How to submit

  1. Collect and analyze Medalla data – See tips for getting started
    Either with existing tools
    Or for the extra ambitious, build your own tool and tell us about it!
  2. Detail out your work in a blog post
  3. Submit

How to get started

  • Join the testnet via the Medalla testnet launchpad and run / sync a client (or multiple clients). The launchpad will give you more details.
  • Experiment with a client API for single node statistics.
  • Experiment with rumor to get data from group of clients.
    • rumor is an interactive shell to run the Eth2 network stack, attach to testnets, debug clients, and extract data for tooling.
  • Dig around a block explorer:
  • Crunch some numbers and spin up some graphs.
  • Publish your analysis or visualization


What you can do

  • What data visualizations can show the health of the Medalla test network?
  • Aggregation performance. Latencies. Validator effectiveness. Gini coefficients. Block rewards. What compelling story can you tell with Medalla data?
  • What performance and behavior patterns can you find among different classes of validators (for example hobbyists, institutional players, exchanges, and stakers)?
  • What patterns exist in slashings?
  • What other data can you collect and analyze on Medalla?
  • What new tools can you build to collect and analyze data on Medalla?

The challenge

Document your best Medalla data insights in the most readable blog post possible – for prizes.

The Ethereum Foundation are running this challenge because there's a lot to learn and discover from Medalla testnet activity. Your findings will give the Ethereum community —from beginners to core researchers— important insight into Medalla, the last step en route to Phase 0, the Beacon Chain.


  • Blog post must be in English.
  • There are no length requirements.
  • Blog posts must be public and original.
  • Data analysis or visualization must concern Medalla testnet data.
  • Tools and scripts used (and created) must be open source and referenced in the blog post.

Judging criteria

  • Overall quality and clarity of data analysis or data visualization.
  • Quality of insights into Medalla, clients, and Eth2 in general.
  • Insights that lead to substantive changes in client implementations or specifications.
  • Analyses or visualizations that help a non-technical audience gain insight into the network.
  • Quality of contribution to the Eth2 tooling ecosystem (if applicable).


The Ethereum 2.0 Medalla testnet is live. Validators are validating. Attesters are attesting. Blocks are propagating. Which means, data, lots and lots of data. The Ethereum community needs help to make sense of it all.
