Bitcoin: When Lightning Strikes
summary
Lightning runs as a layer‑2 payments rail that moves value off‑chain for instant, cheap settlement; Cash App already ships Lightning to 44 million monthly active users and uses the Lightning Developer Kit and BDK to integrate. Routing nodes earn tiny fees in a permissionless market, and services like Loop and Pool liquidity services rebalance channels. Custodial vs noncustodial use changes privacy and tax exposure; Blockstream trials a hosted-but-user‑keyed service called Greenlight and work on TARO/taproot asset overlay to bring stablecoins to Lightning.
