Network Recovery
Pronunciation: NET-wurk ree-KUV-er-ee
Definition
Network recovery describes restoring useful blockchain or payment-network operation after an outage, partition, degraded node service or other disruption.
Overview
What it means
Network recovery describes restoring useful blockchain or payment-network operation after an outage, partition, degraded node service or other disruption. The term may refer to a node catching up, a service failing over, or protocol-level restoration.
How it works
Operators identify whether the problem affects local connectivity, RPC providers, indexers, consensus participation or the chain itself. They restore dependencies, resynchronize data from trustworthy checkpoints and verify missed transaction intervals. Payment systems should keep submission attempts distinct from confirmed outcomes during the incident.
Understanding the technical details
Separate infrastructure health from chain health. A failing RPC provider can be replaced without any consensus problem, whereas a halted chain may affect every honest provider simultaneously. After recovery, rescan all missing block ranges, verify block continuity and reconcile payouts started near the outage. An incident postmortem should include which invoices were uncertain and how each was resolved. Automatic failover is valuable only if the secondary data source is independently trustworthy.
Additional protocol context
Returning an endpoint to service is only one step. Operators must verify canonical state, synchronization, finality, pending transactions, wallet balances, indexer completeness, and any missed cross-chain messages. Unsafe shortcuts can create duplicate processing or divergent histories.
Recovery plans should define authority, checkpoints, rollback constraints, staged validation, and user communication. Payment providers need transaction reconciliation before reopening deposits or withdrawals. Post-incident reviews should address the initiating fault and any control that failed to contain it.
Common failures and limitations
Failing over to another API does not repair a stalled blockchain consensus. Blindly resending payout transactions after a communications outage can double-execute instructions. Incident logs and customer status messages should state what is unknown.

Example
A store loses access to its primary blockchain RPC provider. It switches to a secondary endpoint, verifies recent block hashes and scans the missing interval before releasing orders whose payment status is now supported by evidence.
Comparison
Network recovery restores availability and trustworthy chain data; payment state recovery reconciles invoices; disaster recovery restores broader infrastructure and business operations after a major incident.
Key Takeaway
Failing over to another API does not repair a stalled blockchain consensus.
