Overview

Package genutil contains a variety of genesis utility functionality for usage within a blockchain application. Namely:

• Genesis transactions related (gentx)
• commands for collection and creation of gentxs
• initchain processing of gentxs
• Genesis file validation
• Tendermint related initialization

Functions

func CollectTxs

func CollectTxs(cdc codec.JSONCodec, txJSONDecoder sdk.TxDecoder, moniker, genTxsDir string,
	genDoc tmtypes.GenesisDoc, genBalIterator types.GenesisBalancesIterator,
) (appGenTxs []sdk.Tx, persistentPeers string, err error)

CollectTxs processes and validates application's genesis Txs and returns the list of appGenTxs, and persistent peers required to generate genesis.json.

func DeliverGenTxs

func DeliverGenTxs(
	ctx sdk.Context, genTxs []json.RawMessage,
	stakingKeeper types.StakingKeeper, deliverTx deliverTxfn,
	txEncodingConfig client.TxEncodingConfig,
) ([]abci.ValidatorUpdate, error)

DeliverGenTxs iterates over all genesis txs, decodes each into a Tx and invokes the provided deliverTxfn with the decoded Tx. It returns the result of the staking module's ApplyAndReturnValidatorSetUpdates.

func ExportGenesisFile

func ExportGenesisFile(genDoc *tmtypes.GenesisDoc, genFile string) error

ExportGenesisFile creates and writes the genesis configuration to disk. An error is returned if building or writing the configuration to file fails.

func ExportGenesisFileWithTime

func ExportGenesisFileWithTime(
	genFile, chainID string, validators []tmtypes.GenesisValidator,
	appState json.RawMessage, genTime time.Time,
) error

ExportGenesisFileWithTime creates and writes the genesis configuration to disk. An error is returned if building or writing the configuration to file fails.

func GenAppStateFromConfig

func GenAppStateFromConfig(cdc codec.JSONCodec, txEncodingConfig client.TxEncodingConfig,
	config *cfg.Config, initCfg types.InitConfig, genDoc tmtypes.GenesisDoc, genBalIterator types.GenesisBalancesIterator,
) (appState json.RawMessage, err error)

GenAppStateFromConfig gets the genesis app state from the config

func InitGenesis

func InitGenesis(
	ctx sdk.Context, stakingKeeper types.StakingKeeper,
	deliverTx deliverTxfn, genesisState types.GenesisState,
	txEncodingConfig client.TxEncodingConfig,
) (validators []abci.ValidatorUpdate, err error)

InitGenesis - initialize accounts and deliver genesis transactions

func InitializeNodeValidatorFiles

func InitializeNodeValidatorFiles(config *cfg.Config) (nodeID string, valPubKey cryptotypes.PubKey, err error)

InitializeNodeValidatorFiles creates private validator and p2p configuration files.

func InitializeNodeValidatorFilesFromMnemonic

func InitializeNodeValidatorFilesFromMnemonic(config *cfg.Config, mnemonic string) (nodeID string, valPubKey cryptotypes.PubKey, err error)

InitializeNodeValidatorFiles creates private validator and p2p configuration files using the given mnemonic. If no valid mnemonic is given, a random one will be used instead.

func NewAppModule

func NewAppModule(accountKeeper types.AccountKeeper,
	stakingKeeper types.StakingKeeper, deliverTx deliverTxfn,
	txEncodingConfig client.TxEncodingConfig,
) module.AppModule

NewAppModule creates a new AppModule object

func SetGenTxsInAppGenesisState

func SetGenTxsInAppGenesisState(
	cdc codec.JSONCodec, txJSONEncoder sdk.TxEncoder, appGenesisState map[string]json.RawMessage, genTxs []sdk.Tx,
) (map[string]json.RawMessage, error)

SetGenTxsInAppGenesisState - sets the genesis transactions in the app genesis state

func ValidateAccountInGenesis

func ValidateAccountInGenesis(
	appGenesisState map[string]json.RawMessage, genBalIterator types.GenesisBalancesIterator,
	addr sdk.Address, coins sdk.Coins, cdc codec.JSONCodec,
) error

ValidateAccountInGenesis checks that the provided account has a sufficient balance in the set of genesis accounts.
