Reorg Depth

Reorg depth refers to the number of blocks that are discarded or removed from the blockchain during a reorganization event. A shallow reorg might only involve one or two blocks, which is common and generally harmless.

A deep reorg, however, is a significant event that can cause widespread disruption, including the reversal of many transactions and potential financial loss for users. Measuring reorg depth is a key way to analyze the stability of a chain and detect potential attacks.

It provides a window into the recent history of the network and the level of conflict among miners or validators. It is a vital metric for monitoring the integrity of the ledger in real-time.
