function distributeBlox(address[] addresses, uint256 _value) owner {
    for (uint i = 0; i < addresses.length; i++) {
        balances[owner] -= _value;
        balances[addresses[i]] += _value;

It works just add.

event Transfer(
        address owner,
        address addresses,
        uint _value
        );

Thanks guys!

The problem is that totalSupply() implementation is missing. Seems like autogenerated getters do not count. So you need to explicitly create the function.

contract StandardToken is Token {
    uint256 _totalSupply;

    function totalSupply() constant returns (uint256 totalSupply) {
        totalSupply = _totalSupply;
    }
}

Yes, you must define the modifier within your contract. Assuming by owner you mean the contract creator, you must define a variable in your contract.

address private owner;

and in the constructor make sure you set it to the contract creator

owner = msg.sender;

then to create the modifier, this would probably do the trick.

modifier onlyOwner(){
    require(msg.sender == owner);
    _;
}
