@Jannes, that doc seems to be more of an anti-PoS doc than a proposal for a modified security scheme.

Warning people to think twice, before investing time or money in something overhyped yet unproven and even long discarded as impossible by people in the know, seems only fair. (They got sick of explaining this to people over and over again, that's why they wrote this paper.)

We can add "Proof of Luck": https://bitcointalk.org/index.php?topic=442626.0;wap2 and https://github.com/nejucomo/cryptocurrencydesign/wiki/Proof-of-Luck

@sw. Taking a quick look at those links makes me think that this is more like buying a scratch ticket than a distribution scheme for a coin.

<p>I'm looking for other types of distribution models for crypto coins that are like POW (proof of work) and POS (proof of stake). I'm assuming these are a type of distribution model for coins, or is there a better term for it? I mainly want to find other systems that have unique ways of distributing a coin. Is there a list somewhere?</p>

What other whitepapers are there for coin distribution models like POW (proof of work) and POS (proof of stake)?
