MerkleTree class

Class representing a Merkle Tree

Constructors

MerkleTree({required List<Uint8List> leaves, required HashAlgo hashAlgo, bool isBitcoinTree = false})

Constructs a Merkle Tree. All nodes and leaves are stored as Uint8List. Lonely leaf nodes are promoted to the next level up without being hashed again.

MerkleTree.fromTree({required List<List<Uint8List>> layers, required HashAlgo hashAlgo, bool isBitcoinTree = false})

Properties

hashAlgo → HashAlgo

final

hashCode → int

The hash code for this object.

no setter, override

isBitcoinTree → bool

final

layers → List<List<Uint8List>>

Returns array of all layers of Merkle Tree, including leaves and root.

no setter

layersAsHex → List<List<String>>

no setter

root → Uint8List

Returns the Merkle root hash as a Buffer.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

getProof({required Uint8List leaf, int index = -1}) → List<MerkleProof>

Returns the proof for a target leaf. leaf is the target leaf for this proof. index is the target leaf index in leaves array. Use only if there are leaves containing duplicate data in order to distinguish it.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

verify({required List<MerkleProof> proof, required Uint8List targetNode, required Uint8List root}) → bool

Returns true if the proof path (array of hashes) can connect the target node to the Merkle root. proof is a list of MerkleProof objects that should connect target node to Merkle root. targetNode is the target node buffer. root is the Merkle root Buffer.

Operators

operator ==(Object other) → bool

The equality operator.
