Taiko: a based contestable rollup
Taiko. Taiko Labs.
Taiko proposes that Ethereum proposers, not a separate sequencer, order the rollup, and that a contest can still challenge the execution.
A reading of the project's public design document. Not a copy, not a benchmark, and not an offer.

01 Claim ledger
What the paper is allowed to say
Each row is a sentence already in the study. The status is the same on every row: a model claim, not a live measurement.
Claim 01 · Paper model
The defect
A based rollup that quietly keeps a permissioned proposer has reused the adjective and dropped the mechanism.
Claim 02 · Paper model
The proposal
Taiko proposes that Ethereum proposers, not a separate sequencer, order the rollup, and that a contest can still challenge the execution.
Claim 03 · Paper model
The mechanism
Ordering comes from the settlement chain's proposers. That is the content of 'based'. It is not a claim about fees.
Claim 04 · Paper model
The bound
This note does not say that every Taiko release has based ordering switched on.
02 Three cuts
Observation, model, falsifier
A desk does not stop at the summary. Each claim is cut three ways, using only this study's own assumptions and checks. Nothing here is a new figure.
01 The defect
Observation
What the study says
A based rollup that quietly keeps a permissioned proposer has reused the adjective and dropped the mechanism.
Model
What has to hold
You are reading Taiko's protocol docs. A later parameter change is a different object.
02 The proposal
Observation
What the study says
Taiko proposes that Ethereum proposers, not a separate sequencer, order the rollup, and that a contest can still challenge the execution.
Model
What has to hold
You are reading Taiko's protocol docs. A later parameter change is a different object.
Falsifier
What would retire it
What is the contest about: execution, ordering, or both?
03 The mechanism
Observation
What the study says
Ordering comes from the settlement chain's proposers. That is the content of 'based'. It is not a claim about fees.
Model
What has to hold
No price, supply, yield, or adoption figure is added by this desk.
Falsifier
What would retire it
What is the contest about: execution, ordering, or both?
04 The bound
Observation
What the study says
This note does not say that every Taiko release has based ordering switched on.
Model
What has to hold
You are reading Taiko's protocol docs. A later parameter change is a different object.
Falsifier
What would retire it
Who may propose a Taiko block in the document you are reading?
03 Sequence
One action, as an operating tape
- 01Ordering comes from the settlement chain's proposers. That is the content of 'based'. It is not a claim about fees.
- 02Contestation is how an invalid execution is supposed to lose. If contests are closed, the design you are looking at is not this one.
- 03Based ordering does not remove the need to publish the rollup's data.
04 Load-bearing
The argument, and where a pitch drops it
What the name has to mean
The cut
Taiko proposes that Ethereum proposers, not a separate sequencer, order the rollup, and that a contest can still challenge the execution.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
This note does not say that every Taiko release has based ordering switched on.
What actually moves
The cut
Contestation is how an invalid execution is supposed to lose. If contests are closed, the design you are looking at is not this one.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
A later client, parameter or reward formula is a different object from this paragraph.
What a later deployment may change
The cut
Based ordering does not remove the need to publish the rollup's data.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
This note does not say that every Taiko release has based ordering switched on.
05 Register
What has to be true
Model · Not re-measured
You are reading Taiko's protocol docs. A later parameter change is a different object.
Model · Not re-measured
The document is the one at the source URL. A marketing page with the same brand is not this text.
Model · Not re-measured
No price, supply, yield, or adoption figure is added by this desk.
06 Divergence
What happened after the paper
Inheriting Ethereum's proposer set also inherits that set's censorship properties. It does not improve them by slogan.
A later client, parameter set, or reward formula is a different object. Cite this paper for the mechanism. Cite a primary release for the network. This desk has not re-run the proof.
07 Pre-mortem
What to check before you use the idea
- 0 of 3 marked on this browser. A mark is a reading note, not a pass, a rating, or a recommendation.
08 Anatomy
The paper, in the order a builder needs
The problem it names
A based rollup that quietly keeps a permissioned proposer has reused the adjective and dropped the mechanism.
What the design proposes
- Ordering comes from the settlement chain's proposers. That is the content of 'based'. It is not a claim about fees.
- Contestation is how an invalid execution is supposed to lose. If contests are closed, the design you are looking at is not this one.
- Based ordering does not remove the need to publish the rollup's data.
How the mechanism is specified
- Ordering comes from the settlement chain's proposers. That is the content of 'based'. It is not a claim about fees.
- Contestation is how an invalid execution is supposed to lose. If contests are closed, the design you are looking at is not this one.
- Based ordering does not remove the need to publish the rollup's data.
What this page does not treat as proven
- This note does not say that every Taiko release has based ordering switched on.
- It does not quote a contest bond or a delay.
- Inheriting Ethereum's proposer set also inherits that set's censorship properties. It does not improve them by slogan.
09 Lexicon
Terms, opened into the record
- Based sequencing
- Ordering by the settlement chain's own proposers, rather than by a rollup-run sequencer.
