With the rapid development of the Web3 field, more and more Web2 programmers are crossing over into this new world full of opportunities. These developers, with their solid engineering background, are achieving a qualitative leap in technology within the Web3 space, elevating themselves from ordinary developers to the so-called "on-chain scientists."

Although the technical diagrams circulating in the industry have become blurred due to multiple forwards, this does not affect the significant breakthroughs in actual technology in the Web3 field. For example, traditional security mechanisms such as slider verification have been systematically compromised, marking an important milestone in Web3 security.

The leap in this capability primarily stems from the complexity of the underlying Web3 technologies. In terms of smart contract security, developers need to master how to defend against new types of vulnerabilities such as reentrancy attacks and integer overflows, which far exceed the security scope of traditional web development. At the same time, the technical toolchain has also undergone significant upgrades, shifting from the basic CRUD logic of Web2 to the application of more complex Solidity contract development and formal verification tools.

It is worth noting that the offensive and defensive game in the Web3 field has also escalated to a new level. Hackers have begun to use innovative methods such as flash loans and oracle manipulation to break through traditional verification systems, forcing developers to rebuild the entire security architecture based on the principle of "zero trust."

From a technical perspective, the failure of slider verification is merely a superficial phenomenon; behind it lies a complete paradigm shift in Web3 regarding identity verification, data sovereignty, and the security of smart contracts. Although Web2 developers have an advantage in systems engineering experience, if they overlook the unique aspects of on-chain security (such as private key management, governance vulnerabilities, etc.), they may still fall into new types of offensive and defensive traps.

Looking to the future, despite the astonishing speed of technological iteration, we must remain vigilant against the tendency to overly rely on tools. True technological breakthroughs should organically combine the rigorous development processes of Web2 with the innovative mechanisms of Web3, thereby maintaining a leading position in this rapidly evolving field.
