The Ethereum Virtual Machine (EVM) is a Turing-complete virtual machine that allows for the execution of smart contracts on the Ethereum blockchain. The EVM makes it possible for developers to create decentralized applications (dApps) that can run exactly as programmed without any possibility of fraud or third party interference.
State in Ethereum refers to the current status of a smart contract, which is stored in the EVM. The state of a smart contract can be changed by transactions that are sent to it.
Every transaction results in a state change, and the new state is reflected in the blockchain.
The state of a smart contract includes the storage, balance, and code of the contract. The storage is where data associated with the contract is stored.
The balance is the amount of ether that is held in the contract’s address. The code is the contract’s program code, which is executed when the contract is called.
NOTE: WARNING: Understanding the concept of State in Ethereum can be a complex process. Before attempting to learn and use this concept, please make sure you have a solid foundation in the basics of blockchain technology, cryptography, and programming. Trying to learn this concept without the necessary background knowledge may lead to confusion and frustration.
The state of a smart contract can be changed by any transaction that is sent to it. This includes transactions that are sent by other contracts, as well as transactions that are sent directly to the contract’s address.
When a transaction changes the state of a smart contract, the new state is reflected in the blockchain.
The state of a smart contract can also be changed by calls to its methods. When a method is called, its code is executed and may result in a state change.
The new state is reflected in the blockchain when the method call completes.
In summary, State in Ethereum refers to the current status of a smart contract, which is stored in the EVM and reflected in the blockchain. The state of a smart contact can be changed by transactions and method calls.

An epoch is a time period in which a particular set of events or developments takes place. In the context of Ethereum, an epoch is a period during which a particular set of validators are chosen to be responsible for creating and finality of new blocks on the Ethereum blockchain. The selection of validators for each epoch is based on a process known as “proof of stake” (PoS).
