When does offline receiving come into play?

Blitz Wallet 5mo ago

If you receive a payment while the app is closed, Spark still works reliably without relying on push notifications to receive that payment like other self-custodial wallets. The trade-off is that it introduces a trust assumption in Spark.

Interesting. What other differences are there between this method and what ZEUS has done? It sounds like an advantage might be that there’s no 24-hour window to redeem payment.

ZEUS uses hodl invoices, which are A) somewhat unreliable and B) harmful to the Lightning Network, as they lock up channel liquidity.

Spark takes a different approach. It doesn’t use hodl invoices. Instead, when someone sends you a Lightning payment, it’s auto-swapped into Spark. Then, when you come back online, you co-sign with the Spark operator to regain full control of your funds via a combined key.

The main difference is in the trust model: ZEUS is fully non-custodial and trustless, while Spark introduces a 1-of-N trust assumption—only one honest Spark operator is needed to keep your funds secure.

Good to know. Thanks. 🤙

Kudos you guys! Y'all are doing a great job with Blitz. I'm taking notes for Coinos.
