com.privatechain.core.event.BlockchainEvent

com.privatechain.core.event.BlockchainEvent.ForkDetectedEvent

Enclosing class:

BlockchainEvent

public static final class BlockchainEvent.ForkDetectedEvent
extends BlockchainEvent

Fired when the node detects two competing valid blocks at the same chain height.

The Blockchain resolves forks by applying the longest-chain (greatest cumulative difficulty) rule. This event is published before resolution so that observers can log or alert on the fork. Use getBlockA() and getBlockB() to inspect the competing blocks.

Since:

1.0.0
