## types.go
-`Monitor_context`: monitor context is an object that contains all the configuration and storage information about the monitor
- `methods`: internal methods defined in this file includes savestorage, loadstorage, getobject, isduplicate, and storeobject

  this function will send the raw version of the gossip object to the gossiper, wait for gossip_wait_time, check updated local PoM database,  
  if there is no PoM against the signer of this sth/revocation information, threshold sign this sth/revocation information and send it to the gossiper
