🧮 Cryptography and Zero-knowledge proofs

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

    • The most well-liked optimistic rollups (ORUs) at present, Arbitrum and Optimism, attempt to increase present Ethereum consumer software program (Geth) to assist 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 tough 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 centered on constructing a safe, trust-minimized ORU that addresses these issues, whereas preserving scalability and dispute decision effectivity. To take action, now we have 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 assist IFP development—demonstrating the practicality, extensibility and trust-minimal nature of our strategy.

We observe that some proof techniques have safety analyzed within the interactive setting, whereas their safety after making use of the Fiat—Shamir transformation is simply conjectured. Moreover, we consider 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 venture 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 sincere, we might 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 always modified (e.g., new BLOBs are appended to the checklist 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 potential to ask a storage node to retailer partial BLOBs whereas sustaining the identical degree of safety of Mainnet?

We had been extraordinarily proud of the standard of candidates for this grants spherical. The analysis and work they produce could have a constructive affect on the ecosystem. We recommend maintaining a tally of them!
