Types

type Config

type Config struct {
	// This define is a trusted node (`true`) or a permission less (`false`). If you don't known
	// set to `false`
	IsTrustedSequencer bool `mapstructure:"IsTrustedSequencer"`
	// Last batch number before  a forkid change (fork upgrade). That implies that
	// greater batch numbers are going to be trusted but no virtualized neither verified.
	// So after the batch number `ForkUpgradeBatchNumber` is virtualized and verified you could update
	// the system (SC,...) to new forkId and remove this value to allow the system to keep
	// Virtualizing and verifying the new batchs.
	// Check issue [#2236](https://github.com/0xPolygonHermez/zkevm-node/issues/2236) to known more
	// This value overwrite `SequenceSender.ForkUpgradeBatchNumber`
	ForkUpgradeBatchNumber uint64 `mapstructure:"ForkUpgradeBatchNumber"`
	// Which is the new forkId
	ForkUpgradeNewForkId uint64 `mapstructure:"ForkUpgradeNewForkId"`
	// Configure Log level for all the services, allow also to store the logs in a file
	Log log.Config
	// Configuration of the etherman (client for access L1)
	Etherman etherman.Config
	// Configuration for ethereum transaction manager
	EthTxManager ethtxmanager.Config
	// Pool service configuration
	Pool pool.Config
	// Configuration for RPC service. THis one offers a extended Ethereum JSON-RPC API interface to interact with the node
	RPC jsonrpc.Config
	// Configuration of service `Syncrhonizer`. For this service is also really important the value of `IsTrustedSequencer`
	// because depending of this values is going to ask to a trusted node for trusted transactions or not
	Synchronizer synchronizer.Config
	// Configuration of the sequencer service
	Sequencer sequencer.Config
	// Configuration of the sequence sender service
	SequenceSender sequencesender.Config
	// Configuration of the aggregator service
	Aggregator aggregator.Config
	// Configuration of the genesis of the network. This is used to known the initial state of the network
	NetworkConfig NetworkConfig
	// Configuration of the gas price suggester service
	L2GasPriceSuggester gasprice.Config
	// Configuration of the executor service
	Executor executor.Config
	// Configuration of the merkle tree client service. Not use in the node, only for testing
	MTClient merkletree.Config
	// Configuration of the state database connection
	StateDB db.Config
	// Configuration of the metrics service, basically is where is going to publish the metrics
	Metrics metrics.Config
	// Configuration of the event database connection
	EventLog event.Config
	// Configuration of the hash database connection
	HashDB db.Config
}

Config represents the configuration of the entire Hermez Node The file is TOML format You could find some examples:

• `config/environments/local/local.node.config.toml`: running a permisionless node
• `config/environments/mainnet/node.config.toml`
• `config/environments/public/node.config.toml`
• `test/config/test.node.config.toml`: configuration for a trusted node used in CI

func Default

func Default() (*Config, error)

Default parses the default configuration values.

func Load

func Load(ctx *cli.Context, loadNetworkConfig bool) (*Config, error)

Load loads the configuration

type ConfigJsonSchemaGenerater

type ConfigJsonSchemaGenerater[T any] struct {
	// contains filtered or unexported fields
}

ConfigJsonSchemaGenerater are the parameters to generate a json-schema based on the T struct The parametrization of the function are used for unittest

func NewNetworkConfigJsonSchemaGenerater

func NewNetworkConfigJsonSchemaGenerater() ConfigJsonSchemaGenerater[GenesisFromJSON]

NewNetworkConfigJsonSchemaGenerater returns a new class for generating json-schema of the network-custom config file (.json)

func NewNodeConfigJsonSchemaGenerater

func NewNodeConfigJsonSchemaGenerater() ConfigJsonSchemaGenerater[Config]

NewNodeConfigJsonSchemaGenerater returns a new class for generating json-schema of the node config file (.toml)

func (ConfigJsonSchemaGenerater[T]) GenerateJsonSchema

func (s ConfigJsonSchemaGenerater[T]) GenerateJsonSchema(cli *cli.Context) (*jsonschema.Schema, error)

GenerateJsonSchema launchs the generation, and returns the schema

func (ConfigJsonSchemaGenerater[T]) GenerateJsonSchemaAndWriteToFile

func (s ConfigJsonSchemaGenerater[T]) GenerateJsonSchemaAndWriteToFile(cli *cli.Context, output_filename string) error

GenerateJsonSchemaAndWriteToFile generate the schema and store in `output_filename` file

func (ConfigJsonSchemaGenerater[T]) SerializeJsonSchema

func (s ConfigJsonSchemaGenerater[T]) SerializeJsonSchema(schema *jsonschema.Schema) ([]byte, error)

SerializeJsonSchema serializes the schema in JSON to be stored

type GenesisFromJSON

type GenesisFromJSON struct {
	// L1: root hash of the genesis block
	Root string `json:"root"`
	// L1: block number of the genesis block
	GenesisBlockNum uint64 `json:"genesisBlockNumber"`
	// L2:  List of states contracts used to populate merkle tree at initial state
	Genesis []genesisAccountFromJSON `json:"genesis"`
	// L1: configuration of the network
	L1Config etherman.L1Config
}

GenesisFromJSON is the config file for network_custom

type NetworkConfig

type NetworkConfig struct {
	// L1: Configuration related to L1
	L1Config etherman.L1Config `json:"l1Config"`
	// DEPRECATED L2: address of the `PolygonZkEVMGlobalExitRootL2 proxy` smart contract
	L2GlobalExitRootManagerAddr common.Address
	// L2: address of the `PolygonZkEVMBridge proxy` smart contract
	L2BridgeAddr common.Address
	// L1: Genesis of the rollup, first block number and root
	Genesis state.Genesis
}

NetworkConfig is the configuration struct for the different environments
