As a researcher and Associate Professor at Columbia University with a background in computer science, I have witnessed firsthand the evolution of the internet from its centralized web2 form to the promising decentralized web3 landscape. The potential benefits of web3 are undeniable, but the intersection between these two systems presents unique challenges that must be addressed to ensure a safer digital ecosystem.
Web3, a new generation of internet, stands as a symbol of hope for a safer and more transparent online world, tackling privacy and data control concerns that have been persistent issues in the centralized web2 environment. However, as web3 continues to grow, it frequently encounters web2 networks in potentially harmful ways. This overlap serves as a breeding ground for novel cyber threats. If neglected, these threats could potentially weaken the very security that web3 aims to uphold.
Moving from web2 to web3 may seem attractive to tech fans, but the process isn’t smooth or straightforward, and it leaves room for cybercriminals to exploit vulnerabilities. For web3 to create a safer digital environment, it needs to address and strengthen its inherited weaknesses first.
Critical vulnerabilities at the web2-web3 intersection
Web2 and Web3 present fundamentally distinct concepts for the internet. While Web2 is built on centralized servers and information gathering systems that empower a handful of major companies, Web3 aims to democratize control by transferring data ownership to individual users via blockchain, a decentralized ledger technology.
In essence, while these two systems (web3 and web2) may appear distinct, they are actually intertwined in many ways. Numerous web3 applications continue to utilize web2 infrastructure such as domain names, storage solutions, and APIs. This interdependence leaves web3 vulnerable to the centralized vulnerabilities inherent in web2. For example, a web3 platform that stores data off-site with a cloud provider could be at risk of a server breach. Additionally, web3 platforms featuring web2 interfaces remain susceptible to phishing attempts and DNS manipulation.
Phishing exploits: Web2 weaknesses in web3 environments
In the world of web2, phishing has posed a persistent danger. In the realm of web3, this scheme persists: deceitful individuals create fraudulent user interfaces resembling authentic platforms. They dupe unsuspecting users into disclosing their private keys or endorsing malicious transactions.
These attacks exploit vulnerabilities in web2 systems, like fake domain names and bogus emails, to trick users into believing they’re using a genuine decentralized platform. For instance, a phishing attempt on a DeFi platform could employ a counterfeit web2 site to infiltrate web3 wallets and pilfer funds. This blending of the two networks provides malicious actors with opportunities to mix traditional phishing methods with modern technologies, which can pose serious risks for users who mistakenly think that decentralization is their only protection.
Benefits of web3’s transparency and decentralization
In a nutshell, although there are potential risks associated with it, web3 presents optimism for a safer internet due to its decentralized and transparent infrastructure. The foundation of web3, blockchain, is an unalterable record system that resists manipulation more robustly than typical web2 databases. By implementing smart contracts, the need for intermediaries who might be susceptible to corruption is eliminated. Furthermore, decentralized identity systems empower users to manage their digital identities, minimizing the potency of phishing attempts.
Beyond this, the transparency of web3 enables users to check transactions and inspect systems instantly, providing a high degree of security and responsibility that is challenging to attain in the obscure architectures of web2. By dispersing control among numerous nodes, web3 minimizes the risk of extensive data leaks, a problem frequently encountered in centralized structures.
Accelerating web3 adoption to mitigate online security risks
To effectively address the fresh security concerns arising from the integration of web2 and web3, the tech community should prioritize the swift implementation of completely autonomous network structures. As web3 still relies on certain aspects of web2 for support, it will persistently be susceptible to combined attacks that leverage the vulnerabilities present in both systems.
Currently, it’s becoming increasingly clear that fully decentralized systems can significantly boost security. For instance, in the Decentralized Finance (DeFi) sector, transactions occur directly between users, eliminating the need for intermediaries and thus minimizing the risk of third-party manipulation. Moreover, applications (dApps) developed on blockchain networks enable users to engage with platforms securely without conventional login methods or centralized data storage systems.
As a researcher delving into the realm of web3, it’s clear that we stand on the precipice of its immense potential. However, actualizing this potential is not a trivial task. It necessitates unwavering dedication from developers and industry titans to construct a self-governing digital infrastructure, disconnected from the traditional web2 system. This commitment translates into investing in decentralized storage systems, identity verification methods, governance models, and other comparable platforms. The ultimate objective is to minimize risks prevalent in the current hybrid ecosystem, thereby fostering a more robust and secure digital environment.
As an analyst, I’d put it this way: I, myself, am Ronghui Gu – a co-founder of CertiK and an Associate Professor in the Computer Science department at Columbia University. My academic journey includes earning a Ph.D. in Computer Science from Yale University and a Bachelor’s Degree from Tsinghua University. In my role as the main architect and developer of CertiKOS and SeKVM, I have been honored with various accolades, such as the OSDI Jay Lepreau Best Paper Award, the SOSP Best Paper Award, two Amazon Research Awards, a CACM Research Highlight, and a Yale Distinguished Dissertation Award.
