Types

type Record

type Record struct {
	Signature []byte // Cryptographic signature of record contents
	Sequence  uint64 // The sequence number. Nodes should increase the number whenever the record changes and republish the record.
	IDScheme  string // name of identity scheme, e.g. “v4”

	PrivateKey *secp256k1.PrivateKey
	PublicKey  *secp256k1.PublicKey

	Ip      net.IP
	TcpPort uint16
	UdpPort uint16

	Ip6      net.IP
	Tcp6Port uint16 // IPv6-specific TCP port. If omitted, same as TcpPort.
	Udp6Port uint16 // IPv6-specific UDP port. If omitted, same as UdpPort.

	SentPing     time.Time
	SentPingHash [32]byte
	ReceivedPong time.Time
	ReceivedPing time.Time
}

An Ethereum Node Record contains network information about a node on the dsicv5 p2p network. The specification is detailed in https://eips.ethereum.org/EIPS/eip-778.

func ParseV4

func ParseV4(s string) (*Record, error)

func UnmarshalText

func UnmarshalText(str string) (Record, error)

Given a text encoding of an Ethereum Node Record, which is formatted as the base-64 encoding of its RLP content prefixed by enr:, this method decodes it into an Record struct.
