 ((("hierarchical deterministic (HD) wallets")))Keys in an HD wallet are identified using a "path" naming convention, with each level of the tree separated by a slash (/) character (see <<table_4-8>>). Private keys derived from the master private key start with "m." Public keys derived from the master public key start with "M." Therefore, the first child private key of the master private key is m/0. The first child public key is M/0. The second grandchild of the first child is m/0/1, and so on.
 
-The "ancestry" of a key is read from right to left, until you reach the master key from which it was derived. For example, identifier m/x/y/z describes the key that is the z-th child of key m/x/y, which is the y-th child of key m/x, which is the x-th child of m.
