0000 Disclosed herein are embodiments for a record-level encryption scheme. A data visibility control platform may facilitate record-level encryption between a data owner device and a requester device, requesting access to the encrypted record. The record may contain sensitive and/or confidential information of the data owner. The data owner may directly control the visibility of the record via the data visibility control platform. The data visibility control platform may use a combination of private and public cryptographic keys associated with the data owner and requester to provide record-level encryption. An embodiment may include record keys used to encrypt records being stored by a records database managed by a data intermediary. The record key may be encrypted using the public key of the data owner and stored on a blockchain. Access to the record key stored on the blockchain is controlled by the data owner.

A shared ledger operated by a group of network participants according to a set of consensus rules manages and resolves subrogation claims between a clamant and a defendant. Evidence regarding the value of the subrogation claim is sent to the shared ledger by entities involved in the claim such as sending to a smart contract deployed on the shared ledger. The parties to the subrogation claim may supplement evidence and settlement proposals on the blockchain by broadcasting a transaction or sending data to the smart contract. Once the claim is resolved, the parties may settle the subrogation payment off-chain or may transact a token having value on the chain. A subrogation smart contract may be programmed to release funds under certain conditions including holding a bond by a claimant and/or upon final resolution of the subrogation claim.

0000 Some aspects relate to technologies for automatic crypto wallet balancing. The crypto wallet balancing can involve rebalancing a first crypto wallet to reduce its balance. This can include monitoring a total value of the first crypto wallet over a time period, where the first crypto wallet is owned by a first user and associated with a first blockchain account on a first blockchain. A rebalance trigger event is detected based on the total value of the first crypto wallet exceeding a maximum threshold value for a threshold amount of time during the time period. Responsive to the rebalance trigger event, a smart contract on the first blockchain is executed, causing: generation of a transaction block transferring digital assets from the first blockchain account to a second blockchain account associated with a second crypto wallet owned by the first user, and addition of the transaction block to the first blockchain.

0000 Methods, systems, and devices for digital token management are described. Techniques described herein may enable the generation of a key pair associated with the application that is temporarily valid without prompting the user to authenticate each transaction individually. For example, the user may validate a key pair to be used for transactions for a period of time, for an amount of crypto token, for a quantity of transactions, and the like. Accordingly, the user may perform purchases using the key pair without exiting the application. In some examples, the key pair may be generated by the application or by an SDK associated with a blockchain wallet application. The key pair may be signed by each of the user, the client application, and one or more on-chain smart contracts, which may prevent the key pair from being used for purchases that are not approved by the user.

Resumen de: US20260149744A1
Hardware and software resources are load balanced when processing multiple blockchains. As more and more entities (whether public or private) are expected to generate their own blockchains for verification, a server or other resource in a blockchain environment may be over utilized. For example, as banks, websites, and retailers issue their own private cryptocoinage, the number of financial transactions may clog or hog networking and/or hardware resources. A blockchain load balancing mechanism thus allocates resources among the multiple blockchains.

0001 The quantification and persistence of imaged food includes the acquisition of imagery by an optical sensor of a digital camera such as that included within a smart phone. The optically sensed imagery is then loaded into memory and a food portion can be identified therewithin. Subsequently, a food waste value is computed of the identified food portion and the food waste value is encapsulated within a digital artifact to be written into the memory. Finally, the digital artifact is uploaded into a secure ledger entry from over a computer communications network, such as an entry in a blockchain ledger.

0001 The invention relates to distributed ledge technologies such as consensus-based blockchains. methods for causing an injection of a serialized previous transaction into a locking script are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network, with the first transaction including a first script. The first script, as a result of being executed, causes the node to at least obtain a first set of field values corresponding to the first transaction and obtain a second set of field values corresponding to a particular transaction. A second transaction is obtained, with the second transaction having been validated and including a second script. The second script, as a result of being executed, causes the node to at least obtain the first set of field values and the second set of field values of the particular transaction supplied as a result of execution of the first script, extract a transaction identifier from the first set of field values, and determine, based at least in part on the second set of field values, that the particular transaction corresponds to the transaction identifier. The first transaction is validated by executing the first script and the second script.

Resumen de: US20260141361A1
According to a present invention embodiment, a system acquires an onchain asset of a blockchain for a user. The onchain asset corresponds to an offchain asset of the user and indicates ownership of the offchain asset. The onchain asset is transferred to one or more recipients on the blockchain. Transferring the onchain asset changes an ownership indication on the blockchain for the offchain asset to a corresponding recipient. Transfer of the offchain asset is deferred until requested by a recipient possessing the onchain asset. The offchain asset is transferred to the recipient in response to a request from the recipient to transfer the offchain asset. Embodiments of the present invention further include a method and computer program product for transferring assets of a computer environment in substantially the same manner described above.

Certain aspects of the present disclosure provide techniques for for securely processing transactions on a blockchain or other distributed computing system. An example method generally includes receiving a request to execute an action in the distributed computing system. Based on the request, a set of systems in the distributed computing system are identified to approve the request to execute the action. Generally, each system in the set of systems has a weight associated with the system. Approval is requested from systems in the set of systems for execution of the request to execute the action in the distributed computing system. The action is executed in the distributed computing system based on a cumulative weight of approving systems from the set of systems exceeding a threshold weight for approval.
