We propose to do a major refactoring of our parachain staking pallet used for LDPoS: Rewards will not be moved into wallets of collators and delegators automatically. Instead, we migrate to a pull-based approach in which each user has to actively claim their rewards. However, the rewards will still be accounted automatically.

This idea was proposed by multiple users to reduce the number of Rewarded events. As a result, the scalability of the KILT network is increased by orders of magnitude and it enables users to have full control over the timing for their reward. The latter should make tax reporting much easier. Unclaimed rewards come with an unlimited lifetime. Thus, from a technical perspective, there is no need to worry about claiming frequently.

We added runtime API calls to query the amount of your unclaimed rewards. Claiming these is fairly simple and can be done in a simple batch call. Our Stakeboard will also display the amount and provide means of claiming them easily.

For more details, please read out blogpost on Medium. Apart from that, you can also check out the Github release for more information.
