# Papers & Articles

- [The Geography of (Concurrent) Block Proposing](https://arxiv.org/abs/2610.18812) by [Ciamac C. Moallemi](https://moallemi.com/ciamac/), [Mallesh M. Pai](https://www.malleshmpai.com/), [Dan Robinson](https://x.com/danrobinson), and @Christoph models how multiple concurrent block proposers can encourage geographic decentralization as competing proposers benefit from locating near different information sources and receiving market information before their rivals.
- [Empirical Analysis of TEE-Enabled Rollup Designs](http://arxiv.org/abs/2610.24284v1) by [Claudiu-Nicu Bărbieru](https://arxiv.org/search/cs?searchtype=author&query=B%C4%83rbieru,+C), [Corentin Libert](https://www.linkedin.com/in/corentin-libert/), [Peterson Yuhala](https://www.linkedin.com/in/peterson-yuhala-14009411a/), [Andrei Arusoaie](https://www.linkedin.com/in/andrei-arusoaie/), [Matthieu Bettinger](https://www.linkedin.com/in/matthieu-bettinger-mb/), [Oana-Otilia Captarencu](https://arxiv.org/search/cs?searchtype=author&query=Captarencu,+O), [Pascal Felber](http://members.unine.ch/pascal.felber/index.html), [Emanuel Onica](https://www.linkedin.com/in/emanuel-onica-ab459a3/), [Etienne Rivière](https://www.linkedin.com/in/etienne-riviere-38302b28/), and [Valerio Schiavoni](http://members.unine.ch/valerio.schiavoni/) benchmarks rollup designs using[Flashbots](https://www.flashbots.net/)’[Rollup-Boost](https://github.com/flashbots/rollup-boost), finding minimal inclusion-time overhead from TEEs, and roughly twice as fast inclusion with [op-rbuilder](https://github.com/flashbots/op-rbuilder) versus[op-geth](https://github.com/ethereum-optimism/op-geth).
- [The Dark Forest Was a Testing Ground](https://bwarburg.substack.com/p/the-dark-forest-was-a-testing-ground) by [Bettina Warburg](https://bettinawarburg.com/) draws on [Flashbots](https://www.flashbots.net/)’ research in MEV and adversarial markets to address central questions facing the emerging agent economy around verifiable actions, delegated authority, and _[Proof-of-Control](https://advancedaisociety.org/proof-of-control)_.
  - [Thread](https://x.com/BWarburg/status/2111488420316930329) by [Bettina Warburg](https://bettinawarburg.com/)

- [Loss-versus-rebalancing with external proportional transaction costs](http://arxiv.org/abs/2610.21057v1) by [Masaaki Fukasawa](https://www.linkedin.com/in/masaaki-fukasawa-96819387/) studies AMM liquidity provision, identifying zero-LVR conditions where LPs perform as well as rebalancing after trading costs.
- [How Much Screening Buys a Second? Speed, Selection, and the Maker’s Spread](https://ethresear.ch/t/how-much-screening-buys-a-second-speed-selection-and-the-makers-spread/26158) by [nuconstruct](https://nuconstruct.xyz/) models the trade-off between speed and screening, finding that a twelve-second maker must reject roughly 85% of informed flow to match an unscreened one-second maker’s break-even spread.
- [Active Liquidity On Chain: Evidence from PropAMMs Across Chains](https://x.com/category_xyz/status/2110353567911453130) by [Ozan Solmaz](https://arxiv.org/search/cs?searchtype=author&query=Solmaz,+O), [Lioba Heimbach](https://liobaheimba.ch/), and [Jason Milionis](https://jasonmili.github.io/) summarizes findings from _[Active Liquidity On Chain: Evidence from PropAMMs Across Chains](https://arxiv.org/abs/2609.38056)_, which analyzes how propAMMs achieve better short-term markouts than AMMs, and evaluates the prices they offer retail users.

- [Glamsterdam scaling results on Sepolia, ten days in](https://terencechain.com/writing/glamsterdam-scaling-results-ten-days-in/) by [Terence Tsao](https://x.com/terencechain) reports a 134% higher average gas use per block since Glamsterdam activation on Sepolia, alongside faster median block arrival and lower overall median payload execution time.

- [Derek Chiang](https://x.com/decentrek) published a [post](https://x.com/decentrek/status/2112535053188145367) explaining how[EIP-8288](https://eips.ethereum.org/EIPS/eip-8288) would turn Ethereum’s mempool into a distributed proving network, combining signatures and proofs before a builder produces one final proof with lightweight verification for validators.
