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).
Key Takeaways
Brave’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. ...

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.

Dude, [chuckles] I cannot believe that in recording this, we asked the chief architect of Netscape to restart his browser to see if that fixed the problem. [laughing]
Who got the truth? [upbeat music] Is it you? Is it you? Is it you? Who got the truth now? Is it you? Is it you? Is it you? Sit me down, say it straight. Another story on the way. Who got the truth?
Welcome to this special episode of Acquired, the podcast about great technology companies and the stories and playbooks behind them. I'm Ben Gilbert, and I'm the co-founder and managing director of Seattle-based Pioneer Square Labs, and our venture fund, PSL Ventures.
And I'm David Rosenthal, and I am an angel investor based in San Fransicko.
And we are your hosts. Today's episode is a mashup between one of the newest things on the internet and the oldest things on the internet.
[laughing]
Our guest today is Brendan Eich, CEO of the Brave Browser, an application right at the heart of the rapidly emerging Web3 world. It is arguably the single largest blockchain-based app, with over fifty million monthly users. However, Brendan is no new kid on the block. He holds the credential of inventing JavaScript, a source of much joy and also much pain for many of you out there, and Brendan was the chief architect of Netscape, and eventually became the CEO of Mozilla, the makers of Firefox.
So you're saying fifty million MAUs is nice, but Brendan wants this to go a lot higher. [chuckles]
It's crypto nice, but it's not browser nice.
Yet. Yet!
Yes, but it is rapidly growing. We had a, uh, wide-ranging conversation with Brendan that you'll hear today, that bridged this old world and the new in some really fun ways. And speaking of the new, we are so excited to announce our presenting sponsor for all of these special episodes, the Solana Foundation.
Yes, so pumped!
I know. Well, for listeners who have been living under a rock, uh, Solana is a global state machine, and the world's most performant blockchain, and you'll hear about them on this episode. Now, what does that mean? It means that developers can build applications with super low transaction fees and low latency, without compromising composability, since it's all on one single chain with a global state. Solana is capable of processing tens of thousands of smart contracts at once, and by proof of history, a distributed clock that unlocks low latency, sub-second finality. It has a really clever mechanism. It does all this stuff really fast. It's very, very cool.
You can hear all about it on our episode with founder and CEO, Anatoly.
But we are gonna talk, in true decentralized fashion, to some of the folks building the protocols and decentralized applications on top of Solana. So we have with us today Jay, a developer at Project Serum. So Jay, what is Project Serum?
Serum is a central limit order book-based exchange on the Solana blockchain. In the past, crypto traders would use centralized exchanges that lacked composability, and also gave centralized entities unilateral control of their funds. Eventually, traders moved on-chain in the form of decentralized finance, using new crypto primitives, such as AMMs. These primitives lacked the same capital efficiency that traders were used to on centralized exchanges. Serum now brings the central limit order book on-chain. It leverages Solana's parallel architecture to offer thousands of markets that operate concurrently, giving traders the low-latency experience they're used to in traditional financial markets. This enables things like spot, spot margin, perpetuals, and dated futures to be traded on-chain in a completely composable manner through applications such as Mango Markets, which are protocols built on top of Serum.
