SPV Mode
SPV mode keeps Bob small and fast to install. It can sync wallet activity, receive HNS, send HNS, manage owned names, and browse Shakedex listings from a trusted channel.

SPV Mode vs Full Node Mode
Bob starts lightweight so normal users do not need to store the whole Handshake chain before using a wallet.
Full Node Mode
Full-node mode stores and verifies more local chain data. It is still important for advanced seller flows, deeper name-state inspection, and running infrastructure for Shakedex channels.
Marketplace Behavior
SPV wallets should be able to browse and buy Shakedex listings after the active channel is fully synced. Creating seller listings is more sensitive because Bob must create and monitor the on-chain Shakedex lock.
