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.

Artifact origination and content tokenization

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.
