func NewApplication

func NewApplication(dbHost, dbName string) *Application

NewApplication method initializes new application with MongoDB state

func (*Application) CheckTx

func (app *Application) CheckTx(txBytes []byte) types.ResponseCheckTx

CheckTx method responsible for check transaction on validity.

func (*Application) Commit
