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."

How transactions are verified in Bitcoin Blockchain - Longest chain rule explained Watch our earlier Blockchain videos Blockchain Simplified: https://www.youtube.com/watch?v=LWAYveDotb0&t=1s Blockchain Technology explained: https://www.youtube.com/watch?v=gVLIentRlIk&t=1s Have you wondered how transaction get approved in a Bitcoin block chain? Why you need to wait for 3 to 6 confirmations for the transactions to appear in your wallet. This video attempts to explain how a Bitcoin transaction is approved and the process behind it. Let’s assume Mr. Gobish transferred Bitcoin worth 100$ from one crypto exchange to another. Once he does the transfer, the transaction message is sent to the network and passed around all the network participants which are also called nodes. This is added to the transaction pool. Currently, the transaction is in an ‘unconfirmed’ state. All the transactions in the transaction pool will be in an unconfirmed status. Now we will understand who is a miner. In simple words, those who validate new transactions and record them on the global ledger of Blockchain are called miners and this activity is called mining. To make it simple, let’s assume there are currently 3 miners who are trying to confirm the transactions from transaction pool including Gobish’s transaction of $ 100. Normally miners will select those transactions which will generate a higher transaction fees for them. Currently, the numbers of confirmed blocks in the Blockchain public ledger is 998. Once the miners identify that the 998th block is a valid block they will try to create a candidate block by adding unconfirmed transactions from the transaction pool. Now these miners are trying to add the 999th block. To add the blocks they have to solve a complex mathematical problem. This is known as Proof of Work (POW). Let’s assume all the 3 miners were able to solve this problem and have Proof of Work. Now we have 3 different candidate blocks, let’s call them 999 A, 999B and 999C Now which of these block will form part of the valid block will depend upon the longest chain rule. Let’s understand what is longest chain rule is. Now there are other miners who are trying to create other valid blocks and based upon the speed by which a block is created others miners will keep on adding their blocks on top of the earlier blocks. Here in this case Minor C had a better processor which was able to create a block faster than the miner A and B and hence new blocks were created on top of the block 999C. Now the longest chain is the one created by 999C and it will be keep on adding other blocks like 1000, 1001 and so on as miner C solved the proof of work before miner A and B. So what happens to the blocks 999A and 999B? They have to create the Proof of Work again with new set of transactions from the transaction base. Each confirmations represent adding each block. Each confirmation will take on an average of around 10 minutes or more per block. Applying the longest chain rule and proof of work, unconfirmed transaction will become a confirmed transaction and added to the Blockchain ledger Once the blocks are added miner will receive a transactions fees and block fees which will be the new Bitcoin created as an incentive for approving the transactions. Block rewards will be reducing every year and in the end only transaction fees will be there as new Bitcoins will not be created. We will get in to more details about mining and the incentives in our subsequent video.

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?

This is a free sample lesson from 'The Secrets Of The Bitcoin Triangle' course, where you will 'Discover The 21 Fast Track Ways To Make And Save With Bitcoin (Starting From Scratch)'. You can sign up for the full course at: https://cryptoversity.krtra.com/t/r54RTiOWLIZa A Bitcoin wallet is a piece of software you use to communicate with the Bitcoin network and tell it when you want to send and receive transactions. The best way to understand a Bitcoin wallet is by comparing it to email. Once you have setup an email address you need some kind of software to allow you to send and receive emails to that address. Now this software may be an app on your phone, it may be an app on your laptop or it could even be an app you log into online. With email, you enter the username and password for your email address into the app and that’s how the Internet knows it’s really you that is sending and receive emails to that address. Now of course you tell everyone your email address and you have to do that in order for anyone to send you a message. But just because someone knows your email address, that doesn’t allow them to send email from that address. If they could that would be bad because then they could send emails pretending to be you and cause all kinds of problems. In order to be allowed to send email from a particular email address, you have to know the password. If someone finds out your email password then there’s nothing stopping them from logging in to your email app and sending messages. This is very similar to how a Bitcoin wallet works. Every Bitcoin account has two elements to it. One is called your public address, which is like your email address, and one is called your private key, which is like your password. So just like email, you can give anyone your Bitcoin public address and then anyone, anywhere in the world can send you some Bitcoin. They don’t need to know anything about you. All they need is that public address and they can send money to you. Your Bitcoin private key on the other hand is the one thing you must protect. It’s called your private key for a reason because you should never reveal this to anyone. If someone gets your email password, that’s bad because they can start sending emails from your address, but that’s not quite as bad as someone getting your Bitcoin private key because then they can steal all of your Bitcoins by sending them somewhere else. And just like email, once a Bitcoin transaction has been sent, it’s a one way trip. The only way to get it back would be for the person you sent it to to voluntarily send it back. Bitcoin literally works like digital cash. Once you’ve handed it over, the Bitcoin belongs to that other person. And the same goes for when you receive Bitcoin. Once someone sends it to you, it’s yours and no one can take it from you. The only way they could do that is if they knew your private key. And of course now you know never to give this to anyone.

