Functions

func SyncEth1Events

func SyncEth1Events(logger *zap.Logger, client Client, storage SyncOffsetStorage, observerID string, syncOffset *SyncOffset) error

SyncEth1Events sync past events

Types

type Client

type Client interface {
	EventsSubject() pubsub.Subscriber
	Start() error
	Sync(fromBlock *big.Int) error
}

Client represents the required interface for eth1 client

type Event

type Event struct {
	Log  types.Log
	Data interface{}
}

Event represents an eth1 event log in the system

type Oess

type Oess struct {
	Index             *big.Int
	OperatorPublicKey []byte
	SharedPublicKey   []byte
	EncryptedKey      []byte
}

Oess struct stands for operator encrypted secret share

type OperatorAddedEvent

type OperatorAddedEvent struct {
	Name           string
	PublicKey      []byte
	PaymentAddress common.Address
	OwnerAddress   common.Address
}

OperatorAddedEvent struct represents event received by the smart contract

func ParseOperatorAddedEvent

func ParseOperatorAddedEvent(logger *zap.Logger, data []byte, contractAbi abi.ABI) (*OperatorAddedEvent, bool, error)

ParseOperatorAddedEvent parses an OperatorAddedEvent

type OperatorPrivateKeyProvider

type OperatorPrivateKeyProvider = func() (*rsa.PrivateKey, error)

OperatorPrivateKeyProvider is a function that returns the operator private key

type SyncEndedEvent

type SyncEndedEvent struct {
	// Success returns true if the sync went well (all events were parsed)
	Success bool
	// Logs is the actual logs that we got from eth1
	Logs []types.Log
}

SyncEndedEvent meant to notify an observer that the sync is over

type SyncOffset

type SyncOffset = big.Int

SyncOffset is the type of variable used for passing around the offset

func DefaultSyncOffset

func DefaultSyncOffset() *SyncOffset

DefaultSyncOffset returns the default value (block number of the first event from the contract)

func HexStringToSyncOffset

func HexStringToSyncOffset(shex string) *SyncOffset

HexStringToSyncOffset converts an hex string to SyncOffset

type SyncOffsetStorage

type SyncOffsetStorage interface {
	// SaveSyncOffset saves the offset (block number)
	SaveSyncOffset(offset *SyncOffset) error
	// GetSyncOffset returns the sync offset
	GetSyncOffset() (*SyncOffset, error)
}

SyncOffsetStorage represents the interface for compatible storage

type ValidatorAddedEvent

type ValidatorAddedEvent struct {
	PublicKey    []byte
	OwnerAddress common.Address
	OessList     []Oess
}

ValidatorAddedEvent struct represents event received by the smart contract

func ParseValidatorAddedEvent

func ParseValidatorAddedEvent(logger *zap.Logger, operatorPrivateKey *rsa.PrivateKey, data []byte, contractAbi abi.ABI) (*ValidatorAddedEvent, bool, error)

ParseValidatorAddedEvent parses ValidatorAddedEvent
