GetKeyForDestination()

CKeyID GetKeyForDestination	(	const SigningProvider &	store,
		const CTxDestination &	dest
	)

Return the CKeyID of the key involved in a script (if there is a unique one).

InferTaprootTree()

std::optional< std::vector< std::tuple< int, std::vector< unsigned char >, int > > > InferTaprootTree	(	const TaprootSpendData &	spenddata,
		const XOnlyPubKey &	output
	)

Given a TaprootSpendData and the output key, reconstruct its script tree.

If the output doesn't match the spenddata, or if the data in spenddata is incomplete, std::nullopt is returned. Otherwise, a vector of (depth, script, leaf_ver) tuples is returned, corresponding to a depth-first traversal of the script tree.

Data structure to represent the nodes of the tree we're going to build.

Hash of this node, if known; 0 otherwise.

The left and right subtrees (note that their order is irrelevant).

If this is known to be a leaf node, a pointer to the (script, leaf_ver) pair. nullptr otherwise.

Whether or not this node has been explored (is known to be a leaf, or known to have children).

Whether or not this node is an inner node (unknown until explored = true).

Whether or not we have produced output for this subtree.
