YAHOO NEWS - Mar 3 - LegalFling is an app that allows users to catalog their consent with a partner. The app's tagline says: "Get explicit about sexual consent." Still in beta, it's powered by Live Contracts, a Netherlands-based startup that allows users to create instant, easy-to-understand, legally binding contracts in minutes. Relying on blockchain, a technology that encrypts data, the contracts are only accessible to the two people involved, and the claim is that they are 100% safe from hacking. Just like Tinder or Bumble, users choose to X (swipe left) or heart it (swipe right). A heart is yes and an X is no. But the reality may be more complex.
