// Package nomtdb implements the triedb backend for NOMT (Near-Optimal Merkle
// Trie), a page-based binary merkle trie engine.

// NOMT handles only the trie structure (merkle pages). Flat key-value storage
// (accounts, storage slots) is stored in geth's existing ethdb (PebbleDB)
// under NOMT-specific key prefixes.
