I disagree. Use a dictionary to brute force passwords, and 'password' has exactly 0 bit of entropy. '123456' come right after it. In the end, one transaction hash among 300k offers more security than any word you could find in the dictionary. And you should consider a year of hashes, not a single day... I'm not pretending to have invented a new ultra-secure way to authenticate, just one that's secure enough (more than words, less than random passwords) and totally anonymous. Would you prefer an email-hash combo? or a hash-password? Finally, I was expecting a more positive attitude
