Blockchain Node Monitoring for Validators and Operators
A single missed attestation costs you rewards. A prolonged outage costs you a slashing penalty. BlackTide monitors your nodes's sync status, peer count, and resource health so you know about problems in seconds - not after the damage is done.
Why validators get slashed while running "monitored" nodes
- Nodes fall out of sync gradually - generic uptime checks see HTTP 200 while the node misses blocks silently. Ethereum's staking documentation explains why node health goes far beyond simple availability checks. Ethereum staking documentation
- Slashing events compound over hours of downtime before any alert fires from a generic monitoring tool
- Generic alerts don't understand validator semantics: they can't distinguish a restart from a double-sign risk
- Scaling to 8 or 24 chains means managing 8 separate dashboards with no unified view or alert routing
Protocol-aware monitoring that catches problems before they cost you
- Real-time sync status and block height tracking per node detects desync within a single check interval
- Early slashing risk warnings detect extended downtime patterns before they cross the slashing threshold
- Resource usage monitoring - CPU, RAM, disk - with configurable threshold alerts before capacity is hit
- All protocols and all chains in a single dashboard with per-chain alert severity routing
- Operators running Geth, Erigon, or Lighthouse can monitor their execution and consensus clients through their exposed JSON-RPC and REST APIs - no agent required. Geth's JSON-RPC documentation covers the endpoints BlackTide uses. Geth JSON-RPC documentation
Capabilities
Purpose-built for the validator and node operator workflow
From sync status to slashing prevention - everything a serious operator needs in one place.
Tracks block height, peer count, and missed blocks for each node every 30 seconds - alerting before desync affects your validator duties. For Ethereum validators, a single missed attestation incurs a small penalty; a prolonged desync leading to inactivity leak can cost up to 50% of staked ETH over weeks. Early detection is the difference between a minor event and a material loss.
Detects downtime patterns that precede slashing events and fires an escalated alert while you still have time to intervene. The slashing threshold varies by protocol: Ethereum consensus clients slash for double-signing, while Cosmos SDK chains slash for downtime exceeding a configurable window. BlackTide applies the correct protocol logic for each chain automatically.
CPU, RAM, and disk usage tracked with configurable threshold alerts so you can provision capacity before your node runs out of runway. Blockchain nodes are notorious for disk space requirements - Ethereum archive nodes can exceed 12 TB. BlackTide tracks disk fill rate and alerts before capacity is hit, giving you time to provision storage rather than scramble during an outage.
Ethereum (Geth, Lighthouse, Prysm), Cosmos SDK validators, Solana, and Polkadot - all covered with protocol-aware health checks. Ethereum execution clients (Geth, Erigon, Besu, Nethermind) and consensus clients (Lighthouse, Prysm, Teku, Nimbus) are all supported via their respective JSON-RPC and REST APIs. No code changes or agent installations on your infrastructure.
Route P0 slashing risk alerts to Telegram immediately, P1 sync warnings to Slack, and P3 resource alerts to email - per team and per chain. Routing rules are configurable per chain and per team, so the Cosmos team sees Cosmos alerts and the Ethereum team sees Ethereum alerts - without either team being paged for the other's incidents.
Use Cases
Built for the people running production blockchain infrastructure
Cosmos validator across 8 chains
Monitoring 8 Cosmos SDK chains with separate explorers and dashboards is untenable. BlackTide unifies all nodes in one view with per-chain alert routing to your on-call rotation.
Ethereum solo staker watching for missed attestations
Missed attestations compound quietly. BlackTide's 30-second checks detect when your beacon client loses sync and alerts you before a small issue becomes a significant penalty.
Solana RPC operator tracking sync lag and peers
Solana's high throughput makes sync lag especially costly. BlackTide tracks slot height, peer count, and RPC response time - alerting the moment your node starts falling behind.
BlackTide vs generic monitoring for node operators
Generic tools see an HTTP response. BlackTide understands what it means.

Used by
Monitoring for Validators and Node Operators
Slashing is game over - institutional validators and RPC providers need monitoring that speaks blockchain, not just HTTP.
Monitoring for DAOs and Onchain Governance
DAOs manage billions in treasury across dozens of chains - multisig approvals, governance executions, and treasury movements need real-time visibility.
Never miss a block again.
Know before your users know. Before the slashing event. Before the downtime penalty.
