Web3 security

The World Wide Web is now a fundamental part of our lives, empowering us  with access to information, communication, and a wide array of services. With the advancement of technology, the global network is evolving as well, while the latest iteration of the Internet, Web3, is also gaining momentum. As for Web3, it brings along new features and opportunities, in addition to raising new security issues that need to be addressed so that users and their data are kept safe.

Here we will take a look at what exactly Web 3.0 is, we will cover the main types of risks associated with it, as well as the advantages and disadvantages of this technology.

What is Web3?

Web3 is a term created to refer to the next stage of the Internet, which comes after Web1 and Web2. Web1 was a static web where information was presented but could not be interacted with, whereas Web2 stood for a dynamic web where users could interact with websites and applications. Web3 in turn is a whole new concept where the Internet is decentralized and users are given full control over their data and identity.

Built on blockchain technology, Web3 allows you to create decentralized applications (dApps) that are transparent, secure and tamper-proof. Due to the decentralized nature of Web3, users do not rely on centralized organizations, such as social networking companies, to store their data and communicate with each other. Instead, you can communicate and interact with dApps directly, with no intermediaries or central bodies.

Major risks of Web3

There are emerging risks in Web3 that must be considered to ensure the security of users and their data. Here are the main forms of risks associated with Web3:

  • Smart contract vulnerabilities. Smart contracts are self-executing computer programs that run on the blockchain. These are used in Web3 to automate all kinds of processes, such as the transfer of payments without any intermediaries. However, smart contracts are not infallible, to the extent that those vulnerabilities are exploitable by attackers, which could result in the loss of funds or other malicious activity.
  • Cryptojacking. This is a particular type of cyber attack whereby attackers use a victim’s device to mine cryptocurrencies behind backs. At Web3, cryptojacking can be performed through dApps since users are required to give permission to dApps in order to access their device’s resources.
  • Phishing: This one occurs when attackers trick users into revealing sensitive information, such as login credentials or private keys, by using fraudulent websites or emails. Within Web3, phishing attacks can target dApps or decentralized exchanges (DEXs), causing loss of funds or sensitive data.

Other possible risks of Web3

Apart from the risks mentioned above, Web3 faces a number of other risks that need to be addressed to guarantee its security. Such risks include:

Regulatory risks. Due to the fact that Web3 is decentralized, it is difficult to control. It may pose a challenge for governments to enforce laws and regulations on decentralized platforms, which could lead to illegal activity or abuse.

Governance risks. Decentralized platforms rely on a consensus mechanism to make decisions. Once the consensus mechanism is flawed or manipulated, it can lead to governance risks, such as the majority group controlling the platform and making decisions that benefit it to the detriment of others.

Interoperability risks. Web3 is a fragmented environment with many different blockchain networks and dApps. Unless these networks and dApps can communicate with each other, this can lead to interoperability risks such as reduced functionality or security issues.

Web3 pros and cons

Web3 offers several advantages over the existing centralized network, such as:

With Web3, users now have more control and ownership of their data, meaning they can enjoy a greater level of confidentiality and independence.

Innovation and experimentation. Web3 enables developers to explore new ways of using and implementing applications that were previously impossible or difficult to realize.

Yet Web3 has some disadvantages, in particular:

Complexity and learning curve. Web3-based technologies may seem complex and require specialized knowledge, which may be a barrier for some users.

This stage of Web is still largely unregulated, thereby potentially creating legal and compliance risks.

Web3-based networks are likely to suffer from scalability and performance issues, both of which can lead to slower transactions and higher fees.

What is the outlook for this technology?

As more and more developers and companies explore its potential, the future of Web3 looks promising. It has the power to transform various industries, such as finance, healthcare, as well as supply and logistics. It can also provide increased transparency, security and efficiency, thus saving you money and improving the user experience.

Nevertheless, challenges still exist around scalability, regulation, and interoperability. Both developers and businesses alike should work together to overcome these challenges and ensure safe and reliable Web3 implementations.


Web3 stands for the next era of the Internet, one that will bring new features and capabilities, but will also raise new security concerns. Smart contract vulnerabilities, cryptojacking and phishing represent the main types of risks associated with Web3, meanwhile there are also risks associated with regulation, governance and interoperability.

As good as it is, Web3 is still in its early days, so problems concerning scalability, regulation and complexity are yet to be solved. The potential benefits of Web3, however, make it a technology worth exploring.
