-Duniter is a _cryptocurrency software_, which means it is a **software** providing the ability to **create currencies**. Duniter is different from other cryptocurrency softwares you may know (Bitcoin, Litecoin, Peercoin, ...) for 2 main reasons : its **currency code** includes the concepts of a [Universal Dividend](https://en.wikipedia.org/wiki/Social_credit) and [Web of Trust](https://en.wikipedia.org/wiki/Web_of_trust); but also its **Blockchain code**, which is far more energy efficient, getting rid of the massive waste of energy introduced by Bitcoin.

 ### Money is co-produced by all the community members
 
-This is the main feature: money is _equally_ co-produced by the members of the community (a.k.a. Web of Trust (WoT)). Such an equality is ensured in both space and time so that newcomers won't be excluded from the money production process [as is so with Bitcoin](http://magazine.ouishare.net/2013/05/bitcoin-human-based-digital-currency/), therefore **it isn't necessary to create yet another "Bitcoin" to have your part of the money**. This co-production implies that members be identified in the software, and thus is a mechanism to prevent people being able to create fake accounts and produce more money than others.

 ### No more CPU race: an energy efficient Blockchain
 
-Classical blockchains uses CPU power for addressing security issues. Even if it works (at least, it seems to), this is a very energy-expensive process. Duniter believes it is possible to have a similar but _more efficient_ _process_, which is not the little brother Proof-of-Stake (the power by the richest). Duniter benefits from a particular resource to reach this goal: **its identified community: its members**. Here is how Duniter Blockchain is built: each block is computed exclusively by members. Which means neither super Google nor any superpower would be able to control the chain. Moreover, Duniter adds a rotation rule, meaning **a member cannot control the blockchain alone**. A group of users could, but this would imply that their computing power be higher than the rest of the members of the network. This is where Web of Trust comes into play: each member is recognized (its identity is trusted - not its actions) if he fits the WoT rules:
