Chains
Each chain is measured independently. Block heights and slots are different quantities on different scales, so nothing is ever compared across a chain boundary.
- Ethereum9 providers · 12 endpoints · 12000 ms blocksProof-of-stake finality is reached after two justified epochs, roughly 12.8 minutes. Freshness is measured against the latest execution head, which reorgs are expected to affect.
- BSCBNB Smart Chain5 providers · 8 endpoints · 450 ms blocksBNB Smart Chain uses Parlia with fast finality. Sub-second block times mean a single block of lag is normal and is not treated as staleness; the staleness threshold is derived from this block time rather than being a fixed number of blocks.
- Solana3 providers · 5 endpoints · 420 ms blocksSolana slots advance roughly every 400ms, with the observed rate slightly slower because of skipped slots. Commitment levels (processed, confirmed, finalized) mean two healthy providers can legitimately report different heads, so every head is observed at a fixed commitment and compared against the cohort rather than against any single provider.
