Bitcoin Transaction Details - Part 1
 
15:47
A look at how a transaction is constructed This video is part of a larger online course, "From Barter to Bitcoin: Society, Technology and the Future of Money" run by Prof. Bill Maurer and Prof. Donald J. Patterson In addition to the video on YouTube there is a variety of other content available to students enrolled in the class. "In 2008, a person calling himself or herself or themselves Satoshi Nakamoto released a paper suggesting a system for an anonymous, peer-to-peer alternative money. Bitcoin was born. Although not the first digital currency ever proposed, nor the first challenger to fiat money, bitcoin is the first to have captured the broad imagination of speculators, coders, regulators, criminals and the mass media. This course puts Bitcoin in context: how do we understand money as a social, political and technological phenomenon? From discussions of ancient transactions to the rise of state-issued currencies, we will explore the social and technical aspects of bitcoin, its predecessors and potential successors, and how its features echo aspects of many different historical transaction systems. No prior knowledge of economics or computing is required. There is little academic writing on bitcoin. And this may be the first truly academic class on the topic. We want to put bitcoin in a wider perspective, to reflect on what it means for society, politics and economics, as well as how it helps us think about money both a social and a technical phenomenon. This class is not an advanced seminar on bitcoin--we will not be delving deeply into the inner workings of the system, but instead providing a bird's-eye overview with enough technical detail for you to be able to put media stories, hype and hope around bitcoin in perspective. Similarly, this is not a class in monetary economics--we won't go too deeply into monetary theory or policy, the money supply, or inflation. Instead the class invites you to think more deeply about one of the oldest systems of technology on the planet, and most ubiquitous: money, whether coin, cash, credit card or cryptocurrency, we humans have been making money for most of the past 10,000 years. How we do so in the future is a question bitcoin just maybe helps us answer."

The Bitcoin and Blockchain Technology Explained
 
06:16
A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history. ------------------------------------------------------------------- BUY BITCOIN SAFELY HERE: http://bit.ly/BuyBitcoinNow ------------------------------------------------------------------- REGISTER FOR A COINBASE ACCOUNT: http://bit.ly/CoinbaseBitcoinSignup ------------------------------------------------------------------- Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin. Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block. For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes. Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists. These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children. Because a block can only reference one previous block, it is impossible for two forked chains to merge. • How do Bitcoin Transactions Work? http://www.coindesk.com/information/how-do-bitcoin-transactions-work/ ------------------------------------------------------------------- DID YOU LIKE THIS VIDEO? ------------------------------------------------------------------- Enjoy this video?

Blockchain tutorial 27: Bitcoin raw transaction and transaction id
 
12:17
This is part 27 of the Blockchain tutorial. This tutorial explains: - What Bitcoin raw transaction is. - Shows an example of a raw transaction using the very first transaction on the Genesis block. - What the difference is between big endian and little endian. - What a satoshi is. - What a Bitcoin transaction id or hash is and what its purpose is. - How to calculate the transaction id. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

Bitcoin | How it works?
 
09:10
Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator. The network is peer-to-peer and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto and released as open-source software in 2009. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,products, and services. The blockchain is a public ledger that records bitcoin transactions. In this video we will see : - What is Bitcoin - Price of Bitcoin - Why it is important - Digital CryptoCurrency - How bitcoin looks - How can we use bitcoin - Units of Bitcoin - Satoshi - Miners - Blockchain

Bitcoin Cash Explained ( BTC vs BCH )
 
08:04
Bitcoin Cash was launched in August 2017 and since become Bitcoin’s most popular cryptocurrency that has forked from bitcoin network. The reason of this fork is to increase the block size and process more transaction per second. Bitcoin’s maximum block capacity is 1MB, at this current time allows to process 3-7 transactions per second and implications of congested blocks, means paying high fees. Bitcoin’s cash on other hand maximum block capacity is 8MB witch is allowed to process around 60 transactions per second and fees 99% cheaper than original bitcoin. ================================================== 💰Get a Coinbase Wallet! - https://www.coinbase.com/join/5a4bf25...

Tracking Bitcoin Transactions on the Blockchain - SANS DFIR Summit 2017
 
29:09
Bitcoins are a commonly-used currency among cyber criminals for exchanging goods and services and receiving payments from ransomware. While cryptocurrency claims to promote anonymity, the nature of the blockchain’s public ledger means that criminal activities can be traced and correlated. This presentation will cover a brief high-level overview of how transactions on the blockchain work and will focus on how to apply this knowledge in order to both manually and automatically map out transactions, associate bitcoin addresses, and identify potential cybercriminal-owned bitcoin wallets with the goal of providing context to the scale and duration of a campaign impacting your enterprise. Examples will include identifying a Locky affiliate’s infrastructure, attributing the Shark/Atom ransomware, and identifying “bitcoin exchanges” on the blockchain. Kevin Perlow, Associate, Booz Allen Hamilton
