I recently came across this idea to prevent friend request spam on social media, using the Lightning network. The idea is that the person sending you the friend request must attach a small amount of money (in the form of a special lightning payment). If the friend request is legitimate, you can accept it (and not claim the money). But if it's spam you reject the friend request but take the money instead. This is different than Hashcash in that it incurs real monetary costs to the attacker. Instead of using compute resources (for the mining algorithm), the money would actually end up in your pocket.
- Retric 7y agoA much older example is the high cost of sending text messages basically eliminates text message spam.
- oarsinsync 7y agoExcept the cost of phone calls, text messages and even postal mail is sufficiently low to result in spam across all three mediums in ever larger quantities than before
- chrismeller 7y agoAs he said, it is a much older version. As with everything the cost decreases over time to the point that it no longer outweighs benefit. Put another way, this is the unfortunate flip side of free unlimited talk and text.
