Blockchain Infrastructure & Node DevOps
Blockchain infrastructure is the production layer that keeps a network usable: validators, full nodes, RPC endpoints, block explorers, indexers, and monitoring, operated by one of the top DevOps teams in Web3.
Blockchain infrastructure is the production layer that keeps a network usable: the validator and full nodes, RPC endpoints, block explorers, indexers, and monitoring that every developer and user silently depends on. It is unglamorous, operationally demanding, and when it fails the whole ecosystem feels it.
Most teams underestimate exactly how much engineering sits behind reliable uptime until it breaks. Protofire runs that layer for chains, foundations, and protocols in production. We are one of the top DevOps teams in Web3: a Filecoin infrastructure partner since 2021, a top-3 indexer in The Graph ecosystem, and the operator behind validator and RPC fleets across dozens of networks.
This is not a generic cloud you rent by the hour; it is blockchain digital infrastructure designed, deployed, and operated by engineers who know how each client and protocol actually behaves under load. We work with EVM L1/L2 chains and ecosystem foundations that want professionalized operations (better reliability metrics, usage analytics, and a trusted node-operator partner) without pulling their core team off chain priorities.
If you are scaling mainnet traffic, launching an ecosystem, or tired of developer complaints about RPC quality, that is exactly the problem we solve.
A blockchain infrastructure stack has six operational layers
Each layer is a distinct operational responsibility. We run all six.
Validators
Full & archive nodes
RPC endpoints
Block explorer
Indexing & subgraphs
Monitoring & analytics
What we run
Nodes are the foundation of network security, and a public RPC is the front door every developer walks through. We deploy and operate full, light, and archival nodes and high-performance, customized RPC endpoints for networks, platforms, and protocols, with load balancing, caching, and one-line integration so consumers can swap endpoints without touching their stack.
Running RPC well is a mindset, not a server: accessible APIs, community feedback loops, and continuous tuning. We do this in production for Filecoin, where our work on the Glif RPC layer reached 99.95%+ uptime, sub-800ms retrieval, and a 240% rise in developer usage to 30,000+ monthly developers. (More detail on our dedicated RPC node hosting page.) Benefits: faster deployment · stable, observable endpoints under real traffic · predictable infrastructure cost · one team accountable for uptime.
We set up and maintain validator-node infrastructure so chains and stakers can outperform on the metrics that matter (TVL, MAU, liquidity, APR, uptime, and economical efficiency) without managing nodes in-house. Our engineers run validators, miners, indexers, witnesses, relayers, fishermen, sentinels, and more across the ecosystem, and have operated infrastructure for networks including Fuse, Meter, CrossFi, Stratos, DFK, Avalanche, Secret Network, Lava Network, and Fluence.
Deployments typically go live in a few weeks. (See the dedicated Validators page.) Benefits: higher APR and uptime · hardened validator-node security · decentralization without in-house ops · deploy in weeks, not quarters.
A network without a block explorer is a network developers cannot debug or trust. We deploy and customize Blockscout explorers so your chain ships with a production-grade, open-source explorer from day one: block, transaction, token, and contract views, source-code verification, and a public API builders can query directly.
Because Blockscout is open-source, there is no vendor lock-in and no per-seat licensing as the network grows. The work is rarely a stock install: high-throughput chains need custom ingestion and indexing tuning to keep the explorer in lockstep with the chain. For Somnia, an EVM L1 pushing bursts of up to one million TPS, we deployed and optimized a Blockscout explorer that indexed up to 103 million transactions in a single day during testnet, serving that data to users and developers within seconds of finality. Benefits: explorer live at mainnet · transparent, debuggable transactions · a credibility signal for builders and users · fully open-source, no vendor lock-in.
Applications need fast, queryable on-chain data. As a top-3 indexer in The Graph ecosystem, we run indexing infrastructure and build and operate subgraphs so dApps get the data layer they require without standing up their own indexing stack. Paired with our oracle integration work, such as the Chainlink-compatible stack we shipped for Somnia in 92 days, this rounds out the read and data side of a network. Benefits: low-latency on-chain queries · reliable subgraph operations · a complete data layer (indexing + oracles) for ecosystem dApps.
