EthereumTimeMachine

Tools to run historical Ethereum clients and related workflows.

Overview

The Ethereum Time Machine project enables running authentic historical Ethereum software on contemporary hardware. It consists of three phases:

  1. Chain of Geths - Protocol bridge infrastructure to sync historical chaindata
  2. Resurrection - GPU mining to extend historical chains to CPU-mineable difficulty
  3. Running Mist - Authentic Mist wallet experience on historical chains

Chain of Geths

A Docker Compose stack of multiple Geth versions (plus Lighthouse) where adjacent nodes share overlapping eth/* subprotocols, enabling modern clients to sync historical chaindata to ancient Geth versions.

See chain-of-geths/README.md

Resurrection

GPU mining to crash difficulty from 62.38 TH to CPU-mineable levels.

Option Time Cost Blocks
Homestead (recommended) ~8 days ~$180 ~320
Frontier ~19 months ~$14,000 ~26,500

See resurrection/README.md

Running Mist

Run the original Mist wallet against historical Geth versions via IPC.

Geth Mist Era
v1.1.0 v0.2.6 Frontier
v1.3.6 v0.7.4 Homestead

See running-mist/README.md
