The essence of a method comes down to the fact that in Stellar Lumens network (also as well as in the Steemit, for example) there is a planned annual inflation in 1% of the general issue of tokens of XLM. And holders of coins of XLM can vote, having specified the address which according to them has to receive Stellar coins, geneneriruyemy in the course of inflation.

If the chosen address receives more than 0.05% of votes of all holders of coins, then it will receive every week a share from issue of new tokens.

And here organizers of XLMPool have thought up the interesting scheme - to all who vote for their pool, they automatically distribute the coins received by a pool. In fact XLMPool is a certain analog of classical pools of a joint mining, only for participation in work of this pool no computing capacities are necessary.

There is enough once in a standard desktop purse to specify pool address as the recipient the generated by a network of coins - and every week the pool will list you your share of income:

As XLMPool pool is the only thing now for whom more than 0.05% of holders of coins of network have voted, he receives all coins generated in this network. Therefore approximate income on a bullet makes 1% per annum.

Of course, it isn't a lot from the point of view of specially to buy XLM for receiving passive income. But if you already have these coins and you don't plan them to sell - be connected to a pool and begin to receive let small, but stable passive income in Stellar Lumens network.
