with DeFi lending and borrowing, including smart contract vulnerabilities and the potential for market volatility.

Overall, the lending and borrowing system has come a long way since the Code of Hammurabi and will likely continue to evolve and adapt as technology and society continue to change. In the next coming years, we’ll see more regulations coming into the crypto space to enhance the trust of the general public as it becomes mainstream.? The traditional banking system will also need to accommodate, otherwise it? will lose a significant part of their clientele (and deposits as well).
