Decentralized Control Plane +Megatorrent uses the Mainline BitTorrent DHT (BEP 44) for all control operations. + +### 1.1 Identity +* **Users:** Identified by Ed25519 Public Keys. +* **Channels:** A channel is simply a stream of updates signed by a specific Identity. + +### 1.2 Manifests (Mutable Items) +* Content metadata is stored in a JSON **Manifest**. +* Manifests are published to the DHT as Mutable Items (`salt` optional, `seq` monotonic). +* **Structure:** + ```json + { + "publicKey": "", + "sequence": , + "signature": "", + "collections": [ ... ], + "encrypted": false // or true + } + ``` +* **Private Channels:** If `encrypted: true`, the content payload is encrypted with ChaCha20-Poly1305 using a shared secret (Read Key). + +### 1.3 Blob Discovery +* Files are split into chunks, encrypted, and hashed to create **Blobs**. +* **Blob ID:** SHA256(EncryptedBlob). +* **Announcement:** Peers announce Blob IDs to the DHT via standard `announce_peer`. +* **Lookup:** Peers find locations via `get_peers` (DHT) or PEX. + +--- + +## 2. Encrypted Transport (Anonymity) +All peer-to-peer traffic is wrapped in a custom encrypted transport layer to prevent Deep Packet Inspection (DPI) and traffic analysis. + +### 2.1 Handshake (Noise-IK Simplified) +1. **Client:** Generates Ephemeral X25519 (`EphPub`). Sends to Server. +2. **Server:** Generates Ephemeral X25519. Sends to Client. +3. **Key Derivation:** Both derive `Tx`/`Rx` keys using BLAKE2b on the ECDH shared secret. + +### 2.2 Framing +* Packet: `[Length (4B)] [Ciphertext (Payload + 16B MAC)]` +* Cipher: ChaCha20-Poly1305. + +### 2.3 Protocol Messages +* `MSG_HELLO (0x01)`: Handshake completion + Gossip (JSON payload of known sequences). +* `MSG_REQUEST (0x02)`: Request a Blob by ID (ASCII). +* `MSG_DATA (0x03)`: Binary Blob Data. +* `MSG_FIND_PEERS (0x04)`: Request PEX for a Blob ID. +* `MSG_PEERS (0x05)`: List of peers (JSON). +* `MSG_PUBLISH (0x06)`: Request Peer (Gateway) to publish a Manifest to the DHT. +* `MSG_ANNOUNCE (0x07)`: Announce own address (e.g., .onion) to Peer. +* `MSG_OK (0x08)`: Generic Success Acknowledgement. +* `MSG_DHT_QUERY (0x09)`: Encapsulated KRPC Query (Bencoded). +* `MSG_DHT_RESPONSE (0x0A)`: Encapsulated KRPC Response/Error (Bencoded). +* `MSG_ERROR (0xFF)`: Error message. + +--- + +## 3. Traffic Analysis Resistance +* **Fixed-Size Blobs:** All blobs are padded to exactly `1MB + 16 bytes`. +* **Random Padding:** Unused space in a chunk is filled with random noise before encryption. +* **Result:** An observer cannot distinguish between a text file and a video segment, nor infer file size from packet lengths. + +--- + +## 4. Redundancy & Resilience +* **Active Seeding:** Clients automatically re-announce downloaded blobs to the DHT every 15 minutes. +* **Gossip:** Clients exchange subscription state (`latestSequence`) upon connection, allowing updates to propagate instantly (Push) without waiting for DHT polling. + +--- + +## 5. Tor Integration & Dark Swarms +* **SOCKS5:** The Reference Client supports SOCKS5 proxies (`--proxy`). +* **PEX Fallback:** Since Tor cannot carry UDP (DHT), clients behind Tor use `MSG_FIND_PEERS` over the encrypted TCP connection to discover content via their peers. +* **Remote Publishing:** Authors behind Tor can use `MSG_PUBLISH` to instruct a Gateway node to write to the public DHT on their behalf. +* **Hidden Service Announcing:** Nodes can announce `.onion` addresses via `MSG_ANNOUNCE`, creating an invisible swarm overlay accessible only via Tor. + +--- + +## 6.
