I can't figure out what you are taking about. But i guess that you are training about bitcoin block size, but as a programmer 1MB size is not a big size for me. Since bitcoin have millions of block so obviously that would sum up a huge number.
OP talk about technology behind the bitcoin is called blockchain,Block that contains all new transactions on the bitcoin network will be confirmed at every 10 minutes, and now has been limited to 1MB of information in one block,op does not explain in detail thread meant just write 1 MB to big.
