Ethereum Whitepaper Explained for Beginners

A beginner-friendly walkthrough of the Ethereum whitepaper, including smart contracts, gas, accounts, and decentralized applications.

Start with the big idea

Ethereum was designed as a general-purpose blockchain. Instead of supporting only one form of digital money, it lets developers build applications with programmable rules.

Smart contracts in simple terms

A smart contract is code that runs on Ethereum. It can hold assets, apply rules, and respond automatically when someone interacts with it.

Why gas matters

Gas measures the computational cost of running actions on Ethereum. It helps the network price resources and prevents wasteful or abusive computation.

Accounts, transactions, and state

Ethereum keeps track of accounts and a shared global state. Transactions update that state, and contract calls can change stored data or trigger additional logic.

How to think about the whitepaper today

The 2014 document helps beginners understand the original design, but it does not fully represent Ethereum after many years of protocol upgrades and the move to proof of stake.
