A chat app where you subscribe to publishers and participate in their chats. You can tip them with BitCoin by sending micropayments of Satoshis. One Satoshi is 1/100,000,000th of a BitCoin. If BitCoin were $55,0000, then 1 Satoshi is worth $0.00055 (a fraction of a penny). It's open source. You can run a full lightning node or have them host a lightning node for you. Lightning nodes are level 2 payment features of the BitCoin network, where you have a channel open with someone else with some BitCoin pre-deposited inside of it. From there, you & the other party can send and receive BitCoin between the two of you instantly with little or zero fees and it's 100% private. These Lightning Network transactions are OFF-CHAIN.
