amount:What
Add support to Monero daemon for broadcasting new transactions received over RPC to privacy preserving p2p connections to conceal origin IP. This proposal will use Tor hidden services, but the implementation will be written such that additional anonymity networks (Kovri?) can be added in the future.
Hidden Service Rationale
Tor can be used today via exit nodes. The issue is the potential for MitM attacks on the data, and blacklisting of the exiting nodes (to help facilitate surrounding node attacks). The recommendation is to use hidden service nodes, like Bitcoin. Users can already force traffic to Tor exit nodes through other techniques.
Who
Lee Clagett (vtnerd) will be the sole implementer. I have experience contributing code to the Monero daemon, contributing to wallet implementions (simplewallet, mymonero), and vast protocol experience. I am also familiar with some of the literature on privacy networks (this should be obvious in the proposal section).
Why
Sending transactions can be traced to their origin by ISPs, or other institutions that connect to many peers to trace the first appearance of a transaction. An entire project, Kovri, has been funded to help mitigate this issue. There are things to implement on the Monero side to make use of an anonymity network as well which will be completed with the Tor integration.
