Ethereum uses a Key-Value based DB (leveldb). By using the hashed value of the address as the key and using the address as the path as shown in the picture on the below, you can find out the state value of the account. Ethereum Tries The Tries used in Ethereum are Storage Trie, State Trie, Transaction Trie, and Receipts Trie. Among these, the Root Hash value stored in the Block Header is State T..
