• GossipSub Protocols - Implements the GossipSub protocol for scalable publish-subscribe messaging in blockchain networks.
• Multi-Transport Connectivity - Connects peers over TCP, QUIC, WebSocket, WebRTC, and WebTransport transports.
• NAT Traversal Mechanisms - Traverses NATs using hole punching, automatic detection, and circuit relay fallback.
• Pluggable Transport Backends - Provides a pluggable transport abstraction supporting TCP, QUIC, WebSocket, WebRTC, and WebTransport.
• Swarm Managers - Provides a central swarm manager that coordinates all active connections, protocol negotiation, and peer lifecycle.
• Peer-to-Peer Networking - Locates peers and routes messages without relying on a central directory or server.
• Pluggable Transport Connections - Opens and manages raw peer connections using pluggable transport protocols like TCP.
• Peer Discovery - Discovers peers via DHT, mDNS, and rendezvous points without a central registry.
• Decentralized Discovery Methods - Ships Kademlia DHT, mDNS, and rendezvous point discovery for finding peers without central servers.
• Peer Data Stream Exchanges - Exchanges arbitrary data streams between peers over multiplexed connections.
• Distributed Hash Table Discovery - Implements a Kademlia-based distributed hash table for decentralized peer discovery and provider records.
• Stream Multiplexers - Implements stream multiplexing to run multiple logical substreams over a single transport connection.
• Swarm-Based Coordination - Coordinates transports, protocols, and peer connections through a central swarm manager.
• TCP Transport Connections - Establishes reliable connections between peers using the TCP transport protocol.
• Secure P2P Connection Establishment - Encrypts and authenticates all connections using Noise or TLS 1.3 with automatic certificate management.
• Multi-Transport Frameworks - Supports TCP, QUIC, WebSocket, WebRTC, and WebTransport for cross-platform peer connectivity.
• Noise Protocol Handshakes - Implements the Noise protocol framework for authenticated key exchange and encrypted peer-to-peer data transport.
• Noise Protocol Frameworks - Secures all connections using the Noise protocol framework for authenticated key exchange and encrypted transport.
• Peer Communication Security - Authenticates peers using public-key cryptography and encrypts all traffic with modern cryptographic algorithms.
• SSL/TLS Connection Security - Encrypts and authenticates all traffic using noise handshakes or TLS to prevent eavesdropping and tampering.
• Encrypted Peer-to-Peer Transfers - Encrypts and authenticates all peer traffic using Noise protocol or TLS 1.3 by default.
• Cross-Platform Runtimes - Operates across browsers, mobile devices, and servers with support for multiple transport protocols.
• Connection Upgraders - Applies protocol negotiation and encryption to upgrade raw connections or substreams.
• Custom Protocol Implementations - Supports custom protocol implementation on top of the swarm by defining network behaviours and connection handlers.
• Browser-Based Connectivity - Enables browser-to-browser P2P connections using WebRTC, WebTransport, and circuit relaying.
• mDNS Service Discovery - Discovers nearby peers on the local network using multicast DNS announcements.
• Multiaddress Formats - Provides a multiaddress format for identifying peers and their locations in the network.
• Automatic Port Mapping - Supports automatic port mapping via UPnP to make peers reachable from the internet without manual configuration.
• Peer Metadata Exchanges - Exchanges peer metadata including public keys and supported protocols after connection.
• Rendezvous Point Discovery - Uses rendezvous points for peers to register and discover each other without central coordination.
• GossipSub Mesh Propagation - Implements GossipSub mesh propagation for scalable publish-subscribe messaging in blockchain networks.
• Circuit Relay Hosting - Provides circuit relay functionality to route traffic between peers that cannot connect directly.
• Circuit Relay Connections - Routes traffic through an intermediary node to connect peers that cannot directly reach each other.
• Automatic TLS Negotiations - Automatically negotiates TLS certificates for browser-native peer-to-peer connectivity without manual setup.
• Transport Layer Encryption - Upgrades raw transports with authenticated encryption and compression to secure peer communications.
• Request-Response Exchanges - Provides a request-response messaging protocol for exchanging messages over dedicated streams between peers.
