+At initialization—the beginning of the chain's history—all leaf nodes are set to a default value, 
 which is typically a hash of a specific value, such as zero. Because all leaf nodes have the same 
 hash value, the parent nodes and higher-level nodes also have the same hash value. A node whose 
 hash is the default value for its level is therefore considered to represent an _empty_ subtree.
