The Ethereum Foundation is thrilled to share the outcomes of the Medalla data challenge, a data-focused hackathon centered around the Medalla testnet 
The challenge was open-ended: we sought data tools, visualizations, and analyses of testnet data; essentially, anything that could assist the community in understanding the data better.
During a span of six weeks, we received 23 entries from diverse teams. We were delighted to witness high-quality submissions across all categories.
Prizes are categorized into three tiers based on their scope, extensibility, and benefit to the community.
Gold ($15k prize)
- Jim McDonald — chaind, a tool designed to extract data directly from an active eth2 client and store it in a PostgreSQL database. Notably, this tool was utilized by several other teams that entered the data challenge.
- Pintail — a collection of blog articles (1, 2, 3, 4, 5) analyzing client performance, examining network behavior, and evaluating validator efficiency.
Silver ($5k prize)
- Sid Shekhar and Elias Simos — a comprehensive study of eth2 data.
- Evgeny Medvedev of Nansen — an enhancement of the ethereum-etl tool tailored to eth2, along with a BigQuery database offering eth2 data.
- Nate McKervey of Splunk — a blog post and dashboard assessing the health of the Ethereum network.
Bronze ($1k prize)
Looking Ahead
The goals of this competition were to welcome fresh perspectives into the Ethereum community, encourage detailed analysis of eth2 data, simplify its interpretation, and offer important insights to both developers and the wider community. In this regard, the competition has been a resounding success, and we anticipate that many of the tools and analyses created will prove beneficial as the mainnet is launched.
If you’re interested in continuing the work initiated by any of these submissions, we encourage you to apply for a staking community grant!
