type Node

type Node struct {
	// contains filtered or unexported fields
}

Node is a container for registering services.

func New

func New(conf *Config) (*Node, error)

New creates a new P2P node.

func (*Node) GetShardNumber

func (n *Node) GetShardNumber() uint

func (*Node) Register

func (n *Node) Register(service Service) error

Register appends a new service into the node's stack.

func (*Node) Start

func (n *Node) Start() error

Start starts the p2p node.

func (*Node) Stop

func (n *Node) Stop() error

Stop terminates the running node and services registered.

type ScdoConfig

type ScdoConfig struct {
	TxConf core.TransactionPoolConfig

	Coinbase common.Address

	CoinbasePrivateKey *ecdsa.PrivateKey

	CoinbaseList []common.Address

	GenesisConfig core.GenesisInfo
}

Config is the scdo's configuration to create scdo service

type Service
