Blockchain-based federated data discovery and sharing
Distributed ledger-based federated data discovery and sharing may be implemented by soliciting one or more discoverers to serve a federated data discovery request. A discovery solicitation may include a discovery proposal, indicating the data type(s) to be discovered by the solicited discoverer(s), the organization(s) that may provide the data type(s), the performance parameter(s), and/or the service fee(s). A discovery proposal may be updated, for example, based on a negotiation. An (e.g., acknowledged/agreed) transaction may be provided to a distributed ledger node. A smart contract may be generated for the federated data discovery request. Notification(s) about triggering the smart contract may be provided to the one or more discoverers. A discovery result responsive to the federated data discovery request may be received based on performance of the discovery task(s) with the organization(s) by the discoverer(s).
