Dom and CZ weigh in on future of blockchain security

Changpeng Zhao, widely known as CZ, has once again sparked debate on the future of digital security. In a recent comment, the former Binance chief said that “even open-source software is not safe these days” and argued that Web3 will eventually redefine how security is handled in the systems that underpin Web2. His view carries a note of caution, stressing that despite the rapid growth of blockchain technologies, the industry is still in its early stages.

Dominic Williams, founder of the Internet Computer Protocol (ICP), was quick to respond. He welcomed CZ’s attention on the issue of security but drew focus to a broader perspective. According to Williams, ICP already runs applications such as social media platforms, artificial intelligence tools, and enterprise systems entirely on-chain, alongside more familiar uses like decentralised finance and tokens. He described blockchain as a new technology stack that will soon be enhanced by artificial intelligence capable of writing and deploying code at scale.

The exchange between CZ and Williams reflects two complementary approaches. CZ highlights the vulnerabilities that remain in today’s infrastructure, reminding developers and businesses that the tools they rely on are still exposed to risk. Williams, meanwhile, points to the future, where blockchain could underpin a much wider range of online activity, creating systems that are secure by design rather than patched after the fact.

Both leaders, though coming from different angles, draw attention to a shared truth: security remains central to the success of the next phase of the internet. For some, that means strengthening existing systems, while for others it means building entirely new ones. The dialogue between CZ and Williams shows that both paths are shaping what comes next.
