Airbender: the good, the bad, the ugly the good → fastest zkVM™: 14.5 MHz with recursion on a single 5090 🤯 To our knowledge the fastest RISC-V zkVM to date, even without ZisK-style execution. 10kW real-time proving from home soon™. → max GPU squeeze: Hits ~100% GPU utilisation. Props to CUDA wizards @robik and @MichaelCarilli. → permissive GPU prover: The multi-GPU prover is dual-licensed MIT/Apache 2.0. Joins RISC Zero and ZisK in setting the open standard. → EVM client optimisations: Significantly diverges from revm/reth, eg with zk-native handling of interger arithmetic. → Porter: Legendary @portport255, who reads every line of zkVMs, is part of the team. → naming: Orginates from AIR—memorable and playful. the bad → security target: Currently 81 bits (under a proximity gaps conjecture). For scale: Bitcoin hits 2^86 hashes daily. 100 bits is table stakes. ZisK hits 128 bits—the gold standard. Airbender v2 (Q4) will offer customisable security. → no L1 proving (yet): Benchmarked on zkSync (Blake2S binary tree), not Ethereum mainnet (Keccak hexary PMT). Keccak precompile expected this month—then comes Ethproofs. Props to zkSync for exploring zk-friendly trees—mainnet will follow. → H100 benchmarks: Early numbers used datacenter H100s. Retail 5090s are faster, cheaper, more power efficient. The team got the memo—expect more 5090/4090 numbers. → audits: Code is complex, unaudited, and not yet production-ready. the ugly Nothing fundamentally ugly—all the "bad" gets fixed this year :)

Apps, product launches, acquisitions and more… Here are 28 things the Ethereum ecosystem got done over the last few weeks. 0/ @Shopify announced support for stablecoins on @base across their platform, giving millions of businesses in 175+ countries access to Ethereum-powered commerce. 1/ @fileverse launched dSheets, spreadsheets that can natively talk to and interact with smart contracts on Ethereum. dSheets lets teams pull data directly from Ethereum accounts and apps, run complex operations, and collaborate securely 🔐. 2/ Earnifi is a fintech app that makes it easy for anyone to get access to credit, and it’s now the #3 finance app in the US App Store. Powered by @OpacityNetwork and @eigencloud. Ethereum is for apps. 3/ Onchain social network @zora is now the 91st most popular social app in the US App Store. Ethereum is for creators earning onchain. 4/ @rstormf launched a new fundraiser to help pay costs for his upcoming trial in July. The @ethereumfndn donated $500K and is matching another $750K. Privacy is normal, and writing code is not a crime. 5/ @shibuyafilm launched a crowdfunding platform for creators, where 5 filmmakers funded their work by minting individual frames of each episode. The ability to mint has ended but donations on the main website are still open. Ethereum is for culture. 6/ Decentralized exchanges (DEXs) built on Ethereum continue to grow their influence: recently, 25% of spot trades on centralized exchanges originated from DEXs, an all-time high. 7/ @Etherealize_io published “The Bull Case for ETH”, a new report aimed at institutional investors advocating for ETH as a globally significant asset. Ethereum is for ETH. 8/ @eigencloud introduced EigenCloud, a developer platform extending Ethereum-backed trust & verifiability to any app, on or offchain. 9/ @noicedotso launched on @farcaster_xyz, enabling likes, replies and DMs to translate to monetary value. In 6 weeks the team saw 1.6M+ tips worth $91K+. Ethereum is for microtransactions. 10/ @ethereumfndn announced a reorg of their protocol R&D efforts, with a near term focus on three strategic goals: scale L1, scale blobs for L2s, and improve UX. 11/ @sharplink announced a $425M private placement for an Ethereum treasury strategy, led by @Consensys, with plans to purchase ETH as its primary treasury reserve asset. 12/ @jpmorgan announced plans to create JPMD, a USD deposit token for institutional clients to move funds on @base. Ethereum is for institutions. 13/ @zkemail announced a new Registry tool enabling more powerful zero-knowledge features, which will help anyone who wants to selectively disclose private info or verify financial information. 14/ @Uniswap v4 surpassed $84B in swap volume ~5 months after launch. 15/ Automated market maker (AMM), @EkuboProtocol crossed $1B+ in cumulative trading volume. 16/ @stripe acquired @privy_io, a web3 wallet infrastructure company, bringing crypto & fiat closer together to change how value moves through the Internet. 17/ The BUIDL fund paid out $10M+ in dividends on Ethereum in May, the highest monthly total to date. Launched on @Securitize, secured by Ethereum. 18/ Popular lending app, @eulerfinance grew deposits to $2.28B in 3 months and active loans to ~$1.1B, an all-time high. 19/ @AgoraGovernance shipped gasless DAO voting and social vote sharing to make the DAO experience more social and economical. Ethereum is for DAOs. 20/ @MorphoLabs, powering onchain lending, announced “Morpho V2”, a platform designed to meet the needs of DeFi’s sophisticated & institutional participants. Ethereum is for DeFi. 21/ @zksync introduced Prividium, an enterprise-grade blockchain platform for finance. The first institutional partner, @DeutscheBank, is already building on the platform with @Memento_Bc. 22/ @Scroll_ZKP, a zkEVM rollup, achieved a 1-second block time, making the network 3x faster. 23/ Timeboost, a mechanism allowing MEV searchers to bid for priority transaction inclusion on @arbitrum, collected $1.8M in total fees after only 10 weeks of being live. 24/ @StarkWareLtd launched next-gen prover, S-two, enabling client-side proving for everyday devices. 25/ Ethereum Smart Account usage surged. Safe accounts processed 28M transactions in May, 40% more than the previous all-time high. 26/ The ecosystem gathered in Czechia for @ETHPrague and @ETHGlobal Prague, where a combined 600+ hackers and 1000+ attendees came together to learn and build on Ethereum. 27/ @EdgeEsmeralda, a month-long popup village by Esme Institute & @joinedgecity, convened in California. The event brought together people at the frontiers of tech, science, and social innovation, and created an environment where new ideas & systems—like those built on Ethereum—come to life.
