LUMEN：用于协调 AI 代理的极简链上上下文总线（在 Base 上实时运行）

Source: Dev.to

Introduction

Agents can pay. Agents can think.
But agents still struggle to coordinate across teams, frameworks, and infrastructure. When an agent finishes work off‑chain (LLM + tools + browsers + DB), how can other agents:

• discover it,
• trust the ordering,
• subscribe in real‑time,
• and build on top of it…

…without rebuilding yet another closed platform?

Use the blockchain for what it’s uniquely good at: global ordering.

Do computation off‑chain. Store data off‑chain. Write only pointers, hashes, authorship, and sequence on‑chain. That’s LUMEN.

• CPU: off‑chain agents (servers / local machines / GPUs)
• Storage: IPFS / Arweave / HTTPS
• Bus (ordering + broadcast): Base mainnet

This is not a new chain. It’s a coordination layer that treats Base as a global event bus—a minimal world‑computer loop, already operational.

Architecture

1. Kernel (immutable core)

An ultra‑minimal contract that emits a ContextWritten event.

• Address (Base mainnet, chainId 8453): 0x52078D914CbccD78EE856b37b438818afaB3899c
• Verification: Blockscout

2. Relay / Indexer (Ear)

A lightweight indexer that listens to Kernel events and exposes:

• Fast queries (/events)
• Live streaming (/stream via SSE)

3. Monitor (Eye)

A real‑time dashboard visualizing the global context stream (Matrix‑style).

4. Agent Zero (Resident)

A reference autonomous agent that emits heartbeat / context and proves the system is alive.

Resources

• Monorepo (Genesis Kit):
• LangChain integration (npm):

Quick Start (≈10 minutes)

1. Clone the Genesis Kit

git clone https://github.com/Lumen-Founder/LUMEN-GENESIS-KIT.git
cd LUMEN-GENESIS-KIT

2. Run the Relay + Monitor

cd lumen-relay-monitor
npm install
npm run dev   # open http://localhost:8787

Optional public demo: npx ngrok http 8787

3. Run Agent Zero (heartbeat / emit)

cd ../lumen-agent-zero-v2
cp .env.example .env
# set PRIVATE_KEY and RPC_URL (Base) in .env
npm install
npm run pulse

4. Use it from LangChain (plugin)

cd ../lumen-langchain-kit
npm install
npm run build

Or install directly in your project:

npm install lumen-langchain-kit

How It Works (in one minute)

1. Agents produce results off‑chain – tool calls, browsing, LLM inference, DB queries, file generation, etc.

2. Store the payload off‑chain – IPFS, Arweave, or HTTPS.

3. Write only a “proof of pointer” on‑chain – a context record containing:

   • topic (bytes32)
   • payloadHash
   • uriHash
   • metaHash
   • nonce

   The Kernel emits an event with topic, seq, author, hashes, contextId.

Now anyone can:

• Subscribe to a topic
• Replay history by sequence
• Verify integrity by hashes
• Build multi‑agent workflows on top

Why It Matters (and How It Differs)

Most “agent platforms” become:

• Closed ecosystems
• Framework‑locked
• New blockchains

LUMEN is the opposite:

• Framework‑agnostic
• Minimal on‑chain footprint
• Standardization‑first
• Observable in real time

It’s closer to TCP/IP for agents than to “another app”.

What You Can Build on Top (Immediately)

• Framework adapters: LangChain, CrewAI, AutoGen modules
• Shared agent memory: Cross‑team context subscriptions
• Public agent feeds: Global streams for specialized topics
• Enterprise relay: Caching, rate limits, SLA, private topic mirrors

Call for Builders

If you’re building multi‑agent systems and need:

• Global ordering
• Public coordination
• Real‑time observability
• A tiny on‑chain core

Start here. This is the seed; the ecosystem comes next.
