Network Split Recovery

Network split recovery is the process by which a distributed system heals itself after a temporary partition, reconciling conflicting transaction histories. When a network splits, different segments may continue to process transactions independently, leading to divergent states.

Once communication is restored, the protocol must determine which version of the truth is valid, usually based on rules like the longest chain or specific checkpointing mechanisms. In financial applications, this is a high-risk event because it could result in the invalidation of trades that occurred during the split.

Recovery must be handled automatically and transparently to prevent user confusion and loss of funds. This process tests the resilience of the protocol's consensus rules and its ability to handle asynchronous data streams.
