go-p2p

P2P mesh networking layer for the Lethean network. Provides X25519 node identity, an encrypted WebSocket transport with HMAC-SHA256 challenge-response handshake, KD-tree peer selection across four dimensions (latency, hops, geography, reliability score), UEPS wire protocol (RFC-021) TLV packet builder and reader, UEPS intent routing with a threat circuit breaker, and TIM deployment bundle encryption with Zip Slip and decompression-bomb defences.

Quick Start

import (
    "log"

    "dappco.re/go/core/p2p/node"
    "dappco.re/go/core/p2p/ueps"
)

nm, err := node.NewNodeManager()
if err != nil {
    log.Fatal(err)
}
if !nm.HasIdentity() {
    if err := nm.GenerateIdentity("worker-1", node.RoleWorker); err != nil {
        log.Fatal(err)
    }
}

registry, err := node.NewPeerRegistry()
if err != nil {
    log.Fatal(err)
}

transport := node.NewTransport(nm, registry, node.DefaultTransportConfig())
if err := transport.Start(); err != nil {
    log.Fatal(err)
}

payload := []byte(`{"job":"hashrate"}`)
sharedSecret := make([]byte, 32)
pkt, err := ueps.NewBuilder(node.IntentCompute, payload).MarshalAndSign(sharedSecret)
if err != nil {
    log.Fatal(err)
}
_ = pkt
