Hi, prvKey, _, err := crypto.GenerateKeyPairWithReader(crypto.RSA, 2048, rand.Reader)
if err != nil {
log.Println(err)
return
}
relay1, err := libp2p.New(libp2p.Identity(prvKey), libp2p.ListenAddrStrings("/ip4/0.0.0.0/tcp/9876", "/ip4/0.0.0.0/udp/9876/quic-v1"))
if err != nil {
log.Printf("Failed to create relay1: %v", err)
return
}
_, err = relay.New(relay1)
if err != nil {
log.Printf("Failed to instantiate the relay: %v", err)

@iGwkang thanks buddy, I am trying to build a blockchain, therefore each node should be behaving same, when someone wants to join the p2p network, I want each of the nodes to act as a bootstrap node, is this possible with this example and your solution after initial start of the network, and some number of peers are active? |
hi, im trying to build a toy blockchain to learn fundamentals. I want to use libp2p for communicating nodes. (I tried couple of things, correct me if I tell anything wrong below)
I tried
pub/sub
example, but that was communicating over a relay node, peers doesn't directly communicating each other but messages coming from a single bootstrapper node.Then I tried
chat with mdns
example, I could do the things I want to do using it, but then I realized I cannot use that globally, its only for LAN network.Then I switched to
chat with rendezvous
example, it seems like it can solve my problem, but I cannot run the nodes, im getting the following error, immediately after starting the first node.My question is, for my case, which examples should I rely on for communicating the nodes in my blockchain? And if its the
chat with rendezvous
example, how I can fix the error below :Dthanks in advance
