The primary evaluations in contrast layer 1 blockchains equivalent to Algorand, Solana and Diem and might be printed quickly in a peer reviewed worldwide convention (Eurosys). This mission goals at including layer 2 blockchain programs to the Diablo benchmark and to make use of it to provide the primary in depth and reasonable benchmark analysis of layer 2 blockchain programs on a worldwide deployment.

  • Web3-data – Layer 2 Exercise Monitoring & Comparability Suite

    • By means of this mission, we goal to ship a high-quality set of Dashboards that assist allow information scientists, researchers, and all neighborhood members to raised perceive Layer 2 Exercise
    • We are going to mixture information throughout Layer 2 networks leveraging sources equivalent to Dune, L2Beats, Santiment, CoinGecko, Github, Discord, and, in lots of instances, straight from the mission APIs/RPCs.
    • We are going to clear and manage this information to supply a set of shows that can permit the neighborhood to visualise modifications throughout key L2 metrics (e.g. tps, lease paid to Ethereum, progress in TVL, every day lively addresses, new addresses, whole addresses, charges paid, and developer exercise based mostly on GitHub affiliated repo commits).
    • We goal to label sensible contracts (and in the end allow the neighborhood to label sensible contracts) by utilization classes (Native switch, DeFi DEX, DeFi different, NFT, CEX, Stablecoin, ERC20 different, L2 lease, Bridge, Arbitrage/MEV, Utility). This labeling will permit us to research and visualize the utilization patterns on a excessive stage and in addition present the “hottest” sensible contracts within the completely different utilization classes. We’re leveraging recognized labels from Dune, Arbiscan, Etherscan, and others.

  • L2 Beat – L2 Beat

    • Proceed to work on clear and verifiable insights into rising layer two (L2) applied sciences with expanded metrics and schooling.

đź“Š Knowledge Visualization

  • Quantstamp – Again-Finish API Normal for L2 Block Exporers

    • This mission will clearly outline properties {that a} block explorer ought to implement so as to be thought-about feature-complete within the common layer two setting. Moreover, our aim is to suggest and specify a typical API interface that the layer two networks ought to expose to common block explorers. We envision that such a standardized interface will allow and vastly simplify the event of a number of block explorers that can plug-and-play reusable with all of the layer 2 networks that assist the usual. Within the preferrred state of affairs, the usual would flip the event of the core of a brand new block explorer right into a mission that could possibly be accomplished by an skilled crew throughout a weekend hackathon. Our aim might be to additionally outline a typical that’s consumer-agnostic. As such, it is not going to matter whether or not it’s consumed by a block explorer that’s supplied commercially, is open supply, or doubtlessly even decentralized. The mission can pay particular consideration to what distinctive layer two information a block explorer ought to present, with an emphasis on these associated to safety of the chains monitored by it.

  • Blossom LabsBlobscan

    • The primary explorer for the EIP-4844 shard blob transactions. It indexes and presents them in a searchable format that the person can visualize and navigate via in a straightforward manner, offering the mandatory infrastructure to scale Ethereum.

🧮 Cryptography and Zero-knowledge proofs

  • Zhe Ye, Ujval Misra, and Daybreak Tune (College of California at Berkeley) – Specular

    • The preferred optimistic rollups (ORUs) in the present day, Arbitrum and Optimism, attempt to increase current Ethereum shopper software program (Geth) to assist interactive fraud proof (IFP) building, aiming to reuse prior L1 engineering efforts and replicate EVM semantics at L2. Sadly, to take action they tightly couple their on-chain IFP verifier with a selected shopper program binary—oblivious to its higher-level semantics. This strategy (1) precludes the trust-minimized, permissionless participation of a number of Ethereum shopper applications, magnifying monocolture failure threat; (2) results in an unnecessarily massive and sophisticated trusted computing base (TCB) that’s troublesome to independently audit; and, (3) suffers from a frequently-triggered, but opaque improve course of—each additional growing auditing overhead, and complicating on-chain entry management within the long-term.
    • We’re due to this fact targeted on constructing a safe, trust-minimized ORU that addresses these issues, whereas preserving scalability and dispute decision effectivity. To take action, we have now designed an IFP system native to the EVM, that enforces Ethereum’s semi-formally specified semantics [5] exactly on the stage of a single EVM instruction. As part of this work, we constructed Specular, an ORU which leverages Geth—modified minimally with solely 99 lines-of-code to assist IFP building—demonstrating the practicality, extensibility and trust-minimal nature of our strategy.

  • Nethermind, Justin Thaler (Georgetown College), Matthew Inexperienced (Johns Hopkins College), and Pratyush Tiwari (Georgetown College) – Concrete Safety Evaluation for L2 Deployed Proof Methods

    • We suggest to research the concrete safety of the proof programs (SNARKs, STARKs) that safe -rollups. We observe that some proof programs have safety analyzed within the interactive setting, whereas their safety after making use of the Fiat—Shamir transformation is barely conjectured. Moreover, we imagine that in some instances extra environment friendly assaults are attainable than the claimed safety stage asserts.

  • Ethstorage – Proof of Storage on L2 Dynamic Datasets with an Ethereum L1 Contract

    • Given an inventory of commitments of BLOBs (e.g., KZG commitments from EIP-4844/Danksharding, listed from 0…n-1) in an L1 contract, the mission is to check an environment friendly proof system to effectively confirm on L1 that the BLOBs are saved off-chain with the specified redundancy (e.g., 30~50 bodily replicas). By placing these storage nodes in an L2 community and assuming 1/m of nodes is trustworthy, we may construct an L2 storage community that reuses mainnet safety whereas extending Ethereum scalability dramatically.
    • Additional analysis will try to reply the questions of how one can construct the proof/verification system if the BLOBs and the commitments are continually modified (e.g., new BLOBs are appended to the record or a BLOB of an index is modified); and how one can construct incentivized/cost system to make sure desired replication issue utilizing ETH as cost; it’s attainable to ask a storage node to retailer partial BLOBs whereas sustaining the identical stage of safety of Mainnet?

We have been extraordinarily pleased with the standard of candidates for this grants spherical. The analysis and work they produce can have a optimistic affect on the ecosystem. We advise keeping track of them!
