Smart Network Economics:
Debt, Risk, and Payment Channels
Smart networks are intelligent autonomous networks, a new form of global computational infrastructure in which intelligence is built directly into the software such that an increasing degree of autonomous operation is facilitated. More formally, smart networks are state machines that make probabilistic guesses about reality states of the world and act upon this basis, particularly in economic domains, hence, smart network economics.

Payment Channels: the concept
8
Ability to “have an account” relationship with any party
3-step financial contract executed over time
1. Party A opens a payment channel with Party B and posts a
pre-paid escrow balance
2. Party A consumes against the escrow credit over the given
time period (activity is tracked)
3. At the end of the period, cumulative activity is booked in one
net transaction to close the contract

1. Unilateral Payment Channels
Starbucks Example
1. Customer opens $50 monthly payment
channel with Starbucks
2. Daily coffee consumed is tracked and
booked against the $50 credit
3. Activity is netted at the end of the month.
Contracts close and roll over at regular
intervals. Either party may close the
channel early, trigger net settlement

7. MySupplyChain Payment Graph Economy
Blockchains: only sub-registers of the cash
account (Alice, Bob, HSBC, etc.), not a full
suite of general ledger accounts
Property registries use cash-acct ledger structure
Property registries where UTXOs are assets
Birth/death registry: one credit tx, one debit tx
Supply chain finance: for supply chain net
settling, need integrated account ledgers
Single set of books with multiple views: by supply
chain (new) + by entity (existing)
Revenue (WMT); COGS (Deere, Adidas)
