libbolt

A pure-Rust library implementation of BOLT: Blind Off-chain Lightweight Transactions.

BOLT is a system for conducting privacy-preserving off-chain payments between pairs of individual parties. BOLT is designed to provide a Layer 2 payment protocol for privacy-preserving cryptocurrencies such as Zcash, by allowing individuals to establish and use payment channels for instantaneous payments that do not require an on-chain transaction.

WARNING

The libbolt library relies on experimental libraries and dependencies at the moment. It should not be deployed in production software yet and has not undergone a security review.

[dependencies]
libbolt = "0.1.0"

Then add an extern declaration at the root of your crate as follows:

extern crate libbolt;

API

The libbolt library provides APIs for three types of privacy-preserving payment channels:

• unidirectional payment channels (not done)
• bidirectional payment channels (done)
• third-party payments (not done)
