The threats to web3 security have become significant concerns for the future of web3. The hacking attacks on web3 and smart contracts not only result in financial losses but also raise questions about the trustworthiness of web3. People worldwide view web3 as the next stage in the evolution of the internet. It utilizes technologies like blockchain and smart contracts to offer a decentralized, secure online experience. One of the main promises of web3 is giving users control over their data. As a web3 user, you have the power to decide who can use your data, how they can use it, and for how long. If you don’t approve of a third party’s use of your data, you can revoke their access privileges. On the surface, web3 may seem well-protected against security threats. However, the reality is that web3 and smart contracts security are in a critical state. In the first half of 2023, the web3 industry suffered losses of nearly $656 million. Hacking, rug pulls, and phishing scams were some of the notable attacks. Smart contract vulnerabilities alone accounted for around $264 million in losses, while phishing scams resulted in $108.4 million in losses. Therefore, the web3 world needs security experts and auditors to protect web3 solutions and foster trust. However, it’s important to understand web3 and smart contract security from a hacker’s perspective. In this post, we will explore a roadmap for becoming a certified or ethical web3 hacker.
