7. About This Series – Blockchain Basics
In Dr. Strangelove, a party created a “doomsday machine” that would automatically destroy all life if the machine
detected a nuclear attack on that party. There was no override, and, well, let’s just say that the film is hilarious but
probably not a comedy in a conventional sense. There, if the “network” received certain information, the device would
activate. Like a smart contract on a blockchain, the problem in Dr. Strangelove was that the party that created the
doomsday machine activated it before telling its adversary (i.e., the other network participant). That “smart contract” was
critically not smart. Blockchain smart contracts (with much smaller but still meaningful stakes) are computer code
designed to adjust automatically the rights and obligations of network participants based upon the inputting of information
to the network, with such information visible to all and inputted per means and procedures agreed upon by all before the
contracts become effective. And thus paper-intensive, multi-step and multi-party transactions, like securities sales,
supply chain coordination, and supply chain finance, might proceed with greater ease and security. Costs could be
lowered, transactional speed quickened, and litigation simplified or evaded entirely. We will examine these areas of
promise.
Each Financial Poise Webinar is delivered in Plain English, understandable to investors, business owners, and
executives without much background in these areas, yet is of primary value to attorneys, accountants, and other
seasoned professionals. Each episode brings you into engaging, sometimes humorous, conversations designed to
entertain as it teaches. Each episode in the series is designed to be viewed independently of the other episodes so that
participants will enhance their knowledge of this area whether they attend one, some, or all episodes.

Blockchain and Supply Chain

10. What is Blockchain?
• A ledger
• Not stored in any one place
• Composed of a decentralized network of nodes
• New data on the blockchain must be verified by a majority of nodes
• Verification occurs by executing energy-intensive cryptographic calculations
• Once validated, a block of data is added to the chain
• Blocks may never be removed or edited
10

11. What is Blockchain?
• Decentralized – data on the blockchain is not stored in any single place but distributed
across many nodes
• Immutable – once data is added to the blockchain, it cannot be removed, edited or
backdated
11

12. Types of Blockchains
• Public Blockchains (permission-less)
• Private Blockchains (permissioned)
12

13. From Centralized Ledger to Decentralized
• Blockchain establishes a decentralized ledger, by contrast to the familiar centralized
ledger, with a custodian or administrator being trusted to process monetary transactions and
manage the transfer of property
• See the two diagram on the following pages, from David Sneyd, “Blockchain solutions to
ESG problems” (BMO Global Asset Management, Oct. 2018)
13

14. 14
From Centralized Ledger to Decentralized

15. How Does Blockchain Establish a Decentralized Ledger?
• Participant makes an entry, i.e., creates a new block
• Proposed transaction is broadcast to each participant on the network
• Validity of the new block is subject to pre-set criteria and a complex algorithm called
“proof of work”
• A majority of miners conclude that transaction is valid
• New block is created and time-stamped
• All are provided with an updated version of the ledger:
15

16. How Does Blockchain Establish a Decentralized Ledger?
16

17. Some Components of a Blockchain
• Each block contains:
✓ A “hash,” which is a digital fingerprint or unique identifier
✓ Time-stamped batches of recent valid transactions
✓ And the hash of the previous block
• The previous block hash links the blocks together and prevents the past form being
altered or rewritten
• Each subsequent block strengthens the verification of previous blocks (and the entire
blockchain)
17

18. Some Components of a Blockchain, 2
• Proof of work requires high computational capacity, provided by “miners”
• Miners supply the network with computing power, to allow the updating of the database
• A majority of mining power must be able to confirm the new blocks by decrypting the data
• Once a “block” (a record of a purchases and sales created by miners by solving a
mathematical puzzle that validates the transactions) is added to the network ledger of
older transaction (the “chain”), such record on the blockchain can’t be changed or
reversed (i.e., the transaction is immutable)
• Thus a blockchain, to be non-falsifiable, must not have any operator holding at any time
more than half of the computational power of the chain
18

19. According to Satoshi
• A coin can be defined as a chain of digital signatures
• The input to each transaction is the output of one or more other transactions
• The balance in your Bitcoin wallet is the sum of your unspent transactions
• The coins in your wallet can be traced all the way back to the miner that mined it
19

20. So What is Gained by Going from a Centralized to a
Decentralized Ledger?
• If a bank or credit card company keeping a centralized ledger is hacked, then other
participants lose access to their data
• With a decentralized ledger, all participants keep a copy of the data
• With a decentralized ledger, there is no extra cost of (or litigation from) efforts to
synchronize records kept by counterparties to a transaction
20

