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.
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.
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.
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.
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.
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?

03 Sequence
One action, as an operating tape
- 01A deposit is acknowledged and a token is minted when the signer set the docs name accepts the Bitcoin transaction.
- 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.
- 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
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.
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.
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.

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