Coordicide: removing the IOTA coordinator
IOTA Coordicide. IOTA Foundation.
Coordicide proposes a consensus for the IOTA tangle that does not depend on a coordinator node. The historic tangle paper is the earlier design. This is the removal plan.
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 coordinator is a permissioned tip selector. Removing it is the entire content of the word coordicide. A network that still has one has not shipped this paper.
Claim 02 · Paper model
The proposal
Coordicide proposes a consensus for the IOTA tangle that does not depend on a coordinator node. The historic tangle paper is the earlier design. This is the removal plan.
Claim 03 · Paper model
The mechanism
Nodes have identities and a voting or mana mechanism the paper specifies, so that sybils do not pick the tips.
Claim 04 · Paper model
The bound
This note does not say the live network has completed the transition.
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.

What the study says
A coordinator is a permissioned tip selector. Removing it is the entire content of the word coordicide. A network that still has one has not shipped this paper.

03 Sequence
One action, as an operating tape
- 01Nodes have identities and a voting or mana mechanism the paper specifies, so that sybils do not pick the tips.
- 02The tangle's DAG structure remains. The consensus on which branch is confirmed is what the paper adds.
- 03Mana, if used as a scarce resource, is a sybil defence. It is not a yield.
04 Load-bearing
The argument, and where a pitch drops it
What the name has to mean
The cut
Coordicide proposes a consensus for the IOTA tangle that does not depend on a coordinator node. The historic tangle paper is the earlier design. This is the removal plan.
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
The historic tangle PDF stays in the old library and is not re-essayed here.
What actually moves
The cut
The tangle's DAG structure remains. The consensus on which branch is confirmed is what the paper adds.
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
The historic tangle PDF stays in the old library and is not re-essayed here.
What a later deployment may change
The cut
Mana, if used as a scarce resource, is a sybil defence. It is not a yield.
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 has to be true
Model · Not re-measured
You are reading the Coordicide paper. The original tangle paper is a different document.
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
No throughput figure is copied.
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.

08 Anatomy
The paper, in the order a builder needs
The problem it names
A coordinator is a permissioned tip selector. Removing it is the entire content of the word coordicide. A network that still has one has not shipped this paper.
What the design proposes
- Nodes have identities and a voting or mana mechanism the paper specifies, so that sybils do not pick the tips.
- The tangle's DAG structure remains. The consensus on which branch is confirmed is what the paper adds.
- Mana, if used as a scarce resource, is a sybil defence. It is not a yield.
How the mechanism is specified
- Nodes have identities and a voting or mana mechanism the paper specifies, so that sybils do not pick the tips.
- The tangle's DAG structure remains. The consensus on which branch is confirmed is what the paper adds.
- Mana, if used as a scarce resource, is a sybil defence. It is not a yield.
What this page does not treat as proven
- This note does not say the live network has completed the transition.
- The historic tangle PDF stays in the old library and is not re-essayed here.
- No throughput figure is copied.
Why the desk still reads it
Coordicide proposes a consensus for the IOTA tangle that does not depend on a coordinator node. The historic tangle paper is the earlier design. This is the removal plan.
09 Lexicon
Terms, opened into the record
- Coordinator
- A privileged node the earlier design used to select tips. This paper's point is to remove it.
- Mana
- A scarce weight the paper uses as a sybil control. It is not a price.
