Stratum v2 miners begin work on new blocks faster than Stratum v1 miners. +Stratum V2 segregates the prevhash from the rest of the predefined block data, allowing independent sends of block data prior to finding a new prevhash. The new prevhash message is sent on its own on finding a valid block; the transmission occurs much faster because the message doesn’t include the heavier data.

SV2 eliminates the blind bining incentive by making full-block propagation equally efficient to empty block propagation. #### Technical Description -Stratum v1 incentivizes pools to send empty blocks containing the new prevhash, as these messages will arrive faster than a message containing a full block. Separating these two messages in Stratum V2 lets pools send full blocks to miners before the new prevhash message. The miners' end-devices are prepared to start working on a new (full) block before the previous block has been found, and only require the next prevhash message to begin mining. Since this prevhash message is the same size (i.e. takes the same amount of time to arrive) regardless of whether or not the pool has sent an empty block or a full block, there is no longer an incentive to mine on empty blocks. +Stratum V1 incentivizes pools to send empty blocks containing the new prevhash, as these messages will arrive faster than a message containing a full block.
