Handling of Transactions After Network Partition
From what I understand, during a network partition, such as an island 🏝️ temporarily becoming ❌ isolated from the rest of the network, local miners continue producing blocks that reference only the blocks they can see. When connectivity is restored, the global DAG merges both views, and the GhostDAG protocol recalculates the blue 🟦 and red 🟥 sets — with the globally heavier side dominating. The “island” blocks then **become red because they were created in isolation**. 1. What happens to the transactions in those red blocks? If we ignore double spending for a moment, these transactions are at least unconfirmed, right? 1. What would a typical merchant wallet do in such a case - does it automatically rebroadcast transactions that ended up in red blocks? 1. Is there any time limit on how long a partition can last before rebroadcasting is no longer possible (again, assuming no double-spend conflict)?
