Blockchain Indexer Hosting on Offshore Dedicated Servers

A typical blockchain indexer combines a Postgres database (often with TimescaleDB extensions for time-series data), an indexing engine (graph-node, Subsquid, Ponder, or custom), an Ethereum RPC node for source data, and a public-facing GraphQL or REST API endpoint. Each component has its own resource profile, but the dominant resource is database I/O: indexers do millions of inserts and updates as they process historical chain data.

AnubizHost blockchain-tier dedicated servers ship with 64 GB to 128 GB of RAM, 16 to 32 CPU cores and 2 TB to 8 TB of NVMe RAID storage. This is sized appropriately for serious indexer workloads, including initial historical sync (which can take days for chains like Ethereum) and ongoing live indexing. The PostgreSQL workload benefits enormously from dedicated NVMe storage and ample shared_buffers allocations that our memory sizing enables.

Co-locating an Ethereum or other-chain RPC node on the same chassis eliminates the dependence on third-party RPC providers and dramatically reduces sync latency. For high-throughput indexers (Subsquid in particular benefits from this), we can scope dual-server packages with the RPC node on one host and the indexer on another, connected via private 10 Gbps interconnect.

Initial indexer sync is the most demanding workload an indexer faces. Processing the full history of a chain like Ethereum or Polygon requires hours to days of sustained high-throughput RPC reads, database inserts and CPU-bound mapping logic. Our hardware sustains this sustained load without thermal throttling or storage degradation, which is critical for operators rebuilding indexers after schema changes or chain reorgs.

Once an indexer is live and following the chain head, the workload shifts to incremental block processing plus serving GraphQL or REST API queries from users. Query throughput depends heavily on database tuning and the underlying NVMe storage performance. Our hardware sustains thousands of complex GraphQL queries per second on a well-tuned indexer with appropriate PostgreSQL indexes.

Bandwidth matters for indexers serving public GraphQL APIs: a popular indexer can push terabytes of egress per month responding to API queries. Our unmetered 1 Gbps uplinks (or 10 Gbps upgrades) eliminate the bandwidth overage risk that affects indexers hosted on metered cloud providers.

Indexer operators provide critical infrastructure for the dapp ecosystem, but they increasingly face questions about the regulatory classification of their services. Hosting in Iceland or Romania, paying in crypto and operating without KYC at the hosting layer keeps your indexer operation outside the regulatory pressure zones forming in major markets. Neither jurisdiction has classified indexer operation as a regulated financial activity.

AnubizHost billing supports ETH, BTC, XMR, GRT, USDC, USDT and other major coins through Plisio and NowPayments. Indexer operators can pay invoices directly from operator wallets or DAO treasuries without converting to fiat. No card processors, no fiat conversion, no identity verification beyond a working email. Renewal invoices are issued seven days before service expiry.

For operators building paid indexer services or running multiple indexers across chains, we can scope multi-server packages with bulk pricing and unified provisioning. Onboarding takes minutes from order to first sync, with full operator control over indexer configuration, database tuning and API endpoint management at all times.
