Parameters:

leftNode - the left child

rightNode - the right child

height - the height of the children

Returns:

the parent node

getLeaf

public byte[] getLeaf(byte[] vkey)

Calculates the leaf of a tree from the verification key.

Parameters:

vkey - the verification key to calculate the leaf from.

Returns:

the leaf
