Vitalik Buterin Calls for Full‑Stack Openness and Verifiability to Secure a Digital Future

Ethereum co-founder Vitalik Buterin published a blog post advocating for “full‑stack” openness and verifiability across software, hardware and bio systems to preserve freedom and security as the internet becomes indistinguishable from real life.

Buterin argues that open source code, verifiable hardware, and privacy‑preserving cryptography (ZK‑SNARKs, FHE, differential privacy) are essential to prevent centralization, baked‑in backdoors and supply‑chain vulnerabilities that concentrate power and erode trust. He cites lessons from COVID vaccine inequalities, threats from proprietary health and BCI systems, and risks in electronic voting and forensic evidence to show why civic, commercial and public‑safety tech must be inspectable. Proposals include secure open operating systems and hardware wallets, locally verifiable chip scanning, affordable environmental and bio sensors, formally verified software, and targeted open stacks for high‑security, non‑performance‑critical use cases to bootstrap broader adoption.
