Blockchain//Fork

- Temporary forks happen when two validators create competing blocks at the same height due to network latency.

Temporary forks happen when two validators create competing blocks at the same height due to network latency.

Resolution: the chain that gets the next block built on top of it becomes canonical (longest chain rule)

The "losing" block is discarded (becomes an uncle/ommer)

In Clique PoA, this is rare due to turn-based signing — but latency can still cause brief bifurcations.
