## Description

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
