Compare the original Ethereum whitepaper with today’s Ethereum, including proof of stake, ecosystem growth, and the role of the Yellow Paper.

The original vision

The whitepaper presented Ethereum as a blockchain for smart contracts and decentralized applications. That core vision still matters and continues to define the platform.

What changed after launch

After launch, Ethereum grew into a large ecosystem with tokens, DeFi, NFTs, tooling, and infrastructure that go far beyond the examples in the original paper.

Proof of work to proof of stake

One of the biggest changes is Ethereum’s move to proof of stake. This means the original whitepaper is not a fully current description of the consensus layer today.

What stayed the same

The core ideas of programmable contracts, a shared execution environment, and a general-purpose blockchain are still central to Ethereum.

How to use the whitepaper now

The best way to read the Ethereum whitepaper today is as an original design document. Pair it with current documentation and the Yellow Paper for a fuller picture of modern Ethereum.
