Network Health

Current state of the validator set and cluster performance.

Active Validators
769
of 796 total, 27 offline
Delinquent Stake ? Percentage of total stake held by validators that are behind on voting. Below 1% is healthy.
0.03%
of total active stake
Skip Rate ? Stake-weighted average of leader slots skipped. Lower is better. A healthy network stays below 1%.

Decentralization

How distributed is stake across countries, networks, and individual validators?

Market Concentration (HHI) ? Herfindahl-Hirschman Index. Used in economics to measure market concentration. Below 1500 is competitive. Above 2500 means a few players dominate.

Imagine all validator stake as a market. HHI tells you how monopolized it is. A score near zero means thousands of equal players. A score near 10,000 means one player controls everything.

1466 by country Competitive
1383 by network provider Competitive
Stake Inequality (Gini) ? Gini coefficient measures inequality. 0 means all validators have equal stake. 1 means one validator holds all stake. Same scale economists use for wealth inequality.

Think of it like income inequality, but for stake. A high Gini means a few validators hold most of the stake, while hundreds of smaller validators share the rest.

0.752 across all validators High inequality
Nakamoto Coefficient ? Minimum number of independent entities that together control 33%+ of stake. Higher means more decentralized.
ASN ? One network provider (TERASWITCH) hosts enough validators to exceed 33% of stake alone. This is a known concentration risk in Solana infrastructure.
1
Critical
Country ? Two countries (US and Germany) together hold over 33% of stake. Geographic concentration creates regulatory and infrastructure risk.
2
Critical
City ? Two cities (Frankfurt and Amsterdam) together exceed 33% of stake. Most validators cluster in major European datacenter hubs.
2
Critical
Validator ? It takes 20 independent validators to reach 33% of stake. This is the strongest dimension - no single validator dominates.

Infrastructure Coverage

Adoption of advanced networking infrastructure across the validator set.

DoubleZero
? A private fiber network connecting Solana validators, bypassing the public internet for faster and more reliable block propagation.

About SONDA

What is SONDA?

SONDA started as private scripts to cross-verify validator geolocation while choosing a datacenter for the Solya validator. Existing tools reported conflicting locations, so we built a multi-source verification pipeline instead.

The result is an open-source observatory tracking where validators actually run, how infrastructure coverage evolves over time, and what decentralization looks like in practice.

What makes it different?

  • 4-source geo cross-verification per IP (DB-IP, IPInfo, GeoJS, ip-api)
  • Discrepancy detection - flags validators where sources disagree
  • Full location history since 2021 across 785+ epochs
  • DoubleZero and Jito BAM integration with live data
  • Three clusters: mainnet, testnet, devnet
  • Open source - github.com/SolyaUk/sonda
