The counterparty risk for Custodial wallet and Cashu users is that the server operator might run away with the funds. Liquid users face the risk that multiple federation members might collude to steal the funds. Spark users face the risk that the service providers might collude with the previous sender to double-spend the received funds. The counterparty risk for Ark is that if the user stays offline for too long and their VTXO expires, the service provider may be able to take control of it. The counterparty risk for Lightning channel users is that if the channel counterparty broadcasts an old state (a settlement transaction favorable to them) on-chain, and the user fails to come online and publish the latest state within the dispute period to contest it.

Perhaps only a dramatic increase in battery energy density could eliminate the need for push notifications. Because phone batteries are limited, the OS doesn’t allow the app to keep running in the background. When the user isn’t actively using their phone, we have to rely on a notification server. The notification server watches the relays for the receiving address; if it detects a new message, it sends a system-level push through iOS APNs (Apple Push Notification service) or Android FCM (Firebase Cloud Messaging). The hard part is that if users choose their own custom relays, the notification server would have to monitor an enormous number of relays. View quoted note →

Message notifications become more difficult when users are free to choose the relays.
