Roles

• Admin - add, update, remove group members (not necessary to be a member of the group)
• Members - submit proposal, vote
• Group policy account - could be an admin of a group

Decision policy types

• Threshold decision policy

// policy.json for create group policy
{
    "@type": "/cosmos.group.v1.ThresholdDecisionPolicy",
    "threshold": "1",
    "windows": {
        "voting_period": "120h",
        "min_execution_period": "0s"
    }
}

• Percentage decision policy

// policy.json for create group policy
{
    "@type": "/cosmos.group.v1.PercentageDecisionPolicy",
    "percentage": "0.5",
    "windows": {
        "voting_period": "120h",
        "min_execution_period": "0s"
    }
}

Proposal

• withdraw proposal (executed by admin or proposer)
• aborted proposal

Group msg type list

// Policy
/cosmos.group.v1.MsgCreateGroupWithPolicy
/cosmos.group.v1.MsgCreateGroupPolicy
/cosmos.group.v1.MsgUpdateGroupDecisionPolicy
/cosmos.group.v1.MsgUpdateGroupPolicyMetadata
/cosmos.group.v1.ThresholdDecisionPolicy
/cosmos.group.v1.PercentageDecisionPolicy

// Manage group
/cosmos.group.v1.MsgCreateGroup
/cosmos.group.v1.MsgUpdateGroupMembers
/cosmos.group.v1.MsgUpdateGroupAdmin
/cosmos.group.v1.MsgUpdateGroupPolicyAdmin
/cosmos.group.v1.MsgUpdateGroupMetadata
/cosmos.group.v1.MsgLeaveGroup

// Proposal and voting
/cosmos.group.v1.MsgSubmitProposal
/cosmos.group.v1.MsgWithdrawProposal
/cosmos.group.v1.MsgVote
/cosmos.group.v1.MsgExec

Note

The pattern that is recommended is to have a single master group policy for a given group, and then to create separate group policies with different decision policies and delegate the desired permissions from the master account to those "sub-accounts" using the x/authz module.
