DPoS-based voting with a cap at 250,000 SP to prevent dominance by a single account (this means that all accounts with over 250 SP will be treated as if they have only 250 SP; accounts with less than 250 SP will not be affected)
Do you mean 250000 SP or 250 SP?
Thank you for bringing this up. It reverted the last time I edited the document via the Steemit frontend which currently has a minor glitch that reverts edits before they're accepted. The number is 250000 SP.
