3. 1. WHAT IS BITCOIN?
27 April 2020 BitCoin Basics 101Page 3
• BitCoin is the first real implementation of Blockchains technology
that have the following attributes:
• Peer-to-peer network that maintains a public decentralized ledger of digital
math-based assets/currency
• The supply of bitcoins is fixed at 21 millions and each bitcoin can be divided into
a hundred million pieces
• The ownership is not interchangeable without instructions from current owner
that have been cryptographically authenticated (digital signatures)
• Though the results look similar to other systems, the way that Bitcoin works is
profoundly different:
▪ Distributed processing
▪ Synchronize records
▪ Smart information
• These attributes have make the Bitcoin network as the financial
network, or the “Internet of Money”

4. 2. HOW BITCOIN WORKS?
27 April 2020 BitCoin Basics 101Page 4
1) Distributed processing
• Every node in the network
checks the work of other
notes
• Confirming transactions
involves solving a small math
problem with random
numbers. Multiple parties
work on this simultaneously
• Transaction are confirmed by
a kind of digital majority vote
• The result is that collusion to
approve fraudulent
transactions is difficult

5. 2. HOW BITCOIN WORKS?
27 April 2020 BitCoin Basics 101Page 5
2) Synchronized records
• Every participant in the
network keeps a copy of all
the transactions
• Transactions are secured by
encryption to prevent
tampering
• Change your transaction
history, and your hash
numbers will be out of sync
with all others, exposing
tampering

6. 2. HOW BITCOIN WORKS?
27 April 2020 BitCoin Basics 101Page 6
3) Smart Information
• Transactions can be sent with
rules attached – small
programs that govern and
how money is delivered

► Satoshi Nakamoto
publishes white
paper titled Bitcoin:
A Peer-to-Peer
Electronic Cash
System via the
“The Cryptography
Mailing List”.
► Satoshi
releases
Bitcoin source
code and
software client
to the world
► Satoshi updates
the source code
and writes
hundreds of
posts totaling
80,000 words
(length of a
novel)
► Satoshi vanishes
from the Internet
after emailing a
developer saying
he had “moved
onto other
things”.
CLUES
• Satoshi Nakamoto is believed to be a pseudonym for the individual or group of individuals responsible for Bitcoin.
No record of a programmer by this name exists prior to Bitcoin
• His P2P Foundation account details say he is a 38-year old male living in Japan.
• In Japanese:
• Satoshi means “clear-thinking” or “wise”
• Naka means “inside” or “relationship”
• Moto means “the origin” or “the foundation
• If an individual, he is a world class programmer with deep knowledge of C++, economics, cryptography and peer-
to-peer networking.

8. 4. WHAT IS BLOCKCHAIN TECHNOLOGY?
27 April 2020 BitCoin Basics 101Page 8
• The open-source software upon which Bitcoin runs (A technology
protocol layer like TCP/IP)
• A distributed database and decentralized
public ledger of all transactions
• Literally blocks (batches of transactions) in a chain, a sequential
ledger of transactions

9. 4. WHAT IS BLOCKCHAIN TECHNOLOGY?
27 April 2020 BitCoin Basics 101Page 9
• String multiple blocks together and you get a BlockChain
• Applications areas:
• Finance and economics: payments, asset exchange
• Exchange of all assets (physical and intangible)

10. • Recording of events
• Medical records
• Identity Management
• Transaction processing
• Documenting provenance
• Financial Transactions
• Marketplace
• Smart Contracts
• Digital Products Marketing
• Property Records
• Voting
• Cloud Storage
