Who

I am SyntheticBird, Cuprate contributor.

What

Cuprate is currently in alpha version and a lot of features are planned on the roadmap up to beta phase. One of the features present on this roadmap, and that was originally presented when announcing Cuprate, is native support for Tor network. This CCS proposal intend to fulfill this milestone.

I will work for an estimated 2 months, from April to end of May, on Cuprate with the goal of implementing native Tor support into cuprated through the arti-client crate and other miscellaneous improvements. At the end of this CCS, testers will be able to:

  • Bootstrap Tor network within Cuprate or use Tor system daemon.
  • Use Tor for outbound clearnet connections.
  • Natively connect to onion monero nodes.
  • Generate an onion service for accepting inbound Tor connections.

Tasks

The planned set of tasks to complete can be found at this Github gist: https://gist.github.com/SyntheticBird45/4c554d3c1e7ae6f8d237d7dd49c2d2f0

It is subject to change but overall the required work can be separated into 3 categories:

1. Alternative network integration into P2P components.

Currently, Some P2P components have limited support for alternative network rules. This will require modifying AddressBook, Connector, HandshakeBuilder, cuprate-dandelion crate and cuprated's dandelion implementation, and others to be anonymization-network-aware. After this work, we will define a new NetworkZone called Tor to connect to onion monero nodes.

2. Implementation of Arti and Tor Daemon support

Implementing arti-client inside cuprated and cuprate-p2p{-*}. Configurations, initialization, bootstrapping and launching onion services if requested. System tor daemon will also be supported.

3. Documentation

Update Architectural book and User book

Additional work

In the event that all guaranteed items are completed before the 2 months, I will spend my remaining time assisting (Issues, PRs and Reviews) on whatever is agreed is highest priority, or working on the following items:

  • Custom Allocator support (Performance improvements for Musl based linux distributions and potentially minor improvements on other OSs)
  • SOCKS5 proxy support for p2p
  • Fjall database integration
  • Related documentation

Milestones

1. First month

26 XMR

2. Second Month and completion of main tasks

26.5 XMR

Licensing

All the works completed under this CCS will be delivered to the Cuprate/cuprate.git github repository. This work will follow the current repository licensing:

  • All work inside /binaries is licensed under AGPL-3.0-only.
  • The rest of the root and crates are licensed under MIT.

Funding

I will be working 30 hours per week during 8 weeks at 45$/hr - 205$/XMR. 30×8=240 | 240×45=10800 | 10800÷205=52.5

Total: 52.5 XMR
