tBTC: bitcoin custody by a signer set with a redemption flow

Threshold tBTC. Threshold Network.

tBTC publishes a redemption path from a token back to bitcoin, with custody held by a signer set, rather than by a single custodian's published IOU.

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

    A bitcoin token with a redemption flow is still a claim on signers until the bitcoin transaction confirms. The signers are the bridge.

  2. Claim 02 · Paper model

    The proposal

    tBTC publishes a redemption path from a token back to bitcoin, with custody held by a signer set, rather than by a single custodian's published IOU.

  3. Claim 03 · Paper model

    The mechanism

    A deposit is acknowledged and a token is minted when the signer set the docs name accepts the Bitcoin transaction.

  4. Claim 04 · Paper model

    The bound

    No bitcoin total is stated 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

    A bitcoin token with a redemption flow is still a claim on signers until the bitcoin transaction confirms. The signers are the bridge.

    Model

    What has to hold

    You are reading the Threshold tBTC docs. A custodial wrapped bitcoin is a different product.

    Falsifier

    What would retire it

    What token supply rule does a deposit trigger?

  2. 02 The proposal

    Who must sign a peg-out?

03 Sequence

One action, as an operating tape

  1. 01A deposit is acknowledged and a token is minted when the signer set the docs name accepts the Bitcoin transaction.
  2. 02Redemption burns or locks the token and asks the signers to pay a Bitcoin output. The wait is a Bitcoin confirmation plus the signer protocol.
  3. 03A signer-set rotation is a key event. The docs' penalty for a signer who refuses is part of the design.

04 Load-bearing

The argument, and where a pitch drops it

  1. What the name has to mean

    The cut

    tBTC publishes a redemption path from a token back to bitcoin, with custody held by a signer set, rather than by a single custodian's published IOU.

    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 bitcoin total is stated here.

  2. What actually moves

    The cut

    Redemption burns or locks the token and asks the signers to pay a Bitcoin output. The wait is a Bitcoin confirmation plus the signer protocol.

    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 bitcoin total is stated here.

  3. What a later deployment may change

    The cut

    A signer-set rotation is a key event. The docs' penalty for a signer who refuses is part of the design.

    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 merchant or a front end is not the signer set.

What has to be true

  • Stake and threshold · Not re-measured

    You are reading the Threshold tBTC docs. A custodial wrapped bitcoin is a different product.

  • Model · Not re-measured

    The document is the one at the source URL. A marketing page with the same brand is not this text.

06 Divergence

What happened after the paper

A merchant or a front end is not the signer set.

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 bitcoin token with a redemption flow is still a claim on signers until the bitcoin transaction confirms. The signers are the bridge.

What the design proposes

  • A deposit is acknowledged and a token is minted when the signer set the docs name accepts the Bitcoin transaction.
  • Redemption burns or locks the token and asks the signers to pay a Bitcoin output. The wait is a Bitcoin confirmation plus the signer protocol.
  • A signer-set rotation is a key event. The docs' penalty for a signer who refuses is part of the design.

How the mechanism is specified

  • A deposit is acknowledged and a token is minted when the signer set the docs name accepts the Bitcoin transaction.
  • Redemption burns or locks the token and asks the signers to pay a Bitcoin output. The wait is a Bitcoin confirmation plus the signer protocol.
  • A signer-set rotation is a key event. The docs' penalty for a signer who refuses is part of the design.

What this page does not treat as proven

  • No bitcoin total is stated here.
  • This is not wBTC's custodian model, and this note does not describe wBTC.
  • A merchant or a front end is not the signer set.

Why the desk still reads it

tBTC publishes a redemption path from a token back to bitcoin, with custody held by a signer set, rather than by a single custodian's published IOU.

Terms, opened into the record

Signer set
The threshold that custodies bitcoin. It is the trust assumption.
Redemption
The protocol path back to a Bitcoin output. A market sale of the token is not this path.
