Hyperstaking is Dusk attempting to make staking easy and friendly to users.
Staking can be a barrier: either operate a node, uptime, or delegate, or do it inflexibly. Dusk refers to Hyperstaking (stake abstraction) as a design in which smart contracts may manage staking pools, which allows liquid staking, as users can stake without a node.
The more serious aspect:
Dusk is approaching participation as a product issue. When more regular users are allowed to stake with ease, then decentralization and security will become stronger as time goes by. It is not only reward chasing, but infrastructure thinking.
