The initial use case will be stablecoins on lightning - and use them with RGB-powered Lightning DEX named Kaleidoswap.
Other cases:
  • NFTs not polluting blockchain anyhow
  • csApps (client-side dapps not requiring internet connectivity, servers and DNS)
  • DeFi in Bitcoin (would take time to develop)
  • much more scalable and private DAOs than possible today with Ethereum
