Disney

All `DIS` tokens are sent to the contract deployer when deploying the contract. This is a potential centralization risk as the deployer can distribute `DIS` tokens without the consensus of the community.

Performing integer division before multiplication truncates the low bits, losing the precision of calculation.

```solidity=1515
                denominator := div(denominator, twos)
```

```solidity=1530
            uint256 inverse = (3 * denominator) ^ 2;
```

```solidity=1518
                prod0 := div(prod0, twos)
```

```solidity=1545
            result = prod0 * inverse;
```

ERC20VotesUpgradeable is modified from openzeppelin dependency token/ERC20/extensions/ERC20Votes.sol, which is a non-upgradable contract. Modifications on openzeppelin dependency may lead to unprecedented results.
