Introducing zkstats.io - at Standard Crypto we've built a dashboard to track the volume and costs of ZK proofs submitted to Ethereum Mainnet. We hope this tool is helpful for monitoring the health and growth of individual projects and the ecosystem at-large.

Is "ZH proofs submitted to Ethereum Mainnet" a good indicator of the overall "health/activity" of the ZK ecosystem, or might some activity not be represented because some proofs aren't submitted to mainnet? Sorry if that's a dumb question, but I don't fully understand the full pipeline/workflow for ZKP
