Problem Statement

Helping artists monetize creative work via the decentralized web. Users can buy or sell access to exclusive content hosted on IPFS and Filecoin. The app will generate unique encryption and decryption keys and store them in the encrypted state of a privacy-preserving smart contract on Secret Network.Subgraph https://thegraph.com/explorer/subgraph/padlockapp/padlock.Crypto Domain (needs Unstoppable Extension installed) Test domain (shown during demo): https://testdomain071.crypto Final domain: https://padlock.cryptoPadlock main contract https://ropsten.etherscan.io/address/0x8d1ed3dab2de4622b7ed38bab4a9918256cf7b30Padlock NFT contract https://ropsten.etherscan.io/address/0x82903d9f4fd393d6e47273adb2a11a2ccae03392

Solution

Secret Network for key generation for content encryption/decryption, IPFS and Filecoin for storage (leveraged by Textile’s Powergate using the public http instance for IPFS hosting and Filecoin deal-making), The Graph for indexing, Fleek for hosting, 3Box for managing profiles and storing secret keys and Secret Network credentials, Metamask for Ethereum wallet use, and Pinata for pinning IPFS creations. App is built using Typescript-based React w/ Redux Saga for state management. Ethereum is used as the payment and data layer. There’s also the oracle that’s watching purchases and whitelisting buyers on the Padlock Secret Network contract as well as minting an NFT for each user purchase which acts as a receipt.We also added a .crypto domain for the project at (https://padlock.crypto). You'll need to use the Unstoppable Extension for Chrome to use it.
