RC pools will be a big thing going forward,
but at the same time, so will second-layer / off-chain scaling solutions.

There are a lot of projects here that put information on the blockchain for no reason.

Take the games Drugwars and NextColony for example. Neither of these projects needs to be putting database information on the blockchain. If RCs were actually worth something they'd move off chain in a heartbeat.

Imagine playing a game with someone on Steem but never passing the information through Steem. Imagine signing transactions with your posting key but instead of sending it to the blockchain you send it directly to your opponent to avoid RC costs.

If anyone tries to cheat you can prove cheating occurred by bringing it back to the main chain. This is the same concept as Plasma (ETH) and the Lightning Network. Because there is a penalty associated with cheating and it can be proven that you cheated... no one will do it.

This is what makes Steem the best prototyping platform. We have a built in community willing to try out new dapps. These dapps piggyback off the main chain and the full nodes. if the dapp becomes popular enough they can move off chain with the bulk of transactions and only use the blockchain for value transfer and security/logins.
