Blockchain
Payment Channels: the concept
1. Network is a graph (vertices, edges)
 Payment, credit, transaction graph
2. Net clearing
 Contracts-for-difference (CFD); (without the 10x
options-style leverage of the financial instrument)
 Spread betting
 Net settlement (vs Gross settlement)
 Central banks clear amongst themselves with RTGS
(real-time gross settlement) systems (as does
Ripple)
 Industry consortia, interbank daily settlements are
tabulated on a net basis
3. “Have an account,” “run-a-tab” economy

Blockchain
What is a Payment Channel?
 3-step financial contract executed over time
1. One party opens a payment channel with another
party and posts a pre-payment escrow balance
2. The party consumes against this 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

Blockchain
What is a Payment Channel?
 Motivation
 Improve scalability through contractually-obligated
relationships booked as periodic net activity
 Micropayments mechanism for video bandwidth consumption
where piecemeal transactions do not make sense
 Current ~$175 max (4% Btc) for Lightning Payment channels
 Bigger implication
 Might develop into a digitized payment system for resource
consumption that settles based on net payments instead of
gross transfers, and enables peer-to-peer banking services
 Sophisticated functionality
 Concatenated payment channels, time/signature lock
parameters (CheckLockTimeVerify, CheckSequenceVerify)

Payment Channels: Level 1
 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

Accounting and Legal Treatment?
 Promise of cryptocurrencies as
“programmable money” in implementation
 A contingent three-part financial contract over
time is a new instrument
 Financial contract feature sets:
 Prepayment risk
 European/American-style option execution
 Fractional reserves
 Accounting: deferred payment, installment
sale? Revenue recognition, liability?
 Legal: assignments of claims, forward-
looking IOUs?

Payment Channels: Level 2
 Small group concatenated payments example
 Local bar: Lynn, Chris, Bartender
 Lynn has a $10 tab with bartender, has consumed $6
 Chris has a $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

Payment Channels: Level 3
 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

My supply chain: 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 Channels: Level 5
 “Mike Hearn” example
 Farther-future possibility of auto-instantiating
self-driving cars and other smart network
resources
 Smart network instantiates banking
services directly (sensing network
demand, auto-instantiates, provides
services, retires when necessary)
 Network node does not need to be
human-backed (technically)
 Historically-vested grounding of roles,
responsibilities, taxation in legal personhood

Implications
 With money and payments digitized, and activity
being securely forward-committed by payment
contracts, the implication is that net flows instead of
gross flows might be transferred
 An economy based on net clearings rather than gross
transfers could mean more activity and less debt
 Rethink Debt
 Streaming money (Antonopoulos) could be disgorged in
much smaller chunks that are more closely tied to costs and
repayment possibilities
 Challenge: how to construct net rather than gross
obligations for home mortgage, student loan, public works
projects, bond offerings?

Modes of consumption: pre-pay vs post-pay
 Rethink modes of consumption: pre-pay vs post-pay
 Pre-paid consumption (a small part of current overall
economic activity) against the much larger portion of activity
that is post-paid and based on credit and terms
 Two-thirds of the economy tied up in supply chain finance
 Incentive is to play the float; instead, incentive to net out
 Digitized streaming money and payment channels could be
techniques to quicken the 30-60-90 day terms and
uncollectible debt problem in supply chain finance, and
facilitate a just-in-time economy for money

Conclusion
 How can we use these concepts and tools to
solve a larger class of economic problems?
 Economic incentive counter to outcome
 Supply chain: play the float
 Maximization not price rationalization in health care
 Entitlements (payment channel for social security?)
 Income inequality, digital divide
 Automation economy, technological unemployment
 Have to own investment assets
 Saas (securities as a service): access to consumable
benefits of an asset without having to own the underlying
(Spotify, Hulu, Uber, Airbnb)

Payment Channel impact
 Digitized money and payments, and activity securely
forward-committed in payment contracts
 Implication: economy could settle on the basis of net
rather than gross flows
 A net-clearings contracts-for-difference economy could
rethink crippling monolithic debt structures with streaming
money disgorged in much smaller chunks more closely
tied to costs and repayment possibilities
 Pre-paid consumption and 30-60-90 day vendor credit
terms models could be offset to facilitate a directed
payment graph economy of just-in-time money

What is Blockchain/Distributed Ledger (DLT)?
29 Oct 2017
Blockchain 46
Distributed Ledger (general form of DLT):
(1) shared transaction database among network
members, (2) updated by consensus, (3) records
timestamped with a unique cryptographic signature,
(4) in a tamper-proof auditable history all transactions
Distributed Ledger Technology vs. Blockchain
Blockchain (specific DLT w additional feature):
(5) Sequential updating of database records per
chained cryptographic hash-linked blocks

