Introduction
The shift from Web 1.0 to Web 2.0 introduced businesses to new security risks. Now, as companies explore the world of Web3, they must navigate a fresh set of vulnerabilities. Web3 is a vision for a decentralized and collectively owned web. It promises a more secure environment, but businesses must take precautions to avoid potential security threats.
The Core Concepts of Web3
Web3 operates on decentralized databases that require majority consensus for any changes. Unlike Web 1.0 and Web 2.0, where users can only read or read-write, Web3 allows users to read-write-own their data. This is made possible through key principles:
- Decentralization: Web3 applications are distributed across a network of connected nodes, eliminating a central authority or controller.
- Consensus: Web3 relies on network consensus to validate transactions and updates. Blockchain technology uses mechanisms like proof-of-work and proof-of-stake for consensus.
- Implicit Trust: Web3 ensures data integrity through cryptography, where data cannot be altered or removed without agreement from the supporting network.
Web3’s decentralized and trust-based approach makes it more secure than Web 2.0. The blockchain ensures that clients receive the exact data they request without the need to trust a centralized provider.
How Businesses Are Using Web3
Businesses are exploring various possibilities with Web3, including:
- Blockchain and Decentralized Applications (DApps): Blockchain technology allows businesses to write decentralized applications (DApps) that use a blockchain to execute transactions. Smart contracts, stored on the blockchain, provide the logic for DApps.
- Decentralized Finance (DeFi): DeFi enables users to access financial services without relying on centralized authorities like banks. DeFi protocols, built on blockchain technology, offer services like loans, trading, and earning interest.
- Distributed, Decentralized File and Data Storage: In addition to blockchain, businesses are utilizing protocols like the Interplanetary File System (IPFS) for decentralized storage. IPFS provides a distributed file system that ensures data remains reliable and accessible.
The Biggest Security Risks of Web3
While Web3 offers enhanced security, it also introduces certain risks:
- Lack of API Query Encryption and Verification: Many Web3 applications rely on API calls that often lack encryption and verification, exposing them to on-path attacks and data interception.
- Smart Contracts Hacking: Flawed smart contracts can put user data and funds at risk. Poorly coded smart contracts have led to major financial losses.
- Privacy Concerns for Decentralized Data Storage: Data stored on a blockchain is accessible to any connected node, raising privacy concerns.
- Account and Mobile Wallet Theft: Attacks on cryptocurrency or NFT wallets are a common occurrence, often due to compromised private keys.
- Protocol and Bridge Attacks: Protocols like bridges, which facilitate transfers between blockchains, can become targets for attacks.
- Slow Updates: Patching security flaws in Web3 can be slow as changes require network-wide consensus.
- Typical Web 2.0 Risks: Web3 front-ends are still vulnerable to risks such as credential theft, cross-site scripting, and code injection.
Best Practices for Protecting Web3 Applications and Infrastructure
To safeguard Web3 applications, businesses should consider the following best practices:
- API Query Encryption and Signing: Encryption and digital signing of API queries and responses are essential for protecting application data.
- Web 2.0 Security Measures: Leveraging web application firewalls (WAFs), bot management, and other Web 2.0 security measures can mitigate risks.
- Strong Code Auditing Before Deployment: Conduct thorough code audits to identify vulnerabilities before deployment. Due to the slow update process of Web3, identifying flaws in advance is crucial.

FAQs
Q: What is Web3?
A: Web3 is a vision for a decentralized and collectively owned web where users not only contribute data but also own their data.
Q: How does Web3 differ from Web 1.0 and Web 2.0?
A: Web 1.0 is read-only, allowing users to obtain data. Web 2.0 is read-write, enabling users to contribute data. Web3 is read-write-own, granting users ownership of their data.
Q: What are the main security risks of Web3?
A: The main security risks of Web3 include lack of API query encryption and verification, smart contract hacking, privacy concerns for decentralized data storage, account and mobile wallet theft, protocol and bridge attacks, slow updates, and typical Web 2.0 risks.
Q: How can businesses protect Web3 applications and infrastructure?
A: Businesses can protect Web3 applications and infrastructure by implementing API query encryption and signing, leveraging Web 2.0 security measures like WAFs and bot management, and conducting thorough code audits before deployment.
Conclusion
Web3 presents businesses with exciting opportunities but also introduces security challenges. By understanding the core concepts, risks, and best practices associated with Web3, organizations can navigate this new landscape more securely.
