Chia: proofs of space and time as a consensus
Chia protocol. Bram Cohen and the Chia Network.
Chia publishes consensus from proofs of space, checked across time, so farmers allocate disk rather than continuous hash power.
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
The proofs-of-space research already in this library is the idea. Chia's consensus introduction is the network's document, including the time-lord or equivalent role it names.
Claim 02 · Paper model
The proposal
Chia publishes consensus from proofs of space, checked across time, so farmers allocate disk rather than continuous hash power.
Claim 03 · Paper model
The mechanism
A farmer proves they allocated space. A timelord or the docs' equivalent orders the proofs in time so that grinding the challenge is slow.
Claim 04 · Paper model
The bound
This note does not quote netspace.
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
The proofs-of-space research already in this library is the idea. Chia's consensus introduction is the network's document, including the time-lord or equivalent role it names.
Model
What has to hold
You are reading Chia's consensus introduction. The research paper on proofs of space is the other study.
Falsifier
What would retire it
What does a winning proof demonstrate?

03 Sequence
One action, as an operating tape
- 01A farmer proves they allocated space. A timelord or the docs' equivalent orders the proofs in time so that grinding the challenge is slow.
- 02The quality of a proof decides the winner of a slot. Space alone, without the time delay, is not the consensus.
- 03Pooling, if documented, shares rewards. It does not change who finds the proof.
04 Load-bearing
The argument, and where a pitch drops it
What the name has to mean
The cut
Chia publishes consensus from proofs of space, checked across time, so farmers allocate disk rather than continuous hash power.
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 academic proofs-of-space paper remains a separate study.
What actually moves
The cut
The quality of a proof decides the winner of a slot. Space alone, without the time delay, is not the consensus.
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 say disk farming is energy-free. It says the scarce resource the docs name is space and time, not repeated hashing.
What a later deployment may change
The cut
Pooling, if documented, shares rewards. It does not change who finds the proof.
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.

The academic proofs-of-space paper remains a separate study.
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.

The paper, in the order a builder needs
The problem it names
The proofs-of-space research already in this library is the idea. Chia's consensus introduction is the network's document, including the time-lord or equivalent role it names.
What the design proposes
- A farmer proves they allocated space. A timelord or the docs' equivalent orders the proofs in time so that grinding the challenge is slow.
- The quality of a proof decides the winner of a slot. Space alone, without the time delay, is not the consensus.
- Pooling, if documented, shares rewards. It does not change who finds the proof.
How the mechanism is specified
- A farmer proves they allocated space. A timelord or the docs' equivalent orders the proofs in time so that grinding the challenge is slow.
- The quality of a proof decides the winner of a slot. Space alone, without the time delay, is not the consensus.
- Pooling, if documented, shares rewards. It does not change who finds the proof.
What this page does not treat as proven
- This note does not quote netspace.
- It does not say disk farming is energy-free. It says the scarce resource the docs name is space and time, not repeated hashing.
- The academic proofs-of-space paper remains a separate study.
Why the desk still reads it
Chia publishes consensus from proofs of space, checked across time, so farmers allocate disk rather than continuous hash power.
09 Lexicon
Terms, opened into the record
- Proof of space
- A demonstration that a farmer stored a specified table.
- Timelord
- The role that supplies the delay. If the docs use another name, use that name.
