Project Overview πŸ“„β€‹

As we all know, transaction fees is very high in Ethereum-based blockchains or apps, which limits particularly frequent actions. In polkadot system, for the consideration of redundant data on the chain, there is a very ingenious account system to collect useless account.

With the development of blockchain ecology and application, due to large amount of data generation, use and dissemination in the reality, and most of us care less of the owner of the data.

Now, it's time to limit/collect junk data on the blockchain. DNFT is developing an independent Substrate-based blockchain, which will help improving the right confirmation, circulation and privacy protection of data.


DNFT includes five key components: DataNFT, DataStorageWithTax, DataSwap, DAO Governance and AI-Kit. The whole system provides the generation, storage, exchange, sharing, dissemination of data. Through the data ETL and data label annotations, we're creating a data framework between personal data and AI models.

Project Details​




NFT is a good way to describe data info, through the NFT, it's easy to make the securitization of data and assets. DNFT adopts ERC721 & ERC1155 protocol.


Unlike one time charge when storing, storage tax will be continuous charged when holding NFT assets.When NFT holders have not charged tax in time, NFT will be collected and to be auctioned. Anyone who wins the auction, will continue to pay the tax.


It is an exchange that provides conversion of different synthetic assets and data.

DAO Governance

When NFT under unpaid tax are into the collection pool, the DAO will be responsible for the auction, the auction price will be used to DAO Governance, and NFT with failed auction will be burned.


Through the data ETL and data label annotations, we're creating a data framework between personal data and AI models. We will create an AI-friendly mechanism for NFT generation.

2a.Pallet_nftComplete the development of pallet_nft, realize the ERC1155 standard and integrate existing ERC721 standard(eg.
2b.Pallet_taxComplete the development of pallet_tax and realize the storage tax and collection mechanism
2c.Pallet_swapComplete the development of pallet_swap and realize the NFT swap mechanism
2d.Pallet_daoComplete the development of pallet_dao and realize the governance mechanism
3.Front EndComplete the development of the basic interactive page in vue,and the interface will be available in chinese as well as english
4.Docker ImageWe will provide a dockerfile to demonstrate the full functionality of our chain

Future Plans​

  • We will improve storage mechanism.
  • We will integrate Cross-chain mechanism, we're ready to become a parachain of Polkadot.
  • We will integrate EVM module into DNFT Chain to support Ethereum System.
  • We will implement more type of auctions like lottery auction, social verified auction, etc.

Additional Information​

Our project, the MVP demo has won the Second Prize in Substrate hackathon hosted by DoraHacks in Hangzhou,China on December 20, 2020, which attracted a lot of media attention in China.

In the current implementation, we did a Simple implementation, including NFT generation, NFT trade, NFT owner tax & collection in a fixed blocknumber. Most of them were just a fast & simple implementation for the Substrate hackathon.

As methioned in Milestone 1, we will complete and expand the original intention, 1.pallet_nft, we will realize the ERC1155 standard and integrate existing ERC721 standard, rather than a simple generation. 2.Pallet_tax, we will set a customized tax-set stanard towards different NFT colletcions, rather than a simple All-The-Same solution. 3.Pallet_swap, we will add auction, dex, rather than a simple transfer. 4.Pallet_dao, we will add a governance mechanism to lanch proposals.
