Editing Validation Pool roll up (section)

== Background ==
On-chain voting is inefficient and prohibitively expensive. However, voting is necessary for [[governance|decentralized governance]]. To maintain robust decentralization, every member of the DAO should be permitted equal opportunity to participate in policing by voting with their [[Reputation|REP tokens]]. 

But each time a member votes with a REP token becomes a separate transaction. Also, properly participating members should have their REP holdings augmented with newly minted tokens (to solve the "nothing at stake problem"), which necessitates yet another transaction. 

Instead of doing all of these operations separately and on chain, it is more efficient to handle the operations off chain, then roll up the result in a single transaction in a single block. Even better, efficiency is improved if we bundle together a sequence of several separate instantiations of Validation Pools.  

Fortunately, DGF is designed for the express purpose of governing off-chain work.
