Taproot class

This class encapsulates the construction of Taproot tweaked keys given an internal key and MAST consisting of Tapscript leaves constructed with TapBranch and TapLeaf objects.

Constructors

Taproot.new({required ECPublicKey internalKey, TapNode? mast})

Takes the internalKey to construct the tweaked key. The internal key will be forced to use an even Y coordinate and may not equal the passed internalKey. The mast represents a "Merkelized Abstract Syntax Tree" which is a tree of scripts that can be spent. This can be constructed via TapBranch and TapLeaf objects.

Properties

hashCode → int

final

leaves → List<TapLeaf>

A list of TapLeaf objects in the order that they appear in the MAST tree

final

mast → TapNode?

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

tweakedKey → ECPublicKey

Obtains the tweaked public key for use in a Taproot program

Methods

controlBlockForLeaf(TapLeaf leaf) → Uint8List

Given the exact leaf object provided to this Taproot object, this provides the control block data for inclusion in a script-path input.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

tweakPrivateKey(ECPrivateKey key) → ECPrivateKey

Takes a private key and tweaks it for key-path spending

Operators

operator ==(Object other) → bool

The equality operator.
