x402 Protocol Integration for Canton #78 - Milestone 2 (Performance Based)

[pedrodneves]

Milestone 2 (Performance Based)

850 MB of total network traffic burned on the Canton Network. At current network conditions, this is estimated to correspond to approximately 380,000 $CC burned, though the actual amount of $CC required may vary over time.
Traffic counted toward this milestone must originate from real usage by users/companies not affiliated with the FTP team.

Milestone	CC Amount	Payment Trigger
Milestone 2	250000 $CC	Upon committee acceptance of delivery

Milestone 2 Delivery — 850 MB network traffic burned

The 850 MB threshold is met: ≥850 MB of Canton MainNet network traffic burned
through live x402 payments settled via our facilitator (Jun 15 – Jul 13), driven
by real agent usage of independent paid services.

Milestone target	Status
850 MB network traffic burned	✅ 850 / 850 MB — met

Real usage

• ~1,435 distinct paying agents over the period

Independent paid services live on x402, paid per request by autonomous agents in
Canton Coin:

• CanTrustAI — LLM inference + image generation (our reference implementation)
• transparentscan — paid on-chain data endpoints
• bitdynamics — liquidity quotes (LaaS)
• noders.team (AppsFactory.cc) — paid news feed

Per-transaction evidence

Two on-ledger exports back the delivered traffic:

1. updateId list — each settlement's on-ledger updateId + timestamp +
   traffic bytes: source
2. full payment detail — the same settlements with merchant, amount, size,
   and status, proving each is a real x402 payment: source

Each updateId resolves on any Canton scan explorer.
