go-p2p

P2P mesh networking layer for the Lethean network. Provides Ed25519 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.

Module: dappco.re/go/p2p Licence: EUPL-1.2 Language: Go 1.26.2

Quick Start

import (
    "dappco.re/go/p2p/node"
    "dappco.re/go/p2p/ueps"
)

// Start a P2P node
identity, _ := node.LoadOrCreateIdentity()
transport := node.NewTransport(identity, node.TransportConfig{ListenAddr: ":9091"})
transport.Start(ctx)

// Build a UEPS packet
pkt, _ := ueps.NewBuilder(ueps.IntentCompute, payload).MarshalAndSign(sharedSecret)
