Blockchains (smart contracts, distributed ledgers) and rights management broadly construed are the themes of today's Spotlight Applications. Assigned to Kyndryl, the first application discloses techniques for securely accessing self-sovereign data via a bot-chain ledger. Assigned to KPMG, the second application discloses techniques for providing modular and configurable smart contracts for blockchain applications.

Abstract
An approach for securely accessing self-sovereign data via a bot-chain ledger may be provided. A bot may request access to a piece distributed data at a bot-chain client. A bot registry service may validate the requesting bot is registered with the bot-ledgering client. The bot-ledgering client may generate a token for the requesting bot and provide the identity of a data bot with permission to access the piece of distributed data. A data bot may request to read the piece of distributed data at the bot-ledgering client. The bot-ledgering client may verify the data bot is registered with the bot-chain. The bot-ledgering client may generate an access token and send it to the data bot.

Abstract
The invention relates to systems and methods for providing modular and configurable smart contracts for blockchain applications. The smart contracts may be utilized to retain all transaction attribute values in a world state database of the blockchain-implemented ledger. The systems and methods can further provide for dynamically configurable metadata and rules for transaction attributes recorded on a blockchain transaction log. The metadata and rules corresponding to the transaction attributes may be dynamically updated and applied to the transaction attributes.
