Kaspa: a blockDAG that orders blocks with GHOSTDAG

Kaspa. Kaspa.

Kaspa implements a blockDAG ordered by GHOSTDAG, the PHANTOM line of research, so blocks that are not on a single chain can still be partially ordered.

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.

  1. Claim 01 · Paper model

    The defect

    The PHANTOM paper is the research text already in this library. Kaspa is a network with parameters. Do not cite one as the other.

  2. Claim 02 · Paper model

    The proposal

    Kaspa implements a blockDAG ordered by GHOSTDAG, the PHANTOM line of research, so blocks that are not on a single chain can still be partially ordered.

  3. Claim 03 · Paper model

    The mechanism

    Blocks reference multiple parents. The ordering rule decides which blocks are in the blue set, in the language of the research, and which are treated as red.

  4. Claim 04 · Paper model

    The bound

    This note does not quote a block rate as a performance promise.

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.

  1. 01 The defect

    Observation

    What the study says

    The PHANTOM paper is the research text already in this library. Kaspa is a network with parameters. Do not cite one as the other.

    Model

    What has to hold

    You are reading Kaspa's public materials as an implementation of the PHANTOM/GHOSTDAG line. The paper itself is the other study.

    Falsifier

    What would retire it

    Which paper does the implementation say it follows?

  2. 02 The proposal

    Observation

    What the study says

    Kaspa implements a blockDAG ordered by GHOSTDAG, the PHANTOM line of research, so blocks that are not on a single chain can still be partially ordered.

    Model

    What has to hold

    You are reading Kaspa's public materials as an implementation of the PHANTOM/GHOSTDAG line. The paper itself is the other study.

    Falsifier

    What would retire it

    What confirmation rule does a wallet wait for?

  3. 03 The mechanism

    Observation

    What the study says

    Blocks reference multiple parents. The ordering rule decides which blocks are in the blue set, in the language of the research, and which are treated as red.

    Model

    What has to hold

    No price, supply, yield, or adoption figure is added by this desk.

    Falsifier

    What would retire it

    Which paper does the implementation say it follows?

  4. 04 The bound

    Observation

    What the study says

    This note does not quote a block rate as a performance promise.

03 Sequence

One action, as an operating tape

  1. 01Blocks reference multiple parents. The ordering rule decides which blocks are in the blue set, in the language of the research, and which are treated as red.
  2. 02Security is still a proof-of-work assumption. The DAG does not replace the need for a majority of work.
  3. 03Parameter k, the width the protocol tolerates, is a deployment choice. It is not a constant of nature.

04 Load-bearing

The argument, and where a pitch drops it

  1. What the name has to mean

    The cut

    Kaspa implements a blockDAG ordered by GHOSTDAG, the PHANTOM line of research, so blocks that are not on a single chain can still be partially ordered.

    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

    It does not re-prove the PHANTOM theorem.

  2. What actually moves

    The cut

    Security is still a proof-of-work assumption. The DAG does not replace the need for a majority of work.

    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.

  3. What a later deployment may change

    The cut

    Parameter k, the width the protocol tolerates, is a deployment choice. It is not a constant of nature.

    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.

06 Divergence

What happened after the paper

A DAG that confirms faster in a diagram is not a finality gadget. Know which confirmation rule the docs name.

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

  1. 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

The PHANTOM paper is the research text already in this library. Kaspa is a network with parameters. Do not cite one as the other.

What the design proposes

  • Blocks reference multiple parents. The ordering rule decides which blocks are in the blue set, in the language of the research, and which are treated as red.
  • Security is still a proof-of-work assumption. The DAG does not replace the need for a majority of work.
  • Parameter k, the width the protocol tolerates, is a deployment choice. It is not a constant of nature.

How the mechanism is specified

  • Blocks reference multiple parents. The ordering rule decides which blocks are in the blue set, in the language of the research, and which are treated as red.
  • Security is still a proof-of-work assumption. The DAG does not replace the need for a majority of work.
  • Parameter k, the width the protocol tolerates, is a deployment choice. It is not a constant of nature.

What this page does not treat as proven

  • This note does not quote a block rate as a performance promise.
  • It does not re-prove the PHANTOM theorem.
  • A DAG that confirms faster in a diagram is not a finality gadget. Know which confirmation rule the docs name.

Why the desk still reads it

Kaspa implements a blockDAG ordered by GHOSTDAG, the PHANTOM line of research, so blocks that are not on a single chain can still be partially ordered.
