2025 will be the year rollups go ZK. Making Ethereum the programmable blockchain of choice for both retail and institutional users 🧵

Breakthroughs like @Optimism- @SuccinctLabs and @RiscZero Kailua are making zero-knowledge proving systems viable at scale. And that changes everything.

To become the decentralized world computer, Ethereum needs three things: 1.Credible neutrality 2. High performance 3. Interoperability

@ethereum has #1. Ethereum is scaling into #2. ZK is about to unlock #3.

Right now, Ethereum’s rollup ecosystem doesn’t feel like one chain. It feels like many isolated chains with constant bridging. That’s the real UX gap compared to Solana.

The bottleneck? Most rollups today are optimistic. They rely on fraud proofs that require a 7-day waiting period to finalize withdrawals. That kills UX, and makes bridges slow, capital-intensive, and expensive.

ZK rollups solve this. They use validity proofs, which enable 1-hour finality. This is a game-changer for interoperability. As beautifully explained by our very own @forrestnorwood.

Shorter finality means: - Fast bridges become 168x (yes, lots) more capital efficient - Inter-rollup transfers can happen same-day - UX starts feeling like one chain Bridging becomes cheap, seamless, invisible (As it is supposed to be).

Historically, ZK was hard to build with. But that’s changing fast: - OP-Succinct lets any OP rollup go ZK in days - RISC Zero Kailua enables gradual ZK-optimistic hybrids like @build_on_bob. All while keeping EVM compatibility.

2025 will be the year Ethereum rollups go ZK. The biggest ones, where transaction volume justifies the proving cost, will lead the way. As ZK costs fall, the rest will follow. So what does this mean for Ethereum? Find out in our blog post:
