# DFINITY Grant

In 2023 a grant from the [DFINITY foundation](https://dfinity.org/) funded our in-depth investigation of the functionality that NFTs can utilize on the Internet Computer Protocol (ICP) compared with other blockchain protocols like Ethereum and Solana. 

To increase the update of correct metadata formatting across ICP we set out below the most common metadata format standards for other blockchains.

We also implement rarity calculations for several PFP collections on the ICP, to highlight the confusion caused by. These calculations closely follow the [academic paper](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4242042) we have written on this subject. 

We have created open-source libraries that can be used for:

* [rust version](https://github.com/OutRankNFT/OutRank-Rarity/blob/main/rarity_math_code_rust.rs) 
* [python version ](https://github.com/OutRankNFT/OutRank-Rarity/blob/main/rarity_math_code_python.ipynb)
* [ICP metadata retreiever ](https://github.com/OutRankNFT/OutRank-Rarity/blob/main/script%20for%20fetch%20data%20from%20canister.rs)
* [ICP on-chain calculator ](https://github.com/OutRankNFT/ICP-RarityCalculator)

We have also created open data repositories for access to our analysis:

* [ICP NFT Data and empirical results](https://github.com/OutRankNFT/ICP-Rarity-data)

Or users can use our on-chain rarity calculator directly: 

* [Onchain calculator ](https://w4ulz-kiaaa-aaaap-qbsma-cai.icp0.io/?)

Any questions on any of the above please reach out to @toby\_meller on Telegram.

### ICP Rarity initiative 

OutRank aims to share our work on rarity calculations and metadata format to improve the NFT market efficiency on the ICP blockchain. Our partners:
