IPFS File Storage

Challenges with datastorage for NFTs

  1. The actual NFT assets cannot be stored on the blockchain due to very high costs. Solution: Storing the asset off-chain

  2. The key (link) to the content must be trully unique and immutable. Solution: The key is genrated based on the content (as content hash) using Contenet Addressing.

  3. The content must be immutable and persistable forever. Solution: using Interplanetary File System (IPFS) to store the asset in the decentralized way. Improve the content persistance through Filecoin which uses Proof-Of-Replication to ensure the availability of the client's origial data, and Proof-Of-Spacetime to ensure that the data is stored continuisly overtime.

NFT.Storage uses Filecoin to store & persist assets on IPFS

Requires account on nft.storage



Update NFT_STORAGE_API_KEY in .env



to upload asset & metadata to IPFS:

node scripts/store-asset.mjs

Testing

  1. Start Hardhat Node
    npx hardhat node

  2. Run the Tests
    npx hardhat test --network localhost --logs
