 A _Merkle radix trie_ is a data structure that is both a [Merkle tree](https://en.wikipedia.org/wiki/Merkle_tree) and a [radix trie](https://en.wikipedia.org/wiki/Radix_tree). MerkleDB is an implementation of a persisted key-value store (sometimes just called "a store") using a Merkle radix trie. We sometimes use "Merkle radix trie" and "MerkleDB instance" interchangeably below, but the two are not the same. MerkleDB maintains data in a Merkle radix trie, but not all Merkle radix tries implement a key-value store.

+Like all tries, a MerkleDB instance is composed of nodes. Conceptually, a node has:
   * A unique _key_ which identifies its position in the trie. A node's key is a prefix of its childrens' keys.
   * A unique _ID_, which is the hash of the node.
   * A _children_ array, where each element is the ID of the child at that index. A child at a lower index is to the "left" of children at higher indices.
