Cross chain (bridge how to)

[alanpoon]

I want to perform cross chain between 2 different substrate nodes. Am I supposed to modify https://github.com/scs/substraTEE-worker/blob/master/worker/src/main.rs to pipe the extrinsic transaction from 1 node to another node?

Actually, we have a failed grant proposal for exactly this, possibly to be re-tried in a few months:
w3f/General-Grants-Program#140

If you want to move on, have a look at the proposed approach. You actually might find our next planned additions useful, (a pending grant for implementing proof of inclusion) w3f/General-Grants-Program#214
With a bit of luck, this might happen in Q1

Without this light-client functionality your bridge will trust the worker (not the enclave) which is very undesirable

With regards to w3f/General-Grants-Program#140,
Am I supposed to import the functionality of the FinalityProofImport trait into the enclave?

As we haven't done this yet, I haven't looked into the details. I guess the riot chat is the better place for advice.

I'll close this as no action seems required
