Concepts

The genutil package contains a variety 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 creation
  • Genesis file validation
  • Genesis file migration
  • CometBFT related initialization
    • Translation of an app genesis to a CometBFT genesis

Genesis

Genutil contains the data structure that defines an application genesis. An application genesis consist of a consensus genesis (g.e. CometBFT genesis) and application related genesis data.

https://github.com/cosmos/cosmos-sdk/blob/v0.50.0-rc.0/x/genutil/types/genesis.go#L24-L34

The application genesis can then be translated to the consensus engine to the right format:

https://github.com/cosmos/cosmos-sdk/blob/v0.50.0-rc.0/x/genutil/types/genesis.go#L126-L136

https://github.com/cosmos/cosmos-sdk/blob/v0.50.0-rc.0/server/start.go#L397-L407

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]

:::tip The migrate command is extensible and takes a MigrationMap. This map is a mapping of target versions to genesis migrations functions. When not using the default MigrationMap, it is recommended to still call the default MigrationMap corresponding the SDK version of the chain and prepend/append your own genesis migrations. :::

validate-genesis

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

simd genesis validate-genesis

:::warning Validate genesis only validates if the genesis is valid at the current application binary. For validating a genesis from a previous version of the application, use the migrate command to migrate the genesis to the current version. :::

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 AddGenesisAccount 

func AddGenesisAccount(
	cdc codec.Codec,
	accAddr sdk.AccAddress,
	appendAcct bool,
	genesisFileURL, amountStr, vestingAmtStr string,
	vestingStart, vestingEnd int64,
	moduleName string,
) error

AddGenesisAccount adds a genesis account to the genesis state. Where `cdc` is client codec, `genesisFileUrl` is the path/url of current genesis file, `accAddr` is the address to be added to the genesis state, `amountStr` is the list of initial coins to be added for the account, `appendAcct` updates the account if already exists. `vestingStart, vestingEnd and vestingAmtStr` respectively are the schedule start time, end time (unix epoch) `moduleName“ is the module name for which the account is being created and coins to be appended to the account already in the genesis.json file.

func CollectTxs 

func CollectTxs(cdc codec.JSONCodec, txJSONDecoder sdk.TxDecoder, moniker, genTxsDir string,
	genesis *types.AppGenesis, genBalIterator types.GenesisBalancesIterator,
	validator types.MessageValidator, valAddrCodec sdkruntime.ValidatorAddressCodec,
) (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 genesis.TxHandler,
	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, valAddrCodec sdkruntime.ValidatorAddressCodec,
) (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 genesis.TxHandler, 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)
