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 seconds (w.r.t. L1 time) that a frame can be valid when included in L1
	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"`

	// Address of the key the sequencer uses to sign blocks on the P2P layer
	P2PSequencerAddress common.Address `json:"p2p_sequencer_address"`

	// L2 address used to send all priority fees to, also known as the coinbase address in the block.
	FeeRecipientAddress common.Address `json:"fee_recipient_address"`
	// L1 address that batches are sent to.
	BatchInboxAddress common.Address `json:"batch_inbox_address"`
	// Acceptable batch-sender address
	BatchSenderAddress common.Address `json:"batch_sender_address"`
	// L1 Deposit Contract Address
	DepositContractAddress common.Address `json:"deposit_contract_address"`
}

type Genesis

type Genesis struct {
	// The L1 block that the rollup starts *after* (no derived transactions)
