About QuantLoop

Independent measurement of Ethereum RPC delivery and reliability.

QuantLoop measures how Ethereum blocks and contract events reach real-time systems across RPC providers and regions. It provides an external view of delivery completeness, visibility latency, stale-view exposure, and provider-pair redundancy.

Why it exists

Real-time systems depend on data delivery they do not control

Keepers, liquidators, solvers, trading systems, and risk engines depend on RPC infrastructure to deliver new chain data completely and on time. Provider routing, WebSocket delivery, node behavior, and regional paths can all affect when an update becomes usable.

QuantLoop measures those differences from external observation points: which events arrived, when they became visible, how long stale views persisted, and whether a second provider improved the result.

Independent by design

Measured from the consumer side

QuantLoop is not an RPC provider and does not sell node infrastructure. It measures what downstream systems actually receive from each provider and region.

That perspective reveals failures that uptime and request latency alone do not: missed events, delayed visibility, stale views, and provider pairs whose weaknesses overlap.

Current focus

What QuantLoop measures today

QuantLoop currently focuses on real-time Ethereum RPC delivery for blocks and contract events, measured across providers and observation regions.

Contract-event coverage

Whether each provider and provider pair delivered the monitored contract events.

Event visibility latency

How quickly each event became visible and how much a second provider reduced effective tail latency.

Stale-view exposure

How often an observed delivery path lagged behind the freshest chain view beyond an operational threshold.

Head replacement timing

How quickly providers exposed canonical replacement heads and how long transient views remained visible.

Provider-pair redundancy

How much each pairing improved coverage and latency, and how often both delivery paths entered their tails on the same event.
