We are building our solution on top of the newest zk engine. But the infrastructure around it is not built (for example, no PLONK implementation). So, we need to build some infra around it (like PLONKish constraint system for plonky3).

The existing solution EthStorage uses KZG10, which is less recursion-friendly. Also, EthStorage uses replication instead of RS codes, so our data utilization is 10 times better.
