## Content

This weekly blog translates the latest developments, proposals, and research from the Ethereum ecosystem into plain English, so non-technical readers can follow where the network is headed and why it matters. 📰 Headlines Blob Fees Are Getting SmarterSpeculative Bots Are Crowding L2sGas Is Going Multi-DimensionalThe Blobpool Needs a RedesignBerlinterop Accelerates Fusaka🚦 BLOB_BASE_COST: Making Blob Fees SmarterEthereum’s new blob data format (introduced via EIP-4844) was designed to help Layer 2s scale more efficiently. But blob fees are currently too reactive: they can drop to near-zero when demand is low, and take hours to rise again when traffic picks up. What’s changing? The BLOB_BASE_COST proposal sets a minimum blob fee based on the execution cost of the transaction. That way, blob space isn’t underpriced, and network resources are more fairly used. Why it matters:Faster recovery from congestionMore stable pricingFairer cost coverage for node operators🗓 Timeline: Included in Fusaka Devnet 2 launching June 23, 2025 Expected on mainnet in late 2025 with the Fusaka hard fork📈 Optimistic MEV in Layer 2s: A Hidden Force Crowding BlocksA new paper reveals that over 50% of gas on Base and Optimism is used by speculative arbitrage bots engaging in “optimistic MEV.” These bots blindly send trades hoping to make a profit—even if most attempts fail. Why it’s a problem:Fills blockspace with failed tradesCrowds out regular usersBots pay relatively little in feesSolutions being explored:Fee model changes (e.g. charging more for reverted trades)Private or encrypted mempoolsSequencer-level filteringShared sequencing and block auctionsMEV redistribution models (like MEV Burn)In practice: Arbitrum’s private mempool already helps reduce MEV spam More L2s are tweaking gas pricing and transaction inclusion logic⚙ Going Multidimensional: Gas Metering Gets SmarterToday, Ethereum bundles all resource usage—computation, storage, bandwidth—into one “gas” number. That’s not very efficient. This research proposes multi-dimensional gas metering, where each resource gets its own gas limit and fee market. Benefits:Fairer pricingBetter network throughputGreater security marginsRoadmap Highlights:Now – 2025: New opcodes (like EVM-384) to better reflect resource use2025–2026: Expand to 2D or 3D gas models (e.g. separate fees for execution, calldata, blobs)Post-2026: Redesign EVM to fully support resource-specific pricing and limits💬 The Future of the Blob MempoolEthereum’s blob mempool (a waiting area for blob-carrying transactions) currently gossips entire blobs—which is becoming unsustainable as blob counts increase. Proposal:Implement a vertically sharded blobpool, where nodes only share the columns of blob data they’re responsible for verifyingAdd a ticket or deposit system to prevent spam by requiring “blobspace rights” to submit blobsTimeline: June 2025 (Fusaka): PeerDAS goes live, but blobpool remains full-blob Late 2025 (Glamsterdam): Vertically sharded blobpool + auction system expected🧪 Checkpoint #4 – BerlinteropThe Berlinterop workshop (held during Berlin Blockchain Week) brought devs and researchers together to push forward key Ethereum upgrades. Here’s what happened: 🔥 Short-term:Fusaka Devnet 2 launched, with plans to release a final Sepolia testnet by late summer 2025Gas limit increases (to ~45M per block) finalized and soon to roll outFast-tracking client implementation readiness🔮 Long-term:Slot restructuring: shorter slot durations for faster confirmationsHistory expiry: dropping old pre-Merge history to lighten nodesConsensus hardening: 26 resilience goals identifiedL2 & zk collaboration: roadmap includes more blobs, faster finality, and standardized syscalls🧵 TL;DR Upgrade AreaWhat’s ChangingWhenBlob FeesIntroduce BLOB_BASE_COST minimumFusaka (Q3 2025)MEV SpamFee tweaks, mempool filters, PBSOngoing in L2sGas MeteringMulti-dimensional pricing2025–2026+Blobpool DesignVertical sharding + ticket systemGlamsterdam (Late 2025)Berlinterop DevnetsFusaka devnets, gas increase, testnet prepSummer 2025📬 For More Updates Like TheseSubscribe to Ethereum Daily on ParagraphFollow @Rue1776 on Twitter and @ethereumdaily.eth on Farcaster
