What is “Blockchain”?

A linked list database. Each new block directly references the previous one.

No block can be changed without changing all following blocks.

It is just a new data structure...

What is “Blockchain”?

  • A protocol that that validates no data has been changed corrupted.

  • A network of peer nodes that must come to consensus on the data

  • Incentives that ensure honest behavior

What is “Blockchain”?

Thus we arrive at:

A Distributed ledger that is:

  • Immutable
  • No single point of failure
  • Not controlled or operated by any single entity*
  • Transparent*
  • Permissionless*

* Optional on private network

Once confirmed the ledger is final

...

A open database that we can trust; without trusting anyone using it

What is “Cryptocurrency”?

A record of financial transactions:

  • Self-Sovereign ownership
    • Public-key cryptography
  • No third-party or intermediary needed*
  • Uncensorable*

* Optional on private network

Why Does All This Matter?

7

Blockchains can store anything:

Financial transactions

Identity / credentials / diplomas

Deeds / rights

Permits

News articles / blogs

(Audio/Visual)

...

… So what if we store code?

And a uniform way for anyone to run the same set of instructions....?

“Smart Contracts”

  • Turing complete computer code
    • Pre-programmed terms & conditions
    • Can include storage and�transfer of an asset

  • A decentralized network stores and validates programs
    • Immutable and transparent
    • Terms are final on issuance

How can Blockchain Benefit my Business?

Healthcare

Individual ownership and conditional provisioning of specific pieces of information.

Supply Chain

Real time tracking of products through all touch points - B2B transactions are trustless.

Digital Identity

Self sovereign ID without providing verified documents.

Energy Market

Smart metering of electricity generated specific sources (solar)

Asset Tokenization

Tokenized assets and cheaply and efficiently fractionalized, traded and settled on chain.

SO much more....

- Banking & Finance

- Regulatory Compliance and Audit

- Prediction Markets

- User data Markets

CAUTION: Do you NEED Blockchain?

  • Blockchain is not a “magic bullet”

  • Cost from computational resource used
    • Very expensive vs. off-chain methods
    • A truly smart contract has everything possible optimized and off-chain

  • Bugs may result in loss of assets!!!
    • DAO hack = 3.6 M ETH stolen�(~$250M at the time)
    • Accidental transfers that burn assets

Big Opportunities for Startups

  • DLTs need core development
  • UI/UX work is critically needed
  • Great ideas have minimal competition
    • Most were startups recently!
  • Demand for privacy, security, and decentralized alternatives
  • Use of cryptocurrency reduces overhead
    • Not a product, but a great tool!

  • Welcoming and talented community
