Block chain-based operation and maintenance data management method and apparatus, and electronic device

The invention discloses an operation and maintenance data management method and device based on a block chain and electronic equipment, and relates to the field of block chains. The method comprises the following steps: receiving data processing requests sent by a plurality of block chain nodes, and determining a target processing link corresponding to the data processing requests according to data types in the data processing requests; generating a target transaction corresponding to the data processing request according to the target processing link, and determining a target processing mode corresponding to the target transaction according to the transaction type of the target transaction; and processing the target transaction according to the target processing mode to obtain a data processing result, and returning the data processing result to the plurality of block chain nodes. The technical problem that in the prior art, when operation and maintenance data are managed by using a block chain technology, t
