Ethereum co-founder Vitalik Buterin opened Devcon 8 in Mumbai by calling for hardware that people can verify and for stronger privacy protections across the technology stack. He did not unveil a token or product; instead, he described a problem: modern technology asks users to trust too much and lets them check too little.
Devcon 8 opened on November 3, 2026, at the Jio World Centre in Mumbai. It is the first time the annual Ethereum developer conference has been held in India.
Six areas where trust breaks down
Buterin framed his keynote around trust, which he presented as the central challenge facing modern technology. He split that challenge into six areas: verified operating systems, open silicon, self-sovereign health tech, free discourse, private communication, and trustworthy AI.
His proposed tools were formal verification, open-source designs, and cryptographic proofs. According to the research summary of the keynote, these are areas the Ethereum Foundation intends to push forward, naming trustworthy AI and formally verified operating systems in particular.
Buterin told the audience that people need to be able to trust their operating systems and their hardware, and that the answer is something everyone will need to work out together.
The hardware wallet problem
Hardware wallets were Buterin’s most concrete example. These devices exist to keep crypto keys safe and away from internet-connected computers. The catch, in Buterin’s framing, is that many of them are uninspectable: owners cannot easily confirm what the chip inside is doing.
He warned against relying on opaque devices and condensed the point into one line: “Not your silicon, not your life.”
Buterin stressed that users should be able to have assurance in their technology without intrusive verification measures. The goal is not more surveillance in the name of security, but hardware whose trustworthiness can be checked without users giving up their privacy.
According to the research summary, the remarks line up with ongoing Ethereum Foundation work on hardware security.
Why Ethereum is talking about chips and health tech
Ethereum’s founding pitch was to reduce dependence on trusted third parties. Blockchains replaced the need to trust a bank’s ledger with a public, verifiable one.
Buterin’s keynote extends that philosophy downward and outward. If the blockchain is verifiable but the phone, chip, or operating system running the wallet is not, the trust problem has simply moved somewhere else.
The research ties the timing to wider anxiety about data privacy and the potential for AI to manipulate people. It also points to recent high-profile security breaches and incidents linked to AI and cyber threats.
The conference agenda reflects the same shift. Devcon 8 runs until November 6, and its sessions center on auditable and decentralized alternatives to today’s technology, not on immediate token releases or product launches. The stated aim is to carry Ethereum’s core principles into hardware, health technology, and AI.
