This repository is a TypeScript monorepo implementing the Waku v2 protocol stack for decentralized, peer-to-peer messaging. It provides a comprehensive SDK (`@waku/sdk`) for building light nodes that support relay, filter, light push, and store protocols, along with advanced features like rate-limiting nullifiers (RLN) for spam protection, structured data synchronization (SDS) for reliable ordered delivery, and message encryption (ECIES/symmetric). The architecture is modular, with separate packages for core protocol logic, peer discovery (DNS, peer exchange, local cache), Ethereum Node Records (ENR), protobuf definitions, React hooks, and a local development environment via Docker Compose. The codebase targets both Node.js and browser environments, with extensive unit and integration tests using Mocha, Karma, and Playwright. While the core protocols are mature, some packages (SDS, RLN) are experimental and show signs of rapid iteration, with skipped tests and generated code that may drift from upstream specifications.
This is a monorepo for the Ember.js-based encrypted chat application 'emberclear', which provides end-to-end encrypted messaging with no server-side message storage. The architecture is modular, consisting of multiple Ember addons (crypto, networking, local-account, UI, test-helpers, tracked-local-storage) and a separate card game app (pinochle) that reuses the same networking and crypto infrastructure. The chat app uses public-key cryptography (tweetnacl, libsodium) via web workers, relays messages through Phoenix WebSocket relays, and persists data locally via IndexedDB and localStorage. It includes features like QR code identity sharing, channel voting with cryptographic chains, and a state-machine-driven setup wizard. The codebase is well-tested with QUnit, acceptance tests, and smoke tests, but shows signs of technical drift with outdated dependencies (Node 14, Ember 3.26.1), many TODO comments, and incomplete features (e.g., voting, QR login transfer). The pinochle game app appears experimental but demonstrates sophisticated state machine usage and animation systems.
aTox is an Android client for the Tox peer-to-peer instant messaging protocol. It provides encrypted text messaging, audio/video calls, file transfers, and group chats using the decentralized Tox network. The application follows a clean multi-module architecture: the `domain` module contains pure Kotlin business logic (Tox wrappers, feature managers, validators), the `core` module handles local persistence via Room database (contacts, messages, file transfers, friend requests), and the `atox` module implements the Android UI using Dagger dependency injection, ViewModels, LiveData, and Navigation component. Key entry points include `MainActivity` for handling intents and navigation, `ToxService` for running the Tox loop in a foreground service, and `EventListenerCallbacks` for bridging Tox events to database updates and notifications. External dependencies include the `tox4j` JNI bindings to `c-toxcore`, libsodium for encryption, and opus/libvpx for audio/video codecs. The repository is explicitly unmaintained and carries significant technical debt from its complex Bazel native build system, outdated library versions, and potential security risks inherent in the Tox protocol itself.
