What is Bitcoin?
Monday, April 22, 2019 4
Decentralized open-source peer-to-peer
payment network or protocol that is
powered by its users with no central
authority or middlemen.
Who created Bitcoin?
• The first Bitcoin
specification and proof of
concept was published in
2009 in a cryptography
mailing list by Satoshi
Nakamoto.
• Satoshi left the project in
late 2010 without revealing
much about himself.
• The community has since
grown exponentially
with many
developers working on
Bitcoin.

Bitcoin: A Peer-to-Peer Electronic Cash System
Satoshi Nakamoto
satoshin@gmx.com
www.bitcoin.org
Abstract. A purely peer-to-peer version of electronic cash would allow online
payments to be sent directly from one party to another without going through a
financial institution. Digital signatures provide part of the solution, but the main
benefits are lost if a trusted third party is still required to prevent double-spending.
We propose a solution to the double-spending problem using a peer-to-peer network.
The network timestamps transactions by hashing them into an ongoing chain of
hash-based proof-of-work, forming a record that cannot be changed without redoing
the proof-of-work. The longest chain not only serves as proof of the sequence of
events witnessed, but proof that it came from the largest pool of CPU power. As
long as a majority of CPU power is controlled by nodes that are not cooperating to
attack the network, they'll generate the longest chain and outpace attackers. The
network itself requires minimal structure. Messages are broadcast on a best effort
basis, and nodes can leave and rejoin the network at will, accepting the longest
proof-of-work chain as proof of what happened while they were gone.
1. Introduction
Commerce on the Internet has come to rely almost exclusively on financial institutions serving as
trusted third parties to process electronic payments. While the system works well enough for
most transactions, it still suffers from the inherent weaknesses of the trust based model.
Completely non-reversible transactions are not really possible, since financial institutions cannot
avoid mediating disputes. The cost of mediation increases transaction costs, limiting the
minimum practical transaction size and cutting off the possibility for small casual transactions,
and there is a broader cost in the loss of ability to make non-reversible payments for non-
reversible services. With the possibility of reversal, the need for trust spreads. Merchants must
be wary of their customers, hassling them for more information than they would otherwise need.
A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties
can be avoided in person by using physical currency, but no mechanism exists to make payments
over a communications channel without a trusted party.
What is needed is an electronic payment system based on cryptographic proof instead of trust,
allowing any two willing parties to transact directly with each other without the need for a trusted
third party. Transactions that are computationally impractical to reverse would protect sellers
from fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In
this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed
timestamp server to generate computational proof of the chronological order of transactions. The
system is secure as long as honest nodes collectively control more CPU power than any
cooperating group of attacker nodes.

Who controls the Bitcoin network?
• Nobody owns the Bitcoin
network much like no one
owns the technology
behind email.
• Bitcoin is controlled by all
Bitcoin users around the
world.
Monday, April 22, 2019 9
Who controls the Bitcoin network?
• Users are free to choose what
software and version they use. In
order to stay compatible with
each other, all users need to use
software complying with the
same rules.
• Bitcoin can only work correctly
with a complete consensus
among all users. Therefore, all
users and developers have a
strong incentive to protect this
consensus.
Monday, April 22, 2019 10
Blockchain - How does Bitcoin work?
• From a user perspective, Bitcoin is nothing more than a mobile app or
computer program that provides a personal Bitcoin wallet and allows a
user to send and receive bitcoins with them. This is how Bitcoin works for
most users.
• Behind the scenes, the Bitcoin network is sharing a public ledger called the
"block chain". This ledger contains every transaction ever processed,
allowing a user's computer to verify the validity of each transaction.
• The authenticity of each transaction is protected by digital signatures
corresponding to the sending addresses, allowing all users to have full
control over sending bitcoins from their own Bitcoin addresses.
• In addition, anyone can process transactions using the computing power of
specialized hardware and earn a reward in bitcoins for this service. This is
often called "mining".

Merkle tree is a hash tree in which every non-leaf node is labelled with the cryptographic hash of the
labels or values (in case of leaves) of its child nodes. Hash trees allow efficient and secure verification
of the contents of large data structures. Hash trees are a generalization of hash lists and hash chains.

ERC20 token
• ERC stands for Ethereum Request for Comments. This is an official protocol
for proposing improvements to the Ethereum network. '20’ is the unique
proposal ID number.
• ERC20 defines a set of rules which need to be met in order for a token to
be accepted and called an 'ERC20 Token'. The standard rules apply to all
ERC20 Tokens since these rules are required to interact with each other on
the Ethereum network. These tokens are blockchain assets that can have
value and can be sent and received, like Bitcoin, Litecoin, Ethereum, or any
other cryptocurrency.
• The difference between these tokens and a standalone currency like
Litecoin is that ERC20 tokens piggyback on the Ethereum network, hosted
by Ethereum addresses and sent using Ethereum transactions.

