Web3 is a term that refers to the decentralized and distributed internet that uses blockchain technology and other peer-to-peer protocols to create a more open, transparent, and fair online environment. Web3 includes various applications and platforms that run on decentralized networks, such as decentralized finance (DeFi), decentralized applications (DApps), non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs).
DeFi is a subset of Web3 that focuses on providing financial services without intermediaries or central authorities. DeFi leverages smart contracts, which are self-executing agreements that run on blockchains, to enable users to lend, borrow, trade, invest, and access other financial products in a permissionless and trustless way. DeFi aims to create a more inclusive, efficient, and innovative financial system that is open to anyone with an internet connection and a crypto wallet.
One way to understand the difference between Web3 and DeFi is to compare them to the layers of a cake. Web3 is the base layer that supports the entire cake. It consists of the infrastructure and protocols that enable decentralized communication, computation, and coordination. DeFi is one of the layers on top of Web3 that adds specific functionality and value. It consists of the applications and platforms that offer decentralized financial solutions. There can be other layers on top of Web3 that are not related to finance, such as social media, gaming, identity, and governance.

Another way to understand the difference between Web3 and DeFi is to compare them to the domains of innovation. Web3 is a broader term that encompasses the entire domain of decentralized technologies, such as blockchains, DApps, NFTs, and DAOs. DeFi is a narrower term that encompasses only the domain of decentralized finance, which is built on top of an existing smart contract platform, such as Ethereum. Essentially, DeFi and the decentralized internet (Web3) are two separate but related areas of technological innovation.
Web3 and DeFi are both important and exciting developments in the crypto space that have the potential to transform the web and the world. By understanding their differences and similarities, we can better appreciate their contributions and challenges. DeFi is one of the main use cases of Web3, as it enables a more inclusive, efficient, and secure financial system that is accessible to anyone with an internet connection. Web3 also benefits DeFi by providing a more robust, scalable, and interoperable infrastructure that supports innovation and collaboration in the DeFi space.
Some of the inherent challenges on both innovations is that it requires a high level of technical knowledge and financial literacy from users, who need to understand how the underlying protocols work, how to manage their private keys and wallets, how to assess risks and rewards, and how to deal with volatility and complexity. Moreover, defi and web3 also need to educate regulators, policymakers, media, and the general public about the benefits and challenges of these new technologies, in order to foster trust, awareness, and adoption.
Defi and web3 operate in a largely unregulated space that poses legal and compliance risks for both users and developers. For example, defi platforms may be subject to anti-money laundering (AML) and know-your-customer (KYC) regulations, while web3 platforms may face issues related to data privacy, intellectual property, and content moderation.
Defi and web3 applications are vulnerable to various types of attacks, such as smart contract bugs, oracle manipulation, flash loan exploits, and front-running. These attacks can result in huge losses for users and damage the reputation of the ecosystem. Therefore, defi and web3 developers need to adopt rigorous testing, auditing, and monitoring practices to ensure the security and reliability of their code and systems.
