 A DAO DAO voting contract that uses Cosmos SDK staking for calculating voting power.
 
 For example, if I stake 100 Juno, I have 100 Juno worth of voting power in the DAO.
+
+## Naive Approach: Mirror with historical data
+
+Just query for info...
+
+Problem: no historical info.
+
+```ignore
+        QueryMsg::VotingPowerAtHeight { address, height } => {
+            // Check if is historical data
+            let staking_history = HISTORICAL_STAKING_SNAPSHOT.may_load(address, height)
+            // If no historical data, query stargate delegation info (just ignore height as long as it's less than unbonding period)
+            match staking_history {
+                // IF historical data, we use that 
+                Some(hist) => Ok(hist),
+                // else do a stargate query, user's staking balance hasn't changed since snapshotting began
+                None => {
+                    // Stargate Query!
+                }
+            }
+        }
+        QueryMsg::TotalPowerAtHeight { height } => {
+            // TODO query total power (store as snapshot map)
+        }
+
+
+
+        // cw-hooks
+        SudoMsg::AfterDelegationModified {validator: String, delegator: String, shares: String} => {
+            // if delegator is in a pending proposals vote list, update theri vote
+            HISTORICAL_STAKING_SNAPSHOT.save(info)
+        }
+```
+
+
+# on change
+- user votes, query current VP delegated
+- cw-hooks update the previous VP change amount
+
+
+When a prop is created, we could have a hook that stores current total voting power at proposal start time.
+Use clock to fire membership changed events.
+
+## Solution with Clock
+
+- Every end of block, the `SudoMsg::ClockEndBlock` will be called by the chain (when registered).
+- execute the proposal then
+- only direct votes (no validator overrides)
+- always have quaroum? (DAO config to allow for % of total, OR instant quaroum based off of the voted accounts)
+- execute it if end
+
+
+- 2bn gas limit, assume this for the contract.
+- SudoMsg::ClockEndBlock
+    - iter all proposals currently in voting period
+    - if proposal is expired, execute it
+    - on exec, query stake from stargate for everyone who voted
+    - sum this up, then perform based off the config (quaroum, % of total who did vote, etc)
+
+
+
+# flow
+- put up a proposal, text
+- people vote on it, we ONLY save their juno address to a list / map (we do not care about VP)
+- execute closes voting period, expire (pre tally)
+- ClockEndBlock sees this, then queries ALL balances from the list, tallies it up, and executes if
