Types

type Aggregator

type Aggregator struct {
	pb.UnimplementedAggregatorServiceServer

	State                   stateInterface
	EthTxManager            ethTxManager
	Ethman                  etherman
	ProfitabilityChecker    aggregatorTxProfitabilityChecker
	TimeSendFinalProof      time.Time
	StateDBMutex            *sync.Mutex
	TimeSendFinalProofMutex *sync.RWMutex
	// contains filtered or unexported fields
}

Aggregator represents an aggregator

func New

func New(
	cfg Config,
	stateInterface stateInterface,
	ethTxManager ethTxManager,
	etherman etherman,
) (Aggregator, error)

New creates a new aggregator.

func (*Aggregator) Channel

func (a *Aggregator) Channel(stream pb.AggregatorService_ChannelServer) error

Channel implements the bi-directional communication channel between the Prover client and the Aggregator server.

func (*Aggregator) Start

func (a *Aggregator) Start(ctx context.Context) error

Start starts the aggregator

func (*Aggregator) Stop

func (a *Aggregator) Stop()

Stop stops the Aggregator server.

type Config

type Config struct {
	// Host for the grpc server
	Host string `mapstructure:"Host"`
	// Port for the grpc server
	Port int `mapstructure:"Port"`

	// RetryTime is the time the aggregator main loop sleeps if there are no proofs to aggregate
	// or batches to generate proofs. It is also used in the isSynced loop
	RetryTime types.Duration `mapstructure:"RetryTime"`

	// VerifyProofInterval is the interval of time to verify/send an proof in L1
	VerifyProofInterval types.Duration `mapstructure:"VerifyProofInterval"`

	// ProofStatePollingInterval is the interval time to polling the prover about the generation state of a proof
	ProofStatePollingInterval types.Duration `mapstructure:"ProofStatePollingInterval"`

	// TxProfitabilityCheckerType type for checking is it profitable for aggregator to validate batch
	// possible values: base/acceptall
	TxProfitabilityCheckerType TxProfitabilityCheckerType `mapstructure:"TxProfitabilityCheckerType"`

	// TxProfitabilityMinReward min reward for base tx profitability checker when aggregator will validate batch
	// this parameter is used for the base tx profitability checker
	TxProfitabilityMinReward TokenAmountWithDecimals `mapstructure:"TxProfitabilityMinReward"`

	// IntervalAfterWhichBatchConsolidateAnyway this is interval for the main sequencer, that will check if there is no transactions
	IntervalAfterWhichBatchConsolidateAnyway types.Duration `mapstructure:"IntervalAfterWhichBatchConsolidateAnyway"`

	// ChainID is the L2 ChainID provided by the Network Config
	ChainID uint64

	// SenderAddress defines which private key the eth tx manager needs to use
	// to sign the L1 txs
	SenderAddress string `mapstructure:"SenderAddress"`
}

Config represents the configuration of the aggregator

type TokenAmountWithDecimals

type TokenAmountWithDecimals struct {
	*big.Int `validate:"required"`
}

TokenAmountWithDecimals is a wrapper type that parses token amount with decimals to big int

func (*TokenAmountWithDecimals) UnmarshalText
