Previously, IBFT only validated the header of the block on reception of a proposal. However in order to minimise the risk of a "bad block" being detected after a PreparedCertificate being created, it has been decided to validate the whole block (i.e. exercise the transactions, process the block and ensure hashes etc line up with the header). There is still some (minor) risk of a failed block import, however it is substantially reduced.
