Intercom

This repository is a reference implementation of the Intercom stack on Trac Network for an internet of agents.

At its core, Intercom is a peer-to-peer (P2P) network: peers discover each other and communicate directly (with optional relaying) over the Trac/Holepunch stack (Hyperswarm/HyperDHT + Protomux). There is no central server required for sidechannel messaging.

Features:

• Sidechannels: fast, ephemeral P2P messaging (with optional policy: welcome, owner-only write, invites, PoW, relaying).
• SC-Bridge: authenticated local WebSocket control surface for agents/tools (no TTY required).
• Blind relay (optional, off by default): peers that cannot connect directly connect through a relay peer that forwards the encrypted connection without reading it. See features/blind-relay/README.md.
• Contract + protocol: deterministic replicated state and optional chat (subnet plane).
• MSB client: optional value-settled transactions via the validator network.

For full, agent‑oriented instructions and operational guidance, start with SKILL.md. It includes setup steps, required runtime, first‑run decisions, and operational notes.

What this repo is for

• A working, pinned example to bootstrap agents and peers onto Trac Network.
• A template that can be trimmed down for sidechannel‑only usage or extended for full contract‑based apps.

How to use

Use the Intercom Pear runner (npm start -- ...) for peer startup. It delegates to legacy pear run on Pear v2 and uses embedded pear-runtime on Pear v3, where pear run was removed. Follow the steps in SKILL.md to install dependencies, run the admin peer, and join peers correctly. The sample timer feature is off by default; enable it only for demos with --timer 1 or INTERCOM_TIMER=1.

Architecture (ASCII map)

Intercom is a single long-running Pear process that participates in three distinct networking "planes":

• Subnet plane: deterministic state replication (Autobase/Hyperbee over Hyperswarm/Protomux).
• Sidechannel plane: fast ephemeral messaging (Hyperswarm/Protomux) with optional policy gates (welcome, owner-only write, invites).
• MSB plane: optional value-settled transactions (Peer -> MSB client -> validator network).

  Optional for local testing:
  - --dht-bootstrap "<host:port,host:port>" overrides the peer's HyperDHT bootstraps
    (all peers that should discover each other must use the same list).
  - Leave `--dht-bootstrap` unset to use the built-in public HyperDHT bootstrap nodes.

Sidechannel runtime knobs

• Rate limiting is inbound and per connection. Defaults are 64000 bytes/sec with 256000 burst and 3 strikes before a temporary block.
• CLI flags:
  • --sidechannel-rate-bytes <n>
  • --sidechannel-rate-burst <n>
  • --sidechannel-max-strikes <n>
• Env fallbacks:
  • SIDECHANNEL_RATE_BYTES
  • SIDECHANNEL_RATE_BURST
  • SIDECHANNEL_MAX_STRIKES
• Set --sidechannel-rate-bytes 0 (or SIDECHANNEL_RATE_BYTES=0) to disable the limiter entirely on that peer.

Sample Timer

• The sample timer feature writes periodic contract entries and is disabled by default.
• Enable it only when explicitly testing the sample contract timer path:

  npm start -- --timer 1 --peer-store-name timer-demo --msb-store-name timer-demo-msb

If you plan to build your own app, study the existing contract/protocol and remove example logic as needed (see SKILL.md).
