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."

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.

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

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.

What Is A Bitcoin Wallet? - The Best Explanation EVER
 
04:06
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.

What is UNSPENT TRANSACTION OUTPUT? What does UNSPENT TRANSACTION OUTPUT mean?

What is UNSPENT TRANSACTION OUTPUT? What does UNSPENT TRANSACTION OUTPUT mean? UNSPENT TRANSACTION OUTPUT meaning - UNSPENT TRANSACTION OUTPUT definition - UNSPENT TRANSACTION OUTPUT explanation. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In cryptocurrencies, an unspent transaction output (UTXO) is an output of a blockchain transaction that has not been spent, i.e. used as an input in a new transaction. Bitcoin is the most famous example of a cryptocurrency that uses the UTXO model. Outputs are a superset of UTXOs. Accordingly, UTXOs are a subset of the outputs superset. Bitcoin UTXO lifespans have been studied. In the case of a valid blockchain transaction, unspent outputs (and only unspent outputs) may be used to effect further transactions. The requirement that only unspent outputs may be used in further transactions is necessary to prevent 'double spending' and/or fraud. For this reason, inputs on a blockchain are deleted when a transaction occurs, whilst at the same time, outputs are created in the form of UTXOs. These unspent transaction outputs may be used (by the holders of private keys; for example, persons with cryptocurrency wallets) for the purpose of future transactions.

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, ..

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 101 Ep 17 - Why are Bitcoin transactions charged by bytes?
 
01:15
Our banks usually charge a fee based on a percentage of the transaction amount we are sending. For example, 0.5% for inter-bank transactions. 0.1-1% for transactions across different cities, and for transnational transfers, on top of the commission fees, there are additional cable charges too. For cryptocurrencies, transaction fees are based on the size of the transaction in bytes, not the amount transferred. For instance, an average Bitcoin transaction takes up 250 bytes, the transaction fee will be around 0.001-0.0015 Bitcoin. If you’re sending Bitcoins to multiple addresses in one transaction, then the transaction will be a larger byte size, hence you may want to pay a higher transaction fee, in order to attract miners to process your transaction. Yet, from a cost perspective, it is highly advantageous to utilize blockchain technology for cross-border transactions. Watch the video here! Huobi Pro will post a question in our Tweet via our Twitter account (https://twitter.com/Huobi_Pro) each time we put up an episode of Blockchain 101 post on our Twitter account, we will randomly select 20 people who answered in the format [UIDxxxxxxxx, correct answer] and retweet our post will be entitled to 1 HT each.

How to remain anonymous while using bitcoin
 
01:55
Bitcoin is a cryptocurrency that can help protect your identity when making purchases online. But it's not foolproof. Kevin Mitnick, one of the world's most famous hackers and author of the book "The Art of Invisibility," offers some tips that will help you remain anonymous. Following is a transcript of the video: The whole idea of really being truly invisible is a disconnect between you as the user and your first connection to the internet. If you use bitcoin, there is a blockchain. And the blockchain is really traceable. In fact, during the trial of Ross Ulbricht, the guy that was accused of running the drug emporium Silk Road, they were able to trace millions of dollars of transactions to the wallet on his computer. So to try to anonymize bitcoin, you can go to a bitcoin ATM. You could buy it from person-to-person on the street, which is probably the safest way if you're using a phone that's not really registered to you. Like a burner device. Or you could use services that launder bitcoin. So you could buy bitcoin, for example, with a pre-paid card. You can go to any of the pharmacies, buy prepaid gift cards. You could go to certain sites and actually convert that to bitcoin for a large fee, and then you could go take that bitcoin and launder it even further. They have laundering sites. So you basically send bitcoin to them, and they'll mix it with other people's bitcoins, and eventually send you bitcoin back with a small fee that's deducted from the transaction. And then, when you have this clean bitcoin, you could use it, for example, to top up data cards or to purchase email accounts, where you have to sign up for a subscription, to make it really hard to trace you as the anonymous user behind it.

Mining Bitcoin with pencil and paper

Bitcoins are mined using a cryptographic algorithm called SHA-256. This algorithm is simple enough to be done with pencil and paper, as I show in this video. Not surprisingly, this is a thoroughly impractical way to mine. One round of the algorithm takes 16 minutes, 45 seconds which works out to a hash rate of 0.67 hashes per day.

Financial Transactions In Blockchain

In traditional money transfer transactions for example when a person wants to transfer money to another person, he has to execute that through a middle body such as banks or any other kind of financial institutions. The financial institution act as a guaranteed factor to safeguard the transfer and guarantee the delivery of the money to the recipient against nominated fees agreed upon by both parties. Blockchain technology can perform the same functions without a medium and can take place between the sender and receiver without the intervention of another body with fewer fees and time and more secure procedure. ............................................................................................................

Which cryptocurrency blockchain has the most transactions per day?
 
12:57
Would you join us in discovering which blockchain has the most transactions daily because knowing this helps determine which cryptocurrency truly is valuable and which is likely to be pure speculation? The reason fiat currencies like USD have value is the ability to transact. A key indication of the true value of a currency is how much it is being used. With cryptocurrencies the same rule applies because a currency that has many users sending and receiving money is worth buying while anything that has a low amount of activity is likely overvalued and best to sell. For example, Ethereum actually has more transactions than Bitcoin today but Steem has more than both of them combined even with a fraction of the number of users!
