86d8505 Refactor CActiveMasternode + move strMasterNodeAddr to CActiveMasternode a005c79 Refactor InstantSend + new lock cs_instantsend to protect maps on CleanTransactionLocksList() + new DEFAULT_INSTANTSEND_DEPTH constant + rename MIN_INSTANTX_PROTO_VERSION to MIN_INSTANTSEND_PROTO_VERSION and bump it d24182c Refactor Privatesend + decouple from util.h and version.h + more functions for CDarksendBroadcastTx: constructors, signing, serialization + move from rand() to insecure_rand() in general but to GetRand() for session id + fix defaults
