-The Bidders also have to use Proof 2 to show that $\displaystyle ECDL_Y\left(\left(\sum_{j=1}^{k/n}\alpha_{a,jn+a}\right) - G\right) = ECDL_G\left(\sum_{j=1}^{k/n}\beta_{a,jn+a}\right)$. \\[2.0ex]

 This is to ensure bidders have only chosen valid bids for their bid index, since
 in M+1st price auctions the amount of possible prices is multiplied by $n$ to
 prevent ties. This increases the message size by $96$ bytes.
