{"@context":"https://schema.org","@type":"TechArticle","headline":"Real-time notifications for Zcash","description":"Lantern Zero is an open protocol that gives Zcash wallets scheduled wake-ups and, when you opt in, shielded payment alerts within seconds. The server sends a keyless ping every 30 minutes by default, holds no viewing keys, and never sees your IP address because requests use Oblivious HTTP through an independent relay. Scanning mode lends an incoming viewing key in memory so the server can watch the chain and mempool and push an encrypted alert. The protocol and server are open source under MIT or Apache-2.0; the hosted service is pre-alpha and no wallet ships support yet.","url":"https://lanternzero.com/zcash-notifications","dateModified":"2026-11-01","author":{"@type":"Organization","name":"Principle Zero Labs","url":"https://lanternzero.com"}}
