@HoOngEe What is the current status of this PR?
Do you need someone to review it? Or something is not done yet?

HoOngEe · 2019-07-02T02:34:56Z

@majecty I need someone to review it.

majecty · 2019-07-02T02:48:09Z

@HoOngEe Please fix the conflicts.
After fixing it, @foriequal0 and I will review this PR.

What happened to the delegated CCS of the banned validator.

+                    .get(signer_idx1)


The signer may be different from the message's signer. We should get the prev term's signers.

Why give CCC as a deposit?
Any reason for this? How about give CCC directly to the informant?

Yes you are right, I misread the spec

HoOngEe · 2019-07-05T10:54:22Z

@foriequal0 I remember you mentioned about the expected compile error

^^^^^^ expected trait cstate::ActionHandler, found struct `consensus::stake::Stake`

at the line
But I could not recall the solution.

HoOngEe · 2019-07-05T10:57:32Z

I have almost done. But I would better to change the error handling policy on "Cannot get validators from the parent state" part.

HoOngEe · 2019-07-08T08:55:02Z

Now I'll change the error types which would be returned by the ActionHandler::verify method.

(Question) Do we have a chance to have the same signer with two different signer indexes?

So sharp. I'll change the code like this:
First compare signer_idx1 and signer_idx2. If they are different, invoke an error.
Then, I'll get signer public key without collecting all pubkeys in vector.

You could've accepted just &ConsensusClient. Anyway, We'll ship it now and fix it later.
