# Open Grant Proposal

* **Project Name:** Starry Protocol
* **Proposer:** [Starry Network](https://github.com/Starry-Network)
* **Payment Address:** 0xe29DE8c6088d241647e6456F8b4755a3D0f7c8B1

## Project Overview :page_facing_up:
### Overview

It is well known that most NFTs are traded either directly or by auction, and the single NFT limit the flexibility of NFTs in some ways.

Splittable NFT will bring liquidity, lower barriers to entry and more possibilities to NFT ecosystem. For example, buying SubNFTs on bonding curve will allow for better pricing of works, while NFTs that are otherwise very expensive can be collected by more people, it is also possible to purchase a group of NFT tokens and contribute to the management of this group of NFTs.

Starry provides some solutions for splittable NFTs, such as: splitting Single NFT into some SubNFTs, splitting Single NFT into some fungible tokens, and splitting a group of NFTs into some fungible tokens and managing them using dao.

### Project Details
The Starry Protocol contains four parts: Pallet_NFT, Pallet_SubNFT, Pallet_EX, Frontend

#### Architecture

**Pallet_SubNFT**

An NFT Wrapper to split NFTs into SubNFTs or fungible tokens, or a set of NFTs into fungible tokens( without DAO). Here is [demo page](https://friendly-mclean-d455eb.netlify.app/splitNFT).

**Pallet_NFTDAO**

Split a set of NFTs into fungible tokens and manage the NFTs in a DAO way, such as adding more NFTs or selling NFTs. Here is [demo page](https://friendly-mclean-d455eb.netlify.app/dao/0).

**Pallet_EX**

exchange NFT (including buying SubNFTs with bonding curve/one price) and send royalties generated by each transaction to the creator. Here is [demo page](https://friendly-mclean-d455eb.netlify.app/nft/1).

**FrontEnd**

Interaction with users. Here is a [demo](https://friendly-mclean-d455eb.netlify.app/)

## Future Plans
- Implementing auction functions (English auction, Dutch auction).
- Add comments, favorites and data analysis to Starry to improve the Starry ecosystem.
- Simplify the usage process and make NFT more friendly to newcomers.
- Implementing cross-chain transmission NFT.
- Lead the community to hold online exhibitions and comment on good NFT works, using tokens to promote these beneficial behaviors.

## Additional Information :heavy_plus_sign:

- What is the difference between SubNFT and Erc-1155?

erc-1155's multiple NFT is Semi-fungible tokens, these tokens use same token_id.

SubNFT splits single NFT into different NFTs, each SubNFT has its own token_id. As a result, subNFT is even rarer and suitable as a collector's item.

For example, we can use Semi-fungible tokens to create general admission tickets for a concert, and then use SubNFT to create commemorative tickets.



- What is the difference between SubNFT and Erc-721?

subNFT is also erc-721 token
