ALGOBLK [Algoblocks] Token

Algoblocks._toRole(uint256) (contracts/Algoblocks.sol#165-191) contains a tautology or contradiction:
- require(bool,string)(roleId >= 0,Role Id too small) (contracts/Algoblocks.sol#166)
Fix the incorrect comparison by changing the value type or the comparison.

Variable Algoblocks.TOTAL_SUPPLY (contracts/Algoblocks.sol#42) is too similar to ERC20._totalSupply (@openzeppelin/contracts/token/ERC20/ERC20.sol#40)

Algoblocks._amountLocked(address) (contracts/Algoblocks.sol#220-248) performs a multiplication on the result of a division:
-monthsPassed = (block.timestamp - cliff) / (2635200) (contracts/Algoblocks.sol#239)
-amountLocked -= (amountLocked / _vestingPlan[role].vestingMonths) * monthsPassed (contracts/Algoblocks.sol#241)
Consider ordering multiplication before division.

Algoblocks.transferWithVesting(address,uint256,uint256) (contracts/Algoblocks.sol#125-140) uses timestamp for comparisons
Dangerous comparisons:
- finalReleaseDate > _fullReleaseTimestamp (contracts/Algoblocks.sol#136)
Algoblocks._beforeTokenTransfer(address,address,uint256) (contracts/Algoblocks.sol#142-163) uses timestamp for comparisons
Dangerous comparisons:
- to != _owner && block.timestamp < _fullReleaseTimestamp (contracts/Algoblocks.sol#149)
- require(bool,string)(amount <= availableFunds,Tokens are locked accordingly to your vesting plan.) (contracts/Algoblocks.sol#158)
Algoblocks.returnFrom(address) (contracts/Algoblocks.sol#203-218) uses timestamp for comparisons
Dangerous comparisons:
- lockedAmount > 0 (contracts/Algoblocks.sol#210)
Algoblocks._amountLocked(address) (contracts/Algoblocks.sol#220-248) uses timestamp for comparisons
Dangerous comparisons:
- block.timestamp > cliff (contracts/Algoblocks.sol#236)
- monthsPassed < _vestingPlan[role].vestingMonths (contracts/Algoblocks.sol#240)
Avoid relying on block.timestamp.

Algoblocks.constructor(address).ownerWallet (contracts/Algoblocks.sol#69) lacks a zero-check on :
- _owner = ownerWallet (contracts/Algoblocks.sol#83)
Check that the address is not zero.
