cycles-quartz

A Rust implementation of the cycles protocol and the Quartz app framework.

This repository contains the following components -

Apps

Quartz applications, each consisting of CosmWasm smart contracts, Gramine based sidecar enclaves and accompanying ZK proofs.

Currently implemented apps -

• MTCS - The default app which implements Multilateral Trade Credit Set-off.

Core

The Quartz core implementation including -

• Core handlers and types for Quartz
• Intel SGX remote attestation (RA) primitives
• Light client and merkle proofs for CosmWasm storage

CosmWasm packages

CosmWasm packages for the core Quartz framework and remote attestation verification.

Utils

Utilities for supporting Quartz development and -

• cw-prover - Retrieve a merkle-proof for CosmWasm state
• cycles-sync - Sync obligations and setoffs with Obligato
• mtcs-intent - CLI for keygen, encrypting/decrypting obligations/setoffs, etc.
• tm-prover - Generate light client and merkle proofs for CosmWasm storage in a format that Quartz understands
