Increasing the maximum block size doesn't necessarily cause an increase. A majority of miners can soft-fork to set the limit lower than the hard limit. Setting the hard-fork limit higher means that a soft fork can be used to adjust the limit in the future. The reference client would accept blocks above the soft limit for wallet purposes, but not build on them. Blocks above the hard limit would be rejected completely. --001a1147efce8d320a0515723afd Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable
