What happens if the blocksize will be changed ?

[doc12]

Hi,

if Bitcoin will be forked to allow a bigger blocksize, will Multibit HD still be functional ?  Or is an update reqiered in that case ?

It shouldn't make any difference to MultiBit HD if the maximum block size increases.

When MultiBit HD connects to the Bitcoin network it gives the Bitcoin Core/ XT node it is talking to what is known as a bloom filter.
This tells the node 'Hey, don't give me all the transactions, just give me the ones that match this filter'.

Thus if the block size increases the Core / XT node with filter the 2MB / 8MB / whatever MB block down to just the transactions you are interested in.

Of course, it will need to be tested beforehand to make sure.
