The Good: Advantages of Web3
- Decentralization:
Web3 is based on the principle of decentralization, which means that no central authority or intermediary controls or governs the system. It relies on distributed networks of nodes that communicate and cooperate with each other to maintain and secure the system. This decentralized nature of Web3 enhances its inherent security by reducing single points of failure and vulnerabilities that hackers or malicious actors can exploit. For example, if one node or server goes down or gets compromised, the rest of the network can continue to function without disruption. Decentralization also increases the resilience and robustness of the system, as it can withstand attacks or failures that would otherwise cripple a centralized system. - User Data Ownership:
Web3 empowers users to have more control over their data and privacy by enabling them to decide who can access, use, or share their data. Unlike the current web, where users often give up their data and privacy to centralized platforms or intermediaries in exchange for services or convenience, Web3 allows users to own and manage their data and digital assets. Using encryption, zero-knowledge proofs, or self-sovereign identity systems, Web3 platforms and applications are able to protect user data and privacy and avoid centralized data breaches or leaks that can expose their personal or sensitive information to unauthorized parties.
- Transparency and Trust:
Web3 leverages blockchain technology to create transparent and auditable systems that can reduce fraud and corruption. Blockchain is a distributed ledger that records transactions or events in a secure and immutable way. The blockchain network verifies every transaction or event and cannot be altered or deleted once recorded. This creates high levels of transparency and trust among users and participants, as they can verify the validity and authenticity of the information stored on the blockchain. As the backbone of Web3, this transparency of blockchain demonstrates the transparency of Web3 platforms and services. - Collaboration and Innovation:
Web3 supports a thriving ecosystem for decentralized apps, which can provide fresh approaches to a range of problems. Decentralized applications, which operate on decentralized platforms or protocols like Ethereum, can provide customers with numerous benefits, including lower costs, quicker transactions, a better user experience, or increased functionality. By enabling developers to build on top of pre-existing platforms or protocols, share code and resources, and merge communities and networks, Web3 promotes developer collaboration.

The Bad: Challenges and Risks of Web3
- Smart Contract Vulnerabilities:
Smart contracts are self-executing agreements running on blockchain platforms like Ethereum. Smart contracts can automate transactions, enforce rules, or facilitate interactions between users and applications. However, smart contracts are also prone to coding errors, vulnerabilities, and exploits that can lead to financial losses or system disruptions. For example, in 2016, a hacker exploited a vulnerability in the DAO smart contract and stole over $50 million worth of Ether. In 2017, a bug in the Parity wallet smart contract accidentally froze over $150 million worth of Ethereum. Similarly, in 2021, a hacker exploited a Poly Network cross-chain protocol vulnerability and stole over $600 million worth of cryptocurrencies. These incidents demonstrate the severity and impact of smart contract vulnerabilities and the need for improved security measures and practices. - Regulatory and Legal Concerns:
Web3 operates in a largely unregulated and uncertain legal environment, which may pose challenges for users and developers. As the ecosystem preaches freedom and less regulation, Web3 technologies may not comply with existing laws or regulations in different jurisdictions, resulting in legal disputes, liability issues, or consumer protection concerns. For example, Web3 platforms or applications may not adhere to anti-money laundering (AML) or know-your-customer (KYC) requirements, which may facilitate illicit activities such as money laundering, tax evasion, or terrorism financing. Web3 platforms may also not respect intellectual property rights, data protection laws, or consumer rights, which may infringe on the rights or interests of users or third parties. These issues jeopardize Web3’s security and trustworthiness and endanger the privacy and rights of its users.
- Phishing and Social Engineering:
Phishing and social engineering are two of the most common tricks that malicious actors employ to steal cryptocurrency from people. Phishing occurs when con artists send emails or texts that appear to be from a legitimate source, like a cryptocurrency exchange or wallet provider. The text will often contain a link that, when clicked, will direct the victim to a fake website that mimics the legitimate one. Once the victim enters their login credentials on the fake website, the scammer can steal and use it to access their cryptocurrency accounts.
An example of a recent phishing scam in the web3 space is the Inferno Drainer scam service provider, which has facilitated over 689 phishing websites, targeting several popular crypto and NFT projects, since March 27. According to a Web3 scam detection firm, this notorious scam vendor has already stolen about $5.9 million in assets and targeted at least 4,888 victims. This is just one example of the many phishing attacks that occur in the Web3/blockchain space each year.
- Wallet Security Compromise:
Wallets are software or hardware devices that store users’ private keys and allow them to access their cryptocurrencies or digital assets. With the potential value of cryptocurrencies, crypto wallets are often plagued with various risks of hacks and malware, with keyloggers deserving an honorable mention. Keyloggers are a type of malware that records every keystroke that a victim makes on their computer. The attacker can then use this information to obtain the victim’s cryptocurrency passwords and other private data. This risk of wallet compromise gets more serious by the day, making it one of the most feared disadvantages of Web3.
