Payment Flow
Creator uploads video → ffmpeg → fMP4 → torrent pieces Browser opens channel → 1 on-chain funding TX (263 sats) Video plays → PIECE_PAYMENT per chunk (signed BSV TX each) → 62 off-chain payment updates, each with creator/seeder split Video ends → 1 on-chain settlement TX → Creator: 37 sats (60%) | Seeder: 25 sats (40%) Total: 2 on-chain TXs for 62 micropayments

TECHNOLOGY
Architecture Stack
Payment Channels
Unidirectional nLocktime channels. Leecher signs incrementally larger payment TXs. Seeder holds latest — can broadcast anytime. Only 2 on-chain TXs per session regardless of piece count.
Wire Protocol (BEP 10)
Custom bct_pay extension on WebTorrent wire. Messages: CHANNEL_OPEN, CHANNEL_ACCEPT, PIECE_PAYMENT, PAYMENT_ACK, CHANNEL_CLOSE. Runs alongside standard BitTorrent protocol.
Content Ingestion
MP4 → fMP4 via ffmpeg (frag_keyframe+empty_moov). Pieces aligned to fragment boundaries. Manifest includes pricing, codec info, fragment map. Torrent created with BCT metadata.
Streaming Engine
Sequential piece picker: init → current fragment → lookahead → rarest-first. Buffer manager assembles fragments. MediaSource API bridge for browser playback. Memory eviction for long content.
$402 Payment Gate
HTTP 402 response with payment terms + magnet URI + manifest. Client extracts torrent info, opens payment channel, streams content. Standard $402 protocol (BRC-105).
P2P Swarm
SwarmManager tracks browser peers via WebSocket. Viewers auto-seed via WebTorrent client.add(). Server coordinates payments between peer pairs. Peer discovery via wss:// trackers.

Platform
Split is enforced in every signed payment TX. The seeder cannot cheat the creator because the leecher signs the split directly. Trustless — no intermediary needed.
STATUS
Done vs. Remaining
COMPLETED
  • Payment channel state machine (nLocktime, unidirectional)
  • BSV wallet wrapper (@bsv/sdk v2, WhatsOnChain API)
  • BEP 10 wire extension (bct_pay protocol, 7 message types)
  • Channel manager (multi-peer channel tracking)
  • Content ingestion pipeline (ffmpeg fMP4, torrent creation, manifest)
  • Sequential piece picker + buffer manager
  • Seeder node (WebTorrent, economics tracking)
  • Fastify API server with $402 payment gate
  • Browser player with live payment panel
  • Real BSV mainnet payments (funding + settlement on-chain)
  • Settlement TX validation + broadcast
  • Proof-of-serve (BSM-signed cryptographic receipts)
  • P2P SwarmManager (peer registration, payment routing, WebSocket)
  • Docker deployment to Hetzner (3 videos seeding)
  • 67 tests across 6 test files
REMAINING
  • Electron desktop client (blocked: tsx/ESM loader issue — needs esbuild bundling)
  • Real P2P piece transfer demo (works on paper; localhost too fast for HTTP vs WebRTC race)
  • Wallet connect (1Sat / HandCash browser integration)
  • Creator upload portal (drag-drop video, set price, earnings dashboard)
  • Multi-device P2P test (phone + laptop against Hetzner deployment)
  • Seeder marketplace (browse available content, set bandwidth limits)
  • ClawMiner integration (dedicated hardware seeder node)
  • HTTPS + domain setup for Hetzner deployment
  • Content discovery via DHT (replace HTTP catalog)
  • Bidirectional payment channels (peer-to-peer, not just leecher→seeder)
RESEARCH
Why Every Predecessor Failed
Comprehensive research into every BitTorrent + crypto project. All failed for adoption reasons, not technical ones.
ProjectWhat They TriedWhy It Failed
BTT (TRON)Pay seeders in BTT tokenWallet friction, no bootstrap, SEC lawsuit
Filecoin/IPFSStorage incentivesStorage market, not streaming. No retrieval speed
Theta NetworkVideo CDN via edge nodesProprietary ecosystem, not open P2P
LivepeerTranscoding marketplaceOnly success — but compute, not delivery
AudiusMusic on Solana$6.1M hack, not actually P2P delivery
DTube/DLiveBlockchain video platformsIPFS playback failures, content moderation crisis
LBRY/OdyseeBitTorrent-like + blockchainSEC lawsuit killed it (token = security)
Our Design Decisions (Informed by Failures)
No custom token
Pay in BSV sats. Avoids SEC security classification.
Payment before piece
Prevents freeloading. Seeder validates before release.
No blockchain for discovery
Standard trackers/DHT. Blockchain only for payments.
Users never touch a wallet
Server manages keys. Future: embedded wallet connect.
VOD only, not live
Live P2P has physics problems. VOD works perfectly.
Revenue split in TX
Trustless. Seeder can't cheat creator.

Phase 2: P2P Swarm (In Progress)
SwarmManager built. WebSocket coordination working. Browser peers discover each other via trackers. Need multi-device test against Hetzner deployment to prove real P2P piece transfer + payment.
Phase 3: Electron Desktop Client
Electron shell wrapping existing server. System tray for background seeding. Drag-drop video upload. Wallet management. Blocked on tsx/ESM loader issue — fix: pre-compile with esbuild.
Phase 4: Product Features
Wallet connect (1Sat/HandCash). Creator portal (upload, set price, dashboard). Seeder marketplace. Content discovery via DHT. ClawMiner integration. HTTPS + custom domain.

SUMMARY
Built.
Tested.
Live on BSV.
BitCoinTorrent is the first working implementation of per-piece micropayments for P2P video streaming on Bitcoin SV. Real transactions. Real money. Real protocol.
