Talk:Proof-of-work system
From Wikipedia, the free encyclopedia
- the "Reusable POW" section belongs to a page of its own, thus should be moved.
- this "POW" page should just focus on POW systems.
- it should point to applications/extentions such as "RPOW".
- the distinction (if any) between system/protocol/function should be clearer.

Does direct human interaction (like inserting "humans_remove_me" in an email address) qualify as a POW algorythm? If so, it would seem to be a challenge-response variant, and might be worth mentioning as a real-world example. Concepts such as these can always do with the addition of simple examples.

- For schemes that require human interaction see CAPTCHA. Both proof-of-work system and CAPTCHAs are not symmetric in the sense that generating challenges is much easier than solving them. Therefore, inserting instructions in e-mail addresses does not seem to qualify for either of the two concepts. 85.0.104.237 (talk) 09:32, 2 February 2008 (UTC)