Reliability you cannot measure is luck. We instrument every deployment with monitoring, observability, and usage analytics from day one (request volumes, error rates, latency percentiles, and per-endpoint demand), so capacity and cost decisions are driven by data instead of guesswork.
We run our own internal tooling for this: Proteus Shield for usage analytics, billing, caching, and monitoring, and Genesis Ark for streamlined IPC/appchain network deployment. At scale the payoff is concrete: on Filecoin, a network now handling 4+ billion node requests a month, disciplined monitoring and node tuning pushed Glif-managed RPC uptime to 99.95%+, against the ~97-98% baseline typical of decentralized environments.
Because we run much of this on optimized and bare-metal hardware rather than blindly on managed cloud, run-cost stays predictable as usage grows, and scaling becomes a measured decision rather than a surprise invoice. Benefits: data-driven scaling, not guesswork · observability and incident response from day one · meaningful cost optimization vs naive cloud · usage analytics, not server hosting alone.

One of the top blockchain infrastructure teams in Web3
Protofire is a blockchain infrastructure company and development partner that has shipped 250+ projects since 2016 (spun out of Altoros), across 60+ networks and 95+ protocols. On the infrastructure side specifically: we are a Filecoin infrastructure partner since 2021 (our Glif RPC work was praised as a #1 project in Filecoin's RetroPGF round), a top-3 indexer in The Graph ecosystem, an official Safe Guardian, and the maintainer of Solhint, the open-source Solidity linter used by 1M+ developers.
We run validator and RPC fleets across networks including Avalanche, Fuse, Meter, Stratos, Secret Network, and Lava, and operate our own productized tooling, Proteus Shield and Genesis Ark, that most blockchain infrastructure companies simply do not have. When we recommend an architecture, it is one we already run in production.
The proof is operational: 99.95%+ RPC uptime and a 240% jump in developer usage for Filecoin, a Blockscout explorer built to scale toward one million TPS for Somnia, a Chainlink-compatible oracle stack delivered in 92 days, and a rebuilt Gnosis explorer holding 99.99% uptime across 300,000+ validated addresses while lifting developer activity 40%. That is what the best blockchain infrastructure looks like in practice: measured in uptime, latency, and developer growth, not slideware.
“Blockchain infrastructure is unglamorous and operationally demanding, and when it fails the whole ecosystem feels it.”
We lifted RPC uptime from the ~97-98% decentralized baseline to 99.95%+ through disciplined node tuning and monitoring, while developer usage grew 240% to 30,000+ monthly developers. This is managed blockchain infrastructure measured in uptime and developer growth, not slideware.
Node Operations: Self-Hosted vs Managed Infrastructure
| Self-Hosted Nodes | Generic cloud | Protofire Managed Infrastructure | |
|---|---|---|---|
| Operational expertise | Requires DevOps/SRE hiring and training | Generic cloud ops, not blockchain optimized | Blockchain-specialist team (validators, RPC, monitoring) |
| Reliability & uptime | Depends on your team capacity (typically 95-98%) | ~97-98%, but not blockchain optimized | 99.95%+ (Filecoin Glif benchmark), blockchain-tuned |
| Scaling costs | Manual provisioning, unpredictable as traffic grows | Surprise cloud invoices at scale; not optimized for RPC | Bare-metal hardware, predictable cost as usage grows |
| Infrastructure layers | DIY: nodes, RPC, explorer, indexing, monitoring | Generic compute, no blockchain tooling | Full stack: validators, RPC, Blockscout, subgraphs, Proteus Shield monitoring |
| Time to production | Weeks-months to architect and deploy | Weeks to months (generic patterns) | Weeks, using battle-tested topologies already running elsewhere |
| Post-launch support | In-house operations, SLA depends on staffing | Generic cloud support (not blockchain specific) | 24/7 monitoring, incident response, oracle verification, version upgrades |
