DNFT

New generation cross chain NFT asset protocol for big data + real scenarios， Ready for hacking 🚀

1.Introduce

Substrate Version for DNFT Protocol.

2.Overview of DNFT Protocol

3.Core Module of DNFT Substrate Chain

3.1 DAO

• DAO Account for NFT collection.
• DAO Tax for NFT tax , Our team believes NFT with tax will be beneficial to the proliferation of NFT assets.
• DAO Proposal for NFT tax setting, etc.

3.2 NFT Protocol

• NFT721, a realization of ERC721

• NFT1155, a realization of ERC1155

• NFT2006, an AI-friendly NFT framework, proposed by DNFT Team

  Brief introduction：

  A memorial to deep learning , proposed in 2006, which has brought leaping development to the field of Artificial Intelligence. NFT2006 aims to make an easy adaption to NFT with data/model in AI field.

  Features:

  • Aggregate multiple NFT, package into one，called Collection. It will be friendly for packaging multiple personal data into a big set.

  • NFT fragmentation into Token(ERC20), friendy for huge Dataset ownership(especially for public data), which will friendly support for NFT mining in AMM/orderbook handling.

  • Copyright protection, authorized viewing using ZKP,MPC and other cryptography tricks.(To do)

  • Discussion in EIP with NFT2006.

3.3 NFT Protocol

• Simple Transfer or with a offer(in NFT Protocol)
• Auction(Simple implementation，will be perfect and optimized in the future )
  • EnglishAuction(higher price bidder win the auction)
  • DutchAuction(Price reduction until the winner comes)
  • SealedAuction(To do)
  • DoubleAuction(To do)
  • HabergerTaxAuction(To do)
• OrderBook(Only support NFT2006)
• AMM(Only support NFT2006)

3.4 Usecase

• AI
  • AIData
  • AIModel
• Game(To do)
• Art(To do)

3.5 EVM-Support

• EVM-Support

3.6 Cross-Chain

• XCMP-Support for Substrate-based Cross Chain
• Relay Mechanism for Heterogeneous blockchains Cross Chain (eg. ETH/BSC/Heco)
• NFT Cross Chain Mechanism

4.Build&Run

4.1Build

Install Rust:

curl https://sh.rustup.rs -sSf | sh

Initialize your Wasm Build environment:

./scripts/init.sh

Build Wasm and native code:

cargo build --release

Build Error Handle Refer

4.2Test

cargo test

4.3Run

Purge any existing developer chain state:

./target/release/dnft purge-chain --dev

Start a development chain with:

./target/release/dnft --dev

Start a development chain support outer ip call with:

./target/release/dnft --dev --ws-external

4.4Run in Docker

First, install Docker and Docker Compose.

Then run the following command to start a single node development chain.

./scripts/docker_run.sh

This command will firstly compile your code, and then start a local development network. You can also replace the default command (cargo build --release && ./target/release/dnft --dev --ws-external) by appending your own. A few useful ones are as follow.

# Run Substrate node without re-compiling
./scripts/docker_run.sh ./target/release/dnft --dev --ws-external

# Purge the local dev chain
./scripts/docker_run.sh ./target/release/dnft purge-chain --dev

# Check whether the code is compilable
./scripts/docker_run.sh cargo check
