    Pretty sure this was the first ascent of El Capitan in an Espresso t-shirt. Dear crypto twitter, what other wild places has @EspressSys swag made it to?

    The ArbitrumDAO just approved the BoLD upgrade with 210M ARB votes—the most in Arbitrum history. BoLD makes Arbitrum a Stage 2 Rollup, enabling permissionless validation. Major milestone for Ethereum. The next challenge is solving Ethereum-wide Rollup interoperability.

    Today I posted an article outlining how Espresso functions as a marketplace for L2 sequencing that enhances composability while preserving chain independence and sovereignty. Rollups can also now become *based* through integration with Espresso. hackmd.io/@EspressoSyste….

    Ethereum alignment is at an all time high. And as a testament to that it’s cool to see so many L2 leaders come together to embrace the concepts of based rollups and native execution. Based rollups and native rollups are two orthogonal concepts that work very nicely together. 🧵

    epic sequencing call #17! Many founders, including 10 rollup founders, shared their support for based and/or native rollups. Below are some their quotes. 1h45min YouTube recording coming ASAP :) Part 1—based and native rollups Ben Jones from @Optimism: "Let's get this right.

    Rollups were originally framed as a scaling patch for Ethereum. But today they’ve become the new architecture for Web3. Rollups look very similar to traditional web applications. They make it easy for any web app to come onchain by simply publishing its data to a base layer.

    This is disgusting. This industry needs to purge the toxic mindset that would rather see us pump and dump a memecoin off a half-baked idea than build something of real value. That would rather we rug and walk away with 100M than spend years solving Ethereum’s hardest challenges.

    the problem with all of these infra memecoins is that the coin launches 18 months after the narrative dies shared sequencer coin would have ripped in 2022 restaking coin and intents coin would have ripped in 2023 they are obvious zeroes in 2025

    I would love for this to be true as I've worked on verifiable computation for many years. But here are factors limiting its impact alone: 1) It proves the output of computation on some data source, but doesn't help you verify quality/truthfulness of the data source (e.g.

    Yes yes! Don't bridge coins. Just have secure x-chain message passing. Glad others are waking up to this important realization too! But x-chain messages need to be fast, requiring a universally trusted fast-finality layer for L2s. Andrew's article misses some critical points 🧵
