Hierarchical Deterministic Path Templates

The five-minute read

One action, walked through

1. Open BIP 88 and read the status line before the examples.
2. Write down the rule in one sentence. A fair version of that sentence is: This document describes a format for the representation of the templates that specify the constraints that can be imposed on BIP32 derivation paths.
3. Name the object that changes: BIP32, BIP43, MAY.
4. Ask what an old client, an old contract, or an offline counterparty does. If the document is silent, the silence is part of the design.

The argument, unpacked

What has to be true

• You are implementing BIP 88 at the status the text itself states: Complete.
• The object that has to change is BIP32, BIP43, MAY. A neighbouring document with a similar name is not this one.
• Status in the header is not adoption.

What happened after the paper

The source marks this complete. That is a statement about the text, not a promise that every wallet or node has shipped it. Later documents can narrow, replace, or ignore this one. Cite the number you mean.

What to check before you use the idea

• What must an implementation of Hierarchical Deterministic Path Templates accept, and what may it ignore?
• Is this consensus, peer policy, or an application interface?
• Which names does the text pin down: BIP32, BIP43, MAY?

Terms

BIP 88

The public text titled Hierarchical Deterministic Path Templates.

Complete

The document's own label for how finished the text is. It is not a market fact.

The problem the paper names

An interface that is only a name in a repository will be re-implemented differently by every team, which is how shared contracts break.

What the design proposes

• This document describes a format for the representation of the templates that specify the constraints that can be imposed on BIP32 derivation paths.
• The constraints specified by the templates allow to easily discern 'valid' paths, that match the constraints, and 'invalid' paths, that exceed the constraints.
• BIP32 derivation path format is universal, and a number of schemes for derivation were proposed in BIP43 and other documents, such as BIPs 44,45,49,84.

How the mechanism is specified

• Taken from the specification, the next constraint is: The constraints specified by the templates allow to easily discern 'valid' paths, that match the constraints, and 'invalid' paths, that exceed the constraints.
• Locate BIP32, BIP43, MAY in BIP 88 and apply it to one transaction or call.
• Then check the failure the class of rule always has: a node that did not upgrade, a reverted call, a replayed signature, or a peer that does not speak the message.

What this page does not treat as proven

• This document does not set a fee, a valuation, or a security proof.
• Status in the header is not adoption.
• The source marks this complete. That is a statement about the text, not a promise that every wallet or node has shipped it.

Why a venture studio still reads it

Use BIP 88 when a pitch says 'Hierarchical Deterministic Path Templates' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
