摘要： In various embodiments a device can be configured to implement a distributed ledger capable of immutably recording state data to tokens. In an embodiment a device includes a network interface, memory, and a processor. The processor can be configured to obtain a token including an access policy. The access policy can include a set of access rights. The processor can be further configured to render the token description, receive a user input, and initiate an action based on the token description and the user input. The action can include accessing the content using the access policy. The processor can be further configured to generate a transaction record, and to broadcast the transaction record, the transaction record configured to be incorporated into a ledger entry. The ledger entry capable of being used to compute a challenge for securely adding the ledger entry to a distributed ledger using a cryptographic system.
