The old scheme had some elementary flaw, which is fixed here.
The main flaw with the previous one was that it was unfair to the reward of those who were already in the pool. In other words, If you join a pool now, any unclaimed rewards belonging to others would now also be shared with you as well. New tests ensure this property.
The new design is still scalable, in fact much simpler, and maintains this property as well. The spec is being written with proofs here: https://hackmd.io/PFGn6wI5TbCmBYoEA_f2Uw
The code should be a 100% clear mirror of what the spec is defining.
All existing pools on Kusama and Westend need to be migrated to this system. Moreover, a new fie field has also been added to members, which means all members also need to be migrated.
