Shared Sequencers

Not ranked right now: four products remain where a ranking needs five.

Too few are left for a fair order, so you get the four that remain, what we read on each, and the questions to judge them by.

We check this again by 25 December 2026.Last checked on 10 November 2026.

To see what we read, what we leave unread and what brings a ranking back, read Why some categories are not ranked right now.

What we track, A to Z

In alphabetical order, not in any order of merit.

  • Espresso Network

    Read in full on 28 October 2026

    On 10 November 2026 it was read again except for one item: whether its own staking front end states a country rule.

  • Rome Protocol

    Read in full on 10 November 2026

    Rome publishes no terms of use. Its privacy policy (rome.builders/privacy, read on 10 November 2026) states: "Bloom is offered only to non-U.S. persons; U.S. residents are not onboarded." The sentence is written for Bloom, its platform for tokenised real-world assets, not for building on Rome.

  • Spire (Based Stack / Pylon)

  • Taiko (Taiko Alethia)

    Read in full on 10 November 2026

    Incident, 21 June 2026: an attacker forged proofs through a debug-mode prover instance and withdrew about USD 1.75 million from Taiko's canonical Bridge and ERC20 vault before both were paused. Taiko says the bridge was recollateralised 1:1, the shortfall was covered by the Foundation and the bridge reopened on 2 July 2026 (Taiko's own post-mortem, read 10 November 2026).

No longer offered

  • AltLayer SQUAD

    Still listed in one line of AltLayer's documentation overview, but its own documentation page is gone and AltLayer's product and updates pages do not name it; no current page describes the product.

  • Radius

    Its own post of 27 August 2026 says it "evolved from block production and MEV resistance to operating solvers and building execution systems"; its homepage names no sequencing product.

Why, in full

We compared six shared sequencers on four things. When we read them all again on 10 November 2026, two were no longer offered as products. Radius says in its own post of 27 August 2026 that it "evolved from block production and MEV resistance to operating solvers and building execution systems". AltLayer SQUAD survives only as one line in AltLayer's documentation overview: its own page is gone, and AltLayer's product and updates pages do not name it. Four remain, each read in the last 45 days (three on 10 November 2026, Espresso Network on 28 October 2026), and a fair order needs at least five. They are listed A to Z with what we read.

Not ranked since 10 November 2026. Last checked on 10 November 2026. What brings the ranking back: A fifth shared sequencer with public documentation can be read and compared, or Radius or AltLayer SQUAD is offered again. Then we read all five and rank them.
