Field notes on running DePIN infrastructure at scale: validator operations, GPU inference, decentralized storage, and Web3 DevOps. No fluff — just what we ship, what breaks, and what we learn fixing it.

Case study: incentivized testnet, 50-node burst in 72h, top-5 operator
Anonymized case study: a burst engagement for an incentivized testnet. 50 nodes in 72h, finished top-5 by uptime. And the hidden AWS quota that almost killed the first 24 hours.

Case study: DePIN sub-operator, 200 nodes across 8 regions, 99.94% uptime
Anonymized case study: ongoing operations for a DePIN sub-operator. 200 nodes across 8 regions, 99.94% uptime, and a 28-hour DNS-cache incident that ate 1.8% of reward.

Case study: vLLM inference across 3 regions, -60% cost per token
Anonymized case: an LLM startup, 4 months on inference infrastructure. -60% cost/token, p99 latency unchanged. And a 36-hour hunt for the missing 30% throughput.

Case study: ZK rollup, 6 months of validator ops, slashing: 0
Anonymized case study: validator ops + prover farm for a ZK rollup. 6 months in production, zero slashing, and a 48-hour incident where proof ETA drifted.

Cloud vs bare metal for L1 validators, mid-2025
By mid-2025 bare metal beats cloud on every axis that actually matters for an L1 validator, except one. Here are the numbers from our fleet and why we still keep some nodes in the cloud anyway.

Why we publish our node inventory
Transparency is rare in node operations. Here's why we made our full 85-node inventory public and what it changes for clients.
