Light Clients & Verification

The original can be found at Zenon Developer Commons .

Research into trustless verification models for resource-constrained environments.

Overview

Zenon’s dual-ledger architecture enables lightweight verification without global state. Light clients can verify chain progress and account-chain updates using only:

Momentum headers
Compact state proofs
Local account-chain data

This aligns naturally with SPV-style verification, making browser native and mobile clients viable as first class network participants.

Key Concepts

Header-Only Verification — Light nodes verify chain progress by validating Momentum headers (Pillar signatures, difficulty, weight) without downloading full blocks or global state.

State Proof Bundles — Compact verification primitives that prove account-chain transitions without Merkle proofs or global state access.

Browser as Peer — Modern browsers can perform cryptographic verification using WASM and P2P transports, enabling trustless participation without RPC gateways.
