Blockchain

What is the Blockchain?

A Secure Ledger

Every record has a unique, unhackable identifier

The record lists the details of the transaction

The next record references the identifier from the previous record, chaining the records together

We can see who wrote the record, i.e. every record is time-stamped and signed by the parties

Miners solve a complex puzzle to add the record to the blockchain

“Trustless” - All of these steps can be verified, minimizes trust from any single actor in the system. Trust is distributed to different actors in the system.

Crypto Currencies vs. Blockchain

Bitcoin is a digital, decentralized currency allowing for safe secure transfers between users directly

Bitcoin is structured as a blockchain

A blockchain is a distributed ledger that maintains immutable records cloned on many nodes across a network.

Blockchains have been employed by companies since the early 2000's and can be used to better track inventory, the movement of disease, or settle payments quickly.

Concepts to Note

Different industries—different chains(finance, ag, health, government, etc.)

Each ecosystem is promoting their own blockchain – Ethereum, Bitcoin, etc.

Blockchain replaces intermediaries

(e.g. All transactions can be verified)

Reputational Opportunities(e.g. your score goes up as you transact more, reviews can’t be forged or altered)

The government of Kerala in India is planning to introduce blockchain in the grocery supply process, ensuring that the system will be used whenever food is

being delivered to stores across the country.

Use Case in Agriculture

Goals:

Deliver products to millions of people on a daily basis more efficiently

Provide a form of “crop insurance” to ensure that farmers can be compensated quickly whenever unforeseen circumstances affect their yield.

Ex. Supply Chain Process for Shipping Produce; US to France:

• Grower grows and packs the oranges

• Carrier (trucking company) ships the Oranges to Destination #1 (e.g. Port of Miami) (e.g. 3 day trip)

• USDA inspection of the fruit occurs

• Bins are loaded into the refrigerated Shipping Containers at the Port

• 10-14 days at sea – Temp, humidity, env. monitored carefully

• Delivered to overseas (final) destination where they are inspected again

Potential Use Case – USDA - PACA

USDA/AMSPerishable Agricultural Commodities Act (PACA)

• It is important that each event along this supply chain is tracked and verified.

• Temperature readings can be sent, check-ins at various destinations, inspections

• At the final destination, when the produce is inspected, they may find decay or quality issues.

• In a dispute, who takes responsibility? Did the shipper follow proper procedure? Info can be reliably and immutably verified using blockchain

• With blockchain the details of the transactions (who, what, when, where, how, etc.) can not be tampered with after being recorded in the blockchain, increasing confidence in the data.

• Due to sheer size the healthcare industry requires the recording of a massive amount of protected, verified, and sharable data. Countless transactions across patients, professionals, and institutions need to be precisely documented and managed. From just a cost standpoint, $250 billion is annually spent on healthcare transactions alone, which the implementation of blockchain technology should reduce significantly.

• 80% of mistakes made in the healthcare industry are administrative in nature, harming an estimated 400,000 patients every year. Researchers claim that the healthcare industry can be improved by incorporating blockchain technology, reducing human error and cutting transaction costs through a distributed ledger.

Use case in Clinical Health Care

Benchoufi M, Porcher R and Ravaud P. Blockchain protocols in clinical trials: Transparency and traceability of consent

Blockchain – Informed Consent

Reducing human error by making

steps in the IC protocol verifiable.

Meaning pts can’t say “I didn’t

consent”, and investigators won’t

treat patients without consent…

Improves Transparency – All

designated parties can see who

signed the consent and when

Blockchain use cases are seen across all industries

Blockchain helps to greatly increase the “trust factor” between parties

Has the ability to revolutionize any industry that involves transactions - Hundreds of K transactions on ecommerce sites, Uber, AirBnB, HealthCare and Organic Labelling in foods

Experience in the private sector will lead to improved governance in public sector
