A prototype of Cybros protocol implementation

This is a quick and dirty implementation that shows few use cases:

Simple echo (return the message which you input)
Echo (similar with the simple echo, but add complex features for example E2E encryption support)
NFT factory (aka Imaginator)

Please don't bother the code quality, lacking doc, and hard to use, this prototype spend me only a night to build and use for evaluate interactive with Cybros chain.

I plan to make a well design and rewrite it totally soon, I prefer the architecture would look like Faktory.

For now, You also need to know Polkadot.js.

Preparation

Install latest Deno first.
Caching dependencies
- deno cache --reload ./main.ts
- cd ./examples/echo && deno cache --reload ./main.ts
- cd ./examples/imaginator && deno cache --reload ./main.ts
- Note: If you meet error: The source code is invalid, as it does not match the expected hash in the lock file., just delete deno.lock then retry

For the NFT factory:

Deploy stable-diffusion-webui separately with --api argument.
Prepare an Akord account, new user has 250MB free space.
cp ./examples/imaginator/.env.defaults ./examples/imaginator/.env then edit it to use correct settings.

How to

Run the worker

Here's an example:

EXECUTOR_PATH="./examples/simple_echo/" ./run.sh --owner-phrase "//Alice" --subscribe-pool 4 --impl 4 --rpcUrl wss://node-rpc.cybros.network

EXECUTOR_PATH="./examples/simple_echo/" run the simple echo demo
--owner-phrase "//Alice" optional, if given the worker's owner, it will do register the worker and charge when funding are insufficient automatically
--subscribe-pool 4 listen the pool 4, the pool owner must add the worker to the pool on-chain (by offchainComputing.authorize_worker extrinsic call), or no task can assign to the worker
--impl 4 mock the impl id is 4, this is for demo only
--rpcUrl wss://node-rpc.cybros.network connect to the dev chain RPC endpoint
- Note: The dev chain is not persist

After started the app, you shall see for example Worker address: 5CmLkeupoN7tSthSD6hFj9wHYc9RyMRAWb38uo5BD6LEViGw this is the worker's address that use for on-chain operations, such as register the worker, add the worker to a pool

On-chain configuration

TODO

Create task

If everything configure well, the worker will listen to the pool and handle new tasks.

The demo limitations

By design these are allowed, but the dirty code couldn't support

A worker could run multiple tasks in parallel
A worker could subscribe multiple pools
