Resumen de: US2024321416A1
Healthcare transaction validation systems and methods are presented. Healthcare transactions associated with a stakeholder are compiled into a chain of healthcare transaction blocks. The chain can be considered a chronicle of person's healthcare path through life. When a transaction is conducted, the corresponding healthcare parameters (e.g., inputs, outputs, clinical evidence, outcomes, etc.) are sent to one or more validation devices. The devices establish a validity of the transaction and generate a new block via a proof-of-work principle. Once the new block has been calculated it can be appended to the stakeholder's health care blockchain.

Disclosed is a secure and distributed system for storing and consuming software bill of materials (SBOM). The system allows software publishers to create a software component and generate an SBOM that describes its dependencies. A web API then securely stores the SBOM on a distributed file system and publishes a hash of the SBOM to a public blockchain. When the software component is updated, a new SBOM is generated, and a signed hash of the new SBOM is stored in a new node on the blockchain. This preserves the history and auditability of the application's SBOMs. Third parties may query the web API to obtain the SBOM while ensuring the integrity and provenance of the information.

The present disclosure provides weight based slotted synchronous blockchain client network. Conventional blockchain consensus protocols heavily rely on synchrony assumptions of the underlying network. However, little attention has so far been given to similar assumptions on blockchain client networks. Such assumptions would be useful in deriving bounds on confirmation times of transactions through the blockchain protocol. To overcome the challenges of the conventional approaches, the present disclosure provides a weight based slotted synchronous blockchain client network. The blockchain client network of the present disclosure is slotted, wherein at most one transaction is submitted in each slot by one of the client nodes. Further, there exists a notion of synchrony in the peering between the client nodes and the blockchain nodes. In an embodiment, for each submitted transaction, there is an upper-bound on the number of slots on the reception of the said transaction at an arbitrary blockchain node.

Resumen de: US2024320663A1
A blockchain system secures transaction workflows. The blockchain system includes a first node associated with a first party to a transaction and a second node associated with a second party to the transaction. The first node receives transaction data for the transaction. The first node generates a block for the transaction. The block includes the transaction data, a hash generated using the transaction data, and a hash of a prior block in a node data store of the first node. The first node sends the block to the second node and receives an indication that the second node has verified the block. The first node stores the verified block in the node data store. The first node may enable execution of the transaction after the block has been verified by all nodes involved in the transaction.
