    摘要： Systems and techniques to facilitate content access within an NFT platform are illustrated. One embodiment includes a method for content security. The method receives a request from a requesting party, wherein the request includes: information about a transaction to be performed, a reference to a token corresponding to the transaction, and an address of a receiving party corresponding to the transaction. The method recovers, from a smart contract associated with the token, at least one address list, wherein: the at least one address list comprises a token banlist, and the token banlist comprises at least one address banned from receiving the token. The method determines whether the address of the receiving party is listed on the token banlist. When the address of the receiving party is listed on the token banlist, the method transmits a transaction rejection to the requesting party.

    摘要： Non-fungible token (NFT) platforms in accordance with various embodiments of the invention are described. In an embodiment of the NFT platform includes storing several tokens, where a token includes several data elements and associated access control settings for accessing the several data elements; identifying a script to execute that is associated with a first token, where the script includes at least one instruction for accessing data from at least one data element of a second token; determining, based on access control settings of the second token, that the first token has particular access rights to the at least one data element of the second token; and executing the script based on the particular access rights of the first token.

    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 are described for implementing blockchain-based content engagement platforms. In several embodiments, the content engagement platform includes a registry service which enables verified content creators to mint Non-Fungible Tokens (NFTs). In many embodiments, media wallet applications enable users to securely store NFTs and/or other tokens on their devices. In a number of embodiments, the media wallet applications collect data concerning media consumed by users and aggregate the media consumption data in a permissioned analytics blockchain. The manner in which the media consumption data is stored can enable users to control permission to access their personal data. In one embodiment, a media wallet is provided that can securely store NFTs, display a user interface through which user instructions concerning data access permissions are received, and cause media consumption data to be written to at least one immutable ledger in conjunction with a set of data access permissions.

    摘要： Systems and techniques to associate tokens with environmentally-conscious activity are illustrated. One embodiment includes a method for associating access rights with an resource. The method encodes information associated with an action as a token, wherein: the token is associated with an resource and a public key; and the token includes access rights to the resource. The method receives, from an entity, a request for access rights to the token, associated with: an identifier for the entity; and a claim that the entity performed the action. The method retrieves audit data, associated with the entity, from a verifier. When the audit data verifies that the entity did perform the action: the method generates a private key that provides access rights to at least one of the token or the resource. When the audit data verifies that the entity did perform the action: the method transmits the private key to the entity.

    摘要： In various embodiments, systems and methods can provide improved security for blockchain wallets by partitioning addresses within the wallet according to roles that those addresses may perform. Addresses can be, in several embodiments, associated with the partitions. Addresses can be associated with partitions according to how the addresses are derived. Addresses can be derived from a master ley and/or an index variable. The index variable can vary according to partition. The master key can be common across the partitions. The partitions can have different access and/or use rights with respect to the digital assets stored in their respective addresses.
