0000 A vault-based lottery system for exclusive music streaming provides controlled platform access while ensuring fair artist compensation. The system generates unique vault codes for users who enter a daily lottery for membership, with machine learning dynamically adjusting lottery odds based on engagement metrics. Superfan members bypass the lottery, gaining immediate access to exclusive artist content, pre-release music, and priority participation in live sessions. The platform implements blockchain technology to authenticate music, verify content ownership, and execute transparent artist compensation through smart contracts at rates significantly higher than traditional streaming services. Artists control release scheduling and can issue lottery bypass passes to dedicated fans. A fan-driven discovery algorithm prioritizes recommendations based on superfan engagement rather than purely algorithmic methods. The integration of machine learning optimization with blockchain verification creates a sustainable ecosystem benefiting both artists and dedicated fans while maintaining content exclusivity.

A blockchain-based deep neural network model federated recombination method includes constructing a consortium blockchain for model federated recombination; configuring a smart contract for the model federated recombination; storing data in a model federated recombination process; training a source model of a model training party, and providing the source model to a model recombination verification party for federated combination; performing model federated recombination, wherein the model recombination verification party performs federated recombination on the source model to obtain a target model; and calculating a contribution value of the model training party. For the reusability of a deep neural network model and the finiteness of computing power and data during single-node user model recombination, multi-node model federated recombination is performed. For the data security and privacy in a federated process and the mutual distrust between multiple nodes in federation, a Hyperledger Fabric-based consortium blockchain and a smart contract are constructed.

Techniques are described relating to the ownership and management of digital assets that are represented by non-fungible tokens (or “NFTs”) on a blockchain. Trusted hardware is used to enable encrypted digital assets to be consumed solely by the owners of the encrypted digital assets and further to enable the transfer of ownership in the digital asset to a new owner using a blockchain. An owner of a digital asset controls access to and consumption of the digital asset via the trusted hardware to which the asset is cryptographically bound. The legal ownership of the digital asset is represented on the blockchain via an NFT. When an NFT changes ownership (e.g., when it is sold to a new owner) on the blockchain, a secure hardware-to-hardware asset transfer protocol is used (off-chain).

Approaches are described for secure identity verification using blockchain technology. A configuration record for a user's identity attributes is obtained. The configuration record is used to evaluate and verify various identity elements through cross-referencing with authoritative sources. Based on the configuration record, identity tokens (KYbits) are generated using cryptographic techniques and stored on a blockchain ledger. These KYbits encapsulate verified identity information and can be utilized in verification processes without disclosing sensitive personal data. The identity tokens enable secure and privacy-preserving transactions across various platforms, ensuring compliance with data protection regulations and enhancing user control over personal identity information.
