What Is the Difference Between Memory and Storage in Ethereum?

In computer science, memory refers to the devices used to store data or programs. Storage, on the other hand, is the medium where data is stored. Memory is generally categorized into two types: primary and secondary.

Primary memory is directly accessible by the CPU and is used to store data or programs that are currently being executed. Secondary memory is not directly accessible by the CPU and is used to store data or programs that are not currently being executed.

The most common type of primary memory is RAM (Random Access Memory). RAM is a volatile memory, meaning that it requires power to maintain the stored data. When power is removed from RAM, the stored data is lost.

The most common type of secondary memory is a hard disk drive (HDD). HDDs are non-volatile, meaning they do not require power to maintain the stored data.

Ethereum uses a decentralized virtual machine, which executes code on a blockchain network. The Ethereum Virtual Machine (EVM) makes use of something called gas in order to function.

NOTE: WARNING: Understanding the difference between memory and storage in Ethereum can be complicated and can have significant implications, both financially and legally. It is important to understand how Ethereum works, the risks associated with using Ethereum, and the potential legal and financial consequences of using it. Before using Ethereum, please consult a qualified professional who is knowledgeable about blockchain technology and Ethereum in particular.

Gas refers to the amount of computational effort that it would take to execute a particular instruction. In order for a transaction to be processed on the Ethereum network, it must include a certain amount of gas.

The EVM has its own internal storage, which is different from the storage on a computer’s hard drive. The EVM’s storage is called world state and it stores all of the current values for all of the contracts that have been deployed on the Ethereum network. The world state is stored in each full node’s database.

When a contract is created, its code and initial values are stored in world state. When the contract’s code is executed, the changes to world state are reflected in all full nodes’ databases.

The difference between memory and storage in Ethereum comes down to their respective functions. Memory refers to the devices used to store data or programs while storage refers to the medium where data is stored.

The EVM has its own internal storage called world state, which stores all of the current values for all of contracts deployed on the Ethereum network.