What is Bitcoin mining?
54
 Mining is the accounting function to record
transactions, fee-based (lucrative 25 Btc/bl)
 Mining ASICs “find new blocks” (proof of work)
 Network regularly issues random 32-bit nonces
(numbers) per specified cryptographic parameters
 Mining software constantly makes nonce guesses
 At the rate of 2^32 (4 billion) hashes (guesses)/second
 One machine at random guesses the 32-bit nonce
 Winning machine confirms and records the
transactions, and collects the rewards
 All nodes confirm the transactions and append the
new block to their copy of the distributed ledger
 Security via entropy + proof of work
Sample
code:
Run the software yourself:
Fast because ASICs

What is Economics?
 Study of the production, distribution, and
consumption of goods and services
 Individual and group decision-making about
goods and services and the consequences
 Fundamental dynamics do not change
 Wants are bigger than resources, cost of
decision-making, opportunity cost, scarcity

Economics: Basic Design Principles
61
Economic Principles
 Traditional Deployment
 Markets
 Blockchain Deployment
 Any interaction is a discovery
and exchange process
 Abundance mindset and
overcoming scarcity
 Decentralized models
supplement hierarchy
 Demurrage incitatory potential
and resource redistribution
across network nodes
 Reciprocal mining communities
Blockchain technology is
prompting us to rethink
economic principles in markets,
and apply them much more
extensibly to other situations in
a non-monetary sense

 Analysis (Brynjolfsson et al., 2006, 2010)
 Amazon: niche books account for 36.7% of sales
 Power laws not Pareto distributions in etailing (books,
music), software downloads (70/30 not 80/20)
 Critique (Elberse, 2008)
 Pareto distribution not power laws in some markets
 Evolving market: feedback effect of online reviews

 Same as a Classical Economy
 Underlying dynamics do not change: wants outweigh
resources, cost to decisions, scarcity of valued resources
 Institutions, Money, Nation States persist, change in form
 Assets, identity, & information now become cryptographic
 Different than a Classical Economy
 Hybrid economy of human and computational agents
 Leapfrog technology: financial inclusion and rethink debt
 New economic design principles: long tail, decentralization,
assets as a service, smart contracts

  • 8. 29 Oct 2017 Blockchain Payment Channels: the concept 1. Network is a graph (vertices, edges)  Payment, credit, transaction graph 2. Net clearing  Contracts-for-difference (CFD); (without the 10x options-style leverage of the financial instrument)  Spread betting  Net settlement (vs Gross settlement)  Central banks clear amongst themselves with RTGS (real-time gross settlement) systems (as does Ripple)  Industry consortia, interbank daily settlements are tabulated on a net basis 3. “Have an account,” “run-a-tab” economy 7
  • 9. 29 Oct 2017 Blockchain What is a Payment Channel?  3-step financial contract executed over time 1. One party opens a payment channel with another party and posts a pre-payment escrow balance 2. The party consumes against this 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 8 Source: https://www.psmarketresearch.com/market-analysis/personal-robot-market
  • 10. 29 Oct 2017 Blockchain What is a Payment Channel?  Motivation  Improve scalability through contractually-obligated relationships booked as periodic net activity  Micropayments mechanism for video bandwidth consumption where piecemeal transactions do not make sense  Current ~$175 max (4% Btc) for Lightning Payment channels  Bigger implication  Might develop into a digitized payment system for resource consumption that settles based on net payments instead of gross transfers, and enables peer-to-peer banking services  Sophisticated functionality  Concatenated payment channels, time/signature lock parameters (CheckLockTimeVerify, CheckSequenceVerify) 9 Source: https://www.psmarketresearch.com/market-analysis/personal-robot-market
  • 11. 29 Oct 2017 Blockchain Payment Channels: Level 1  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  SBUX: payment channel prototype  Loyalty program (cards & apps): 41% purchases, $1.2 bn obligations 10 Source: https://www.psmarketresearch.com/market-analysis/personal-robot-market SBUX Balance Sheet Assets Cash $1.2bn Liabilities Stored Value Cards $1.2bn
  • 12. 29 Oct 2017 Blockchain Accounting and Legal Treatment?  Promise of cryptocurrencies as “programmable money” in implementation  A contingent three-part financial contract over time is a new instrument  Financial contract feature sets:  Prepayment risk  European/American-style option execution  Fractional reserves  Accounting: deferred payment, installment sale? Revenue recognition, liability?  Legal: assignments of claims, forward- looking IOUs? 11 Source: https://www.psmarketresearch.com/market-analysis/personal-robot-market
  • 13. 29 Oct 2017 Blockchain Payment Channels: Level 2  Small group concatenated payments example  Local bar: Lynn, Chris, Bartender  Lynn has a $10 tab with bartender, has consumed $6  Chris has a $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 12 Source: Andreas Antonopoulos Bartender A/R Lynn $6 Chris $5 Lynn A/R Chris $5 Bar $6 A/P $1 Chris Bar $5 A/P $10 Lynn $5 $11 Current Method Tx1 $6-Lynn Tx2 $5-Chris Tx3 $5-Lynn Payment Channel Tx1 $10 C-to-B Tx2 $1 L-to-B
