First, as I can't stop myself from saying this....
Bank of China Moves to Patent
Something from China patenting something is just ....

The masters of copy paste are doing patents now.
The application details that, instead of letting a new block store transactions from its previous one, a data compressing system could be used to pack transactions from multiple blocks into what the patent calls a "data block."
For instance, as the patent application describes, once the system receives a request to compress transactions from block 1 to 1,000, it causes a new data block to be formed and temporarily hosted on a different storage system. The system will then run the packed data through a hash function with a hash value.
There is nothing that innovative on this.
It's a basic and rather crude method of pruning by removing the header.
