Create Data Coin and Agent with Lighthouse I Nandit Mehra

Sun, Nov 2, 2025, 12:00 AM

Nandit (with Akash) introduces Lighthouse—a developer platform for permanent, verifiable, and access-controlled storage—and their new product 1mb.io, which lets you launch “data coins” and data agents to reward users (or A.I. agents) for contributing valuable datasets. Lighthouse tackles three pain points: long-term data is expensive/hard to verify, access control on decentralized storage is weak, and the tooling is fragmented. Their solution combines (1) permanent storage funded by an on-chain endowment that pays Filecoin miners so you “pay once, store forever,” (2) threshold-crypto access control where each file has its own key, sharded across 5 nodes with 3-of-5 recovery, and (3) a unified SDK (JS & Python) plus web app/CLI. Files are encrypted client-side before upload, and decryption can be token-gated by on-chain logic (NFT ownership, token balances, timelocks, or pay-to-unlock). Current users include Eternal AI (open-source model hosting), Ocean (data marketplace), large-scale NFT storage, and Webhash (ENS sites served from Lighthouse). On top of this, 1mb.io turns data into an asset. Creators deploy a data coin (Sepolia testnet or mainnets like Base/Polygon/VeChain/World Chain), encrypt & host datasets on Lighthouse, set contribution/reward rules, and optionally trade the coin via a built-in Uniswap integration. Examples: a Ride-Sharing DAO paying Uber users who privately prove ride histories via ZK-TLS (Reclaim/Opacity); Pantry Points paying Zomato users for order data; and Miles, an AI augmentation engine where contributors upload real images/maps, pick conditions (e.g., “heavy rain”), and receive coins while an agent generates synthetic data to enlarge the dataset. The live workshop showed: uploading (plain/encrypted), API key creation, SDK calls for upload, uploadEncrypted, share/revoke access, and token-gating checks; then the data-coin creation flow (naming, chain, vesting, lock asset like USDC). Hackathon guidance: just storing on Lighthouse is good, but to be prize-competitive you should launch a data coin on 1mb.io, encrypt/token-gate access, and use the coin in your protocol’s flows (payments, contributor rewards, gated dashboards). Lighthouse doesn’t supply AI models (bring your own); data verification is up to builders (e.g., ZK proofs), and the market will reward higher-quality coins/datasets. SDKs are framework-agnostic, so you can integrate with OpenAI/agents/MCP, etc. 00:10 What Lighthouse solves (permanent storage, secure access, unified SDK) 02:27 How permanent storage works (on-chain endowment → Filecoin miners) 02:54 Threshold-crypto access control (per-file keys, 3-of-5 shards) 04:36 Token-gated decryption via on-chain logic (NFTs, tokens, timelocks, paywalls) 05:35 Who’s using it (Eternal AI, Ocean, NFT storage, Webhash) 06:38 Why 1mb.io (monetize private/siloed data; reward users/agents) 08:10 Data-coin flow (deploy coin, encrypt/upload, reward contributors, DEX trading) 09:06 Stack view (Lighthouse base + 1mb layer + dataset marketplaces) 10:47 Example verticals (chat history, loyalty, maps; synthetic data generation) 15:03 Live: upload (plain/encrypted), API key, SDK usage 17:31 Networks supported & token-gating docs 17:57 Live: create a data coin (chain, vesting, lock asset) 20:31 Live app: Miles synthetic data agent (rewards per image) 21:52 Live app: Pantry Points (ZK-TLS + Zomato orders → rewards) 23:22 Q&A: how to qualify for bounties (launch a data coin, integrate gating/payments) 27:53 AI model sourcing (BYO), data verification (ZK proofs), framework compatibility _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 💻 ETHOnline 2025 This workshop is specifically for ETHOnline 2025, a 21-day hackathon held October 10 - 31, 2025, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem! _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ✅ Follow Lighthouse X: https://x.com/LighthouseWeb3 ✅ Follow ETHGlobal X: https://x.com/ETHGlobal​ Warpcast: https://warpcast.com/ethglobal Website: https://ethglobal.com YouTube: https://www.youtube.com/c/ETHGlobal _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _Are you interested in Ethereum development and entrepreneurship?_ 👉 Sign up for the next ETHGlobal event: https://ethglobal.com/events 🎁 Get exclusive access and perks with ETHGlobal Plus! https://ethglobal.com/plus 📣 Want us to throw an event in your city?
