METHOD AND APPARATUS FOR MANAGING INFORMATION ABOUT MEASUREMENT DEVICE

A method and apparatus for managing information about a measurement device, which is applied to a network system including a plurality of blockchains that includes a first blockchain and a second blockchain, data sender node devices and data manager node devices, the method can comprise receiving a cross-chain request from a data manager node device for device state information associated with a measurement device stored in the first blockchain, wherein the data manager node device is a node device for a second blockchain, verifying, in response to the cross-chain request, that a data manager associated with the data manager node is authorized to manage the device state information, obtaining a target depository transaction corresponding to the device state information, wherein the target depository transaction is stored on the first blockchain and was previously saved to the first blockchain by a data sender node device, wherein the data sender node device is a node device for the first blockchain, and performing management of the device state information based on the target depository transaction.
