Load Balancing in Blockchain Environments

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.

PREPROCESSING CRYPTOCURRENCY TRANSACTIONS

Resumen de: WO2026111823A1

Examples predict changes in risk scores in cryptocurrency transactions between potential transacting parties. The system identifies a tentative transaction between the sender and receiver on a cryptocurrency blockchain. The system builds a receiver transaction tree based on cryptocurrency transactions already recorded in the blockchain. The system also similarly builds a sender transaction tree. The system calculates a current risk score of the sender party based on the second transaction tree. The system builds a third transaction tree by adding the first transaction tree into the second transaction tree, thereby simulating the sender party as having transacted with the receiver party. The system then calculates a predicted risk score of the sender party based on the third transaction tree and transmits one or more of the predicted risk score and a change in risk score to the sender party.

BLOCKCHAIN SUBROGATION PAYMENTS

Resumen de: US20260148310A1

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.

Resumen de: EP4749982A2

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.
