Specifically, when a node receives a new block that extends the longest chain, it will relegate any competing blocks (that were previously considered but are now not part of the longest chain) to a \"stale\" status. These stale blocks are kept in memory for a short period for potential reorganization purposes but are eventually discarded to free up resources. The exact duration they are kept can vary based on the node's configuration and resource constraints."}
