Glassnode
Glassnode has opened a live latency monitor that streams round-trip timing from probes in 14 global cities to the crypto trading stack: every voting Solana mainnet validator (roughly 760 nodes), every active SUI validator with Mysticeti consensus, the Arbitrum One and Robinhood Chain sequencers, and WebSocket plus FIX feeds from Binance, Coinbase, Kraken, OKX, Bybit, Bitmex and Deribit. Coverage also extends to Pyth Lazer, Switchboard Crossbar and Chainlink Data Streams for oracle-dependent flow, plus Polymarket and Kalshi for prediction-market routing.
Why it matters
For market makers, arbitrage shops and MEV operators, co-location decisions have historically rested on vendor claims and guesswork. The dashboard publishes the actual numbers, including stake-weighted best-co-location rankings for Solana, Jito Block Engine paths across all eight regional endpoints, and time-to-quorum plus time-to-90% supermajority for SUI, which are the metrics that actually bound finality on a DAG-BFT chain. Robinhood Chain gets its own lane: ordering is strictly first-come-first-served with no fee-based priority, so physical distance to the sequencer is queue position. The same logic applies to Arbitrum's Timeboost express-lane bidders.
Market impact
The Solana readout already surfaces the kind of detail traders act on. This epoch, 67% of blocks are being produced in Europe, and Frankfurt is averaging 72ms round-trip against 140ms from US East. That kind of delta is what decides whether a validator connection is worth the hosting bill. The monitor does not move prices directly, but it lowers the information cost of every latency-sensitive strategy running against these venues, from cross-exchange arbitrage to validator-aware staking infrastructure.

Frequently asked questions
-
What does the Glassnode Latency Monitor actually measure?
It measures round-trip latency from probes in 14 cities to Solana and SUI validators, the Arbitrum One and Robinhood Chain sequencers, WebSocket and FIX feeds from major centralized exchanges, Pyth, Chainlink and Switchboard oracle gateways, and Polymarket and Kalshi prediction-market endpoints.
-
Why does latency matter for crypto trading specifically?
Physical distance to exchange matching engines and blockchain validators dominates total latency. A server in the wrong city can lose by tens to hundreds of milliseconds, enough to surrender arbitrage and MEV opportunities to better-located competitors.
-
How does it handle SUI differently from Solana?
For SUI, the monitor reports time-to-quorum and time-to-90% supermajority, the two metrics that bound transaction finality on a DAG-BFT chain running Mysticeti consensus. For Solana, it tracks QUIC handshake latency to every voting mainnet validator and exposes stake-weighted best-co-location rankings.
-
Where are the probes located?
Probes are deployed across Asia (Tokyo multi-AZ, Seoul, Hong Kong, Singapore), Europe (Amsterdam, Dublin, London, Frankfurt), the Americas (Ashburn, Ohio, Chicago, San Jose, São Paulo) and Oceania and Africa (Sydney, Johannesburg), running on Fly.io and AWS bare-metal instances.
-
What current Solana data does the dashboard surface?
As of the latest epoch, 67% of Solana blocks are being produced in Europe. Frankfurt averages 72ms round-trip latency while US East averages 140ms, a gap large enough to materially affect validator and Jito Block Engine co-location decisions.
