What's Changed:
- feat(core): multi-source block ingestion for the bridge listener by @vgonkivs (https://github.com/vgonkivs) in #5018 (https://github.com/celestiaorg/celestia-node/pull/5018)
- feat(metrics): add metrics to improve observability by @vgonkivs (https://github.com/vgonkivs) in #5011 (https://github.com/celestiaorg/celestia-node/pull/5011)
Highlights:
Multi-source block ingestion (#5018) — the bridge listener can now ingest blocks from multiple Celestia-Core endpoints concurrently and tolerate any single one failing:
- new blocks are sourced from all configured endpoints but downloaded once (from the source that announces a height first), with no duplicate fetches;
- per-source sync state and stricter source handling (duplicate endpoints rejected; the node fails fast if the fastest source for a height is on the wrong chain);
- Core.AdditionalCoreEndpoints is now used not only for load-balancing transaction submission but also as additional block sources (config-file only, no CLI flag).
Observability metrics (#5011) — metrics added across key hot paths for diagnostics:
- RPC server (api/rpc), core listener (block events), store, and pruner;
- improved node-info metric reporting.
Action Required (optional):
To enable multi-source ingestion, add the extra endpoints to your bridge node config file:
[Core]
IP = "<primary_ip>"
Port = "<primary_port>"
TLSEnabled = false
XTokenPath = ""
AdditionalCoreEndpoints = [
{ IP = "<secondary_ip>", Port = "<secondary_port>", TLSEnabled = false, XTokenPath = "" },
]
