The next challenge is enabling institutions to settle assets and cash across chains without exposing sensitive data or creating new settlement risk. Linea and @bermudabayzk show that private, atomic and verifiable settlement is possible. Blog post ↓ linea.build/blog/atomic-dvp-…

Another great post from @joechalom and @Sharplink. It is great to see Joseph highlight the remarkable milestone of 1 million lifetime developers that have built or build on Ethereum. Joseph also touches on some key factors that will lead to the many L2s, and private permissioned Besu Ethereum chains becoming fully composable with each other and L1: credible neutrality, modularity, culture and composability. He sketches the synchronous and near-synchronous composability work that the @Linea team is doing and others including @Zisk and @gnosis_ are doing similar work. Atomic bridgeless execution zones and real-time unification of liquidity fragments will be the benefits and a unified extended Ethereum ecosystem will be the major result. ETH will be resident on all of these networks and used to pay fees for inclusion in multi-network activity to synchronizers who aggregate ZK proofs from the various networks. Ethereum is growing into an increasingly globally systemically important infrastructure, and ETH is about to also become globally systemically important as it will be the fuel and currency that powers transactions, storage, staking and many other functions on the world's main global digital asset processing and settlement layer. Amusingly, I found this my DevCon5 Osaka keynote entitled "When 1 Million Eth Devs?" We got there. And the keynote does a pretty decent job of sketching how Ethereum will become systemically infrastructure, from way back in 2019. youtube.com/watch?v=Sp8ZjaWg…

Governance now matters as much as technology in institutional infrastructure. Open source alone is not enough, and code neutrality is what reduces dependency risk and builds long-term trust. @DeclanFox14 of @LineaBuild and @rojotek of @Consensys on the Main Stage at ETHConf.

"The biggest anti-pattern today is the belief that institutions still need their own private, permissioned L1" @DeclanFox14 at @ParisBlockWeek on the Institutional Crypto Stack. ZK proofs changed what's possible. Banks and FMIs can keep their permissioned setup and still connect to Ethereum, without giving up compliance or privacy.

Leading Ethereum stewards @Consensys and @ethereumJoseph have joined DeFi United with up to 30,000 ETH in financial support for the rsETH recovery effort, with ongoing strategic advisory from @Sharplink. Their contributions are a substantial component of the broader DeFi United effort to restore rsETH's backing and normalize market conditions, and the recovery would not be progressing as it is without them.

Building a zkEVM from scratch is tough, especially when writing raw arithmetization constraints by hand. At @LineaBuild, the team built ZK Assembly (zkASM), a custom assembly language to make constraint generation faster and easier. Here is how it works. 🧵👇

The @LineaBuild prover just got cheaper, faster and lighter. Our cryptography team just released Small Fields. Switching to 31-bit Small Fields (KoalaBear) zkASM is a fundamental re-architecture of Ethereum state proving. → Proofs are now dramatically faster & lighter → RAM footprint drops and prover decentralization becomes realistic → We’re one big step closer to real-time finality No security trade-offs. Just pure cryptographic engineering. If you’re a builder working on ZK, L2 scaling or decentralized provers, this is the kind of innovation that changes what’s possible.

Welcome to the Ethereum Economic Zone (EEZ), a framework for synchronously composable rollups. What does that mean? One deployment. Shared liquidity. Single transactions across L1 & L2. Identity verified anywhere. Smart wallets connected everywhere. No additional trust assumptions. This means L2s that are as credibly neutral, economically aligned, and publicly governed as the base layer itself. EEZ furthers Ethereum as the leading decentralized economy.

Our cryptographic researcher @alexand_belling revealed yesterday at @eth_proofs that Linea is moving to RISC-V. After 3 years of directly arithmetizing the EVM, producing a 1000 page spec and one of the most rigorous proving system in production, we’re changing course. Here’s why 🧵

Stablecoin rules in the UK are being finalized, and are at risk of preventing the UK from being globally competitive in the digital economy. For example, the Bank of England is proposing a cap on stablecoin holdings for individuals and businesses. The UK has a long history of being a financial hub. Embracing and encouraging innovation, especially when other countries are moving fast here, is important for maintaining that. The current direction of the rules does the opposite, and will act as an innovation blocker. If you're from the UK you can sign the petition by @StandWCrypto_UK to set out a pro-innovation strategy for blockchain and stablecoins. Link below.

At Linea, we don't just use gnark, we build it. Vortex polynomial commitments now benchmarked at: - 3.7× faster than Plonky3 FRI (CPU) - 9.6× GPU boost on commit - 35.8× GPU boost on open Thanks to @AntChainOpenLab for the hardware acceleration work and to our cryptography team @gnark_team.
Gnark-crypto's Vortex commitment is 3.7× faster than Plonky3's FRI PCS. Our Hardware team further improved the performance of Vortex commitment by 9.6× using GPU. Additionally, Vortex's Open was accelerated by 35.8×. @alexand_belling @zkgbo @YaoGalteland @LineaBuild
