Published prices, not invoices. Each figure is human-verified against the provider's own pricing page or API and carries the date it was read; the harness re-hashes 23 of those artifacts on a loop to catch an upstream edit. A 30-day month and flat traffic are assumed, the most generous reading. NOWNodes prices in EUR. A provider absent from a cell is not missing data: it has no plan that can serve that workload, usually a cap or a throughput ceiling rather than the price.
BlockMachine and Dwellir are compared on 8 shared OpenChainBench benchmarks. BlockMachine leads on Arbitrum RPC endpoints. Dwellir leads on Ethereum RPC endpoints. See the live table on this page for every metric.
On the Arbitrum RPC endpoints benchmark, BlockMachine leads at 314 ms versus Dwellir at 443 ms. Live measurement is updated continuously by the OpenChainBench harness.
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing; panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
