ETH Blockchain: How It Works, What Runs on It, and How to Use an Explorer
The ETH blockchain is more than just a place to send and receive crypto.
It's a global network of computers running smart contracts, decentralized apps, and thousands of tokens — all without a central authority controlling any of it.
This guide breaks down how the ETH blockchain actually works, what coins and tokens run on it, and how to use a blockchain explorer to track everything happening on-chain.
- The blockchain is Ethereum's backbone — read our complete Ethereum guide for the full body.
Key Takeaways
- The ETH blockchain is a programmable network — unlike Bitcoin, it runs smart contracts that execute automatically without any middleman.
- Ethereum transitioned from proof-of-work to proof-of-stake in September 2022, cutting its energy consumption by over 99%.
- ETH is the native coin that powers the network, but thousands of additional tokens — including stablecoins like USDC and USDT — also live on the ETH blockchain.
- Token standards like ERC-20 (fungible) and ERC-721 (NFTs) define how assets are created and transferred across the Ethereum network.
- A blockchain explorer like Etherscan lets anyone track transactions, check wallet balances, and verify smart contracts on the ETH blockchain for free.
How the ETH Blockchain Works — and Why It's Not Like Bitcoin
Bitcoin and Ethereum are both blockchains — but they were built with very different goals in mind.
Bitcoin was designed to be digital money. The ETH blockchain was designed to be a programmable platform where developers can build almost anything.
That one difference changes everything about how the two networks work.
1. ETH Runs on Smart Contracts, Bitcoin Doesn't
A smart contract on the ETH blockchain is essentially a vending machine written in code — when called with the right inputs, it performs specific actions automatically, without any middleman.
Bitcoin's network can't do this. It records transactions. That's it.
The ETH blockchain takes things further by letting developers deploy programs that run exactly as coded, every time, with no possibility of censorship or interference.
2. ETH Switched to Proof of Stake — Bitcoin Hasn't
Ethereum transitioned to a proof-of-stake mechanism in 2022, citing improvements in energy efficiency and a foundation for future scaling — replacing the proof-of-work architecture the network launched with.
According to the Ethereum Foundation, that transition cut the network's energy consumption by over 99%.
Bitcoin still relies on proof-of-work, which requires vast amounts of computing power and electricity to validate transactions.
So yes — the ETH blockchain and Bitcoin are both blockchains, but they operate on fundamentally different rules.
3. The Ethereum Virtual Machine (EVM) Is the Engine Behind It All
At the core of the ETH blockchain is the Ethereum Virtual Machine (EVM) — a decentralized runtime environment where smart contracts are executed, and every participating node keeps an identical copy of its current state.
Think of the EVM as the operating system that every Ethereum app runs on.
It's what makes the ETH blockchain programmable — and the foundation that most decentralized applications and token projects are built on top of.

Coins and Tokens on the ETH Blockchain
ETH is the native coin of the Ethereum network — it's the fuel that powers every transaction and smart contract execution on the chain.
But ETH isn't the only asset living on the ETH blockchain.
The ERC-20 standard defines rules for fungible tokens — meaning each token is identical and interchangeable, just like ETH itself — while ERC-721 covers non-fungible tokens (NFTs), where each token represents something unique, like a piece of digital art or a collectible.
Because these standards exist, any developer can create a new token that works seamlessly across wallets, exchanges, and DeFi applications without rebuilding the infrastructure from scratch.
Some of the most widely held coins on the ETH blockchain include USDC and USDT — two dollar-pegged stablecoins that let users hold a stable value on-chain without converting back to traditional currency.
USDC is one of the most widely used US-regulated, fiat-backed stablecoins running on the Ethereum network.
Other tokens in the ETH blockchain coins list span DeFi governance tokens, wrapped assets, and utility tokens powering specific protocols — from lending platforms to decentralized exchanges.
The sheer range of coins and tokens is a key reason the ETH blockchain remains one of the most widely used smart contract networks in crypto.

How to Use an ETH Blockchain Explorer to Track Transactions
An ETH blockchain explorer is one of the most practical tools any crypto user can have.
Etherscan, the most widely used Ethereum (ETH) blockchain explorer, lets you search transactions, wallet addresses, token data, and all other activity taking place on the Ethereum network.
Here's how to use it, step by step:
- Go to etherscan.io — this is the official ETH blockchain scanner and requires no account to start exploring.
- Paste a wallet address into the search bar to see its full ETH balance, ERC-20 token holdings, and complete transaction history.
- Search a transaction hash (TXID) to confirm whether a transfer was successful, pending, or failed — and see exactly how much was sent and what gas fee was paid.
- Look up a token contract address to view the total supply, number of holders, and recent on-chain activity for any coin on the ETH blockchain.
- Use the Gas Tracker to check current network fees before sending a transaction, so you can time it when costs are lower.
- Verify a smart contract by entering its address and checking whether the source code has been publicly verified — an important step before interacting with any new protocol.
You can also access the ETH blockchain explorer directly from a wallet like MetaMask — just click "View on Explorer" from any account or transaction to jump straight to Etherscan.
Etherscan is free to use and works as a real-time ETH blockchain scanner, making it the go-to tool for anyone who wants to verify what's happening on-chain without relying on third parties.

FAQ
Q: Is ETH a blockchain?
ETH is the native currency of the Ethereum blockchain — so while ETH itself is a coin, the network it runs on is called the Ethereum blockchain (often referred to as the ETH blockchain).
Q: What is an ETH blockchain explorer?
An ETH blockchain explorer is a tool that lets you search, read, and verify any transaction, wallet address, or smart contract on the Ethereum network — Etherscan (etherscan.io) is the most widely used one.
Q: What is an ETH blockchain scanner used for?
An ETH blockchain scanner lets you confirm whether a transaction went through, check gas fees paid, and verify that a wallet address is legitimate — all in real time.
Q: How large is the ETH blockchain?
The ETH blockchain grows with every new block — validators add blocks roughly every 12 seconds, and the full archive data requirement continues to expand over time.
Q: Can I transact on the ETH blockchain via ETH only?
No — while ETH is required to pay gas fees for any transaction on the network, you can send ERC-20 tokens and interact with smart contracts using blockchain via ETH as the underlying fuel.
Conclusion
The ETH blockchain is the foundation of the decentralized internet — powering smart contracts, a growing list of coins and tokens, and tools like blockchain explorers that give anyone full transparency into on-chain activity.
Whether you're new to crypto or ready to go deeper, understanding how the ETH blockchain works puts you in a stronger position as an investor.
When you're ready to trade ETH, MEXC offers access to ETH and hundreds of tokens built on the Ethereum network — all in one place.
