Change Description
New policy for dropping all incoming blocks while producing blocks. This prevents extra work by BPs from
abort_blockand is far simpler than attempting to determine if the incoming block is potentially relevant to the chain.Since this sets up a situation where the last block, if received late, is likely to be dropped, this PR also changes the default value for last block time offset to -200000us. BPs who have already explicitly set the
last-block-time-offset-usparameter may want to re-evaluate in light of this change.Succinctly, It is now the default policy that BPs are responsible for shipping out their last block(s) early enough such that the next BP will receive them before they start producing or risk having their work dropped.
