The Zero Option Is Possible: Trustless Ethereum on a Phone, Without RPC
The EF Mandate requires a "zero option": wherever an intermediary-free path is possible, it must be built. For chain access, that path now exists. Myotis is an open-source light client for Android, iOS and desktop, as standalone app or embedded SDK: BLS sync-committee verification anchors beacon headers, state is fetched from peers over devp2p/SNAP and checked with Merkle-Patricia proofs. No RPC provider in the loop.
The talk covers the following, with a live demo if connectivity allows:
- Living inside the weak-subjectivity window on a phone that sleeps
- Which trust assumptions remain (checkpoint, bootnodes, peer availability) and how to shrink them
- What doesn't work yet: log queries (log index bundling) and historical data access
- Truly permissionless: apps built on Myotis need no API keys, accounts or rate-limit deals
Users leave knowing how to install Myotis and point their wallet at it instead of their usual RPC provider; developers, how to drop RPC from their app.
