How Fast Confirmations Will Improve Rollup UX with Ben Fisch and Matt Pearring

Today's episode explores how the rollup-centric vision for Ethereum brought massive scalability gains, but also new challenges - from fragmented liquidity to complex coordination across execution layers.

Enter Espresso and Arbitrum's collaboration, tackling these hurdles head-on. At its core is Espresso's fast confirmation system, enabling rollups to validate transactions with both speed and strong security. This unlocks true interoperability without sacrificing decentralization.

Their work extends to democratizing sequencers, a critical step toward Ethereum's ideals of neutrality and censorship resistance. By making sequencers accountable while maintaining performance, they're showing how rollups can evolve thoughtfully.

The introduction of standards like ERC-7683 for intent-based interoperability demonstrates how small, strategic improvements can have outsized impact. As Arbitrum pushes toward deeper decentralization, their partnership with Espresso exemplifies how modular innovation can advance Ethereum's vision while keeping things practical.

This isn't just about technical upgrades - it's about shaping how rollups will actually work for users and developers in the real world.

A composable future is coming for Ethereum.
