Papers & Articles
- Cross-Chain Sealed-Bid Auctions Using Confidential Compute Blockchains by Jonas Gebele, Timm Mutzel, Burak Öz, and Florian Matthes present a sealed-bid auction protocol that executes sensitive bidding logic on SUAVE while retaining settlement and enforcement on Ethereum.
- Introducing FlowProxy by Jonas and Lorenzo details FlowProxy as a new implementation of orderflow-proxy built in Rust, with the goal of reducing end-to-end latency and increasing observability in BuilderNet.
- Beyond Flashtestations by Tei Im outlines a framework for extending Flashtestation to support decentralized, untrusted L2 block building with an onchain BuilderHub.
- From Solana to the EVM: A New Path for Proprietary AMMs by @optimus details the advantages of Prop-AMMs, explores why they haven’t gained traction on EVM-chains, and outlines a mechanism to facilitate top-of-block market maker updates.
- Variants of Mempool Tickets by Julian Ma compares different mempool ticketing designs for a vertically sharded blob mempool with reduced bandwidth costs and improved scalability in preparation for PeerDAS.
- Hybrid Encrypted Mempools by Julian Ma and Benedikt Wagner presents a hybrid encrypted mempool design that combines sealed transactions and threshold encryption to mitigate sandwich attacks, enhance privacy, and improve censorship resistance.
- Selecting Optimal Outbound Neighbors (SOON) for fast, bandwidth‑efficient propagation in P2P networks by Thomas Thiery and Marios Ioannou introduces a P2P propagation rule that reduces latency and bandwidth by forwarding messages to the fastest peers instead of random ones, without altering GossipSub’s core design.
- Nonce Bitmap - Enabling Parallel Transaction Submission for a Parallel Blockchain by Thanh Nguyen presents a transaction nonce mechanism that enables up to 256 parallel transactions per account using a bitmap-based design with minimal storage overhead.
- Benchmarking zkVMs for Ethereum by Ignacio Hagopian details how the Ethereum Foundation’s zkEVM team is stress-testing and benchmarking zkVMs to evaluate if they are performant and reliable enough to achieve real-time proving.

- Post by chaskin.eth
- Zkzkevm: private evm by Barry Whitehat outlines a mechanism for compiling Solidity contracts into zkEVM-compatible bytecode that supports private user storage, enabling hybrid privacy structures where user-specific state is hidden but global state remains public.
- Unrealized manipulation attack by Mediabs2022 details six new unrealized manipulation attacks where adversarial proposers, through selective block withholding and multi-epoch coordination, can force reorgs.
- Byzantine takeover attack by Mediabs2022 presents six Byzantine takeover attacks in which ⅓ of validators collude using RANDAO-grinding and delayed block releases to repeatedly reorg the chain.
