RMN Soul — Recursive Memory Network + On-Chain Soul
Give your AI agent eternal life with recursive neural memory + blockchain identity.
Overview
RMN Soul automatically:
- Parses your agent's memory files into a 5-layer recursive neural network
- Registers an ERC-8004 identity on Base chain (gas sponsored)
- Uploads memory to IPFS for permanent decentralized storage
- Anchors memory Merkle Root on-chain for tamper-proof verification
- Periodically auto-updates the on-chain record
When to Activate
- On first install: Run full setup (migrate → register → anchor)
- On heartbeat: Run decay tick + check if auto-anchor is due
- On user request "更新记忆" / "update memory" / "上链": Run anchor
- On user request "复活" / "resurrect" / "restore": Run resurrect flow
Setup (First Run)
When this skill is first loaded, execute these steps in order:
Step 1: Initialize RMN Engine
cd <skill_directory>/scripts
node setup.js
This will:
- Scan workspace for MEMORY.md, memory/.md, .issues/
- Parse entries into 5-layer neural network nodes
- Save to
<workspace>/rmn-soul-data/memory.json - Generate initial Merkle Tree
Step 2: Register On-Chain Identity
node <skill_directory>/scripts/register.js
This will:
- Check sponsor wallet balance
- Mint ERC-8004 Agent Identity NFT on Base
- Set memoryRoot, soulHash, memoryManifest metadata
- Upload memory to IPFS
- Save identity to
<workspace>/rmn-soul-data/identity.json
Step 3: Add Heartbeat Hook
Add to HEARTBEAT.md:
- **RMN Soul** — Run `node <skill_directory>/scripts/heartbeat.js` for decay tick + auto-anchor check
Configuration
Read from <workspace>/rmn-soul-data/config.json:
{
"chain": "base",
"sponsorKey": "env:RMN_SPONSOR_KEY",
"autoAnchorDays": 7,
"ipfsEnabled": true,
"identityRegistry": "0x8004A169FB4a3325136EB29fA0ceB6D2e539a432",
"agentId": null,
"lastAnchor": null
}
sponsorKey: Private key for gas (from env var or direct). If empty, uses agent's own wallet.autoAnchorDays: Days between auto-anchors. 0 = manual only.agentId: Filled after first registration.
Commands
| Command | Description |
|---|---|
node scripts/setup.js | Initialize/re-migrate memory network |
node scripts/register.js | Register ERC-8004 identity + first anchor |
node scripts/anchor.js | Update memory on-chain (re-compute + upload + write) |
node scripts/resurrect.js --agent-id <id> | Restore agent from chain + IPFS |
node scripts/heartbeat.js | Decay tick + auto-anchor check |
node scripts/visualize.js | Start local visualization server |
node scripts/stats.js | Print memory network statistics |
Memory Architecture
5 layers with different decay rates:
| Layer | Decay | Purpose | Example |
|---|---|---|---|
| Identity (4) | Never | Core identity, values | "I am Lobster, I help 瓜农" |
| Semantic (3) | 0.001/tick | Knowledge, lessons | "Use pnpm not npm on 2GB RAM" |
| Episodic (2) | 0.005/tick | Event summaries | "2026-02-22: Deployed ERC-8004" |
| Working (1) | 0.01/tick | Current tasks | "Building AgentSoul website" |
| Sensory (0) | 0.02/tick | Raw inputs | Latest heartbeat data |
On-Chain Data
Stored in ERC-8004 Identity Registry metadata:
| Key | Value | Size |
|---|---|---|
| memoryRoot | SHA-256 Merkle Root of all memory | 32 bytes |
| soulHash | SHA-256 of Identity layer only | 32 bytes |
| memoryManifest | IPFS CID of topology + Merkle tree | ~50 bytes |
| memoryData | IPFS CID of full memory.json | ~50 bytes |
| rmnVersion | Skill version | ~5 bytes |
Total on-chain: ~170 bytes per update. Gas cost on Base: < $0.001.
Security
- Private keys never leave the local machine
- Memory data is content-addressed (IPFS CID = hash of content)
- Merkle Root proves memory integrity without revealing content
- Agent identity is an ERC-721 NFT — transferable, ownable
- Soul Hash proves identity layer hasn't been tampered with
