    摘要： The ability to write illegal information or rights holder information into an immutable public ledger is problematic for society. Similarly, the inability to selectively cause funds transfers to be undone currently gives rise to significant abuses. In various embodiments, a processor, can be configured to obtain a ledger entry associated with a distributed ledger. The ledger entry can comprise an assertion authentication value and a reference. Data can be requested based on the reference. When the data is not available, an assertion can be obtained. a result can be generated and then compared. when the result and the assertion authentication value match, a challenge can be computed using a cryptographic system, wherein the challenge is based on the ledger entry. A block that incorporates the ledger entry can be broadcast to securely add the block to the distributed ledger.

    摘要： Systems and methods for automated blockchain-based recommendation generation, advertising and promotion in accordance with various embodiments of the invention are described. A user device in accordance with an embodiment of the invention includes: a network interface; memory; and a processor. In addition, the processor is configured to implement an execution environment that enables: initiation of transactions via an immutable ledger; recordation of events; updating a user profile, where the user profile comprises at least one characterization associated with the user profile; encrypting the updated user profile and securely storing the encrypted user profile; receiving a request to access the encrypted user profile from a process; determining access permissions of the process; and when the process has sufficient access permissions, decrypting the user profile and providing user profile data to the process.

    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.

    摘要： Devices can be configured to broadcast blocks incorporating artifact origination tokens. Devices can include network interfaces, memory; and processors. Processors can be configured to obtain artifact-to-time association elements. Artifact-to-time association elements can include artifact references and timestamps. Timestamps can include references to artifact references. Processors can be further configured to obtain artifact origination tokens. Artifact origination tokens can include artifact-to-time association element, certifier descriptors indicating certifier public keys, and/or certifier digital signatures. Certifier digital signatures can be generated based on certifier public keys and/or artifact-to-time association elements. Processors can be further configured to obtain ledger entries including artifact origination tokens with public keys, compute challenges based on ledger entries, and broadcast blocks incorporating the ledger entries. Blocks can be validated using cryptographic systems to obtain proof based challenges.
