What is the max value which we can set for the block size and metadata size as controlled by the below parameters :-
1. maximum-block-size (which is 1M by default)

The maximum-block-size can go up to 1000000000 (1 GB) and the max-std-op-return-size can go up to 8388608 (8 MB). You can see all these limits in your params.dat file.
