Whitelists and Blacklists

[LinuxIsCool]

The owner should be able to choose a consensus mechanism on initialization

1. Owner has full authority
2. Any Payer has authority
3. Unanimous Payers have authority
4. Percentage of Payers have authority
5. Fund-weighted authority

Consider re-using the whitelist to approve payers. Consider the 'Permission less' whitelist mechanism.

These are my initial thoughts for designing the voting mechanism for the whitelisting operation.

class ProposalInverter:
    voting_mechanism = VotingMechanism()
    
    def add_broker(self, broker):
        if broker in self.whitelist:
            self.brokers.add(broker)
        else:
            self.waitlist.add(broker)

    def vote(self, voter, broker, vote):
        voting_mechanism.vote(self, voter, broker, vote)
        if broker in voting_mechanism.whitelist:
            self.brokers.add(broker)

The VotingMechanism class is meant to be modular to accommodate the different possible methods of voting.

class VotingMechanism:
    whitelist = set()
    waitlist = set()
    prior_votes = dict()

    @abc.abstractmethod
    def vote(self, proposal, voter, broker, vote):
        pass

    def add_broker(self, broker):
        if broker in self.whitelist:
            pass
        elif broker not in self.waitlist:
            self.waitlist.add(broker)

All the specific voting mechanism will build on this base class.

class WeightedVotingMechanism(VotingMechanism):
    def vote(self, proposal, voter, broker, vote: bool):
        self.add_broker(proposal, voter, broker, vote)
        self.prior_votes[broker][voter] = vote

        if sum([proposal.payers[payer] * vote for payer, vote in self.prior_votes[broker].items()]) > proposal.funds / 2:
            self.whitelist.add(broker)
            del self.waitlist[broker]

Notes from today's PrimeDAO workshop:

• The call to super() in each mechanism should be after the if statement
• Rename Consensus to Unanimous, since consensus means a general agreement
• Check that the minimum number of brokers is in minimum conditions
• When whitelisted, check that the broker doesn't hit the max
• Applying to waitlist and applying to whitelist are two separate operations
• Add permissionless whitelist mechanism
