Functions ¶

func ApplyFromFile ¶

func ApplyFromFile(
	ctx context.Context,
	params ImportParams,
	state State,
	nBlocks, startHeight uint64,
) error

ApplyFromFile reads blocks from blockchainPath, applying them from height startHeight and until nBlocks+1. Setting optimize to true speeds up the import, but it is only safe when importing blockchain from scratch when no rollbacks are possible at all.

func CheckBalances ¶

func CheckBalances(st State, balancesPath string) error
