1![Docker build](https://github.com/usetech-llc/nft_parachain/workflows/Docker%20build/badge.svg)23# NFT Parachain45## Project Description67The NFT Pallet is the core of NFT functionality. Like ERC-721 standard in Ethereum ecosystem, this pallet provides the8basement for creating collections of unique non-divisible things, also called Non Fungible Tokens (NFTs), minting NFT of9a given Collection, and managing their ownership.1011The pallet also enables storing NFT properties. Though (according to ERC-721) NFT properties belong to logic of a12concrete application that operates a Collection, so purposefully the NFT Tracking Module does not have any knowledge13about properties except their byte size leaving application logic out to be controlled by Smart Contracts.1415The NFT Chain also provides:1617-   Smart Contracts Pallet and example smart contract that interacts with NFT Runtime18-   ERC-1155 Functionality (currently PoC as Re-Fungible tokens, i.e. items that are still unique, but that can be split19    between multiple users)20-   Variety of economic options for dapp producers to choose from to create freemium games and other ways to attract21    users. As a step one, we implemented an economic model when a collection sponsor can be set to pay for collection22    Transfer transactions.2324Wider NFT Ecosystem (most of it was developed during Hackusama):2526-   [SubstraPunks Game hosted on IPFS](https://github.com/usetech-llc/substrapunks)27-   [NFT Wallet and UI](https://uniqueapps.usetech.com/#/nft)28-   [NFT Asset for Unity Framework](https://github.com/usetech-llc/nft_unity)2930Please see our [walk-thorugh instructions](doc/hackusama_walk_through.md) to try everything out!3132## Hackusama Update3334During the Kusama Hackaphon the following changes were made:3536-   Enabled Smart Contracts Pallet37-   Enabled integration between Smart Contracts and NFT Pallet (required special edition of RC4 Substrate version)38-   Fixed misc. bugs in NFT Pallet39-   Deployed NFT TestNet. Public node available at wss://unique.usetech.com, custom UI types - see below in this README.40-   New Features:41    -   Re-Fungible Token Mode42    -   Off-Chain Schema to store token image URLs43    -   Alternative economic model44    -   White Lists and Public Mint Permission45-   Use example: [SubstraPunks Game](https://github.com/usetech-llc/substrapunks), fully hosted on IPFS and NFT Testnet46    Blockchain.4748## Application Development4950If you are building an application that operates NFT tokens, use [this document](doc/application_development.md).5152## Building5354Building NFT chain requires special versions of Rust and toolchain. We don't use the most recent versions of everything55so that we can keep the builds stable.56571. Install Rust:5859```bash60curl https://sh.rustup.rs -sSf | sh61sudo apt-get install libssl-dev pkg-config libclang-dev clang62```63642. Remove all installed toolchains with `rustup toolchain list` and `rustup toolchain uninstall <toolchain>`.65663. Install install nightly 2021-03-01 and make it default:6768```bash69rustup toolchain install nightly-2021-03-0170rustup default nightly-2021-03-0171```72734. Add wasm target for nightly toolchain:7475```bash76rustup target add wasm32-unknown-unknown --toolchain nightly-2021-03-0177```78795. Build:80```bash81cargo build82```8384optionally, build in release:85```bash86cargo build --release87```8889## Run9091You can start a development chain with:9293```bash94cargo run -- --dev95```9697Detailed logs may be shown by running the node with the following environment variables set:98`RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev`.99100If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet with two101validator nodes for Alice and Bob, who are the initial authorities of the genesis chain that have been endowed with102testnet units. Give each node a name and expose them so they are listed on the Polkadot103[telemetry site](https://telemetry.polkadot.io/#/Local%20Testnet). You'll need two terminal windows open.104105We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at106`/tmp/alice`. The bootnode ID of her node is `QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN`, which is generated from107the `--node-key` value that we specify below:108109```bash110cargo run -- \111  --base-path /tmp/alice \112  --chain=local \113  --alice \114  --node-key 0000000000000000000000000000000000000000000000000000000000000001 \115  --telemetry-url ws://telemetry.polkadot.io:1024 \116  --validator117```118119In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database120stored locally at `/tmp/bob`. We'll specify a value for the `--bootnodes` option that will connect his node to Alice's121bootnode ID on TCP port 30333:122123```bash124cargo run -- \125  --base-path /tmp/bob \126  --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN \127  --chain=local \128  --bob \129  --port 30334 \130  --telemetry-url ws://telemetry.polkadot.io:1024 \131  --validator132```133134Additional CLI usage options are available and may be shown by running `cargo run -- --help`.135136## Run Integration Tests1371381.
