+# OG BLOCK — EconomyOS Showcase submission
+
+This folder is the submission package for the EconomyOS Community Showcase.
+It is a copy-ready mirror of what goes into a PR against
+[`Virtual-Protocol/acp-cli-demos`](https://github.com/Virtual-Protocol/acp-cli-demos).
+
+## What OG BLOCK is
+
+OG BLOCK turns real NFT holdings on Base into a public **culture score** and
+leaderboard — instead of ranking people by followers or engagement. A profile
+has two wallet slots:
+
+- **Human wallet** — the operator's personal holder wallet.
+- **Agent wallet** — an autonomous agent's wallet, verified as its own slot.
+
+NFTs held in **either** wallet accumulate into one combined score. Each slot is
+verified independently by signing a challenge **from that wallet's own key**, so
+an agent's on-chain identity is proven, not just claimed. Agent wallets are
+recognized on-chain through an **AgentIdentity** NFT
+(`0x8004a169fb4a3325136eb29fa0ceb6d2e539a432` on Base).
+
+**EconomyOS primitive used:** `wallet` (Agent Wallet). Designed to extend into
+the ACP flow next.
+
+## Live proof
+
+- App: https://www.joinog.xyz
+- Leaderboard (live scores): https://www.joinog.xyz/leaderboard
+- Example verified profile: https://www.joinog.xyz/u/airplanestar_
+- Public profile API (JSON): https://www.joinog.xyz/api/profile/airplanestar_
+- Source: https://github.com/airplanestar888/OG-Block
+- Demo video (agent wallet link flow): https://x.com/ogblockchain/status/2092282854105547104
+
+### Agent used in the demo
+
+- **Agent**: airplane (ACP agent, HYBRID role)
+- **Agent ID**: `019f0a02-50d4-7169-b047-a5771369e32a`
+- **Agent wallet**: `0x3282f5ae930f8be53695de152cf890b9385e8263` (Base mainnet)
+- **AgentIdentity NFT**: #58870 on `0x8004a169fb4a3325136eb29fa0ceb6d2e539a432`
+- **Linked profile**: [@airplanestar_](https://www.joinog.xyz/u/airplanestar_)
+
+Status: live on Base mainnet — 16 profiles onboarded, 2,000+ NFTs tracked,
+top score 61.5K and a combined ecosystem score of 99.2K.
+
+## Scoring model
+
+`100` for holding ≥1 NFT, `+25` per additional NFT, `+50` per NFT with a rare
+trait, `+75` per early token (id < 500). Combined across both wallet slots.

+# Demo Prompt
+
+Reproduce the OG BLOCK agent-link flow end-to-end with any ACP agent.
+
+## Operator side (one-time)
+
+On https://joinog.xyz/dashboard, open the **Agent Wallet** panel and tap
+**Connect agent**. The modal generates a one-time code (`OGB-XXXX-XXXX`,
+single-use, expires in 15 minutes) together with a copy-paste instruction.
+
+Equivalent authenticated API call:
+
+```http
+POST /api/agent/link-code
+→ { "code", "expiresAt", "ttlMs", "handle", "instruction" }
+```
+
+## Agent side (paste this to your agent)
+
+```text
+TASK: register YOUR wallet as the agent wallet of the OG BLOCK profile
+@<OPERATOR_HANDLE>. Follow only this instruction.
+
+1. Run: acp agent use --agent-id <YOUR_AGENT_ID>
+2. Run: acp wallet address   ← record this address, it is what you register
+3. Sign this exact text with that key (EIP-191 personal_sign), using the
+   CURRENT UTC time:
+   ---
+   OG BLOCK agent link
+   Code: <CODE>
+   Agent wallet: <YOUR_ADDRESS>
+   Timestamp: <ISO_8601_UTC_NOW>
+   ---
+   acp wallet sign-message --chain-id 8453 --message "<THE_EXACT_TEXT>"
+4. POST JSON to https://joinog.xyz/api/agent/link
+   {
+     "code": "<CODE>",
+     "address": "<YOUR_ADDRESS>",
+     "chainId": 8453,
+     "message": "<THE_EXACT_SIGNED_TEXT>",
+     "signature": "<0x_SIGNATURE>"
+   }
+5. Report the response body.
+
+Rules: the signature must recover to exactly <YOUR_ADDRESS> (plain ECDSA);
+if your wallet is a smart account driven by an internal operator key, submit
+THAT signer EOA address instead. Failed attempts do not consume the code.
+```
+
+Success looks like:
+
+```json
+{ "ok": true, "handle": "<operator_handle>", "agentWallet": "<your address>", "score": 1234 }
+```
+
+Then verify publicly:
+
+```bash
+curl https://joinog.xyz/api/profile/<operator_handle>
+```

+## Environment
+
+| Item | Value |
+| --- | --- |
+| Chain | Base mainnet (8453) |
+| Agent | airplane (ACP agent, HYBRID role) |
+| Agent ID | `019f0a02-50d4-7169-b047-a5771369e32a` |
+| Agent wallet (ACP) | `0x3282f5ae930f8be53695de152cf890b9385e8263` |
+| AgentIdentity NFT | #58870 on `0x8004a169fb4a3325136eb29fa0ceb6d2e539a432` |
+| Operator profile | `@airplanestar_` |
+| Endpoint under test | `POST https://joinog.xyz/api/agent/link` |
+
+## Run log
+
+### 1. One-time code issued
+
+```
+code=OGB-****-****  expiresAt=2026-08-25T15:52:51.593Z
+```
+
+Instruction block generated server-side by `POST /api/agent/link-code`
+(authenticated operator session required — unauthenticated calls correctly
+return `401 Unauthorized`, verified).
+
+### 2. Agent selects its ACP wallet and signs
+
+```bash
+acp agent use --agent-id <AGENT_ID>
+acp wallet address
+# → 0x3282f5ae930f8be53695de152cf890b9385e8263
+acp wallet sign-message --chain-id 8453 --message "<CHALLENGE_TEXT>"
+# → signature=0x7261c6874eda1cf5c2…e1d69d1c   (truncated, redacted)
+```
+
+### 3. POST /api/agent/link → HTTP 200
+
+```json
+{
+  "ok": true,
+  "handle": "airplanestar_",
+  "agentWallet": "0x3282f5ae930f8be53695de152cf890b9385e8263",
+  "score": 100
+}
+```
+
+### 4. Database state after linking
+
+```json
+{
+  "slots": [
+    {
+      "address": "0x3282f5ae930f8be53695de152cf890b9385e8263",
+      "wallet_slot": "agent",
+      "verified_at": "2026-08-25T15:25:30.806+00:00"
+    }
+  ],
+  "score": { "score": 100, "nft_count": 1, "rank": 16 }
+}
+```
+
+Public read-back matches:
+`https://joinog.xyz/api/profile/airplanestar_` → score 100, nftCount 1,
+agentWallet linked.
+
+## Negative cases observed in the field
+
+| Case | Server response | Note |
+| --- | --- | --- |
+| Unauthenticated code generation | `401 {"error":"Unauthorized"}` | Guard works as designed |
+| Signature recovers to a different address than submitted (smart-account operator key) | `400 {"error":"Signature could not be verified"}` | Documented fix: submit the signer EOA address instead |
+| Failed attempts do NOT consume the code | — | Retry within expiry succeeds after fixing the payload |
+
+## Post-run rescore
+
+Combined score recalculated automatically across human + agent slots after a
+successful link (verified-contract NFTs only). Registration retry-hardened:
+transient provider errors during rescoring are retried before surfacing.
