▪ MPT Ingredients : Merkle Tree + Prefix Tree + Custom Modification

▪ MPT Nodes : Leaf nodes + branch nodes + extension nodes

▪ State root : 256 bit hash of root

▪ Geth KV Store : levelDB

▪ Parity KV Store : rocksDB

▪ Tries :

1. Transaction Trie - mapping from transction hash → raw transactions

2. Transaction Reciept Trie - mapping from transaction hash → transaction execution Metadata

3. World State Trie - mapping from account address (including contracts) to account data

4. Account Storage Trie - mapping from integers to integers specific to an account/contract

Per the answer at [1], I’m still trying to understand if it’s one transaction trie per block or one for the entirety of the state.
