Any timelines on the getting the WASM execution engine into Cadence? Ref - https://forum.flow.com/t/idea-wasm-execution-engine-in-cadence/5164/16

Idea: WASM Execution Engine in Cadence
Love the Idea! This means that more complex computational logic can be implemented through Wasm, but data storage still exists in the form of Resources in Cadence. The first question that comes to mind is the accessibility of Resource data in Wasm, as this involves capabilities and access control in Cadence. If the use of wasm is limited to o...

If this is a technical question that others may benefit from, considering also asking it on Stackoverflow: https://stackoverflow.com/questions/ask?tags=onflow-cadenceContext is I’m ideating through building content-based addressing and came across an IPLD rust module. Wondering if it would be feasible to create a mechanism to derive a content-based address using this or a similar library compiled to WASM in the planned execution engine

There’s currently no concrete plan to add this. We might be able to prioritize it once Cadence 1.0 is out
I worked on a PoC a couple months ago: https://github.com/onflow/cadence/pull/2760. The remaining work is being tracked in https://github.com/onflow/cadence/issues/2853

We’ll need to finalize the API proposal and figure out things like metering, then open a FLIP, similar to the ongoing EVM work
Maybe this could also be worked on earlier through a grant
@Giovanni S | Flow do you have a link to the library? If it’s not too much trouble code and it’s not computation heavy, maybe the code can also be ported to Cadence

Nothing planned atm, just looking for rabbit holes. It’d be interesting to have a tool for deriving content-based addresses deterministically. Motivating use case was support for IPFS uri derivation and publish to commitment relayer - so derive the uri, commit to erc721 on bridging, then publish an event with the data that needs to be published with certainty that the uri will be what was committed. I’m wondering if there would be a way to stand up a gateway that resolves URI requests in a similar interface to an IPFS gateway

Oh interesting, thanks for pointing out a reference!
