Episode Summary
Executive Summary: Jesse Pollock explains how Ethereum’s Dencun upgrade and proto-dank sharding materially lower Layer 2 costs by introducing blob space, boosting Base and other rollups while setting up a long-term scaling path. He also defends Ethereum’s rollup-centric strategy, highlights decentralization/interoperability progress, and argues that smart wallets and the term “on-chain” are key to mainstream adoption.
Main Topics: Dencun upgrade and blob space (Priority: 5/5): Pollock describes EIP-4844/proto-dank sharding as Ethereum’s first major step toward cheaper Layer 2 scaling via temporary blob storage that acts like a dedicated data lane for rollups. Fee reductions and demand on Base (Priority: 5/5): He reports dramatic fee drops and a surge in activity on Base after Dencun, including sub-cent transactions at times and a sharp increase in TPS as users take advantage of lower costs. Ethereum scaling strategy: L1 settlement, L2 execution, L3 apps (Priority: 5/5): Pollock outlines a modular future where Ethereum L1 mainly handles settlement, L2s handle everyday user transactions, and L3s become application-specific servers deeply tied to on-chain assets and identity. Critiques of rollup-centric scaling (Priority: 4/5): He responds to concerns about fragmentation and centralization by arguing that Ethereum’s open, modular approach attracts more builders, improves throughput, and can still achieve stronger decentralization over time. Interoperability and the superchain vision (Priority: 4/5): Pollock says Base’s use of the OP Stack supports a superchain model where chains increasingly feel like one chain, with ongoing work on security councils, sequencing, and cross-chain proof systems. Developer-enabling EIPs and new use cases (Priority: 4/5): He highlights transient storage (EIP-1153) and EIP-4788 as upgrades that unlock new DeFi, composability, and cross-L1/L2 application designs, especially for Uniswap v4 and inter-chain logic. Smart wallets and the shift to 'on-chain' (Priority: 4/5): Pollock argues that smart wallets are essential for onboarding the next billion users, and that 'on-chain' is a better, less speculative framing than 'crypto' or 'Web3' for mainstream adoption.
Key Arguments: Dencun solves Ethereum scaling by lowering Layer 2 data availability costs through blob space, enabling cheaper rollup transactions without forcing all computation onto L1. Rollups benefit from a separate blob pricing market, which should make fees more stable and less sensitive to congestion on Ethereum L1. Base is already seeing induced demand: lower fees are driving more transactions, more bridging, and broader user activity such as USDC transfers, NFT mints, and trading. Ethereum’s rollup-centric strategy is presented as a decentralization-friendly, collaborative model that has increased developer participation and ecosystem velocity. The main remaining challenges are decentralization and interoperability, but Pollock argues both are advancing quickly via stage-one/stage-two decentralization plans and superchain tooling. EIP-1153 and EIP-4788 expand what developers can build by enabling transient coordination within blocks and cheaper references between L1 and L2 state. Smart wallets are positioned as a prerequisite for mainstream adoption because they reduce setup friction, support gasless UX, and offer bank-like security. The term 'on-chain' is framed as a more accessible, technology-first narrative that replaces speculative associations with a broader story about upgrading financial and digital infrastructure.
Data Points: TPS increase on Base after Dencun: ~5x higher than before the fork - Pollock says Base transaction volume has already risen substantially as lower fees encourage more use. Average fee on Base after Dencun: $0.01 to $0.03 - He cites current average fees after the upgrade, noting they remain much cheaper than before. Estimated fee reduction on Base: 10x to 20x reduction - Based on current average fees compared with pre-fork levels. Peak fee reduction observed: 500x to 1,000x reduction - Pollock says some moments saw sub-cent transactions and extreme fee drops shortly after launch. Dencun activation date: March 13, 2024 (Wednesday before interview) - The upgrade had just gone live on Ethereum mainnet. EIP number: EIP-4844 - Proto-dank sharding / blobs implementation. Blob cost share: 90% to 95% of Layer 2 costs - Pollock says data availability previously dominated L2 costs. Median fees on day one after upgrade (Optimism): $0.05 - Reported in the news recap as one of the biggest fee drops. Median fees on day one after upgrade (Base): $0.064 - Reported in the news recap. Median fees on day one after upgrade (Arbitrum): $0.50 - Reported in the news recap. Median fees on day one after upgrade (zkSync Era): $0.16 - Reported in the news recap. Base funding support for smart wallets: Up to 5 ETH in gas credits - Pollock says Base is funding account abstraction builders to lower experimentation costs. Stage one decentralization target: This year - Pollock says Base expects to become a stage-one decentralized rollup in 2024. Uniswap v4 enabling EIP: EIP-1153 - Transient storage unlocks new Uniswap v4 design possibilities and hooks. Cross-layer reference EIP: EIP-4788 - Lets L2s reference L1 data more cheaply and vice versa, expanding composability.
Pivotal Quotes: "What if instead of just trying to scale layer one, we said, Hey, let's invest all of our efforts in scaling layer two" — Jesse Pollock: Explaining Ethereum’s strategic pivot toward rollup-centric scaling. "think about as an HOV or Carpool lane on Ethereum" — Jesse Pollock: Describing blob space and why it lowers rollup fees. "the job's not finished" — Jesse Pollock: Base’s internal mantra after Dencun, emphasizing that scaling work continues.
Implications: Ethereum is shifting toward a modular economy where L1 secures and settles, L2s serve users, and L3s power applications. Lower fees, better UX, and smart wallets could accelerate mainstream adoption, but interoperability and decentralization remain the key execution tests.
