BLOCKCHAIN OPERATION AUTHORIZATION AND VERIFICATION

Resumen de: US20260012352A1

A system may include a remote server and an on-premises node. The server may receive a first set of parameters defining a blockchain operation. The server may generate an operation payload based on the parameters. The on-premises node may receive the operation payload from the computing server and decode the operation payload to extract a second set of parameters reflected in the operation payload. The on-premises node may compare the second set of parameters to the first set of parameters to determine whether the second set matches the first set. If the parameters match, the on-premises node may sign cryptographically the operation payload and transmit the operation payload to the computing server for the computing server to broadcast the operation payload to a blockchain to carry out the blockchain operation.

SYSTEMS AND METHODS FOR ACCESSING DIGITAL ASSETS IN A BLOCKCHAIN USING GLOBAL CONSENT CONTRACTS

Resumen de: US20260073068A1

A consent block is a type of block that may be stored in a blockchain. Each consent block has an owner and may store an owner consent contract, i.e., a smart contract containing owner-specified access rules that determine who may access data assets that are stored in other blocks of the blockchain and owned by the same owner. The consent block may alternatively store a global consent contract containing global access rules that supersede owner-specified access rules. The consent block also stores a hash value determined from the consent contract and a previous hash value of the block immediately preceding the consent block. The consent contract and the position of the consent block in the blockchain are verifiable from the hash value. Each consent block, once added to the blockchain, becomes part of the immutable record of data stored in the blockchain, and therefore leaves an auditable trail.
