EigenCC Privacy Operators

It's easy to develop new privacy operators via EigenCC Framework.

Steps

1. Define the service. A service could be a collection of methods handling the private object on Blockchain. A built-on Echo service here is provided:

pub struct EchoWorker {
    worker_id: u32,
    func_name: String,
    input: Option<EchoWorkerInput>,
}

• worker_id must be unique globally, an integer beginning at 0, increased by service.
• func_name is the service name, and also the second argument of eigen_create_task
• input : arguments of service;

2. Define the service input An input is a structure containing the arguments of each service call. the EchoWorkerInput recepts a String value. Usually, we need preprocessing for the input before being fed into service execution.

3. Define service side logic All the handling logic should be defined in the execute function:

fn execute(&mut self, _context: WorkerContext) -> Result<String>

4. Register the service

Expose the service to EigenCC framework by adding

mod service_source_file_name;
pub use service_source_file_name::service_struct_name;

to mod.rs

1. Define client side logic

Call the service by c or rust SDK.
