Increase the cost of registering as a candidate

[erikzhang]

The idea is from #2203 (comment)

We should increase the cost of registering as a candidate to prevent attacks.

Question: What is the appropriate price for RegisterCandidate?

Hi Erik, I have a few questions:

• If they lose the election, their money is gone, right?
• Is the APY is GAS based?
• What happens to the tokens if they are not elected? Is it burned?
• Is the registration permanent? Once registered, I can always get votes and never be elected, or is there a limit for a candidate to get the votes?

My only concern is that it may be too risky for 'regular people' to participate. I mean, if there is a chance to lose $10.000, I would probably not have the courage to register as a candidate. But if that means that I will be a candidate 'forever', then it may be a good thing to increase the price.

Question: What is the appropriate price for RegisterCandidate?

I suggest that we do something based on the available supply, like 0.0001% of the circulating GAS/NEO

Yes.

Is the APY is GAS based?

Yes.

What happens to the tokens if they are not elected? Is it burned?

Yes.

Is the registration permanent?

Currently, yes. But maybe we can add an expiration date.

Hmm, maybe adding an expiration date will add too much complexity. What happens if it expires while they are elected?

Do you want to make it 'fiat pegged' prices, like U$1.000, or are you looking for something based on NEO/GAS? The second one will need to adjustable since the prices will likely go up.

i believe NEO /GAS based should be the best option to go!

i like your idea to use available supply as index , this could work also like halving mechanism

My worry is:

I pay for be a candidate, but I am waiting for two mothns without luck, one day I am candidate, but maybe I had shutdowned my computer and leaved the crypto world, we should need an ACK before be a valid one.

[Tommo-L]

we should need an ACK before be a valid one.

We thought this before. One way is that candidate can send an ack transaction before it becomes a validator(Validator need one epoch to take effect). Another way we can take advantage of committee's epoch to switch up to 1/3 nodes at a time, while checking the block production within epoch.

What about 1000 GAS for register as a candidate? @neo-project/ngd-shanghai What do you think?

it's good for me

[i359]

It is suggested to set the parameter as 1000gas tentatively, which can be adjusted by voting in the future.

I suggest to do a formula based of circulate supply since gas supply is unlimited in few years 1000 gas could be very cheap so a fixed percentage of supply could solve the problem for ever.

[ProDog]

1000 might be too high, it may affects the level of engagement. I think we should prevent attacks, but remain attractive for many users. In Neo2's experience, many users can't easily deploy contract because it's too expensive.－O－

This proposal is for registerCandidate, not for deployment.

[Tommo-L]

It's good for me, and it'll be better, if we can set a parameter.
