It permits development a brand new elegance of packages that may have extra freedom over their execution possible choices.

  • ScopeLift – L2 Optimizors

    • Layer 2 networks proportion safety with main-net by way of posting transaction name records to Layer 1. In consequence, Layer 2 customers pay their portion of the main-net gasoline prices when executing transactions. Layer 1 gasoline will also be >25,000x dearer than Layer 2 gasoline, so paying for name records dominates L2 transaction prices. With customized router contracts that use much less name records than usual strategies, we will considerably cut back transaction prices to engage with widespread protocols.

  • Testinprod – Layer1.5

    • Layer 1.5 permits any individual to release their very own Layer 2 by way of offering simple equipment. It supplies a very easy software that launches your individual Layer 2 with essential equipment—as an example, block explorer, token bridge, tracking equipment, and many others.

  • Bruce Xu – MyFirstLayer2

    • This will likely be an open-source, community-driven, and academic challenge. This will likely be a web page for folks excited by Layer2 however with out prior information about Layer2 or Blockchain. We goal to make use of well-designed diagrams and interactive animation to lend a hand folks get the theory at the back of Layer2 in 30mins. Later on, we will be able to information folks to a couple real-world Layer2 apps step by step and allow them to really feel the advantages of Layer2.

🗄️ Knowledge Research

  • Blockscout – Blockscout Block Explorer

    • An open-source block explorer is recently wanted for the L2 ecosystem. Blockscout is already utilized by many L2 initiatives, and further customizations particular to L2 records necessities will building up usability. As well as, a brand new interface, options, analytics and developer pleasant enhancements will lend a hand create a extra clear and usable network explorer.

  • Quantstamp – Comparing Rollup Compression

    • Compression is incessantly lost sight of when discussing rollups. By way of design, rollups are required to make records to be had so as to check state transitions or state roots; then again, the process for this e-newsletter varies, and might come with compressed records. There could also be variability within the compression ways used. This challenge will discover the usage of compression within the rollup atmosphere. First, the challenge will explicate puts the place compression is used and report the ways that can be used. 2nd, the challenge will survey current rollups to research the approaches which are in fact utilized in apply. 3rd, the challenge will review approaches proposed or used throughout an identical techniques and try to determine why a selected manner is used. In spite of everything, the challenge will use the insights accumulated so as to counsel new approaches for compression of rollup records and pose open issues to the network.

  • Diablobench – Efficiency and Safety Analysis of Layer 2 Blockchain Programs

    • The College of Sydney and the EPFL have designed a benchmark suite to judge the safety and function of blockchain techniques. The primary opinions in comparison layer 1 blockchains reminiscent of Algorand, Solana and Diem and will likely be revealed quickly in a peer reviewed world convention (Eurosys). This challenge targets at including layer 2 blockchain techniques to the Diablo benchmark and to make use of it to provide the primary intensive and reasonable benchmark analysis of layer 2 blockchain techniques on a global deployment.

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

    • Thru this challenge, we goal to ship a fine quality set of Dashboards that lend a hand allow records scientists, researchers, and all network contributors to higher perceive Layer 2 Job
    • We will be able to mixture records throughout Layer 2 networks leveraging resources reminiscent of Dune, L2Beats, Santiment, CoinGecko, Github, Discord, and, in lots of circumstances, immediately from the challenge APIs/RPCs.
    • We will be able to blank and arrange this information to supply a collection of presentations that may permit the network to visualise adjustments throughout key L2 metrics (e.g. tps, hire paid to Ethereum, expansion in TVL, day by day energetic addresses, new addresses, general addresses, charges paid, and developer task in keeping with GitHub affiliated repo commits).
    • We goal to label sensible contracts (and in the long run allow the network to label sensible contracts) by way of utilization classes (Local switch, DeFi DEX, DeFi different, NFT, CEX, Stablecoin, ERC20 different, L2 hire, Bridge, Arbitrage/MEV, Software). This labeling will permit us to investigate and visualize the utilization patterns on a excessive point and in addition display the “freshest” sensible contracts within the other utilization classes. We’re leveraging identified labels from Dune, Arbiscan, Etherscan, and others.

