/*
To change the max block size, all that needs to be updated is the #define _MAX_BLOCK_SIZE in utils.h
However, doing that without any other changes will allow forking non-updated nodes by creating a larger block. So, make sure to height activate the new blocksize properly.
Assuming it is 8MB, then:
#define _OLD_MAX_BLOCK_SIZE (4096 * 1024)
#define _MAX_BLOCK_SIZE (2 * 4096 * 1024)
change the body of if:
{
if ( height < saplinght+1000000 ) // activates 8MB blocks 1 million blocks after saplinght
return(_OLD_MAX_BLOCK_SIZE);
else return(_MAX_BLOCK_SIZE);
