New App Initiation

Source code reference location

When the Cosmos SDK AddCommands method was called with the Akash initRootCmd function - included anew below for ease of reference - the newApp function is passed in as an argument.

func initRootCmd(rootCmd *cobra.Command, encodingConfig params.EncodingConfig) {
    ....

    server.AddCommands(rootCmd, app.DefaultHome, newApp, createAppAndExport, addModuleInitFlags)

    ....
}

The newApp function calls the NewApp method located in node/app/app.go. The NewApp method initiates and defines the base parameters of the blockchain.

func newApp(logger log.Logger, db dbm.DB, traceStore io.Writer, appOpts servertypes.AppOptions) servertypes.Application {
    ...

    return app.NewApp(
        logger, db, traceStore, true, cast.ToUint(appOpts.Get(server.FlagInvCheckPeriod)), skipUpgradeHeights,
        cast.ToString(appOpts.Get(flags.FlagHome)),
        appOpts,
        baseapp.SetPruning(pruningOpts),
        baseapp.SetMinGasPrices(cast.ToString(appOpts.Get(server.FlagMinGasPrices))),
        baseapp.SetHaltHeight(cast.ToUint64(appOpts.Get(server.FlagHaltHeight))),
        baseapp.SetHaltTime(cast.ToUint64(appOpts.Get(server.FlagHaltTime))),
        baseapp.SetMinRetainBlocks(cast.ToUint64(appOpts.Get(server.FlagMinRetainBlocks))),
        baseapp.SetInterBlockCache(cache),
        baseapp.SetTrace(cast.ToBool(appOpts.Get(server.FlagTrace))),
        baseapp.SetIndexEvents(cast.ToStringSlice(appOpts.Get(server.FlagIndexEvents))),
        baseapp.SetSnapshotStore(snapshotStore),
        baseapp.SetSnapshotInterval(cast.ToUint64(appOpts.Get(server.FlagStateSyncSnapshotInterval))),
        baseapp.SetSnapshotKeepRecent(cast.ToUint32(appOpts.Get(server.FlagStateSyncSnapshotKeepRecent))),
    )
}
