OpenScan.AI runs a set of background workers alongside the core indexer and API. They handle the work that doesn’t belong on the request path: aggregating statistics, routing custom domains, and periodic housekeeping.
The Background Services
Statistics Worker
Aggregates chain metrics — daily transactions, active addresses, gas trends — into rollup tables that power charts and homepage stats.
Custom Domain Service
Manages custom-domain routing and certificates so your explorer answers on your own domain.
Housekeeping Worker
Periodic maintenance: expiring stale caches, pruning temporary data, and consistency checks.
Operating Notes
- Background workers are safe to restart at any time; they resume from persisted checkpoints.
- If the statistics worker falls behind, charts show stale aggregates but core explorer pages are unaffected.
- Watch worker logs during upgrades — schema changes land first, then workers are restarted.