  • L2 Beat – L2 Beat

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

📊 Knowledge Visualization

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

    • This challenge will obviously outline houses {that a} block explorer must put in force so as to be thought to be feature-complete within the overall layer two atmosphere. Moreover, our purpose is to suggest and specify a normal API interface that the layer two networks must divulge to overall block explorers. We envision that any such standardized interface will allow and a great deal simplify the advance of a couple of block explorers that may plug-and-play reusable with the entire layer 2 networks that make stronger the usual. Within the preferrred situation, the usual would flip the advance of the core of a brand new block explorer right into a challenge that may be finished by way of an skilled workforce all through a weekend hackathon. Our purpose will likely be to additionally outline a normal this is consumer-agnostic. As such, it’ll no longer subject if it is ate up by way of a block explorer this is supplied commercially, is open supply, or probably even decentralized. The challenge can pay particular consideration to what distinctive layer two records a block explorer must supply, with an emphasis on the ones associated with safety of the chains monitored by way of it.

  • Blossom LabsBlobscan

    • The primary explorer for the EIP-4844 shard blob transactions. It indexes and gifts them in a searchable structure that the person can visualize and navigate thru in a very easy manner, offering the essential infrastructure to scale Ethereum.

🧮 Cryptography and 0-knowledge proofs

  • Zhe Ye, Ujval Misra, and Crack of dawn Music (College of California at Berkeley) – Specular

    • The preferred positive rollups (ORUs) as of late, Arbitrum and Optimism, try to increase current Ethereum consumer device (Geth) to make stronger interactive fraud evidence (IFP) building, aiming to reuse prior L1 engineering efforts and reflect EVM semantics at L2. Sadly, to take action they tightly couple their on-chain IFP verifier with a selected consumer program binary—oblivious to its higher-level semantics. This manner (1) precludes the trust-minimized, permissionless participation of a couple of Ethereum consumer techniques, magnifying monocolture failure chance; (2) ends up in an unnecessarily huge and sophisticated relied on computing base (TCB) this is tricky to independently audit; and, (3) suffers from a frequently-triggered, but opaque improve procedure—each additional expanding auditing overhead, and complicating on-chain get admission to keep an eye on within the long-term.
    • We’re subsequently thinking about development a safe, trust-minimized ORU that addresses those issues, whilst maintaining scalability and dispute solution potency. To take action, we have now designed an IFP device local to the EVM, that enforces Ethereum’s semi-formally specified semantics [5] exactly on the point of a unmarried EVM instruction. As part of this paintings, we constructed Specular, an ORU which leverages Geth—changed minimally with most effective 99 lines-of-code to make stronger IFP building—demonstrating the practicality, extensibility and trust-minimal nature of our manner.

  • Nethermind, Justin Thaler (Georgetown College), Matthew Inexperienced (Johns Hopkins College), and Pratyush Tiwari (Georgetown College) – Concrete Safety Research for L2 Deployed Evidence Programs

    • We recommend to investigate the concrete safety of the evidence techniques (SNARKs, STARKs) that safe -rollups. We follow that some evidence techniques have safety analyzed within the interactive atmosphere, whilst their safety after making use of the Fiat—Shamir transformation is most effective conjectured. Moreover, we consider that during some circumstances extra environment friendly assaults are conceivable than the claimed safety point asserts.

  • Ethstorage – Evidence of Garage 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 challenge is to review an effective evidence device to successfully check on L1 that the BLOBs are saved off-chain with the required redundancy (e.g., 30~50 bodily replicas). By way of hanging those garage nodes in an L2 community and assuming 1/m of nodes is fair, lets construct an L2 garage community that reuses mainnet safety whilst extending Ethereum scalability dramatically.
    • Additional analysis will try to reply to the questions of construct the evidence/verification device if the BLOBs and the commitments are repeatedly modified (e.g., new BLOBs are appended to the record or a BLOB of an index is modified); and construct incentivized/fee device to make sure desired replication issue the usage of ETH as fee; it’s conceivable to invite a garage node to retailer partial BLOBs whilst keeping up the similar point of safety of Mainnet?

We have been extraordinarily proud of the standard of candidates for this grants spherical. The analysis and paintings they produce can have a favorable affect at the ecosystem. We recommend keeping track of them!
