Band: an oracle script executed by a validator set

Band Protocol. Band Protocol.

Band publishes oracle scripts: a request is executed by Band's validator set, and the result is signed back to the consumer chain.

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

    An oracle script is a program the validators run. If they all run it wrong, the signature is still valid and the data is still wrong.

  2. Claim 02 · Paper model

    The proposal

    Band publishes oracle scripts: a request is executed by Band's validator set, and the result is signed back to the consumer chain.

  3. Claim 03 · Paper model

    The mechanism

    A request names a script and parameters. Validators execute and sign. A threshold signature is what the consumer verifies.

  4. Claim 04 · Paper model

    The bound

    No validator count is copied here.

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

    An oracle script is a program the validators run. If they all run it wrong, the signature is still valid and the data is still wrong.

    Model

    What has to hold

    You are reading Band's docs. A particular script's sources are the fact a consumer must know.

    Falsifier

    What would retire it

    What sources does the script read?

  2. 02 The proposal

    Observation

    What the study says

    Band publishes oracle scripts: a request is executed by Band's validator set, and the result is signed back to the consumer chain.

    Model

    What has to hold

    You are reading Band's docs. A particular script's sources are the fact a consumer must know.

    Falsifier

    What would retire it

    What does the consumer verify?

  3. 03 The mechanism

    What the study says

    A request names a script and parameters. Validators execute and sign. A threshold signature is what the consumer verifies.

    No validator count is copied here.

03 Sequence

One action, as an operating tape

  1. 01A request names a script and parameters. Validators execute and sign. A threshold signature is what the consumer verifies.
  2. 02The script's sources are the trust root. The signature proves execution by the set, not truth of the sources.
  3. 03A relay to another chain adds a bridge assumption on top of the oracle assumption.

04 Load-bearing

The argument, and where a pitch drops it

  1. What the name has to mean

    The cut

    Band publishes oracle scripts: a request is executed by Band's validator set, and the result is signed back to the consumer chain.

    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

    No validator count is copied here.

  2. What actually moves

    The cut

    The script's sources are the trust root. The signature proves execution by the set, not truth of the sources.

    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 script can read a single website. Decentralised execution of a central source is still that source.

  3. What a later deployment may change

    The cut

    A relay to another chain adds a bridge assumption on top of the oracle assumption.

    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.

05 Register

What has to be true

  • Model · Not re-measured

    You are reading Band's docs. A particular script's sources are the fact a consumer must know.

  • 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

A script can read a single website. Decentralised execution of a central source is still that source.

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

An oracle script is a program the validators run. If they all run it wrong, the signature is still valid and the data is still wrong.

What the design proposes

  • A request names a script and parameters. Validators execute and sign. A threshold signature is what the consumer verifies.
  • The script's sources are the trust root. The signature proves execution by the set, not truth of the sources.
  • A relay to another chain adds a bridge assumption on top of the oracle assumption.

How the mechanism is specified

  • A request names a script and parameters. Validators execute and sign. A threshold signature is what the consumer verifies.
  • The script's sources are the trust root. The signature proves execution by the set, not truth of the sources.
  • A relay to another chain adds a bridge assumption on top of the oracle assumption.

What this page does not treat as proven

  • No validator count is copied here.
  • This is not Chainlink's white paper.
  • A script can read a single website. Decentralised execution of a central source is still that source.

Why the desk still reads it

Band publishes oracle scripts: a request is executed by Band's validator set, and the result is signed back to the consumer chain.

Terms, opened into the record

Oracle script
A program the validator set executes for a request.
Threshold signature
The proof the consumer checks. It proves the set signed, not that the source was right.
