Blockchain 101


What is Blockchain?

  • A decentralized or distributed ledger that verifies transactions
  • These ledgers are shared and synchronized among participants of the blockchain network
  • All participants in the network have a copy of the blockchain
  • Blockchains can be Public or Permissioned

Public vs. Permissioned


  • Analogous to the global internet, open to anyone
  • No privacy but fully immutable
  • No single point of failure


  • Analogous to corporate intranets, permissioned access
  • Provides privacy at cost of security
  • Easier to scale
How do systems compare?

A Chain of Blocks

  • Blockchains consist of a chain of "blocks"
  • These blocks store transaction data that are in a specific order
  • Transactions can represent money, assets, information, etc.
  • Each new block contains a summary or "hash" of the previous block

Consensus Algorithms

  • Blocks are validated by participants in the network through computational power
  • Hashes link the next block
  • Conflicting transactions within a block create a different hash
  • Different hashes are kicked off the main chain by validators through consensus

What Does Blockchain Solve?

Double-spend problem is solved in a decentralized way

  • Opens the door for P2P transactions and distributed asset transfer systems

Transactions are immutable

  • Guarantees that transaction data can't change once submitted to the blockchain, increasing security of data

Transactions are verifiable

  • Anyone in the network can validate a transaction which prevents fraud

Trust Between Parties

  • Blockchains add the dimension of trust to data
  • Data that others can trust
  • This trust can create new value networks and break down information silos internally and externally

What Does Blockchain Mean for Business?

  • Saves time by eliminating reconciliation processes
  • Saves money by reducing or eliminating middleman
  • Reduces risk by providing immutable and verifiable data
  • Creates opportunities for new business models



Blockchain Adoption

  • 6 out of 10 large enterprises expect the technology to be integrated into their systems by Q4 2018
  • $1.2 Billion raised YTD by startups through blockchain token sales (August 2017)

Where Do You Go from Here?

  • Education
  • Find niche use-cases
  • Build prototypes
  • Keep learning
  • Be blockchain agnostic
