Somebody made an url shortener, with a Nimq mining element involved.
The general idea is that you shorten an URL via the application at:
https://shortnim.ml/The person clicking the link will be directed to a shortnim page that loads the Nimiq miner and mines a number of shares before continuing. These shares are attributed to the person that created the link. More specifically, the shares are shares in a Nimiq mining pool, resulting in NIM payouts in the end.
As creater of the shortlink, you can specify the nimiq address that receives (in the end) the NIMs mined and the url to shorten.
If you want to give it a try:
https://shortnim.ml/r#k1z2xI guess it won't be useful in practice because the time needed to mine a single share is too long for people to accept this delay. But is crafted fairly well.
If you use it for a link that people find helpful/valuable (like a link to the latest Nimiq Community update on Medium.com), it could work ok.
