WHAT IT’S REALLY ABOUT
Brendan Eich on Brave, privacy economics, and browsers’ next era
- Brendan Eich explains Brave as a Chromium-based browser that blocks trackers by default, improving speed, battery life, and privacy while challenging the surveillance-advertising status quo.
- He traces the web’s tracking problem back to early design choices like third-party cookies and the web’s extreme backward-compatibility pressure, then connects those origins to today’s ad-tech incentives and fraud.
- Brave’s alternative model uses opt-in, on-device ad matching and revenue sharing via Basic Attention Token (BAT), plus an expanding product surface (search, native wallet, multi-chain support).
- Eich argues privacy is not only a right but also a source of economic bargaining power for users; he outlines Brave’s ambition to scale to hundreds of millions of users and move more of its ad verification/accounting on-chain using zero-knowledge proofs (e.g., “Themis,” targeting Solana).
IDEAS WORTH REMEMBERING
8 ideasBrave’s core pitch is felt performance, not ideology.
Eich says users switch primarily because pages load faster, battery/data use drops, and clutter disappears when trackers and ad scripts are blocked—privacy is the enabling principle but speed is the daily sensation that drives adoption.
The web’s tracking problem was baked in early via third-party cookies.
Cookies and embedded resources enabled “pixel” tracking across sites as early as the mid-1990s, and the web’s commitment to backward compatibility made reversing these vectors extremely difficult without breaking the ecosystem.
Browsers are ‘immortal’ because they’re the universal app layer.
Eich argues the browser keeps reasserting itself as the cross-platform runtime for apps and content, especially as screens/input improve and users avoid installing bloated native clients (he cites Slack as an example).
Privacy is also economic power for users, not just personal safety.
Beyond avoiding dossiers, breaches, and surveillance, Eich frames privacy as the prerequisite for users to bargain collectively with network powers—keeping data local enables new market structures and fairer value exchange.
Brave’s ad model avoids front-side tracking by moving ‘decisioning’ into the browser.
Instead of ad networks collecting user data before selecting an ad, Brave distributes the same regional ad catalog to many users and performs matching locally with lightweight ML—users opt in, and advertisers get coarse segmentation without re-identification.
KYC/AML constraints shape Brave’s token design more than technology does.
Eich emphasizes that paying users/creators directly on-chain raises compliance and privacy risks (fingerprinting via transaction patterns), so Brave uses custodial rails in parts of Rewards today while working toward cryptographic approaches (e.g., ZK proofs).
Centralization pressures in Web3 are real, but can be mitigated with cryptography and strong clients.
Responding to Moxie Marlinspike’s critique, Eich agrees servers like Etherscan/Infura are hard to replace for indexing and UX, but believes privacy/security can still improve if clients enforce better terms using cryptographic protocols.
Scaling to hundreds of millions of users is Brave’s path to real leverage.
Eich’s ‘A+’ outcome is ~400M MAUs (continuing recent doubling), unlocking distribution deals, standards influence, and the ability to run a more decentralized, creator-supporting economy across users/advertisers/creators.

5 quotes“Brave is a faster browser because it… blocks all the trackers.”

“We didn’t think about the third-party problem… and that created a tracking vector.”
— Brendan Eich
“Give me six sentences from the most honest man, and I’ll find a way to hang him.”
— Brendan Eich
“Everybody’s doing [privacy] now. They’re putting privacy perfume on without taking a shower.”

QUESTIONS ANSWERED IN THIS EPISODE
5 questionsBrave blocks trackers by default—what are the most common modern fingerprinting techniques you’re seeing now, and what’s hardest to defend against?
Brendan Eich explains Brave as a Chromium-based browser that blocks trackers by default, improving speed, battery life, and privacy while challenging the surveillance-advertising status quo.
You said Mozilla didn’t ship third-party cookie blocking partly due to ‘rocking the boat’—what specific internal debates or trade-offs were most decisive at the time?
He traces the web’s tracking problem back to early design choices like third-party cookies and the web’s extreme backward-compatibility pressure, then connects those origins to today’s ad-tech incentives and fraud.
Brave’s ad catalog + on-device ML avoids front-side tracking; what metrics do advertisers still demand that you refuse to provide on principle?
Brave’s alternative model uses opt-in, on-device ad matching and revenue sharing via Basic Attention Token (BAT), plus an expanding product surface (search, native wallet, multi-chain support).
Can you explain ‘Themis’ in more concrete terms: what exactly is proven in zero knowledge, what’s stored locally, and what ends up on-chain?
Eich argues privacy is not only a right but also a source of economic bargaining power for users; he outlines Brave’s ambition to scale to hundreds of millions of users and move more of its ad verification/accounting on-chain using zero-knowledge proofs (e.g., “Themis,” targeting Solana).
Where does Solana fit technically and economically for Brave—are you using it mainly for cost/latency, developer ecosystem, or something else?
