fork this repo and start your work based on the ab/node-template-sink branch

the demo setup is described here. should allow to fully reproduce the sub0 demo: https://github.com/encointer/personhood-oracle/blob/ab/node-template-sink/README.md

make the Oracle write to frequency

refactor this RPC call to send an extrinsic to fequency instead of node_template

definition of rpc method:

https://github.com/encointer/personhood-oracle/blob/6a518bcfcf4d6989868b017dab5122888bfb3225/enclave-runtime/src/rpc/worker_api_direct.rs#L239

here we verify encointer reputation:

https://github.com/encointer/personhood-oracle/blob/6a518bcfcf4d6989868b017dab5122888bfb3225/enclave-runtime/src/rpc/worker_api_direct.rs#L520-L527

then we compose an extrinsic (here comes your extrinsic). We hard-code metadata here. good enough for demo, but we have upstream issues in the backlog to defive this from metadata more easily

CLI client

The easiest start will be to use our cli client for the demo:

refactor this according to your needs:

browser dapp

If you insist on a js dapp for the demo, you may find inspiration here: A while back, Encointer has integrated Integritee rpc's: https://github.com/encointer/encointer-js/tree/master/packages/worker-api

noteworthy technical debt

with relevance to the frequency use case

longterm FYI:
