1. A computer-implemented method comprising:
populating, based on input to a front-end portal, a plurality of fields including a plurality of attributes and a serial number of a device;
hashing each of the plurality of fields;
hashing a contiguous sequence of the hashed plurality of fields to generate an asset management identification key;
transmitting the asset management identification key to a blockchain;
authenticating the device using the asset management identification key transmitted to the blockchain;
updating one of the plurality of fields with information indicating a liveness of the asset management identification key, wherein the updating comprises updating an auxiliary field of the asset management identification key to indicate that the asset management identification key is archived;
re-hashing the updated one of the plurality of fields;
re-hashing the contiguous sequence of the hashed plurality of fields including the re-hashed updated one of the plurality of fields to generate an updated asset management identification key; and
superseding the asset management identification key with the updated asset management identification key in the blockchain, wherein the superseding causes the asset management identification key to be archived in the blockchain.
