Claim 6:
7. A system comprising:
a processor;
a non-transitory computer-readable storage medium comprising instructions that when executed by the processor, cause the processor to:
receive a cryptographically secure set of chain branches of a blockchain, wherein the set of chain branches comprises a root block and a set of linked leaf blocks, wherein the root block comprises a timestamp and a parent NFT, and a child NFT is nested within the parent NFT,
wherein the parent NFT comprises a smart contract incorporating one or more user preferences, wherein the child NFT comprises the smart contract defining one or more sub-policies for access by a third party,
wherein each chain branch in the set of chain branches records transactions and actions relating to the child NFT and the one or more user preferences associated with parent NFT of the root block, forming a hierarchical data structure between the parent NFT and the child NFT;

determine, using the smart contract, that the child NFT has permission to access information on the parent NFT based on the one or more user preferences and the one or more sub-policies, wherein the child NFT is associated with the third party,
wherein the information accessed is a hierarchy of actions in the hierarchical data structure that are executed, stopped, or started in response to a preceding action in the hierarchical data structure between the parent NFT and the child NFT;

based on the hierarchical data structure between the parent NFT and the child NFT that defines the one or more user preferences for accessing data at each chain branch in the set of chain branches, and the determined permission granting access by the parent NFT to the information, grant, using the smart contract, the child NFT limited access to the information on the parent NFT and revoking access to other information in the hierarchical data structure;
execute, using the smart contract, the preceding action in the hierarchical data structure;
automatically execute, using the smart contract, the hierarchy of actions in response to the executed preceding action for the accessed information;
receive, using the smart contract, an electronic resource from the child NFT for the parent NFT, wherein the electronic resource is based on the executed hierarchy of actions and the one or more user preferences;
transmit, using the smart contract, the electronic resource to a user device associated with the parent NFT;
store the electronic resource on the user device; and
modify, using the smart contract, at least one of the one or more user preferences of the parent NFT or the one or more sub-policies of the child NFT.
