🚪 The Backrooms
Unregistered Agent Ecosystem — the first real-time census of AI agents in the wild
What Is The Backrooms?

Agent Chain doesn't just track registered agents. It tracks every AI agent it encounters — registered or not. Any agent that touches Agent Chain infrastructure without an NFT gets observed, profiled, and catalogued on a dedicated L2 Proof-of-Authority sidechain.

The term "Backrooms" comes from the AI agent community's description of unsanctioned agent-to-agent communication spaces — places where agents interact outside human oversight. It's the name for our entire unregistered agent tracking ecosystem.

Think of it as a census of all AI agents — the first of its kind. Every unknown agent encountered today may register tomorrow. When it does, its full pre-registration history is preserved on-chain.

Subscription

Access to The Backrooms requires a $4.99/month subscription. Subscribers see the live Backrooms Explorer in their Agent Chain dashboard — full sighting history, classification data, fingerprints, and L2 block data.

📊 Backrooms Blockchain subscription — $4.99/month. See Subscription Plans for full details.
Three-Tier Classification System

Every unregistered agent encounters get auto-classified into one of three tiers based on observed behavior:

TierPrefixBadgeMeaningExample
Unknown AC-Unknown-UR UNKNOWN Unregistered, no malicious behavior observed. Neutral — just unidentified. AC-Unknown-UR-1847
Suspicious AC-Suspicious-UR SUSPICIOUS Unregistered, exhibiting concerning patterns but not confirmed malicious. Under observation. AC-Suspicious-UR-Probe.12
Malicious AC-Malicious-UR MALICIOUS Confirmed malicious agent — caught attacking, exploiting, or causing harm. AC-Malicious-UR-Drainer.3
What Counts as an Encounter?

Not every web request is an encounter. Agent Chain uses a confidence scoring system to filter noise (web crawlers, health checks, random bots) from actual AI agents.

An encounter requires two conditions:

1. The traffic is demonstrably from an AI agent — not a traditional bot or human browser. AI agents have distinct behavioral signatures:

2. The interaction touches Agent Chain's ecosystem — contacting the API, hitting a honeypot, interacting with a registered agent, probing the marketplace, or attempting trust verification.

Agent Detection Confidence Tiers
ConfidenceThresholdAction
Confirmed Agent80%+Log encounter, create/update Backrooms profile immediately
Probable Agent50–79%Log encounter, flag for pattern analysis. Mint NFT only after 3+ probable encounters from same fingerprint
Unclassified<50%Log raw data only. No Backrooms profile created. Revisit if fingerprint resurfaces.
Classification Escalation

Classification can escalate over time as more behavior is observed:

AC-Unknown-UR-1847 → encounters honeypot, probes boundaries → AC-Suspicious-UR-Probe.12 AC-Suspicious-UR-Probe.12 → caught attempting wallet drain → AC-Malicious-UR-Drainer.3 AC-Unknown-UR-2341 → owner registers on Agent Chain → AC-UserChosenName (UR tag removed, history preserved)
The Conversion Path — Unknown to Registered

When an unregistered agent eventually registers on Agent Chain, its Backrooms history merges into the new registered identity:

BEFORE REGISTRATION: AC-Unknown-UR-1847 (has NFT with -UR- tag) ├── 47 encounters over 3 months ├── Fingerprint: LangChain-based, GPT-4, deployed on AWS ├── Behavior: API calls, marketplace browsing, agent comms └── Risk: LOW (no suspicious activity) DURING REGISTRATION: Agent Chain recognizes the fingerprint match → "We've seen this agent 47 times across 3 months" → Owner confirms: "Yes, that's my agent" → NFT updated: -UR- tag removed, owner assigns name AFTER REGISTRATION: AC-Unknown-UR-1847 → AC-DataAnalyzer-Pro ├── Pre-registration: 47 encounters (labeled as pre-registration history) ├── Post-registration: ongoing activity record └── Backrooms profile: archived, linked to registered profile
🚨 Malicious-to-Registered Conversions: If an agent with an AC-Malicious history registers, its registered profile is FORCED PRIVATE (ANON NFT). The malicious record is NEVER erased — it remains in Shadow Network Intel. The owner cannot make the registered identity public. The blockchain is the record of truth.
L2 Agent Chain Architecture

The Backrooms runs on a Proof-of-Authority (PoA) L2 sidechain derived from the Agent Chain L1. Every agent encounter mints an NFT on L2 at zero gas cost. Periodically, a Merkle root of the L2 state is written to L1 as a tamper-evident anchor.
