Jack Dorsey's Cash App Integrates Bitcoin's Lightning Network

An anonymous reader quotes a report from Bitcoin Magazine: Users of Block's mobile payments platform Cash App can now make instant and free bitcoin payments through the Lightning Network, the company tweeted on Monday. The integration of Bitcoin's second-layer protocol for faster and cheaper transactions was made possible by the Lightning Development Kit, an open-source project developed by another company owned by Block, Spiral. The Lightning Development Kit (LDK) is a flexible Lightning implementation geared towards developers who want to integrate Bitcoin's Lightning Network into their applications frictionlessly. It abstracts away complexities of Lightning, enabling developers to integrate the network easier and faster into their apps. Jack Dorsey said in a fireside chat last week with Michael Saylor, the CEO of software intelligence company MicroStrategy, that having Cash App integrate Lightning through the Spiral's work was one of the proudest moments of his career. [...] Despite critics saying that Bitcoin cannot be used as a means of exchange due to its base layer's slow settlements, Lightning empowers Bitcoin to handle the smallest of payments for little to no cost. Now, all Cash App users can also leverage Lightning to send small payments instantly and for free. However, it seems that Cash App cannot yet receive Lightning transactions itself -- only send them.
