  11  * A ChannelMonitor handles chain events (blocks connected and disconnected) and generates
  12  * on-chain transactions to ensure no loss of funds occurs.
  13  *
  14  * You MUST ensure that no ChannelMonitors for a given channel anywhere contain out-of-date
  15  * information and are actively monitoring the chain.
  16  *
  17  * Pending Events or updated HTLCs which have not yet been read out by
  18  * get_and_clear_pending_monitor_events or get_and_clear_pending_events are serialized to disk and
  19  * reloaded at deserialize-time. Thus, you must ensure that, when handling events, all events
  20  * gotten are fully handled before re-serializing the new state.
  21  *
  22  * Note that the deserializer is only implemented for (BlockHash, ChannelMonitor), which
  23  * tells you the last block hash which was block_connect()ed. You MUST rescan any blocks along
  24  * the \"reorg path\" (ie disconnecting blocks until you find a common ancestor from both the
  25  * returned block hash and the the current chain and then reconnecting blocks to get to the
  26  * best chain) upon deserializing the object!
