Nodes.Guru

Nodes.Guru is a professional blockchain infrastructure and staking provider operating since 2019, with roots in the industry stretching back to 2016. The team describes itself as "more than a leading blockchain validator," reflecting a deliberate expansion from pure node operation into tooling, analytics, and developer services that span the broader proof-of-stake ecosystem.

The Problem Nodes.Guru Addresses

Running a validator node on high-performance networks like Solana requires specialized hardware, low-latency connectivity, round-the-clock monitoring, and deep protocol knowledge. For most token holders, operating their own infrastructure is impractical. At the same time, delegating to an unknown provider carries real risk: downtime or misbehavior can trigger slashing penalties that directly reduce a delegator's stake. Nodes.Guru positions itself as a solution to this reliability gap, targeting both retail delegators and institutional allocators who need consistent uptime, transparent reporting, and professional-grade security practices without managing nodes themselves.

Validator Operations

Nodes.Guru runs validators across 44 mainnet networks, including Solana, Aptos, Sui, Celestia, Ethereum, Layer Zero, dYdX, Sei, Nibiru, Babylon, Aleo, Evmos, Juno, Casper, and others. The infrastructure mix combines bare-metal servers with selective use of cloud providers — OVH, Latitude, Vultr, DigitalOcean, Hetzner, and AWS — spread across a global footprint covering regions from Chile to Singapore and Los Angeles to India. For mainnet deployments, Nodes.Guru typically employs failover clusters to maintain continuity if a primary machine goes offline.

Monitoring runs continuously via Zabbix and Grafana, with a Telegram-based alert system that sends instant notifications when a node goes offline or performance degrades. The organization offers a 100% slash-compensation policy, covering delegators in the event of an incident attributable to Nodes.Guru's own infrastructure failures.

Staking Metrics

As of data reflected on the live Nodes.Guru website, the platform holds approximately $79.8 million in assets staked across its validator set, with roughly 60,170 delegators. The team consists of 15 professionals. An announcement published on Medium claimed the organization had secured over $600 million in assets cumulatively — a figure that likely reflects total volume handled across all network participation over the provider's history rather than a single-point snapshot.

On Staking Rewards, Nodes.Guru holds an AAA rating (Qualified Grade) assessed across business, operations, reliability, and security dimensions, achieving a 5.0/5 score in both Delegator Protection and On-Chain Metrics categories.

Explorers.Guru

One of Nodes.Guru's flagship public-facing products is Explorers.Guru, a suite of blockchain explorers covering more than 60 networks. These explorers surface data on validator performance, governance participation, and staking analytics. They serve both delegators performing due diligence on validators and projects that embed Nodes.Guru-built tooling into their own ecosystem resources. The organization also maintains validator profile repositories on GitHub — including explorers-registry and explorer-validator-profiles — to keep cross-chain validator metadata organized and publicly accessible.

Testnet Aggregator

Nodes.Guru operates what it describes as the most-visited testnet guide aggregator in crypto. The platform catalogs testnets across all stages of development, with approximately 18 active testnets, 7 upcoming, and 281 ended networks documented as of mid-2025. Each listing includes setup guides, hardware requirements, and installation scripts, lowering the barrier for node operators who want to participate in early networks before mainnet launch.

Beyond aggregation, Nodes.Guru offers end-to-end testnet consulting for projects, covering strategy, technical setup, and the path from testnet to mainnet launch. The team's track record as early participants in testnet environments across networks like Aptos, Sui, Celestia, Allora, and dozens of others is reflected in their current mainnet presence: early testnet participation has historically converted into mainnet validator slots.

Open-Source Tooling

The Nodes.Guru GitHub organization publishes infrastructure tools built during active validator work and released publicly. Notable repositories include tenderduty (Go, MIT license), a validator notification system for Cosmos and Tendermint networks that alerts when validators miss pre-commits; casper-world and its backend (TypeScript), network monitoring tools for the Casper chain tracking node version distribution and stake concentration; celestia-bridge-healthcheck (Shell, MIT license), a health monitoring script for Celestia bridge nodes integrated with Healthchecks.io; and ethereum-event-forwarder, a bridge utility for Ethereum event processing used by Vega validators.

Staking Products

Beyond raw validator operation, Nodes.Guru has launched user-facing staking portals. Aptostake.Guru provides a dedicated interface for Aptos token holders. The platform's blog covers technical tutorials and project analyses across networks including Aztec, Berachain, Story Protocol, Allora, Initia, Babylon, and Monad, serving delegators evaluating where to stake and developers scouting for validator partners.

Team and Background

The founding team includes Sergio Korolev (Founder and CEO), Evgeny Garanin (Co-founder and COO), Andrei Menshikov (Co-founder and CTO), and Andres Khovan (Co-founder and CMO). The team has been active in blockchain infrastructure since 2016, predating the formal founding of Nodes.Guru in 2019.

Solana Ecosystem Fit

Nodes.Guru participates in Solana as one of the networks in its multi-chain validator portfolio. Solana's performance demands — sub-second finality, high transaction throughput, and strict hardware requirements — align with the infrastructure profile Nodes.Guru maintains globally. Delegators looking for a professional validator with a documented multi-network track record, an AAA certification from Staking Rewards, and a stated slash-compensation guarantee can delegate SOL to Nodes.Guru's validator as part of the broader ecosystem of institutional-grade staking providers active on Solana.
