Open-source project Solana Observatory for Network Decentralization Analysis
SONDA started in 2023 with a question every operator runs into: where
should a validator live? The basics were out there: how many
validators a datacenter hosts, how much stake it holds, which provider
stands behind an ASN. What was missing was a way to compare
datacenters by how their validators actually perform, across vote
credits, skipped slots, block times and more, side by side. That meant
writing scripts and watching validators by hand. SONDA grew out of
those scripts.
Today SONDA is an open-source observatory for Solana validators across
four clusters: mainnet-beta, testnet, the Alpenglow community cluster
and devnet, which most validator dashboards leave out. It shows where
validators run, with which providers and how well, where DoubleZero and
Jito BAM infrastructure is placed and who is connected to it, and turns
all of this into practical answers for operators. Mainnet data
refreshes every minute, and the dashboard is free to use.
I use SONDA myself to run Solya Validator. The move to Hong Kong in
September 2026 was decided with it: while building the datacenter
pages and filters, I compared cities and providers by stake
concentration, by how their validators perform and by the Jito BAM and
DoubleZero nodes nearby. You can do the same before choosing your next
datacenter.
- ⊕ Validators table with filters by client, version, country, city, provider, DoubleZero and Jito BAM, including exclude filters
- ⊕ Validator profiles with location, infrastructure, performance and links across clusters
- ⊕ Datacenters grouped by provider: cities, stake concentration, network infrastructure and performance
- ⊕ Chain vitals for every cluster: consensus, slot time, throughput and cluster status
- ⊕ Live checks of Jito, Harmonic and Solana endpoints
- ⊕ Where DoubleZero and Jito BAM infrastructure is placed, and which validators are connected to it
- ⊕ Cross-verified geolocation behind every record, with disagreements between sources flagged
