[ethresear.ch] [Execution Layer Research] Measuring priority fees, positions and transaction classification of Ethereum blocks, July 2025 to October 2026

Quick TEMBRI update: I’ve added an initial PropAMM measurement foundation for Ethereum. It now supports reviewed event/call decoding, deterministic same-block/same-pool update→fill pairing, transaction-index and gas-gap measurements, and explicit unmatched-fill labels. The pipeline retains maker update timestamps where available and produces per-block/pool and builder-signal summaries.

The current scope is limited: only reviewed contract rules are enabled, and a pair proves on-chain receipt order—not off-chain quote freshness or builder receipt time. Next steps are additional venue decoders, golden-block validation, bytecode grouping, and then quote-age/markout work.
This effort is for me to study PropAMMs and how my research on Temporal Liquidity Market (TLM) can be applied to PropAMMs. Stay tuned.
