CKB (nervos network) is a network of interoperable protocols. I see this as a project that will solve massive upcoming problems within the crypto space. CKB solves the blockchain trilemma problem by using a layered approach.

      CKB solves the state bloat problem where the cost of storing data is taken into account and resolved using Nervos's token economics model. Nervos also solves the interoperability problem in the crypto space. Now there is true interoperability requiring many less actions from users when interacting between blockchains. Some blockchains claim interoperability but only within the same framework. CKB does not require that.

     Nervos Network is highly flexible to the point where many things can be changed on Nervos that would require a hard fork for other blockchains. CKB will store assets and the value of Nervos increases with the value of it's stored assets. 

     In my opinion CKB is one of the best long term investments out there. Everything about it is designed to be super sustainable. Even if the Nervos architects missed something, they have designed it to be flexible enough to adapt to potential changes in the crypto space.
