Decentralized Finance (DeFi)

There are three key benefits that make DeFi attractive:

1. Autonomy. Due to the decentralized framework, there’s a reduced administrative overhead, less regulatory scrutiny, and fewer intermediaries, empowering users to manage financial services independently.
2. Transparency. Due to the nature of blockchain technology, user identities are somewhat private (however, transaction records are publicly viewable), making it difficult to alter records.
3. Lower costs. Operations like lending or borrowing money directly are simpler, allowing both parties to set interest rates without going through extra costs with banks. 

No, decentralized finance doesn’t guarantee complete anonymity. Governments and official law enforcement agencies can access and trace transactions if needed (while protecting an individual’s financial interests). However, in general, transactions do not display an individual’s name.

DeFi applications are programs that are easily downloadable on a phone or computer. They are built to interact with blockchains without involving a third party, automating user transactions. This is a huge benefit since the blockchain operates on a global network; users can both send and receive financial services from anywhere in the world.

The blockchain consists of blocks that are linked together by the information in each block, which is why the term “blockchain” was used when describing this technology. From the end-user’s perspective, an application, or a wallet is used to interact with the blockchain. All crypto wallets have private keys. They work like passwords and are required to access crypto. The infrastructure makes all transfers on the blockchain irreversible, ensuring security when it comes to crypto transactions. 

DeFi can be used in various ways. Some common examples include:

• Loans. This sometimes includes options like flash loans that don’t require intense paperwork compared to traditional banks. 
• Trading. Buying and selling crypto assets, often by using decentralized exchanges (DEXs), which allow users to trade directly from their wallets.
• Insurance. There are various decentralized platforms that offer insurance for smart contract failures, travel delays, among other insurance cases, much like how traditional insurers work. The claim payouts are fast because they pool funds from users. 
• Cross-board payments. Using blockchain, businesses can offer international payments via fast and simple transactions. This is especially beneficial for people who are working abroad and want to send money to their families back home. 

DeFi helps companies expand and offer a digital alternative to traditional banks, turning cash into digital currencies, such as Bitcoin. It minimizes the costs, leading to a more open and accessible financial system, opening the door to anyone willing to participate, no matter their location. This helps include unbanked populations.

The main difference between DeFi and CeFi, or Centralized Finance, is centralization. CeFi relies on legal frameworks and intermediaries, such as centralized exchanges or banks. So, for example, on a centralized exchange (CEX), such as Binance, all crypto trading orders are processed through a central platform. Users register on these exchanges and trade cryptocurrencies within the same platform. 

In contrast, DeFi operates on decentralized networks using blockchain technology, such as Ethereum and smart contracts. This enables users to trade via peer-to-peer financial products or decentralized applications (DApps), giving users full control over their crypto assets.

No. Most DeFi apps don’t require users to undergo Know Your Customer (KYC) checks, which require users to prove their identity online when approving their wallet or creating a new account. 

Yes. Centralized exchanges are regulated and face the same scrutiny as traditional financial service providers. Due to their status as money services businesses (MSBs) and their requirement to comply with the Bank Secrecy Act (BSA), they must implement KYC procedures, conduct due diligence, and comply with anti-money laundering (AML) regulations.
