In a candid dialogue with Anndy Lian, Binance founder Changpeng “CZ” Zhao offered a nuanced, experience-driven take on two of crypto’s most persistent tensions: privacy and decentralization. Drawing from years of navigating regulatory scrutiny, technical constraints, and market volatility, CZ framed these challenges not as philosophical abstractions but as engineering and policy problems demanding pragmatic solutions.
Privacy as infrastructure, not ideology
CZ opened by affirming privacy as a basic human right, even for mundane, lawful behaviors like shopping habits or messaging. He criticized the excessive transparency of most blockchains, especially when KYC-compliant exchanges link real-world identities to on-chain activity, creating comprehensive surveillance profiles. This overexposure, he warned, introduces systemic risks far beyond compliance obligations.
While championing privacy-enhancing technologies like zero-knowledge proofs, CZ acknowledged the legitimate need for law enforcement to investigate illicit conduct. He insisted that striking the right balance shouldn’t be outsourced solely to regulators. Instead, the ecosystem, including developers, users, and builders, must co-create norms and tools that uphold both civil liberties and public safety.
He extended this critique to DeFi, calling out the practice of broadcasting trades in real time. Public order visibility, he argued, undermines market integrity. It lets adversaries reverse-engineer strategies and front-run sophisticated players. Serious traders do not reveal their hands, he noted, whether on Wall Street or Binance, preferring discreet execution to avoid price impact. Real-time transparency often serves manipulators, not market efficiency.
Decentralization as a spectrum, not a checkbox
CZ pushed back against the binary framing of “decentralized versus centralized.” Instead, he described decentralization as a multidimensional spectrum shaped by validator distribution, governance models, team influence, and mining concentration.
He offered concrete examples. Ethereum’s protocol is technically decentralized, but certain figures like Vitalik Buterin retain outsized influence. Bitcoin benefits from pseudonymous origins and distributed mining, but hash power remains concentrated in a handful of pools. Economic incentives, not just architecture, prevent collusion. True decentralization emerges from aligning human behavior with protocol design.
He also highlighted a critical trade-off: scalability versus distribution. More nodes often mean slower performance, a tension evident in Ethereum’s scaling journey. Idealism must meet usability, CZ said. The path forward lies in advancing cryptography and consensus mechanisms to deliver speed, security, and decentralization simultaneously.
Engineering the next paradigm
CZ expressed cautious optimism that innovation will reconcile these tensions. Breakthroughs in cryptographic primitives, consensus algorithms, and network design could enable systems that are private, efficient, and genuinely distributed. While network effects naturally consolidate power, he stressed that long-term resilience depends on intentional, sovereignty-preserving architecture.
He hinted at AI’s potential role, suggesting intelligent agents might one day enhance privacy or coordinate decentralized networks more effectively. Though he offered no roadmap, the implication aligns with emerging convergence trends between AI and Web3.
Ultimately, CZ’s vision eschews absolutism. Privacy is foundational infrastructure. Decentralization is a continuous optimization problem. Progress will come not from ideology alone but from relentless, grounded engineering. For builders, investors, and policymakers alike, his framework offers a sober, actionable compass for the next era of digital finance.
