How does Kaspa's gossip protocol make sure no valid block gets lost between regions?

Kaspa's gossip protocol is designed so that all viable blocks eventually reach all regions, regardless of where they were mined. When a node hears about a new block, it broadcasts an inventory message to its peers; any peer whose local blue work threshold is met then requests and downloads the full block, and the process repeats outward. Because this happens over parallel paths — many nodes relaying at once rather than a single relay chain — the spread is fast and redundant. For a beginner, this matters because it means a block produced in Asia is not at a disadvantage compared to one produced in North America; the gossip mechanism is what lets Kaspa's blockDAG include parallel blocks rather than discard the ones that arrived a little later.
