Primary Network runs the Snowman BFT consensus derived from Snow protocols. Sub-second deterministic finality with no chain reorganizations.
Side by side measurements
How this pair was selected
A pair is published when all four conditions hold. Both providers run in the same OpenChainBench benchmark for at least seven consecutive days. Each provider has at least 1000 samples in the measurement window. The head to head query has observable third party search demand. Both providers have a public /products/[slug] page on OCB. The full pair ledger is versioned in the public repo so the methodology is externally verifiable.
