Bitcoin’s newest mobile privacy feature can make your incoming money completely invisible

Silent Payments promise a reusable Bitcoin address without exposing an obvious chain of payments to that address. A sender uses the recipient's public information to derive a fresh Taproot destination, and the recipient's wallet later scans eligible transactions to find the output that belongs to it.That receiving scan has been the difficult part for phones. A September measurement project reports that BlindBit Oracle v2's complete scanning feed would require about 8 MB per day near the upper end of its dataset. The number suggests mobile bandwidth may be manageable. It also highlights a separate risk: a light wallet depends on an indexer to deliver complete scanning data, and an omitted entry can leave a real payment undiscovered.The emerging tradeoff is therefore less about raw download size than about what a wallet can verify. The data can fit through a phone connection. The wallet still needs a reliable way to know that every relevant piece arrived.What the measurements establishThe project processed every Bitcoin block from height 709,656 through 965,089, an inclusive span of 255,434 blocks from shortly after Taproot activation to September 2026. Its per-block CSV contains the...
