Ripped from the Headlines! 2

Different than other kinds of value transfer • The Internet is very good at transferring information, but very poor at protecting it. • Centralized databases represent a single point of failure. • Blockchains were developed to protect information in a trustless system. • Digital currency represents incentives for decentralized computers to maintain the Blockchain. 3

Centralized Systems • Account-based online payment systems • Controlled by a single administrating authority • Allow users to store value, transfer funds, receive payments from others • Can deal in fiat or virtual currency • Account for the vast majority of virtual currency transactions

Decentralized Virtual Currency: Bitcoin • Decentralized, peer-to-peer network-based cryptocurrency • Anyone can download the free, open source software • No central issuing authority, monitoring, or oversight

What is Bitcoin? Protocol - /n/ - a set of rules and regulations that determine how data is transmitted in telecommunications and computer networking Bitcoin is a protocol released in January 2009 that uses bits to create consensus among entries in a distributed ledger. In practical effect 'bitcoins' are purely digital 'objects' that are intrinsically limited in amount under mathematical law.

Origin • Whitepaper by Satoshi Nakamoto • Bitcoin: A Peer-to-Peer Electronic Cash System • November 1, 2008: Published on The Cryptography Mailing list at metzdowd.com

What do the rules enforce? A protocol that allows for a triple-entry bookkeeping system utilizing a • distributed peer-to-peer network • It is comprised of the world's largest computing network - larger than the 500 largest supercomputers combined. • Ledger entries can be altered by anyone with the 'private key‘ • Fundamental theorem of cryptography: Anything that can be done with a central authority can be done without one.

Distributed Network 11

Blockchain Defined • Blockchain is a cloud based database shared by every participant in a given system • Blockchain consists of blocks that hold time- stamped batches of valid transactions • Each block includes the hash of the prior block, linking the blocks together • The linked blocks form a chain, with each additional block reinforcing those before it • Think of it as a peer-to-peer ledger

How Blockchain Works Transactions are not valid until added to the Chain. Tampering is immediately evident. The Blockchain is regarded as safe as everyone in the network has a copy.

Public Transaction Ledger •All transactions are published to a public transaction ledger, called the blockchain •Linking real-world identities back to wallet addresses can be difficult

How is BTC initially obtained? In person transactions • (https://localbitcoins.com) – App-based payments – Physical representations (coins, checks, etc) • Exchanges (Coinbase, Bitpay) - registered MSBs Buying/Selling a product for Bitcoin • • Mining (participating in the validation process) • Cypto Currency ATMs: locations (http://coinatmradar.com/) • Online “Faucets”

Exchangers • VC Exchangers : third-party entities that exchange cash, virtual currency, and/or other forms of real money for other forms of the aforementioned currencies • Individuals typically use exchangers to deposit and withdraw money from VC accounts • Accept a wide array of payments, including cash, wires, credit cards, and other VC

Peer to Peer: Moving Value Without an Intermediary YES • Cash • Precious metals and stones • Virtual currency NO • Real estate • Banking • Credit cards • Money transfer businesses • Stored value cards
