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.

01

Validators

Proof-of-stake consensus nodes that propose and attest blocks, earn staking rewards, and secure the network.
02

Full & archive nodes

Store current state (full) or the complete chain history (archive); feed explorers, indexers, and analytics tools.
03

RPC endpoints

The public API layer wallets and dApps call to read on-chain state and broadcast transactions.
04

Block explorer

The human-readable transaction, address, and contract view developers use to debug and verify on-chain activity.
05

Indexing & subgraphs

Queryable, low-latency on-chain data layer that application backends and analytics tools depend on.
06

Monitoring & analytics

Request volumes, error rates, latency percentiles, and per-endpoint demand that make reliability measurable rather than assumed.
01

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.

How an engagement works

1

Assessment

We map your infrastructure topology, throughput and reliability targets, and network/client requirements, then advise on effective adjustments. Deliverable: an infra-readiness review.
2

Architecture & prototyping

We design the topology and, where useful, share a ready-made similar deployment so you can validate the approach before committing.
3

Deployment

We build and ship the infrastructure, nodes, RPC, explorers, and indexing, with automated pipelines and containerization, on your schedule and budget.
4

Network bootstrapping

We validate client and network-specific requirements (RPC, explorer, DNS, wallets, protocol quirks) and bring the stack into production.
5

Monitoring configuration

We wire up observability, usage analytics, and alerting so reliability is measurable from the first day of traffic.
6

Operate, support & tune

Ongoing maintenance, incident response, and SLA-oriented operations, we flag you only when a decision is genuinely needed.

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.

Production infrastructure, measured
99.95%+RPC uptime, 30,000+ monthly developers, 4B+ node requests/month

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.

FAQ

What is blockchain infrastructure?
Blockchain infrastructure is the production operational layer of a network (the validator and full nodes, RPC and API endpoints, block explorers, indexers, oracles, and the monitoring around them) that lets developers and users actually interact with the chain. It is distinct from the smart contracts and applications built on top: infrastructure is what keeps those applications reachable, fast, and reliable, and when it fails the whole ecosystem feels it. The work spans deploying and operating nodes, load-balancing and caching public RPC, standing up an explorer and indexing layer, and instrumenting everything with observability so reliability is measurable rather than a matter of luck. At Protofire it is run by a dedicated DevOps and SRE team that has operated this layer in production since 2016, across 60+ networks and as a Filecoin infrastructure partner since 2021.
What's the difference between a validator node, full node, and archival node?
A full node stores the current state and recent blocks, independently validates transactions and blocks against the network's consensus rules, and serves data to applications, but it prunes older historical state to save disk. An archival node is a full node that keeps the entire historical state of the chain, so it can answer queries about balances or contract storage at any past block; it needs far more storage and is what most indexers, explorers, and analytics tools depend on. A validator node participates in consensus by proposing and attesting to blocks and, on proof-of-stake networks, staking tokens to earn rewards and help secure the chain. A single machine can play more than one of these roles at once. At Protofire we operate all three in production across 60+ networks: hardened validator nodes for chains and stakers, and archival nodes that feed our explorers and subgraph indexing.
What is an RPC node?
An RPC node is a node that exposes a chain's data and transaction-submission methods over a Remote Procedure Call API, typically JSON-RPC over HTTPS or WebSocket. It is the endpoint wallets, dApps, and backends call to read on-chain state and broadcast transactions: effectively the front door every developer walks through to talk to a network. Because all that traffic funnels through it, a public RPC has to be load-balanced, cached, and continuously monitored to stay fast and reliable under real load. Running RPC well is a mindset rather than a single server, with accessible APIs, community feedback loops, and continuous tuning. We operate 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, with one-line integration so consumers can swap endpoints without touching their stack.
Should we use managed nodes or self-host?
You can run your own nodes, but running them reliably under real traffic, with load balancing, caching, usage analytics, monitoring, and SLA-style incident response, is a different capability than simply starting a node. Self-hosting is reasonable early on; managed infrastructure starts to make sense once uptime and reliability become strategic, when there is real developer or user traffic to justify it, or when you would rather your core team stay focused on the chain itself than staff a full SRE function. We handle the operational work end to end: deploying full, light, and archival nodes and high-performance RPC, instrumenting each deployment with observability and usage analytics from day one, and running incident response. We do much of it on optimized and bare-metal hardware, so run-cost stays predictable as usage grows rather than arriving as a surprise cloud invoice.
Which networks and node types do you support?
EVM L1/L2 chains and ecosystem foundations are our core. We deploy and operate full, light, and archival nodes, validators, RPC and API endpoints, indexers and subgraphs, and block explorers, and our engineers also run miners, witnesses, relayers, fishermen, and sentinels where a network needs them. We have operated infrastructure across 60+ networks, including Filecoin (where we have been an infrastructure partner since 2021), Avalanche, Fuse, Meter, CrossFi, Stratos, DFK, Secret Network, Lava Network, and Fluence, plus Filecoin/IPC-style storage and appchain contexts. A single machine can play more than one of these roles at once, and we validate the client- and network-specific requirements (RPC, explorer, DNS, wallet, and protocol quirks) before bringing the stack into production. Deployments typically go live in a few weeks, not quarters, because we start from topologies we already run elsewhere.
As a chain or foundation, can you run our public RPC and validators as an ecosystem primitive?
Yes, this is a primary use case. We operate node, RPC, explorer, and indexing infrastructure as a managed ecosystem primitive for chains and foundations, so your builders get reliable tooling and you close the gap against competitor chains without diverting your core team from protocol work. In practice that means professionalized operations (better reliability metrics, usage analytics, and a trusted node-operator partner) delivered as a dedicated, SLA-oriented operations partnership rather than a one-off install. It is exactly what we run for Filecoin, now a network handling 4+ billion node requests a month, where disciplined monitoring and node tuning pushed Glif-managed RPC uptime to 99.95%+ and lifted developer usage 240% to 30,000+ monthly developers. We instrument everything from day one with our own Proteus Shield tooling for usage analytics, billing, caching, and monitoring, so scaling stays a measured decision rather than a surprise.
How much does blockchain infrastructure cost?
Blockchain infrastructure is a recurring, usage-driven operations model rather than a flat one-time fee, because cost scales with traffic volume, the node types you need, and the coverage level (standard, full-time, or extended). We don't quote a number blind: foundational monitoring and analytics are scoped up front, and a full ecosystem-primitive partnership (validators, RPC, explorer, and indexing operated as managed infrastructure) is sized on the first call against your throughput and reliability targets. Because we run much of the stack on optimized and bare-metal hardware rather than blindly on managed cloud, run-cost stays predictable as usage grows instead of arriving as a surprise invoice, and our Proteus Shield tooling gives you usage analytics and billing visibility so capacity and cost decisions are data-driven. We size the engagement before any work starts, so there are no open-ended commitments.
