If the adaptation parameter is smaller than the preset adaptation parameter threshold, the corresponding derivative knowledge carrier data is insufficient in originality degree and is not suitable for being written into the blockchain. Determining the adaptation parameters and the relevance parameters by knowledge content repetition information may be done by:
