The state entries in the Ethereum blockchain represent the current state of the blockchain. This includes the current state of all account balances, contract code and storage, and pending transactions. The state entries are used by the Ethereum Virtual Machine (EVM) to determine the outcome of a transaction.

Q: What is a state in Ethereum?
A: In Ethereum, a state is represented by a data structure called a Merkle Patricia Tree. This data structure contains all of the current values for all accounts in the Ethereum network. The tree is named after its inventor, Ralph Merkle, and Patricia, a computer scientist who developed the data structure.
Q: How is state stored in Ethereum?
A: Ethereum state is stored in a data structure called a trie.
A trie is a directed acyclic graph (DAG) where each node has up to 16 child nodes.
Each node in the trie has a unique identifier (ID), which is the hash of the node’s data.
The data in each node is the value associated with the node’s ID.
The trie is stored in a file called the state trie.
Q: What are types of accounts possible in an ethereum Blockchain?
A: There are two types of accounts in an Ethereum blockchain: externally owned accounts (EOAs) and contract accounts.
EOAs are controlled by private keys and can send transactions to interact with smart contracts. Contract accounts are controlled by their contract code and can interact with other contract accounts.
Q: Where is state stored blockchain?
A: The state of a blockchain is stored in a data structure called a “blockchain”. This data structure is a linked list of blocks, where each block contains a snapshot of the state of the blockchain at a particular point in time. The state of the blockchain is the collection of all the data in all the blocks in the blockchain.
