Note: Starting with Paris, updates are no longer rolled out based on block numbers. Paris was enabled once proof-of-work Total Difficulty reached 58750000000000000000000. As of Shanghai (at 1681338455), upgrade activation is based on timestamps.

Some clarifications were enabled without protocol releases:

EIP Block No.
EIP-2681 0
EIP-3607 0

Consensus Specification (work-in-progress)

The consensus specification is a python implementation of Ethereum that prioritizes readability and simplicity. It [will] accompanied by both narrative and API level documentation of the various components written in restructured text and rendered using Sphinx....

Usage

The Ethereum specification is maintained as a Python library, for better integration with tooling and testing.

Requires Python 3.8+

Building

Building the documentation is most easily done through tox:

$ tox -e doc

The path to the generated HTML will be printed to the console.

Live Preview

A live preview of the documentation can be viewed locally on port 8000 with the following command:

$ tox -e doc-autobuild
