You have probably already seen them on bridges all over the world, padlocks which significant others lock to a bridge to seal their love. The history of these love locks dates back over 100 years to Serbia but has quickly spread worldwide. These little locks are a beautiful romantic gesture and the perfect gift for your anniversary, wedding or valentines day.
But they also have their caveats. There was the story of the famous Pont des Arts bridge in Paris which collapsed under the weight of 45 tons of love locks and some municipal authorities treat them as vandalism and remove them.
So the basic idea of this little website is to put that romantic love lock gesture on the blockchain which makes it really immutable, undestroyable and forever. No waste, no pollution of the environment and no way to remove it. A bit nerdy but certainly a very special gift for your loved ones.
hint!!!!: this is actually a serious commitment! you life on the blockchain forever! no divorce possible :D
