  • 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. Msanford (talk) 04:17, 2 February 2008 (UTC)

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. (talk) 09:32, 2 February 2008 (UTC)

The link at the end of the page is a link to the domain parking. Is that as intended? (talk) 06:24, 28 July 2010 (UTC)

Is it really called "to mint" instead of "to mine". Could someone link that term to some other wikipage, if thats in fact the correct term? (talk) 19:58, 30 May 2011 (UTC)


The entire Reusable POW section looks like original research/self promotion. SuzieDerkins, as you contributed to it most, do you have a particular reason for including so much on one particular implementation? MarkSteward (talk) 23:08, 2 June 2011 (UTC)

SuzieDerkins: I did not write anything in the RPOW section. I contributed the first part. I agree that this second part lacks generality, and is self-centered. — Preceding unsigned comment added by SuzieDerkins (talkcontribs) 05:59, 5 September 2011 (UTC)

In the following: " is impractical to hold onto a POW or RPOW token for years as a form of savings. Still, these tokens are quite useful and stable when used as a form of exchange." I question the value or the neutrality of the last sentence. Stable as compared to what, useful as compared to what? It sounds self promotional. Frugen (talk) 00:16, 4 June 2011 (UTC)

I agree with you Frugen this difinatly sounds point of view. its sounds like opinional thing as in based on someones opinions. it needs a citetation from some kind of expert in e-commerce in order to be a valid argument or atleast so that a knowlegable person is really trying to give advice or something. it should be worder like this "acorder to (name of reliable source person) says " is impractical to hold onto a POW or RPOW token for years as a form of savings. Still, these tokens are quite useful and stable when used as a form of exchange." at least in this useage its more credible. as of right now im not a supporter of purely digital money systems becasue the US government is agaist it becasue international criminals use it to steal (talk) 12:49, 18 July 2012 (UTC)

Reusable proof-of-work[edit]

"It is in fact the only form of digital token money invulnerable to inflation caused by greedy or untrustworthy mints issuing more tokens than they said they would issue." What's that all about? I came to this page to read up on Internet security and suddenly it feels like I'm reading a blog written by a bitcoin militant. Presuming it to be true, a neutral statement would say "It is the only form of..." , and would drop the word 'greedy' as it is a value judgement and is anyway covered by 'untrustworthy', which is itself not a neutral term, so 'unreliable' would be more objective. — Preceding unsigned comment added by Vynbos (talkcontribs) 15:45, 21 November 2011 (UTC)

There were issues of WP:NPOV, WP:RS and WP:UNDUE here, to varying degrees. I've trimmed the section as much as I can, stripping out the editorializing. I'm not a crypto hacker, so I can't speak to the technical accuracy. Yakushima (talk) 11:01, 28 April 2012 (UTC)
