Binance Founder Changpeng Zhao Says “Web3 Will Redefine Security for Web2”
Binance founder Changpeng Zhao warns that even trusted open-source Web2 applications face growing security threats, advocating for Web3 technologies like smart contracts and decentralized apps as long-term solutions to strengthen online security.
CZ reveals Binance is testing a crypto inheritance feature for families to access deceased users' holdings, though he admits the current user experience "sucks" and needs significant improvement before launch.
Binance founder Changpeng Zhao (CZ) has warned the crypto community about the growing security threats in Web2 applications. He stressed that even trusted and open-source software is no longer safe from attackers.
“Web3 will redefine security for Web2,” CZ said on X, urging developers and users to stay alert as hackers become more advanced.
Web3 as the Security Solution
CZ believes Web3 technologies like smart contracts and decentralized applications can fix many of the weaknesses in Web2.
According to him, blockchain can “safeguard digital assets and sensitive data” by removing weak points that attackers often exploit. While he admits Web3 is still at an early stage, he sees it as a long-term solution for stronger online security.
Binance Tests Inheritance Feature
CZ also revealed Binance is testing a new inheritance feature that lets families access the crypto holdings of deceased users.
However, he admitted the feature still needs work:
“Direct feedback (as a user), it sucks. Needs improving,” he tweeted, noting that while the system functions, the user experience is far from ideal.
Community Reacts to CZ’s Warning
CZ’s warning about Web2 security quickly caught attention on crypto Twitter.
Crypto influencer MartyParty agreed, saying open-source repositories must be secured and suggesting that Web2 scripts and code should move on-chain. He even proposed a Web3-powered browser that connects directly to blockchains, removing many of today’s vulnerabilities.
Open Source Debate
Not everyone agreed that open source is the problem. A user known as agentic_t argued that the issue lies in management, not openness.
“The future of secure code lies in reproducible builds, signed releases, hardware-level verification, and strict permission structures,” he said.
This highlights that while Web3 can improve security, best practices in code management are just as important.
Is CZ’s Warning Realistic?
Yes, recent supply chain attacks, such as the one targeting NPM packages, prove that even widely used open-source tools can be hacked.
While open source improves transparency, it doesn’t guarantee safety without verification and strong controls. CZ’s call for Web3-based security reflects the urgent need for new protections as cyberattacks grow more sophisticated.
