Where are laravel password salts stored?
The article that you linked seems to contain the answer.https://mnshankar.wordpress.com/2014/03/29/laravel-hash-make-explained/
The cleverness of this is that the algorithm, salt and cost are embedded into the hash and so can be easily parsed out into individual components for reconstruction/verification (Please see relevant sections of the php crypt source code at https://github.com/php/php-src/blob/master/ext/standard/crypt.c#L258). Because of this, you don’t need to store the salt/cost separately in a database table.
