• Quantstamp – Evaluating Rollup Compression
  
  • Compression is usually neglected when discussing rollups. By design, rollups are required to make knowledge out there with a view to confirm state transitions or state roots; nonetheless, the tactic for this publication varies, and will embrace compressed knowledge. There’s additionally variability within the compression methods used. This undertaking will discover the usage of compression within the rollup setting. First, the undertaking will explicate locations the place compression is used and doc the methods that could be used. Second, the undertaking will survey present rollups to research the approaches which are truly utilized in observe. Third, the undertaking will consider approaches proposed or used throughout related programs and try and determine why a specific strategy is used. Lastly, the undertaking will use the insights collected with a view to counsel new approaches for compression of rollup knowledge and pose open issues to the neighborhood.

• Diablobench – Efficiency and Safety Analysis of Layer 2 Blockchain Methods
  
  • The College of Sydney and the EPFL have designed a benchmark suite to guage the safety and efficiency of blockchain programs. The primary evaluations in contrast layer 1 blockchains reminiscent of Algorand, Solana and Diem and might be revealed quickly in a peer reviewed worldwide convention (Eurosys). This undertaking goals at including layer 2 blockchain programs to the Diablo benchmark and to make use of it to supply the primary intensive and sensible benchmark analysis of layer 2 blockchain programs on a worldwide deployment.

• Web3-data – Layer 2 Exercise Monitoring & Comparability Suite
  
  • Via this undertaking, we goal to ship a high-quality set of Dashboards that assist allow knowledge scientists, researchers, and all neighborhood members to higher perceive Layer 2 Exercise
  • We are going to mixture knowledge throughout Layer 2 networks leveraging sources reminiscent of Dune, L2Beats, Santiment, CoinGecko, Github, Discord, and, in lots of instances, immediately from the undertaking APIs/RPCs.
  • We are going to clear and set up this knowledge to supply a set of shows that may permit the neighborhood to visualise modifications throughout key L2 metrics (e.g. tps, hire paid to Ethereum, progress in TVL, each day energetic addresses, new addresses, complete addresses, charges paid, and developer exercise primarily based on GitHub affiliated repo commits).
  • We goal to label good contracts (and in the end allow the neighborhood to label good contracts) by utilization classes (Native switch, DeFi DEX, DeFi different, NFT, CEX, Stablecoin, ERC20 different, L2 hire, Bridge, Arbitrage/MEV, Utility). This labeling will permit us to research and visualize the utilization patterns on a excessive degree and likewise present the “hottest” good 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 training.

Knowledge Visualization

• Quantstamp – Again-Finish API Normal for L2 Block Exporers
  
  • This undertaking will clearly outline properties {that a} block explorer ought to implement with a view to be thought-about feature-complete within the common layer two setting. Moreover, our purpose 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 drastically simplify the event of a number of block explorers that may plug-and-play reusable with all of the layer 2 networks that help the usual. Within the best situation, the usual would flip the event of the core of a brand new block explorer right into a undertaking that could possibly be accomplished by an skilled group throughout a weekend hackathon. Our purpose 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 undertaking can pay particular consideration to what distinctive layer two knowledge a block explorer ought to present, with an emphasis on these associated to safety of the chains monitored by it.

• Blossom Labs – Blobscan
  
  • 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 by in a straightforward approach, offering the required 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) at present, Arbitrum and Optimism, attempt to increase present Ethereum consumer software program (Geth) to help interactive fraud proof (IFP) development, 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 consumer program binary—oblivious to its higher-level semantics. This strategy (1) precludes the trust-minimized, permissionless participation of a number of Ethereum consumer applications, magnifying monocolture failure danger; (2) results in an unnecessarily giant 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 subsequently centered on constructing a safe, trust-minimized ORU that addresses these issues, whereas preserving scalability and dispute decision effectivity. To take action, we’ve designed an IFP system native to the EVM, that enforces Ethereum’s semi-formally specified semantics [5] exactly on the degree 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 help IFP development—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 potential than the claimed safety degree asserts.

• Ethstorage – Proof of Storage on L2 Dynamic Datasets with an Ethereum L1 Contract
  
  • Given a listing of commitments of BLOBs (e.g., KZG commitments from EIP-4844/Danksharding, listed from 0…n-1) in an L1 contract, the undertaking is to review 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 sincere, we might construct an L2 storage community that reuses mainnet safety whereas extending Ethereum scalability dramatically.
  • Additional analysis will try and reply the questions of easy methods to construct the proof/verification system if the BLOBs and the commitments are always modified (e.g., new BLOBs are appended to the checklist or a BLOB of an index is modified); and easy methods to construct incentivized/cost system to make sure desired replication issue utilizing ETH as cost; it’s potential to ask a storage node to retailer partial BLOBs whereas sustaining the identical degree of safety of Mainnet?

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