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

Payment Channel motivation and projects
 Motivation
 Micropayments for video bandwidth
consumption where piecemeal
transactions do not make sense
 Blockchain scalability (offload tx)
 Send payments across p2p network
 Projects
 Bitcoin: Lightning Network
 Time/signature lock parameters:
CheckLockTimeVerify,
CheckSequenceVerify
 Current ~$350 max (4% Btc) for
Lightning Payment channels
 Ethereum: Raiden, Plasma

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

 Decentralized DIY energy markets
 Blockchain-based microgrid
 Community:
 Five net-producing homes generating
energy through solar power
 Five net-consuming homes interested
in buying excess energy from
neighbors
 Benefits: no billing components, no
infrastructure losses, no
accounting losses in the system
 Ability for producers to sell or
donate excess

 Local bar: Lynn, Chris, Bartender
 Lynn has $10 tab with bartender, has consumed $6
 Chris has $10 tab with bartender, has consumed $5
 Lynn and Chris play pool, Chris owes Lynn $5
 Current method (gross settlement): each party settles with
each other (3 tx, $16 gross flow)
 New method (net settlement): (2 tx, $11 gross flow)
 Already see implication if less money transfers, more is available

6. MyMonthlyExpense Payment Channel
 My monthly expenses example
 De facto payment channel
 Inflows into bank account:
 Paycheck direct deposit
 Outflows from bank account:
 Auto-pay bills (fixed and variable)
 Formalized into a multi-party payment
contract netting salary against
expenses, any remainder to Schwab
investment account
 Implication: settling net basis frees capital
 Consider business entities on a net basis

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)

Payment Channel implications
 New forms of Digital Credit Systems
 Contractually-obligated payment relationships
 Booked as periodic net activity
 Net settlement
 Digitized payment system for resource consumption that
settles based on net payments instead of gross transfers
 Peer-provided banking services enabled

 Securities a Service
 Now have to own because uncertain future value of assets
 Access to the consumable benefits of the asset without owning

 Need the cash flow the asset provides, not the asset itself
