Layer 1 is often not enough to get the most out of your blockchain. And for this reason even Ethereum started it's layer 2 chain protocol. And they have been very successful at it. In fact their layer 2 chains do much more than their layer 1 work. So that expansion has been good over the years for the blockchain. Zksync blockchain has been getting into creating a hyperchain through their Zkstack. It's a build stack that they have been developing just like how OP chain has it's build stack. It allows you to create Hyperchain. Hyperchains are your layer 2 which allow you to do whatever you want for free.

What can you do with the Hyperchain? It allows you number of activities on the Hyperchain. So here are few that you can do officially. Like run a Hyperchain on your own if you have the resources. You can also run the stack sequencer and this way you would be the 2nd most popular action you can take. Prover is another component where you can run your own cryptography on the chain. So these are the top feature actions that you can take.
Next to the list would be running your own node but that would require some level of learning. For the developers and the node operators if they can afford and they can get compensated then it is worth the effort. But overall I would say building on their chain is definitely worth it for long run. In such case I'd say that zkSync is definitely worth giving a try.

Another thing to watch out is the zkStack is being used by many partner chains on the layer 2. Zksync has partnered with the AI data warehouse that would make it easier for the chain to work with the AI integration. This company is known as the space and time DB. They are building on the chain so that would be another benefit for the zkSync and in turn zkStack getting more adoption.
