+ * A ChannelMonitor handles chain events (blocks connected and disconnected) and generates
+ * on-chain transactions to ensure no loss of funds occurs.
+ *
+ * You MUST ensure that no ChannelMonitors for a given channel anywhere contain out-of-date
+ * information and are actively monitoring the chain.
+ *
+ * Pending Events or updated HTLCs which have not yet been read out by
+ * get_and_clear_pending_monitor_events or get_and_clear_pending_events are serialized to disk and
+ * reloaded at deserialize-time. Thus, you must ensure that, when handling events, all events
+ * gotten are fully handled before re-serializing the new state.
+ *
+ * Note that the deserializer is only implemented for (BlockHash, ChannelMonitor), which
+ * tells you the last block hash which was block_connect()ed. You MUST rescan any blocks along
+ * the \"reorg path\" (ie disconnecting blocks until you find a common ancestor from both the
+ * returned block hash and the the current chain and then reconnecting blocks to get to the
+ * best chain) upon deserializing the object!
