Boomerang is a bitcoin cold storage protocol that provides duress protection via a non-deterministic withdrawal mechanism, interweaved with duress checks. This is the proof-of-concept (POC) implementation of boomerang protocol. All entities are written in rust. For more info on the design please refer to boomerang design repo.

• Setup and withdrawal steps
• Run
• Architecture
• Roadmap

All steps are laid out clearly in setup.rs and withdrawal.rs files, exactly following the design message diagrams of setup, initiator withdrawal and non-initiator withdrawal design files.

We have tested and ran this code on linux and mac.

cargo run --bin poc

Decisions on the architecture of the POC, are documented in the Architecture.md file.

• Writing the POC in rust.
• Dynamic simulation of the protocol to optimize parameters, given delays and non-linearity.
• Implementing the java card applet (Boomlet).
• Observing and deciding if java card can handle the expectations.
• Implementing the ST software and hardware.
• Implementing ancillaries.
• Implementing network layer.
• Implementing proper error handling and fallback scenarios.
• Adding networking and CLI to the code.
• Adding GUI.
