Its an NFT based Data Sharing Platform where info can be shared and allowed to be shared and with transferrable ownership
The contract is made just to play around with the ownership of a string. This implementation can be carried for sharing of ownership of any signed document ( obviously cryptographically ) over the public blockchain network.
Contract Deployed in Carthagenet : KT1SmvWyN6npuJXpLYLmu3TpHSkGDh4zEa2F
SmartPy Explorer to Play Around with the tokenizer : https://smartpy.io/dev/explorer.html?address=KT1SmvWyN6npuJXpLYLmu3TpHSkGDh4zEa2F
Features:
MintDataToken : Whenever a new token is to be managed in the smartContract, it can be handled by the admin of the contract.
BurnDataToken : Burning the Data Token when it is not managed by the smartContract anymore, only the admin has the access to do it with the allowance of the original owner.
Transfer : It transfers the owned token data to another user with the tokenID specified
Approve : Owner can approve someone ( Address ) to handle certain asset so they can transfer the
Transfer From : Only approved addresses for a particular asset token can have the ability to transfer from the owner to any other address without actually owing the data token.
Stack used :
- SmartPy for developing Smart Contract.
- ConseilJs for deployment and interaction.
- Tezster Bundle for Local Development with testing.
- **Tezster CLI ** for local Deployment.
