Bitcoin XT released with expanded block size limit
This indicates to the rest of
the network that you support larger blocks.
When 75% of the blocks are new-version blocks, a decision
has been reached to start building larger blocks that will be rejected by Bitcoin Core nodes.
If the hard fork occurs and you are still mining with Bitcoin Core, your node will reject the first new block
that is larger than one megabyte in size.
Soft limit: Like Core, Bitcoin XT supports configuring the maximum size of blocks to mine.
your node will not create blocks larger than the limit, although it will still accept them.
