Abstract:
Techniques are described for using a distributed ledger system (DLS) to manage transactions such as the trading of assets between entities. In some implementations, a platform provides a mechanism in which multiple institutions can participate in a dark pool for trading assets. The platform employs a DLS to support a dark pool that provides data privacy to the participating institutions, anonymity to the trading entities, data security, immutability, and transparency for auditing and regulatory compliance. Through a dark pool supported by a DLS, multiple institutions can benefit from a shared dark pool, thus increasing the number of parties who can participate in the trading activities, increasing the quantity of assets available to be traded, and increasing the likelihood of matching seller(s) to buyer for a particular trade. The DLS ensures that the information in the dark pool is kept secure and confidential, through homomorphic encryption and/or zero knowledge proof.

Claim (Index 20):
One or more non-transitory computer-readable storage media storing instructions which, when executed, cause at least one processor to perform operations comprising:\n receiving, by a matching service that controls access to a blockchain-based distributed ledger system (DLS) that comprises one or more blockchains and multiple host nodes, offers from a plurality of institutions participating in the dark pool; for each offer, writing, by the matching service, a record to the DLS, the record describing a respective offer; receiving, by the matching service, a request to provide items to a requesting entity, the request being received from a first computing device that is operated by a first institution associated with the requesting entity, and the request indicating a requested quantity of the items to be provided to the requesting entity; in response to receiving the request, verifying that the first institution is authorized to participate in the dark pool; in response to receiving the request, verifying that the first institution is authorized to participate in the dark pool; in response to determining that the first institution is authorized to participate in the dark pool, storing a request record in the DLS, the request record identifying the requested quantity of the items, the requesting entity, and the first institution; searching, by the matching service, the DLS to identify a set of offer records that includes at least one offer record stored on the DLS, each of the set of offer records describing a respective offer that is available within the dark pool to provide items from a respective offering entity associated with a respective second institution that is authorized to participate in the dark pool, wherein the set of offer records are identified based at least partly on:\n i) a correspondence between the requested items and the offered items, and \n ii) a total quantity of the offered items described in the set of offer records being at least the requested quantity of items; and \n communicating, by the matching service, a match notification to the first computing device operated by the first institution and to one or more second computing devices each operated by respective second institutions identified in the set of offer records, the match notification identifying the requesting entity and one or more offering entities identified in the set of offer records, wherein at least one second institution identified in the set of offer records is different from the first institution associated with the requesting entity.
