Embodiments provide a blockchain-implemented database overlay and indexing mechanism. In one embodiment, records in the database are associated via the overlay to respective unspent outputs in transaction(s) on the blockchain. Each output comprises a locking script that specifies which keys can be used to spend the output to a further transaction. When a user wishes to access a given record in the database, the further (spending) transaction is generated and sent to the blockchain network. The further transaction comprises an unlocking script that provides the required key(s) to meet the conditions of the locking script, otherwise the blockchain's consensus mechanism will not allow spending of the output and access to the record will be denied. If, however, the requirements are met then the output is spent and the access request is deemed authorized. In this way, the consensus mechanism provides an improved permission control and user authorization solution for a database. When the output is spent by the further transaction, the overlay is updated to associate the record with the spending transaction. A transaction log may also be provided to enable swift and efficient regeneration of the database should it be required.

A system, method, and non-transitory computer-readable medium trace repurposing of targeted artificial intelligence systems. Storage media hold a training dataset sourced at least in part from a target artist, where a target artist configuration characterizes the artist's work, together with a provenance wrapper containing a provenance vault accessible by a provenance private key, the vault holding a creator's list. One or more processors train an artificial intelligence system on the dataset to produce a trained version that constructs outputs satisfying the target artist configuration, make the trained version available, provide access to it, and validate that new outputs from repurposing it satisfy the configuration. The creator's list authenticates the new outputs. A parent non-fungible token assigned to the trained version traces back from offspring tokens of downstream digital assets, including outputs of further-trained versions combining additional artist configurations and outputs deployed via a blockchain network.

0000 A system and computer-implemented method for facilitating communication and interoperation between heterogenous networks in an ecosystem of networks is described. Distributed ledger technology is used to provide a first network among the ecosystem of networks with a permissionless core, such as a blockchain. At least a subset of the networks are blockchain networks. The ecosystem comprises regulated and/or unregulated networks that are linked through their engagement with the permissionless core of the first network. Transactions spanning independent networks in the ecosystem benefit from a combination of regulatory oversight and decentralized, algorithmically safe permissionlessness. Transactions between distinct unregulated networks (such as different blockchain networks) and transactions between regulated and unregulated networks (such as between central currency markets and cryptocurrency) are each facilitated with no trusted intermediary.

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).
