Project Abstract

Our aim is to research whether implementing a Java-based Host is feasible. Significant components that will be explored and designed on a high level are:

  • Runtime Execution Environment (using wasmer-java)
  • P2P Communication
  • Storage (persistence) module
  • RPC API

Our most significant efforts will be on the Host <> Runtime communication (execution environment) as it is the area that has the most risks.

Grant level

  • Level 1: Up to $10,000, 2 approvals
  • Level 2: Up to $30,000, 3 approvals
  • Level 3: Unlimited, 5 approvals (for >$100k: Web3 Foundation Council approval)

Application Checklist

  • The application template has been copied and aptly renamed (project_name.md).
  • I have read the application guidelines.
  • A BTC, Ethereum (USDC/DAI) or Polkadot/Kusama (aUSD/USDT) address for the payment of the milestones is provided in the application.
  • The software delivered for this grant will be released under an open-source license specified in the application.
  • The initial PR contains only one commit (squash and force-push if needed).
  • The grant will only be announced once the first milestone has been accepted (see the announcement guidelines).
  • I prefer the discussion of this application in a private Element/Matrix channel. My username is: @_______:matrix.org (change the home server if you use a different one)

Thanks a lot for the application. This looks really good and makes sense to me. I shared it internally and will mark it already as ready for review. I'm also personally happy to go ahead with it.

Thank your application. It looks great and we are excited to get this going.

The only thing that I would request is that you also include some research into schnorrkel and scale in the proposal, so that we cover all the basic building blocks. (For example it would be worth while to see how much of polkaj would be usable to build a host.)

Lastly, I wanted to mention that after taking a quick look at the official JVM libp2p implementation, it seems like you will most likely have to implement yamux and kademlia to get going, which is something we should start discussing with Protocol Labs.

Thank you for the well-presented application. I had a few clarifications regarding the deliverables:

1.a PoC: What is the scope of the PoC? Will it run wasm blobs with the same complexity and API used by current runtime? Would it be tested on synthesised examples or real-world runtime pallets for performance?
2. Research: Note that the jvm-libp2p implementation seems to be WIP https://github.com/libp2p/jvm-libp2p and missing several components like p2p discovery.
4. Research: Could you please bifurcate the design doc of this module separately for Full Node and Light Client.

I'm still happy to go ahead with it. Btw. I already reached out to protocol labs.

LGTM. Only thing i would emphasise is that performance should be a key dimension to be tested on for the 1a deliverable, since a performant Runtime Environment is a critical requirement (specially for full nodes).
