@dgb-wallet/p2p

DigiByte P2P client for the Maximum Privacy backend. Client-side chain data via BIP157/158 compact block filters — the wallet does its own address matching locally, so peers never learn which addresses it cares about.

Current status: Milestone 1 (peer connect + version handshake).

Planned milestones:

  1. ✅ Peer connect + version handshake
  2. Peer discovery via DNS seeds + getaddr
  3. Header sync (getheaders / headers)
  4. BIP157 filter negotiation + BIP158 filter download
  5. Filter probing (address → scripthash → filter match)
  6. Block fetching for filter hits
  7. Transaction broadcast (inv / tx)
  8. Dandelion++ integration
  9. Persistent cache

Milestone 1 demo

cd "D:\Dev\SilentCode\Digibyte"
npm install                        # first time only
npm run build -w @dgb-wallet/core
npm run handshake -w @dgb-wallet/p2p

Resolves DGB DNS seeds → connects to real live peers on port 12024 → performs the version/verack handshake → reports each peer's protocol version, user agent, service flags, and chain tip height.

To target a specific peer IP:

npm run handshake -w @dgb-wallet/p2p -- 1.2.3.4

src/
  hash.ts     — double-SHA256 for message checksums
  varint.ts   — Bitcoin/DGB compact-size int encoding
  framing.ts  — 24-byte header + payload + checksum, multi-frame parsing
  version.ts  — version/verack message encode/decode, service flag bits
  peer.ts     — per-peer TCP + handshake state machine
  index.ts    — re-exports

  handshake-demo.ts — Milestone 1 end-to-end demo

Depends on @dgb-wallet/core for network parameters (DGB_P2P.magic, defaultPort, dnsSeeds).
