I am looking for the application of ZKP protocols in Substrate.

By looking around I've found a project called ZeroChain but it seems to be deprecated and no longer maintained. Are there any Substrate projects or pallets that enables me using ZKP for protecting a user's privacy and sensitive data stored on chain?

Check out Manta Network and their Kusama counterpart Calamari Network.


I think on-chain ZKP pallet is not so easy to provide, because the zkp algorithms is a trade-off between proof size and proof generation time, both of storage and calculation time is so expensive for on-chain transaction.

So, it's a good idea to try OCW.

You can also refer to parami's ZKP feature, use OCW and IPFS to achieve feasibility.


There is a WIP PR for arkworks-rs integration: https://github.com/paritytech/substrate/pull/13031
