According to CoinMeta, payment company Block announced on September 24 that it would integrate Bitcoin Lightning Network into its x402 payment standards. The x402 protocol allows for verification and data unlocking through Lightning Network invoices and payment pre-images after the server returns a HTTP 402 payment request. spiral official Steve Lee stated that this integration is aimed at instant, low-cost small-value payment scenarios. Block has not yet disclosed a timeline for integrating these standards with Cash App, Square, or Bitkey; related implementations still need to pass real-node testing.
