You're perhaps thinking of https://nano.org https://nano.org ? A brief description of it's Open Representative Voting (ORV) consensus mechanism: "A consensus mechanism unique to Nano which involves accounts delegating their balance as voting weight to Representatives. The Representatives vote themselves on the validity of transactions published to the network using the voting weight delegated to them. These votes are shared with their directly connected peers and they also rebroadcast votes seen from Principal Representatives. Votes are tallied and once quorum is reached on a published block, it is considered confirmed by the network."
