Functions ¶
func BootstrapIdentities ¶
func BootstrapIdentities(addresses []string, keys []string) (flow.IdentityList, error)
BootstrapIdentities converts the bootstrap node addresses and keys to a Flow Identity list where each Flow Identity is initialized with the passed address, the networking key and the Node ID set to ZeroID, role set to Access, 0 stake and no staking key.
Types ¶
type ObserverServiceBuilder ¶
type ObserverServiceBuilder struct {
*cmd.FlowNodeBuilder
*ObserverServiceConfig
// components
LibP2PNode p2p.LibP2PNode
FollowerState stateprotocol.MutableState
SyncCore *chainsync.Core
RpcEng *rpc.Engine
FinalizationDistributor *pubsub.FinalizationDistributor
FinalizedHeader *synceng.FinalizedHeaderCache
Committee hotstuff.DynamicCommittee
Finalized *flow.Header
Pending []*flow.Header
FollowerCore module.HotStuffFollower
Validator hotstuff.Validator
ExecutionDataDownloader execution_data.Downloader
ExecutionDataRequester state_synchronization.ExecutionDataRequester // for the observer, the sync engine participants provider is the libp2p peer store which is not
// available until after the network has started. Hence, a factory function that needs to be called just before
// creating the sync engine
SyncEngineParticipantsProviderFactory func() module.IdentifierProvider
// engines
FollowerEng *followereng.Engine
SyncEng *synceng.Engine
// contains filtered or unexported fields
}
ObserverServiceBuilder provides the common functionality needed to bootstrap a Flow observer service It is composed of the FlowNodeBuilder, the ObserverServiceConfig and contains all the components and modules needed for the observers
func NewFlowObserverServiceBuilder ¶
func NewFlowObserverServiceBuilder(opts ...Option) *ObserverServiceBuilder
func (*ObserverServiceBuilder) Build ¶
func (builder *ObserverServiceBuilder) Build() (cmd.Node, error)
Build enqueues the sync engine and the follower engine for the observer. Currently, the observer only runs the follower engine.
func (*ObserverServiceBuilder) BuildConsensusFollower ¶
func (builder *ObserverServiceBuilder) BuildConsensusFollower() cmd.NodeBuilder
func (*ObserverServiceBuilder) BuildExecutionDataRequester ¶
func (builder *ObserverServiceBuilder) BuildExecutionDataRequester() *ObserverServiceBuilder
func (*ObserverServiceBuilder) InitIDProviders ¶
func (builder *ObserverServiceBuilder) InitIDProviders()
func (*ObserverServiceBuilder) Initialize ¶
func (builder *ObserverServiceBuilder) Initialize() error
func (*ObserverServiceBuilder) ParseFlags ¶
func (builder *ObserverServiceBuilder) ParseFlags() error
type ObserverServiceConfig ¶
type ObserverServiceConfig struct {
// contains filtered or unexported fields
}
ObserverServiceConfig defines all the user defined parameters required to bootstrap an access node For a node running as a standalone process, the config fields will be populated from the command line params, while for a node running as a library, the config fields are expected to be initialized by the caller.
func DefaultObserverServiceConfig ¶
func DefaultObserverServiceConfig() *ObserverServiceConfig
DefaultObserverServiceConfig defines all the default values for the ObserverServiceConfig
type Option ¶
type Option func(*ObserverServiceConfig)
