# EthStaker Call 2020/09/10 - Medalla Data Challenge

Three broad things we're looking for:
1. visualization, i.e. realtime website or dashboard
2. analysis, i.e. analyze some property of the network
3. new tooling for getting/preparing data

---

Some places to get data and things to look at:
1. block explorers API/scraping (i.e. [beaconcha.in](https://beaconcha.in), [blockaction](https://medalla.blockaction.io/))
- validator income/wealth distribution
- eth1 deposits x time
- block proposal -> inclusion funnel
- ...
2. http API of nodes
- client syncing comparison
- client connectivity comparison
- ...
3. network traffic using rumor/prrkl (https://github.com/protolambda/rumor, https://github.com/prrkl/imp)
- invalid block/attestation studies (i.e. DoS detection)
- speed of justification/finalization
- radius of network (would require multiple nodes)
- ...

3 is the hardest, but also the least explored!

---

Misc tool ideas:
- rumor/prrkl scripts
- ansible setups for collecting specific types of data from a set of nodes
- rumor/prrkl + jupyter notebook integration
