3. How Started
• On 18 August 2008, the domain name "bitcoin.org" was registered.
• In November 2008, a link to a paper authored by Satoshi Nakamoto titled
Bitcoin: A Peer-to-Peer Electronic Cash System
• the bitcoin software as open source code and released it in January 2009
• In January 2009, the bitcoin network came into existence after Satoshi
Nakamoto mined the first ever block on the chain, known as the genesis
block, for a reward of 50 bitcoins, Embedded in the coinbase of this block
was the following text:
– The Times 03/Jan/2009 Chancellor on brink of second bailout for
banks.
• programmer Hal Finney. Finney downloaded the bitcoin software the day it
was released, and received 10 bitcoins from Nakamoto in the world's first
bitcoin transaction.
• Other early supporters were Wei Dai, creator of bitcoin predecessor b-
money, and Nick Szabo, creator of bitcoin predecessor bit gold.
• Nakamoto is estimated to have mined 1 million bitcoins.
• In 2010, Nakamoto handed the network alert key and control of the Bitcoin
Core code repository over to Gavin Andresen
– Nakamoto subsequently disappeared from any involvement in bitcoin.

6. Peer to Peer Networks
• Napster was envisioned as an independent Peer to
Peer File Sharing service by Shawn Fanning. The
service operated between June 1999 and July
2001 (26.4 Million users).
• Unstructured peer-to-peer networks (Gnutella,
Gosip, and Kazaa)
• structured peer-to-peer network implement a
Distributed Hash Table (DHT) which enables peers
to search for resources on the network using a
hash table (BitTorrent , Kad Network, Storm
Botnet, YaCy, and Coral Content Distribution
Network )

7. Overview of Bitcoin Whitepaper

8. Digital currency (Centralized)
• Digital currency (digital money or electronic money or
electronic currency) is a type of currency available only in
digital form, not in physical
• eCach (DigiCash) was an electronic money corporation
founded by David Chaum in 1989.
– eCash (DigiCash) transactions were unique in that they
were anonymous due to a number of cryptographic
protocols
• The E-Gold system was founded by Douglas Jackson and
Barry Downey and launched online in 1996 and had grown to
five million accounts by 2009
• Centralized systems—such as PayPal, eCash, WebMoney,
Payoneer, and cashU will sell their electronic currency directly
to the end user.

9. Digital Currency (Decentralized)
• A cryptocurrency is a type of digital token that relies on cryptography for chaining together digital signatures of
token transfers, peer-to-peer networking and decentralization.
• Bitcoin, the first cryptocurrency, a peer-to-peer electronic monetary system based on cryptography.
• Etherium, an open-source, public, blockchain-based distributed computing platform featuring smart contract
(scripting) functionality.
• Bitcoin Cash, a 2017 fork of bitcoin; main differences from bitcoin are larger blocks, different difficulty
adjustment algorithm, and lack of Segregated Witness.
• IOTA, an open source distributed ledger and an electronic monetary system designed for the Internet of Things.
It uses a Directed Acyclic Grapgh (DAG) instead of a Blockchain.
• Ripple monetary system, a monetary system based on trust networks.
• Litecoin, originally based on the bitcoin protocol, intended to improve upon its alleged inefficiencies. Faster
block times and different mining algorithm compared to bitcoin.
• Dash, originally based on the bitcoin protocol, it offers the option of instant and private transactions. It is a
Decentralized Autonomous Organization.
• NEM, a peer-to-peer electronic monetary system and a blockchain platform which allows for storing digital
assets.
• NEO], an open-source, public, blockchain-based distributed computing platform featuring smart assets contract
functionality.
• Monero, an open source cryptocurrency created in April 2014 that focuses on privacy, decentralisation and
scalability.
• Zcash, a cryptocurrency that offers privacy and selective transparency of transactions.

20. Market survey
• Market grows despite regulatory challenges:
Multiple executive regulators announced
aggressive action, markets boom to all-time high
above $500bn.

debated soft fork resulted in segregated witness,
opened Bitcoin to cryptographic innovations; hard
fork resulted in big block Bitcoin Cash.
