 This is why part of the Operators' DATA tokens are staked in Sponsorships (through an Operator contract that they control). Only a small portion of DATA is expected to be in the Streamr Network participants' wallets, the rest is staked or delegated into the Streamr Network.
 
-'''The point of the Streamr snapshot strategy''' is to allocate voting power not only according to DATA token holding (as in the plain erc-20-balance-of strategy), but also counting in the DATA tokens the token holders control via staking and delegation (NOTE: at first, only implemented for stakers. Counting delegated DATA may be added later).
