Conversation
Proposes a protocol extension allowing SPV/lightweight wallet clients to submit transactions into the Dandelion++ stem phase via a new handshake negotiation (dandelionsubmit/dandelionack). Includes rate limiting to prevent stempool abuse and maintains full backward compatibility with existing nodes and clients. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Proposes a protocol extension allowing SPV/lightweight wallet clients to submit transactions into the Dandelion++ stem phase, extending DigiByte's existing privacy infrastructure to mobile wallet users.

Motivation
DigiByte ships Dandelion++ (enabled by default since v8.22), but the privacy benefit currently only reaches full-node operators. SPV/mobile wallet users — an increasing majority — get zero transaction-origin privacy from the protocol. This extension would make DigiByte the first UTXO chain to offer stem-phase privacy to lightweight clients.
