Currently both the `transfer()` and `transferFrom()` functions check that the `msg.sender` is not blacklisted (as shown in the example below). ```solidity require(tokenBlacklist[msg.sender] == false); ``` However, it might also be beneficial to ensure that the `_to` address, or the receiver, of the tokens is also not on the blacklist to prevent tokens from being locked up within the addresses of blacklisted addresses that can no longer send out tokens.

The **require** statement can be used to check for conditions and throw an exception if the condition is not met. It is better to provide a string message containing details about the error that will be passed back to the caller.

Solidity frequently releases new compiler versions. Using an old version prevents access to new Solidity security features. Also, recent versions may be too early to be trusted. solc-0.4.24 is not recommended for deployment ```solidity=1 pragma solidity ^0.4.24; ```
