Building the data layer for AI I Arpit Bindal, Rishikesh Kale and Abhay U

A three-part workshop on building the data layer for AI across Filecoin-based services. First, Synapse SDK: a full-stack Next.js demo that handles balances, USDFC approvals, on-chain payments, hot storage, and dataset creation—upload a file, fund allowance (approve → transfer → lock), and retrieve via CID. Second, Akave 0³ (S3-compatible) storage: AWS-style buckets, client-side encryption, immutable/versioned objects by default, Reed–Solomon erasure coding, and hackathon tracks (datasets, analytics, backup/recovery). Third, Lighthouse: permanent, encrypted storage with access control; upload via UI/JS SDK, share/revoke conditions; then mint “data coins” (e.g., POP) and reward users. Sample app: prove Amazon order history with Reclaim, verify server-side, store on Lighthouse, and mint POP tokens to users. 00:02 Intro & agenda: Synapse SDK, Akave 0³, Lighthouse 00:31 Prereqs: Filecoin Calibration FIL & USDFC faucets 00:54 Synapse FS-Upload demo app (Next.js full stack) 01:38 Synapse SDK overview & tutorial repo 02:10 Code tour: balances, payments, uploads, dataset hooks 03:08 Payment flow: approve USDFC → transfer → lock allowance 03:35 Running the app; what each tx does 03:59 Checking balances, rate allowance; deposit/increase allowance 04:23 Upload flow: pick file → init storage → connect provider → create dataset 04:41 Confirm on-chain tx; view dataset (CID) & download/retrieve 04:56 Store any data on Filecoin via Synapse SDK 05:21 Akave 0³: what it is (S3-compatible, cheaper, immutable) 05:54 Architecture: SDK → immutable ledger → distributed Akave nodes 06:57 Demo with AWS CLI (S3 endpoint set to 0³ RC2) 08:08 Create bucket; upload file; list objects 09:12 Versioning enabled by default; re-upload to create v2 10:14 Client-side encryption & Reed–Solomon erasure coding 11:28 Hackathon prizes & tracks (datasets, analytics, backup/recovery) 12:30 Starter guide & booth support 12:50 Lighthouse intro: permanent, encrypted, access-controlled storage 13:46 Log in & public upload via dashboard (CID/gateway) 14:12 Encrypted upload (sign, encrypt, then IPFS) 14:36 Create API key for programmatic use 14:58 Docs tour: upload (JS/API/CLI), uploadEncrypted, share/revoke, token conditions 15:58 Making data valuable: “data coins” as tickets for private data 16:18 Create a data coin on 1membb.io (POP example) 17:19 Chain, vesting, and locking assets; submit & programmatic script 18:05 Hackathon ask: users upload private data, get rewarded 18:31 Sample app (POP Rewards): prove Amazon orders with Reclaim 19:06 Flow: user proof → server verifies → upload to Lighthouse → mint POP 19:26 Wrap-up: tokenize datasets, attach value, earn from your project _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *ETHGlobal New Delhi* This workshop is specifically for ETHGlobal New Delhi, a 3-day hackathon held September 19-21 at the India International Convention & Expo Centre, 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!
