 The go p2p library implementation of the CESS distributed storage network, which is customized based on [go-libp2p](https://github.com/libp2p/go-libp2p), has many advantages, and at the same time abandons the bandwidth and space redundancy caused by multiple file backups, making nodes more focused on storage allocation Give yourself data to make it more in line with the needs of the CESS network.

-The following is an example of creating an p2p host:
+The following code demonstrates how to create a p2p node and perform node discovery:
 ```
-p2phost, err := p2pgo.New(
-    privatekeyPath,
-    p2pgo.ListenAddrStrings(addr, port), // regular tcp connections
-    p2pgo.Workspace(workspace),
+package main
+
+import (
+	"context"
+	"fmt"
+	"log"
+	"os"
+	"strconv"
+	"time"
+
+	p2pgo "github.com/CESSProject/p2p-go"
+	"github.com/CESSProject/p2p-go/core"
+	"golang.org/x/time/rate"
 )
+
+func main() {
+	var ok bool
+	var node = &core.Node{}
+	ctx := context.Background()
+	port, err := strconv.Atoi(os.Args[1])
+	if err != nil {
+		fmt.Println("please enter os.Args[1] as port")
+		os.Exit(1)
+	}
+
+	h1, err := p2pgo.New(
+		ctx,
+		p2pgo.PrivatekeyFile(".private1"),
+		p2pgo.ListenPort(port),
+		p2pgo.Workspace("."),
+		p2pgo.BootPeers([]string{
+			"_dnsaddr.boot-kldr-testnet.cess.cloud",
+		}),
+		p2pgo.ProtocolPrefix("/kldr-testnet"),
+	)
+	if err != nil {
+		panic(err)
+	}
+	defer h1.Close()
+
+	node, ok = h1.(*core.Node)
+	if !ok {
+		panic(err)
+	}
+
+	fmt.Println(node.Addrs(), node.ID())
+
+	node.RouteTableFindPeers(0)
+
+	tick := time.NewTicker(time.Second * 30)
+	defer tick.Stop()
+
+	var r = rate.Every(time.Second * 3)
+	var limit = rate.NewLimiter(r, 1)
+
+	for {
+		select {
+		case peer, ok := <-node.GetDiscoveredPeers():
+			if !ok {
+				break
+			}
+			if limit.Allow() {
+				tick.Reset(time.Second * 30)
+			}
+			if len(peer.Responses) == 0 {
+				break
+			}
+			for _, v := range peer.Responses {
+				log.Println("found: ", v.ID.Pretty(), v.Addrs)
+			}

+			node.RouteTableFindPeers(0)
