Concepts

The genutil package contains a variaety of genesis utility functionalities 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
  • Genesis file migration
  • CometBFT related initialization
    • Translation of an app genesis to a CometBFT genesis

Client

CLI

The genutil commands are available under the genesis subcommand.

add-genesis-account

Add a genesis account to genesis.json. Learn more here.

collect-gentxs

Collect genesis txs and output a genesis.json file.

simd genesis collect-gentxs

This will create a new genesis.json file that includes data from all the validators (we sometimes call it the "super genesis file" to distinguish it from single-validator genesis files).

gentx

Generate a genesis tx carrying a self delegation.

simd genesis gentx [key_name] [amount] --chain-id [chain-id]

This will create the genesis transaction for your new chain. Here amount should be at least 1000000000stake. If you provide too much or too little, you will encounter an error when starting a node.

migrate

Migrate genesis to a specified target (SDK) version.

simd genesis migrate [target-version]
validate-genesis

Validates the genesis file at the default location or at the location passed as an argument.

simd genesis validate-genesis

Documentation

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
  • Genesis file migration
  • CometBFT related initialization (Translation of an app genesis to a CometBFT genesis)

Functions

func CollectTxs 

func CollectTxs(cdc codec.JSONCodec, txJSONDecoder sdk.TxDecoder, moniker, genTxsDir string,
	genesis *types.AppGenesis, genBalIterator types.GenesisBalancesIterator,
	validator types.MessageValidator,
) (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(genesis *types.AppGenesis, 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 []cmttypes.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, genesis *types.AppGenesis, genBalIterator types.GenesisBalancesIterator,
	validator types.MessageValidator,
) (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)

InitializeNodeValidatorFilesFromMnemonic 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.GenesisOnlyAppModule

NewAppModule creates a new AppModule object

func ProvideModule 

func ProvideModule(in GenutilInputs) appmodule.AppModule

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.