Basis investment principles
1. Invest in what you can afford to lose. This is a very risky investment. You may lose all what you put!!
2. Buy gradually and sell gradually. It’s extremely difficult, if not impossible, to know if you are buying or
selling at the best time
3. Don't enter in the peak value (ATH) of coin if you have no idea about the achieved target (never buy
when people rush into buying)
4. You should educate yourself technically. Learn about the coins you are buying. Know what you are
buying
5. If you want to make good gains you should be engaged
6. Patience is the key to success
7. Never panic, never sell in loss , you didn’t lose if you didn’t sell
8. Don't fall in love with one coin, have a bag of coins (liquid ones)
9. Don't worry if the market goes down due to bad news (this is actually the best time to get in)
10. Don't invest in a dead coin
11. Trade at your own risk. Trading is a full time job!
12. So far long-term investors were the best winners

  • 4. What is Bitcoin? Monday, April 22, 2019 4 Decentralized open-source peer-to-peer payment network or protocol that is powered by its users with no central authority or middlemen.
  • 5. Who created Bitcoin? • The first Bitcoin specification and proof of concept was published in 2009 in a cryptography mailing list by Satoshi Nakamoto. • Satoshi left the project in late 2010 without revealing much about himself. • The community has since grown exponentially with many developers working on Bitcoin. Monday, April 22, 2019 5 Bitcoin: A Peer-to-Peer Electronic Cash System Satoshi Nakamoto satoshin@gmx.com www.bitcoin.org Abstract. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they'll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone. 1. Introduction Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non- reversible services. With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party. What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party. Transactions that are computationally impractical to reverse would protect sellers from fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions. The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.

  • 9. Who controls the Bitcoin network? • Nobody owns the Bitcoin network much like no one owns the technology behind email. • Bitcoin is controlled by all Bitcoin users around the world. Monday, April 22, 2019 9
  • 10. Who controls the Bitcoin network? • Users are free to choose what software and version they use. In order to stay compatible with each other, all users need to use software complying with the same rules. • Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus. Monday, April 22, 2019 10
  • 11. Blockchain - How does Bitcoin work? • From a user perspective, Bitcoin is nothing more than a mobile app or computer program that provides a personal Bitcoin wallet and allows a user to send and receive bitcoins with them. This is how Bitcoin works for most users. • Behind the scenes, the Bitcoin network is sharing a public ledger called the "block chain". This ledger contains every transaction ever processed, allowing a user's computer to verify the validity of each transaction. • The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses, allowing all users to have full control over sending bitcoins from their own Bitcoin addresses. • In addition, anyone can process transactions using the computing power of specialized hardware and earn a reward in bitcoins for this service. This is often called "mining". Monday, April 22, 2019 11

Monday, April 22, 2019 15 Merkle tree is a hash tree in which every non-leaf node is labelled with the cryptographic hash of the labels or values (in case of leaves) of its child nodes. Hash trees allow efficient and secure verification of the contents of large data structures. Hash trees are a generalization of hash lists and hash chains.

  • 31. ERC20 token • ERC stands for Ethereum Request for Comments. This is an official protocol for proposing improvements to the Ethereum network. '20’ is the unique proposal ID number. • ERC20 defines a set of rules which need to be met in order for a token to be accepted and called an 'ERC20 Token'. The standard rules apply to all ERC20 Tokens since these rules are required to interact with each other on the Ethereum network. These tokens are blockchain assets that can have value and can be sent and received, like Bitcoin, Litecoin, Ethereum, or any other cryptocurrency. • The difference between these tokens and a standalone currency like Litecoin is that ERC20 tokens piggyback on the Ethereum network, hosted by Ethereum addresses and sent using Ethereum transactions.

  • 68. Basis investment principles 1. Invest in what you can afford to lose. This is a very risky investment. You may lose all what you put!! 2. Buy gradually and sell gradually. It’s extremely difficult, if not impossible, to know if you are buying or selling at the best time 3. Don't enter in the peak value (ATH) of coin if you have no idea about the achieved target (never buy when people rush into buying) 4. You should educate yourself technically. Learn about the coins you are buying. Know what you are buying 5. If you want to make good gains you should be engaged 6. Patience is the key to success 7. Never panic, never sell in loss , you didn’t lose if you didn’t sell 8. Don't fall in love with one coin, have a bag of coins (liquid ones) 9. Don't worry if the market goes down due to bad news (this is actually the best time to get in) 10. Don't invest in a dead coin 11. Trade at your own risk. Trading is a full time job! 12. So far long-term investors were the best winners Monday, April 22, 2019 68
