Ethereum RPC Reliability Research
Data-driven notes on block visibility, stale views, reorg recovery, WebSocket delivery, and the provider behavior real-time Ethereum systems depend on.
Ethereum RPC Redundancy: Coverage, Pair Latency, and Tail Overlap
Two RPC providers can each perform well while sharing the same delivery gaps and latency tails. QuantLoop compares pair coverage, effective event-visibility latency, and P99 tail overlap to identify stronger combinations.
Ethereum RPC Head Replacement Timing: Measuring Provider Recovery at the Chain Tip
When Ethereum's latest block is replaced, real-time systems depend on how quickly their RPC provider corrects the chain-tip view. QuantLoop measures transient view duration, correction lag, and correction lead before the next block height.
99.99% Uptime Does Not Mean 99.99% Data Delivery
RPC endpoints can remain reachable while WebSocket streams go silent, disconnect, or miss live updates. QuantLoop measures delivery completeness and stream continuity.
Measuring Stale Views in Ethereum RPC Infrastructure
An RPC endpoint can be online and responsive while still lagging behind the freshest observed chain view. QuantLoop measures how often providers and regions fall behind by operationally meaningful thresholds.
RPC Latency vs Block Visibility Latency
Fast RPC responses do not guarantee early access to new Ethereum blocks. QuantLoop compares response latency with block visibility to reveal which providers expose new chain state first and which fall behind.
