Storage-optimized replay protection: from hash => bool to packed flag lanes, and can the protocol offer better?
A growing class of protocols needs to persist one tiny fact per event, forever: this nullifier is spent, this nonce is used, this session share is settled. Privacy pools write a nullifier per withdrawal. Unordered nonce schemes (Permit2’s nonceBitmap , EIP-4337-style…

Why searchers and builders like candle auctions (and why it matters for the builder market post-Glamsterdam)
tl;dr Open-bidding with random deadline (candle auctions) and few auction participants can lead to higher bidder profits than sealed-bid auctions. This is already true in a one-shot auction without explicit coordination or collusion. For the Ethereum builder-market…

It's time to scale the trust: EIP-8288 on OP Stack
Summary Rollups scaled by moving execution off the L1, but the authentication part of every transaction still goes to the L1. That makes data the likely bottleneck for L2 scaling in the PQ era, even with more blobs. PQ signatures are far larger than ECDSA, so if every L2 user…

Asset-level spending limits and recovery: should rate limiting live in the asset rather than the account?
Most key-compromise defenses today (smart wallets, ERC-7579 modules, social recovery, EIP-7702 delegation) enforce policy in the account’s code. ERC-8403 continues this: spend limits and unlock times are authorities committed under the account’s root. I’d like to probe a…

ERC draft: Account Authority Lifecycle for STVA
Description: A standard model and interface for the full lifecycle of authority over an account: issuance, activation, attenuation (via Scoped Capabilities), review, suspension, revocation, and recovery. Prevents authority drift (stale owners, modules, or keys that outlive their…

PropAMM fills on Ethereum mainnet and PropAMM support for TEMBRI (toolbox): same-block quotes, a small spread, and flow taken from lagging AMMs
Abstract PropAMMs are on-chain venues whose prices are set by a single maker. The maker pushes quote state on-chain, and fills read that state. We decoded 92,627 fills on nine Ethereum PropAMMs over 30 days (10 September to 9 October 2026) from execution data. We priced the…

ERC draft: Independent Simulation Result for (STVA)
Description: A canonical, content-addressed structure that any independent party (wallet, hardware device, second machine, third-party verifier) can produce and re-verify from the exact same VerificationPayload + state snapshot. It turns simulation from a trusted frontend…

Post-quantum signatureless authorization with recursive verification
Digital signatures control who can spend funds, issue commands and authorize requests. Widely used schemes rely on factoring or discrete logarithms, assumptions threatened by Shor’s quantum algorithm. The post-quantum transition therefore reaches the mechanism used to establish…

Scoped Capability Tokens for STVA
description: Short-lived, purpose-limited, revocable authorization tokens (EIP-712 typed data or ERC-1271-compatible) that grant only specific actions (e.g. upgrade implementation to 0x…transfer X of token Y to Z install module with permissions P). They eliminate ambient…

Secure Transaction Verification and Authorization (STVA)
A standard interface and workflow for verifiable, human-readable transaction simulation, scoped authorization, and independent verification of signing payloads for EOAs, smart accounts, and multisigs. author: @MATOBOYCRYPTO65 discussions-to: (ERC Draft), Secure Transaction…

Ephemeral Rollup: The New "L1.5" of Ethereum
Ephemeral Rollup: The New “L1.5” of Ethereum TLDR; Ethereum’s core job has always been verifying state transitions. While rollups made that verification succinct, they at the same time hold their users’ state, which is why every rollup needs an exit. Native account abstraction (…

Proof of One: one-person-one-identity polling with encrypted ballots — design and reference code, requesting critical review
Hi all, I am Nemo Unus, the pseudonymous maintainer of Proof of One. It is an open-source, non-commercial design for polls with four properties: Every participant is a unique human. Nobody, including operators, can link answers to people. Every voter can verify their own…

Inventory of PQ P2P Migrations in the Consensus Layer
Author: @adust09 from Nyx Foundation Abstract In this post, we will take stock of the challenges facing PQ P2P in the consensus layer. Ethereum consensus-layer networking has no adopted post-quantum migration profile. Replacing validator BLS signatures with leanXMSS does not…

Lean verification of EIP-7002: system-call success and FIFO requests
Since Prague, execution-layer requests for validator exits and partial withdrawals go through a 504-byte contract at 0x00000961Ef480Eb55e80D19ad83579A64c007002 , hand-written for the geas assembler. At the end of every block the protocol makes a system call to it, and that call…

A hash-only rollup: OP Stack L2 accounts as Lamport-style hash chains, no ECDSA inside the L2
Disclosure: I’m the founder of bb84, the payments app that runs on this chain. Feedback, especially critical feedback, is very welcome. TL;DR We run an OP Stack rollup on Ethereum mainnet (chain ID 42069000, live since 2026-09-30) where L2 transactions carry no signatures at all…

Paranoid EIP-8288: heterogeneous recursion with an authenticated class bank
EIP-8288 proposes recursive aggregation under a fixed protocol-level verification key. One backend choice worth exploring is whether recursive steps should support several approved proof sizes, so that small aggregates can use a smaller proving relation. I implemented this kind…

Reveal optionality in encrypted mempools: how big is the sender’s free option, and a post-quantum way to remove it
Hi all, Thanks to @aelowsson @julian @b-wagn @GottfriedHerold , since this builds directly on LUCID, the criticism thread and the ticket-first threshold IBE design. Also a kind request for review on this work. I’ve been wondering how much the “free option” in encrypted mempools…

SEACAST: fast, lean, sampled broadcast for Ethereum, with an executable spec and a formal model
This post follows Informed Diffusion: making home builders publish fast (2026). Author: @cskiraly Update, 29 October 2026: this post stays as published. Its text is kept current, with the latest results, on notes.ethereum.org , and each version, with its data and scripts, at…

Faster, Aggregatable and Quantum Safe Privacy Pools
In collaboration with @winderica TLDR: we port Tornado Cash to Flock, a post-quantum binary-field SNARK, proving a depth-32 withdrawal over SHA-256 in under 30 ms, and describe a simple recovery protocol, requiring only that wallets derive note secrets from a seed, that lets…
