Types

type Config

type Config struct {
	// Genesis anchor point of the rollup
	Genesis Genesis `json:"genesis"`
	// Seconds per L2 block
	BlockTime uint64 `json:"block_time"`
	// Sequencer batches may not be more than MaxSequencerDrift seconds after
	// the L1 timestamp of the sequencing window end.
	//
	// Note: When L1 has many 1 second consecutive blocks, and L2 grows at fixed 2 seconds,
	// the L2 time may still grow beyond this difference.
	MaxSequencerDrift uint64 `json:"max_sequencer_drift"`
	// Number of epochs (L1 blocks) per sequencing window, including the epoch L1 origin block itself
	SeqWindowSize uint64 `json:"seq_window_size"`
	// Number of L1 blocks between when a channel can be opened and when it must be closed by.
	ChannelTimeout uint64 `json:"channel_timeout"`
	// Required to verify L1 signatures
	L1ChainID *big.Int `json:"l1_chain_id"`
	// Required to identify the L2 network and create p2p signatures unique for this chain.
	L2ChainID *big.Int `json:"l2_chain_id"`

	// L1 address that batches are sent to.
	BatchInboxAddress common.Address `json:"batch_inbox_address"`
	// L1 Deposit Contract Address
	DepositContractAddress common.Address `json:"deposit_contract_address"`
	// L1 System Config Address
	L1SystemConfigAddress common.Address `json:"l1_system_config_address"`
}

func (*Config) Check

func (cfg *Config) Check() error

Check verifies that the given configuration makes sense

func (*Config) L1Signer

func (c *Config) L1Signer() types.Signer

type Epoch

type Epoch uint64

type Genesis

type Genesis struct {
	// The L1 block that the rollup starts *after* (no derived transactions)
	L1 eth.BlockID `json:"l1"`
	// The L2 block the rollup starts from (no transactions, pre-configured state)
	L2 eth.BlockID `json:"l2"`
	// Timestamp of L2 block
	L2Time uint64 `json:"l2_time"`
	// Initial system configuration values.
	// The L2 genesis block may not include transactions, and thus cannot encode the config values,
	// unlike later L2 blocks.
	SystemConfig eth.SystemConfig `json:"system_config"`
}
