NFT.Storage is a long-term storage service designed for off-chain NFT data (like metadata, images, and other assets) for up to 31GiB in size per individual upload. Data is content addressed using IPFS, meaning the URI pointing to a piece of data (“ipfs://…”) is completely unique to that data (using a content identifier, or CID). IPFS URLs and CIDs can be used in NFTs and metadata to ensure the NFT forever actually refers to the intended data (eliminating things like rug pulls and making it trustlessly verifiable what content an NFT is associated with).

Lit is a decentralized compute, encryption, and access control network powered by threshold cryptography.

With Lit, developers can automate signing, reading, and writing data to web3 decentralized networks like Ethereum and IPFS. Additionally, data can be private in these open web applications and only decrypted by authorized parties with Lit access control. 

Lit offers two products, Prograblem Key Pairs (PKPs) and Decentralized Access Control. There is one bounty for each product!
