For Microsoft people in here, I demoed Ark in a previous call. Lightning is used for payments but lightning has 2 huge flaws: It's mostly custodial or it's complicated to self-custody. Second's implementation of Ark solves this. If you're interested in the future of payments, give Matthew Vuk a follow.
