The sequencer delivers 15,000 TPS for stablecoin transfers and up to 43,000 TPS for ETH transfers. The release also enables one-second zero-knowledge (ZK) finality through Airbender, ZKsync’s open-source RISC-V proof system. The Airbender integration produces one-second block proofs and achieves minutes-to-Ethereum finality at a cost of about one-hundredth of a cent per transfer. The new Atlas architecture is modular and supports multiple VM types, positioning ZKsync as the infrastructure connecting private institutional chains with public Ethereum liquidity. Atlas is currently live on testnet, with a mainnet deployment planned in the coming weeks.ICE Invests $2 Billion In PolymarketThe Intercontinental Exchange (ICE), owner of the New York Stock Exchange, announced a strategic investment of up to $2 billion in Polymarket, valuing the company at approximately $8 billion. Under the partnership, ICE will become a global distributor of Polymarket’s event-driven data to institutional investors and collaborate on future tokenization initiatives. Polymarket is the world’s largest prediction market platform with over $14 billion in cumulative volume, enabling users to trade on real-world event outcomes. Polymarket CEO Shayne Coplan called the partnership a major step toward bringing prediction markets into the financial mainstream, adding that the best is yet to come.How Fusaka Changes Node RequirementsethPandaOps, a DevOps group focused on Ethereum’s testing and upgrade infrastructure, outlined how the upcoming Fusaka upgrade will impact node bandwidth and storage demands. The upgrade introduces PeerDAS, a scaling design that allows validators to verify data without downloading entire datasets. PeerDAS breaks the data into small pieces and distributes them across the network based on ETH staked. Under this model, large validators (“supernodes”) manage a heavier data load, while home stakers and non-validating full nodes handle much smaller portions. The approach pushes most of the bandwidth and storage burden onto entities with greater resources, helping keep the network decentralized and accessible to smaller stakers.Wrapped CurrencyCoin Goes LiveCurrencyCoin (CC), a wrapped version of one of the first coins ever deployed on Ethereum, is now live with a liquidity pool on Uniswap. Recognized as a historical artifact, the original CurrencyCoin contract was deployed just 40 days after Ethereum’s Frontier launch and is referenced in the source repository cited by EIP-20. CurrencyCoin has a total supply of 1 trillion tokens. The project has pledged 1% of its supply to the Protocol Guild, 1% to Giveth for causes, and 0.5% to dGen1 Ethereum Phone holders. CurrencyCoin served as a code reference for what became the ERC-20 standard.Other NewsACDT #56 takeawaysFeedback on changes to EthereumFoundry v1.4.0-rc3BNY considers tokenized depositsSharpLink generates 4,723 ETHGitcoin grants siteOpenStableIndex S3 dropETH is money songAave Base hits $2.2b TVLEuler hits $2b in borrowsENS September updatesMaple Finance goes live on LineaWormhole to power SPXA interopPrevious News MetaMask rewards programPrivacy on Ethereum #13Introducing ERC-SArgentina's Crypto Story on 8th OctoberFluid introduces a ReserveRainbow integrates perpsDisclaimer: Content is for informational purposes only, not endorsement or investment advice.
