The main motivation for publishing this paper is to create a model able to predict bitcoin’s price behavior or, more modestly, able to identify its future values within a confidence interval. Such models exist today for other assets and our thinking is to apply them to bitcoin.
Bitcoin is a digital, decentralized, partially anonymous currency, not backed by any government or other legal entity, and not redeemable for gold or other commodity. It relies on peer-to-peer networking and cryptography to maintain its integrity. 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.
Bitcoin the most popular cryptocurrency is being accepted widely across the globe. The technology associated with bitcoin is a rich technology for the verification of transaction. Blockchain technology offers fast, fraud resistant, efficient, cost effective way to operate peer to peer transaction..
Blockchain concept and technology. How this is becoming the next trend after the Bitcoin, expanding to a myriad of solutions. Smart contracts might be using a public distributed, and encrypted platform to support data persistence.

WSO2Con USA 2017: Keynote - The Blockchain’s Digital DisruptionWSO2
Almost a decade ago, little-known open-source cryptocurrency called Bitcoin made its debut with little fanfare. Its underlying technological innovation has now caught the world’s attention; developers, startups, corporations, academic institutions, and governments are all examining what blockchain technology can solve. Currency, assets, identity, trade settlement, cross-border payments, privacy and regulation are areas being explored. This session will explore the past, present, and future of blockchain technology and how it may influence your business.
Everything you ever needed to know about the bitcoin system all explained in baby language, from how it works to how to get started with creating an account, funding an account setting up mining, creating a secure wallet, e.t.c

Kristof V. explained the basics of blockchain and smart contracts. Starting with the mechanics of bitcoin (introduced by the 2009 paper of Satoshi Nakamoto) he explains concepts of pseudonymisation, encryption, blockchain, mining, and distribution. After skimming high-level through some use cases he moves to "(smart) contracts", using the example of an auction.

Bits, Blocks, and Chains: A Concise Examination of Bitcoin and Cryptocurrency...Richard Givens
An overview of cryptocurrency, with a focus on Bitcoin, and an explanation of the processes involved in creating it, with a focus on novice understanding.
Virtual or digital currencies, with Bitcoin chief amongst them, have been gaining momentum and investment over the last couple of years. Offering an almost costless means of making payments around the globe, virtual currencies have the potential to bring significant disruption to the banking industry. This potential is not lost on either Bitcoin startups or banks themselves. But how does Bitcoin actually work? A peer-to-peer network maintains the “blockchain”, an innovative cryptographic protocol which securely mediates payments between parties without mutual trust. This session will step through the structure of the blockchain, showing how it solves the “double spend” problem and allows decentralised processing of financial transactions. Whether Bitcoin will become the currency of the internet or it’s a bubble that is doomed to burst sooner or later, the blockchain itself will change the face of transactional banking and perhaps other industries along the way.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

8. Bitcoin Protocol is Complex
And requires knowledge of :
1. Hashing
2. Digital Signatures
3. JSONRPC
4. Digital Architecture (general)
5. Finance
6. Sociology (explicitly built into system)
12. Bitcoin transactions
Are like a ledger entry to a global(open)
ledger called the block chain
You own bitcoins if there is a record of
some bitcoins being credited to you in the
ledger
20. Proof of Work Protocol
A proof of work is a piece of data which is
difficult to produce so as to satisfy certain
requirements.
Producing a proof of work can be a
random process with low probability.
21. Bitcoin’s Proof of Work
Bitcoin needs a miner to solve for a proof
which, the hash of, when concatenated
with hash string should have a certain
(predefined) number of preceding zeros.
22. Bitcoin’s Proof of Work
Example (Let challenge = C, proof i = Pi)
Hash(P1C) = fj8wru38wrajfhjafhjka…
Hash(P2C) = fuwu893r98wefjlioas…
…
Hash(PnC) = 000fhf8iaedihuhfuias...
32. MINER
25
+
The miner is allowed to add a
coinbase transaction to every
block she mines as a reward.
This is how new coins are
generated.
Transaction Fee
33. Time taken per block
As per the specification, the network
should come up with a new block every 10
minutes.
This also means that a transaction should
generally take 10 minutes to be
completed.
34. Difficulty Calibration
To ensure 10 minute transaction time, the
difficulty of mining is calibrated every
2016 blocks(or two weeks)
35. Reducing Difficulty
Happens when the network more than 10
minutes per block
The difficulty is reduced by reducing the
number of preceding 0s required in the
proof string
36. Increasing Difficulty
Happens when the network less than 10
minutes per block
The difficulty is increased by increasing
the number of preceding 0s required in
the proof string