21. Smart Contracts
• Smart contracts are “self-executing contracts with the terms of the agreement between [a]
buyer and seller being directly written into lines of code. Once a smart contract has been
created, computer transaction protocols will execute the terms of a contract automatically
based on a set of conditions.” Rensel v. Centra Tech, Inc., 2018 WL 4410110 at *10 (S.D.
Fla. June 14, 2018). The promise re smart contracts:
✓ Self-executing
✓ Additional parties not needed to monitor the transactions
✓ Greater cost efficiency and faster transaction speed
• To determine whether contractual conditions are met, smart contracts use “oracles,”
which are agreed-upon real-time data providers which confirm triggering events
21

22. According to the CDC
• Each year, 48 Million Americans are sickened by a Food Bourne Illness.
• Globally, over 600 Million People are affected.
• The problem causes $55 Billion to $90 Billion in economic loss Each year.
22

23. Blockchain Solution
• Food Traceability is a series of inputs & outputs.
• Blockchain stores data in terms of inputs and outputs.
• Blockchain transfers assets across identities.
• Blockchain nodes are public, protected, and easy to implement.

24. 24

25. A Proposed GS1 Numbering System that Works with
Blockchain
• PTI label is the GS1 formatted label that goes on around 60% of all produce sold in the
US. GS1 is a worldwide organization: its website for the US is https://www.gs1us.org/
✓ All companies that sell in a store are members of GS1: the UPC barcode is managed by
GS1
✓ The GTIN (Global Trade Identification Number) uniquely identifies items worldwide
✓ Items can be identified on the blockchain by address, GTIN, and lot number
✓ GLN is global location number representing each factory or shipping location
✓ Companies that sell at retail and need UPC codes for their products must join GS1
✓ Others on the supply chain join because a party requires it (adoption rate declines earlier
in the supply chain)
25

26. Supply Chain, End to End
• Hundreds of shipping links
• Thousands of vendors, manufacturers, distributors, customers
• Data validation, chain-of-custody reporting, supplier
benchmarking, risk heat maps and alerts, emergency response
• The above parties and factors interact dynamically
• A dashboard display might be needed for “visibility” of a simple supply chain, with data
shifting in real-time
26

27. Supply Chain Desiderata
• Provenance of goods (quality, safety, compliance with norms and regulations re:
environmental and labor and other factors)
• More accurate forecasts and product adjustments
• More efficient allocation of talent and capital assets
• More accurate and efficient inputs for financing supply and insuring credit
27

28. Blockchain-Managed Supply Chain: A Few Key
Components
• Purchase Orders
• Ocean Bill of Lading
• Automated Manifest System (required to be field for goods entering the US)
• Importer Security Filing (same)
• Customs Clearance (same)
28

29. Blockchain-Managed Purchase Orders on Blockchain
• Create indelible record of each step (block)
• Execute encrypted actions (identification of parties, authentication of transaction, time-
stamping blocks)
• Digitization upon the ledger of aspects of the contractual agreements, i.e., smart contracts
• Purchase Orders embed within them many business rules (cover price, currency,
quantities, ship date, Incoterms Rules – which may change over the course of the
movement of goods and components (e.g., production capacity of supplier, changes in
raw material costs)
• As each step in the process is verified, invoices can be triggered by smart contracts upon
proof of delivery, the ID of goods can be verified (or not)
Per “Blockchain for Supply Chain: Smart Contracts & Purchase Order Management” (Amber Road White Paper)
29

30. Smart Contract: Smart Invoices
• Euler Hermes has provided trade credit insurance for over 100 years, and is looking at blockchain-
based “smart invoices” (to help manage transaction for which it provides insurance)
• It experimented with having companies upload their invoices onto the Ethereum “Smart Contract”
blockchain
• When a supplier’s invoice is uploaded, the smart contract “reads” it to learn payment due date,
amount, and the purchaser’s identity
• Smart contract then identifies the network of suppliers for that purchaser
• If the supplier is not paid timely, the smart contract can “decide” (based upon rules coded into it),
whether to send an alert (and what kind of alert) to the other suppliers in the network
• PURPOSE: to forestall other payment defaults, lessen trading with insolvent purchaser, and lower
risk of insurable events