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.

We all have individual bank accounts, facilitating the transfer of money between individuals. Similarly, a Bitcoin transaction is the transfer of Bitcoins from one Bitcoin address to another Bitcoin address. If you want to send Bitcoin to someone else, you’ll need to enter your Bitcoin address, receiver’s address, amount and transaction fee details in your Bitcoin exchange, wallet or your client interface. Once the details are confirmed, the information will be announced and shared within the Bitcoin network. Every 10 minutes, miners will collect and process all the pending transactions into a new block, marking the completion of one confirmation. Till this point, the Bitcoin has already arrived in the receiver’s address. Nowadays, it takes more than six confirmations to make sure the transaction is valid and considered to be complete.

Blockchain technology and Bitcoin will potentially revolutionize business transactions. Blockchain offers a robust, decentralized platform for privacy and trust. It underlies the digital crypto-currency Bitcoin, which can be exchanged freely and anonymously, without a central authority. Bitcoin transactions - recorded publicly, provide an invaluable dataset to gain insight into the behavior of digital currency and the underlying Blockchain technology. Blocks, transactions with potential multiple inputs and outputs, and flow of bitcoins between addresses, form a sophisticated real-time graph. This talk details a pipeline used to gather bitcoin transaction data and analyze it with powerful graph cloud database technologies. Zhe Wu is an architect working on semantic and graph technologies in Oracle USA. He leads the design, architecture, and development of the inference engine for W3C RDFS/SKOS/OWL in the database, Java APIs for RDF Semantic Graph, RDF triple-level security, SQL-based graph analytics, Property Graph for RDBMS and Hadoop, and more. As an Oracle representative, he has participated in the W3C OWL 2 working group, RDF working group, and UDDI standard committee.

Before we delve into the inner workings of a bitcoin transaction I wanted to explain how the actual bitcoin address is derived from the public key which in turn is derived from the private key. I take through step by step all the steps required to derived the checksums etc and show with a real example of a real bitcoin transaction. Also discuss why checksums are included in Bitcoin addresses in order to eliminate the possibility of characters being corrupted, or modified in transit. This is the cool tool for converted from base 58 encoded value to hex value. http://lenschulwitz.com/base58 Good link talking about base 58 encoding. https://en.bitcoin.it/wiki/Base58Check_encoding

Donwload: https://www.sendspace.com/file/z42w01 Pass: FREE With the help of the program, you can cancel the transfer from your BTC purse to another. Perhaps only in cases where you just transferred money and goes PENDING, in any other cases it will not work! Let's consider an example: You buy product (service), and you ask to pay. You transfer your money to their wallet, they instantly get rid of your account and go to the purse of the seller. The seller will see the transfer in his purse and throw you the goods. You will have a time from 2 to 30 minutes before the confirmation of the transaction to return money to your wallet. As a result, you will receive the goods and your money back. The program is exclusive and there are no Analogues, therefore I ask to help me in development and to throw off a little $ on a purse 1qzxMbY2g9dnAkRzx3xvBu8Pme1ApnWpc ----------------------------------------------------------------------------------------------------------- С помощью программы можно отменить перевод с своего кошелька ВТС на другой. Возможно только в том случаи, когда вы только перевели деньги и идет ПЕНДИНГ, в любом другом случаи не выйдет ! Рассмотрим пример: Вы покупаете товар(услугу), и вас просят заплатить. Вы переводите свои деньги на их кошелек, они моментально спишутся с вашего счета и уйдут на кошелек продавца. Продавец увидеть перевод у себя на кошельке и скинет вам товар. У вас будет время от 2 до 30 мин до момента подтверждения сделки на возврат денег на свой кошелек. В итоге вы получите и товар и свои деньги назад.

A look at the details of the transactions... it gets a little technical, put on your seatbelts. 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."
