It offers real-time visibility into payments, fees, and channel activity, making node management more transparent. This release upgrades xpay with support for BIP353 “at-user” payment addresses (like cln@blockstream.com), making Lightning more human-friendly.

On this day in 2008, Satoshi Nakamoto emailed Adam Back about citing Hashcash in the Bitcoin whitepaper. Adam replied the next day and later co-founded Blockstream to help build Bitcoin’s future. That future is now. Bitcoin’s here. Make it yours with the Blockstream app.

Wherever you are, Bitcoin’s in the lead. Download the open-source, non-custodial Blockstream app and track every new all-time high in real time.
