Idena democritizes mining: any person on the planet (who able to solve flips) can mine the coins.

But what is the economy behind the coin?

Consider the use case of Sybil-protected maketing on the blockchain
1. Assume that Idena participants voluntarily agree to consume ads published on the blockchain by an advertiser.
2. However such an advertiser has to burn coins in order to reach a certain group of users attention.
3. Burnt coins are removed from the total supply. Thus multiple advertisers competing with each others will always have a shortage of coins.
4. Due to that assumption the newly minted coins which are equaly distributed amoung the people and can be sold to advertisers.
