Four Rejuve Token Types

1. The Rejuve ID/Data NFT. This is a unique ID, a distributed identity token, that is associated with every data-contributing member of the Rejuve Network, including individuals, labs, researchers, data modelers, companies, employees, and contractors. It is an ID combined with an NFT. This NFT is different from other NFTs in that it can not itself be bought, but keeps track of permissions to use data through a permission hash that hashes the requester’s RejuveID, a hash of the private data, and the product UID (Unique Identifier) to confirm that permission has been granted for the particular data to be used in particular products.

2. The Rejuve Product NFT. A token consisting of an ERC-721 NFT sharded (fractionalized) into ERC-20 utility tokens, following the Refungible Token Standard (RFT), that are distributed to data owners in proportion to their contribution to a generated product (for example a drug or therapy). pNFTs are minted at a predetermined endpoint (for example at time of patent filing, or suggestion of a lab from a hypothesis generated by Rejuve’sAI). This NFT represents the data contributors' ownership share in the product. Proceeds from the product itself are distributed in the form of RJV tokens to pNFT shard holders in proportion to the amount of shards they hold. One pNFT is minted per product ideation. pNFT shards are distributed to users proportionally based on their contribution to that product, calculated by an AI algorithm. The distribution of these shards is done in batches, wih the first batch distributed to initial data contributors, with other batches distributed after further studies and clinical trials. Once the product reaches a certain stage of maturity where no more data is needed to be contributed, any remaining shards will be burned. Data owners can sell up to 50% of their shards initially, with the other half locked for a period of time, in order to prevent exploitation/assure that they maintain ownership of products made from their data. Rejuve Network will receive a certain portion of all minted pNFTs, and allocate a portion of the tokens earned from its own shard proceeds to a pool to continually fund token rewards that incentivize data contribution.

3. The Rejuve Product NFT coupon. These ERC-1155 tokens are given as prizes to stakers that are in an NFT challenge staking pool at the time that a challenge is solved by a community. They are good for a discount on the product NFT that is made for the challenge winning idea. There are different levels of discount depending on the length of time a staker had stayed in the pool. They are good on the Rejuve marketplace.

4. The Rejuve token (RJV). This is the utility token (ERC-20), a fungible token through which transactions between network members are made, and through which members are given rewards for data contributions. A fixed number will be minted upon network formation. This token will also have governance capabilities as the network matures.
