Functions

func ExportChainN

func ExportChainN(blockchain *core.BlockChain, fn string, first, last uint64) error

ExportChain exports a blockchain into the specified file, truncating any data already present in the file.

func ExportPreimages

func ExportPreimages(db *database.LDBDatabase, fn string) error

ExportPreimages exports all known hash preimages into the specified file, truncating any data already present in the file.

func Fatalf

func Fatalf(format string, args ...interface{})

Fatalf formats a message to standard error and exits the program. The message is also printed to standard output if standard error is redirected to a different file.

func ImportChain

func ImportChain(chain *core.BlockChain, fn string) error

func ImportPreimages

func ImportPreimages(db *database.LDBDatabase, fn string) error

ImportPreimages imports a batch of exported hash preimages into the database.

func MakeChainDatabase

func MakeChainDatabase(ctx *cli.Context, n *node.Node, databaseCache int) database.Database

MakeChainDatabase open an LevelDB using the flags passed to the client and will hard crash if it fails. It creates a new one if the database doesn't exist.

func MakeGenesis

func MakeGenesis(ctx *cli.Context) *core.Genesis

MakeGenesis builds a genesis block object.

func OpenChain

func OpenChain(ctx *cli.Context, n *node.Node, cfg *cpc.Config) (chain *core.BlockChain, chainDb database.Database)

OpenChain opens a blockchain

func ReadPassword

func ReadPassword(prompt string, needConfirm bool) (string, error)
