Validator Performance Tracker

Track blockchain validator and staking-node performance across Ethereum, Solana, and Cosmos — all from free, public APIs. No API key required.

What it does

For each validator, this Actor fetches live on-chain data and computes performance metrics that matter to stakers, node operators, and DeFi researchers:

Chain	Data Source
Ethereum (Beacon Chain)	beaconcha.in public API
Solana	Public mainnet-beta JSON-RPC
Cosmos Hub	cosmos-rest.publicnode.com

Use cases

• Staking dashboards: Monitor your validators' health at a glance
• Slashing risk alerts: Catch declining attestation effectiveness before a penalty
• Decentralisation research: Analyse voting power distribution across the Cosmos ecosystem
• Yield optimisation: Compare APR estimates and commission rates across validators

---

Notes

• No API key or proxy is required — all data sources are freely accessible
• beaconcha.in has a public rate limit; the Actor batches requests and adds polite delays
• Cosmos pagination is handled automatically — the Actor fetches all bonded validators before selecting the top N
• Solana delinquent validators are included and flagged with is_jailed: true
