How transactions are verified in Bitcoin Blockchain - Longest chain rule explained
 
05:08
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.

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?

Cancel BTC Transfer Transaction Blockchain 2019

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. Программа эксклюзив и Аналогов НЕТ, потому прошу помочь мне в развитии и скинуть немного $ на кошелек 1qzxMbY2g9dnAkRzx3xvBu8Pme1ApnWpc

How are transactions stored (and recorded) in the Blockchain blocks? Using a concept called a Merkle tree - in this video I break it down in depth with a simple example and show how a SPV node (Simple Payment Verification) node that does not keep a full copy of the blockchain transaction history - just the headers of the blocks - can verify from an adjacent (but not necessarily trusted) full node, which block a transaction is part of just from knowing the MERKLE PATH from the full node. http://chimera.labs.oreilly.com/books/1234000001802/ch07.html

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.

Bitcoin from the Command Line - Sending Bitcoin Transactions Programmatically with Javascript
 
17:07
One of the common complaints with Bitcoin is that it’s pretty hard to get started, and there’s a lot of overhead to making accounts and sending transactions. So I want to show everyone a really simple workflow that I’ve been using to interact with the Bitcoin blockchain from my command line using Javascript. This isn’t a workflow that I would recommend for long-term storage (though there isn’t anything wrong with it necessarily, I still would recommend hardware wallets for long-term crypto-asset storage) but it is a good workflow for hacking around, sending money and building apps.

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.

How To Speed Up A Stuck Bitcoin Transaction

Click below for full links: Note - I'm not crypto expert. I also can't guarantee this will help you. I just shared this video as this is what helped me. I spent $10 ont he first transaction and it went through within 20minutes (after being stuck for 36 hours and still having an ETA confirmation time of 2-3 days). I spent 2 lots of $5 on the second transaction (spread 1 hour apart) and it went through 10 hours later (after waiting 36 hours, with an expected confirmation time of another 24 hours and growing) The site I used was: https://confirmtx.com/ Other sites I use in this video include: - https://blockchain.info/unconfirmed-transactions - https://www.blockcypher.com - https://core.jochen-hoenicke.de/queue/#1w =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= FIND ME: - My blog - https://www.alexfergus.com/blog/ - My website - https://www.alexfergus.com/ - My Newsletter - http://eepurl.com/biaaDf - Instagram - http://aferg.co/2hkaRnv - Facebook - http://aferg.co/2zyEdZK - Youtube - http://aferg.co/2z8N0Sr - #AuthenticAlex Vlog - http://aferg.co/2z9xipY - About Me - http://aferg.co/2hkbjlH =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= STUFF I USE EVERYDAY: - Oura Ring (use code FERGUS to save) - http://aferg.co/1Uk3XN2 - Joovv Light (use code ALEX to save) - https://lddy.no/1efj - Iherb Supplements (use code BHS654 for a discount) - http://aferg.co/2lGseUy - Swannies Blue Light Blocking Glasses (use code ALEX10 to save) - https://aferg.co/swanw9f24f - Hormone Reset Program - http://www.jointheprogram.online Learn more at https://www.AlexFergus.com Learn more at https://www.AlexFergus.com

Signing transactions - Blockchain in Javascript (part 4)
 
18:40
Transactions on a blockchain have to be signed with a private key. This makes sure that people can only spend coins if they have the private key of their wallet. In this video we will refactor our Javascript blockchain so that it will only accept signed transactions. We'll use the secp256k1 elliptic curve to generate a keypair. The same algorithm used in Bitcoin. But you can use other algorithms as well. 🤲 Source code Available on GitHub: https://github.com/SavjeeTutorials/SavjeeCoin 💰 Buy Bitcoin, Ethereum, Litecoin, ..

Analyzing Blockchain and Bitcoin Transaction Data as Graph
 
51:44
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.

This is the first part of a more technical talk where Andreas explores Bitcoin script, with examples from the 2nd edition of Mastering Bitcoin, focusing on the use of conditional statements, flow control, guard clauses and time locks. The examples will include advanced multi-signature scripts, hash time lock contracts and asymmetric revocable commitments. Then he answers questions about Bitcoin's quirky bugs, where Bitcoin differs from Ethereum at a scripting level, how SegWit works, how consensus rules change, and whether Bitcoin is more than just a currency.
