The Ethereum blockchain stack consists of various components.
At the core, there is the Ethereum blockchain running on the peer-to-peer Ethereum network.
A Complete Guide to Understanding This Blockchain Concept
Secondly, there’s an Ethereum client (usually Geth) that runs on the nodes and connects to the peer-to-peer Ethereum network from where blockchain is downloaded and stored locally.
It provides various functions, such as mining and account management.
The local copy of the blockchain is synchronized regularly with the network.
Another component is the web3.js library that allows interaction with the geth client via the Remote Procedure Call (RPC) interface.
This architecture can be visualized in the following diagram: The Ethereum stack showing various components A formal list of all high-level elements present in the Ethereum blockchain is presented here: Keys and addresses Accounts Transactions and messages Ether cryptocurrency/tokens The EVM Smart contracts In , all of these one by one.
We will also discuss relevant technical concepts related to a high-level element within that section.
Why This Matters for Blockchain Technology
Understanding Components of the Ethereum ecosystem is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
