var ErrMissingPrivateInfo = fmt.Errorf("can not access private information for a public node type")

ErrMissingPrivateInfo is returned when a method is called on NodeInfo that is only valid on instances containing private info.

Functions

func ToIdentityList 

func ToIdentityList(nodes []NodeInfo) flow.IdentityList

Types

type NodeConfig 

type NodeConfig struct {
	// Role is the flow role of the node (ex Collection, Consensus, ...)
	Role flow.Role

	// Address is the networking address of the node (IP:PORT), not to be
	// confused with the address of the flow account associated with the node's
	// machine account.
	Address string

	// Stake is the stake of the node
	Stake uint64
}

NodeConfig contains configuration information used as input to the bootstrap process.

type NodeInfo 

type NodeInfo struct {

	// NodeID is the unique identifier of the node in the network
	NodeID flow.Identifier

	// Role is the flow role of the node (collection, consensus, etc...)
	Role flow.Role

	// Address is the networking address of the node (IP:PORT), not to be
	// confused with the address of the flow account associated with the node's
	// machine account.
	Address string

	// Stake is the stake of the node
	Stake uint64
	// contains filtered or unexported fields
}

NodeInfo contains information for a node. This is used during the bootstrapping process to represent each node. When writing node information to disk, use `Public` or `Private` to obtain the appropriate canonical structure.

A NodeInfo instance can contain EITHER public keys OR private keys, not both. This can be ensured by using only using the provided constructors and NOT manually constructing an instance.

func FilterByRole 

func FilterByRole(nodes []NodeInfo, role flow.Role) []NodeInfo

func NewPrivateNodeInfo 

func NewPrivateNodeInfo(
	nodeID flow.Identifier,
	role flow.Role,
	addr string,
	stake uint64,
	networkKey crypto.PrivateKey,
	stakingKey crypto.PrivateKey,
) NodeInfo

func NewPublicNodeInfo 

func NewPublicNodeInfo(
	nodeID flow.Identifier,
	role flow.Role,
	addr string,
	stake uint64,
	networkKey crypto.PublicKey,
	stakingKey crypto.PublicKey,
) NodeInfo

func NodeInfoFromIdentity added in v0.16.1 

func NodeInfoFromIdentity(identity *flow.Identity) NodeInfo

NodeInfoFromIdentity converts an identity to a public NodeInfo

func PrivateNodeInfoFromIdentity added in v0.20.0 

func PrivateNodeInfoFromIdentity(identity *flow.Identity, networkKey, stakingKey crypto.PrivateKey) NodeInfo

func Sort added in v0.17.0 

func Sort(nodes []NodeInfo, order flow.IdentityOrder) []NodeInfo

Sort sorts the NodeInfo list using the given ordering.

func (NodeInfo) Identity 

func (node NodeInfo) Identity() *flow.Identity

Identity returns the node info as a public Flow identity.

func (NodeInfo) NetworkPubKey 

func (node NodeInfo) NetworkPubKey() crypto.PublicKey

func (NodeInfo) PartnerPublic 

func (node NodeInfo) PartnerPublic() PartnerNodeInfoPub

PartnerPublic returns the public data for a partner node.

func (NodeInfo) Private 

func (node NodeInfo) Private() (NodeInfoPriv, error)

Private returns the canonical private encodable structure.

func (NodeInfo) PrivateKeys 

func (node NodeInfo) PrivateKeys() (*NodePrivateKeys, error)

func (NodeInfo) Public 

func (node NodeInfo) Public() NodeInfoPub

Public returns the canonical public encodable structure

func (NodeInfo) StakingPubKey 

func (node NodeInfo) StakingPubKey() crypto.PublicKey

func (NodeInfo) Type 

func (node NodeInfo) Type() NodeInfoType

Type returns the type of the node info instance.

type NodeInfoPriv 

type NodeInfoPriv struct {
	Role           flow.Role
	Address        string
	NodeID         flow.Identifier
	NetworkPrivKey encodable.NetworkPrivKey
	StakingPrivKey encodable.StakingPrivKey
}

Defines the canonical structure for encoding private node info.

type NodeInfoPub 

type NodeInfoPub struct {
	Role          flow.Role
	Address       string
	NodeID        flow.Identifier
	Stake         uint64
	NetworkPubKey encodable.NetworkPubKey
	StakingPubKey encodable.StakingPubKey
}

Defines the canonical structure for encoding public node info.

func ToPublicNodeInfoList 

func ToPublicNodeInfoList(nodes []NodeInfo) []NodeInfoPub

type NodeInfoType 

type NodeInfoType int

NodeInfoType enumerates the two different options for 

const (
	NodeInfoTypeInvalid NodeInfoType = iota
	NodeInfoTypePublic
	NodeInfoTypePrivate
)

type NodeMachineAccountInfo added in v0.20.0 

type NodeMachineAccountInfo struct {
	// Address is the flow address of the machine account, not to be confused
	// with the network address of the node.
	Address string

	// EncodedPrivateKey is the private key of the machine account
	EncodedPrivateKey []byte

	// KeyIndex is the index of the key in the associated machine account
	KeyIndex uint

	// SigningAlgorithm is the algorithm used by the machine account along with
	// the above private key to create cryptographic signatures
	SigningAlgorithm sdkcrypto.SignatureAlgorithm

	// HashAlgorithm is the algorithm used for hashing
	HashAlgorithm sdkcrypto.HashAlgorithm
}

NodeMachineAccountInfo defines the structure for a bootstrapping file containing private information about the node's machine account. The machine account is used by the protocol software to interact with Flow as a client autonomously as needed, in particular to run the DKG and generate root cluster quorum certificates when preparing for an epoch.

func (NodeMachineAccountInfo) FlowAddress added in v0.22.0 

func (info NodeMachineAccountInfo) FlowAddress() flow.Address

func (NodeMachineAccountInfo) MustPrivateKey added in v0.22.0 

func (info NodeMachineAccountInfo) MustPrivateKey() crypto.PrivateKey

func (NodeMachineAccountInfo) PrivateKey added in v0.22.0 

func (info NodeMachineAccountInfo) PrivateKey() (crypto.PrivateKey, error)

func (NodeMachineAccountInfo) SDKAddress added in v0.22.0 

func (info NodeMachineAccountInfo) SDKAddress() sdk.Address

type NodeMachineAccountKey added in v0.20.0 

type NodeMachineAccountKey struct {
	PrivateKey encodable.MachineAccountPrivKey
}

NodeMachineAccountKey contains the private configration need to construct a NodeMachineAccountInfo object. This is used as an intemediary by the bootstrap scripts for storing the private key before generating a NodeMachineAccountInfo.

type NodePrivateKeys 

type NodePrivateKeys struct {
	StakingKey crypto.PrivateKey
	NetworkKey crypto.PrivateKey
}

NodePrivateKeys is a wrapper for the private keys for a node, comprising all sensitive information for a node.

type PartnerNodeInfoPub 

type PartnerNodeInfoPub struct {
	Role          flow.Role
	Address       string
	NodeID        flow.Identifier
	NetworkPubKey encodable.NetworkPubKey
	StakingPubKey encodable.StakingPubKey
}

PartnerNodeInfoPub represents public information about a partner/external node. It is identical to NodeInfoPub, but without stake information, as this is determined externally to the process that generates this information.
