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.

Blockchain/Bitcoin for beginners 8: Bitcoin addresses, public key hash, P2PKH transactions
 
23:28
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

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/Bitcoin for beginners 3: public/private keys, signatures... and first ever transaction
 
36:25
Detailed overview of public/private key encryption and live demo of exactly how digital signatures work on Mac, combining public and private keys and hash functions. Welcome to episode 3 of my series on Blockchain/Bitcoin. I'm joined once again by my girlfriend Nadisha who is my classroom pupil... I build on the hash function concepts from the previous episode and explain the basic concepts public and private keys and how to use them to create digital signatures - a key part of the bitcoin infrastructure. We demonstrate in a Mac terminal how you can generate your own keys and encrypt and decrypt and sign your own resources - learning by doing always works. We touch on bitcoin addresses, what they represent and how they are created. Finally I go back for a refresh of the bitcoin blockchain browser and look at the first ever bitcoin transaction in the "Genesis Block" to show what a real bitcoin address looks like.

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?

Scam site: deepdotmy.com deepdotmy.ru (fake bitcoin transaction generator 1.5.2)
 
03:34
fake project of this site: Bitgen - bitcoin transaction generator 1.5.2 ------------------------------------------------------------------------------------- High risk hacker tools selling fraudulent websites---------------deepdotmy.com deepdotmy.ru------fake tools ----------------------------------------------------------------------------------------------------------- This is a website that specializes in selling hacking tools. It includes pay tools and free tools. Free tools basically come from collecting online free hacking tools and publishing their own websites. This includes a large number of tools that contain viruses. The price of the payment tool ranges from 50 US dollars to 500 dollars, of which the most popular one is a bitcoin software, bitgen. The software sells for $50 a month. I bought this software this year as entertainment, and it took me about twenty days to install it. Finally, it has failed. During this period, I turned to many professional programmers for help. So I contacted their so-called technical support staff and paid 100 US dollars for the cost of the appointment installation. But after paying the money and waiting for 10 days, there is still no installation staff to contact me. From this time, I think this thing is highly suspicious, so I have published some comments on the issue of the appointment and installation in the deepdotmy.com product page and the YouTube page. Then I found that all these comments were deleted that I did not use any improper words. So far, all these behaviors have not received any positive response, and basically, there is no longer any reply to my email. In the meantime, I found out that they had moved the website deepdotmy.com server from Lithuania to the United States and changed the domain name suffix to deepdotmy.ru. According to my statistics, a total of 25 users have purchased their paid products from the deepdotmy.com online. Among them, the number of bitgen buyers has been the largest. A total of $2638.04. From the current evidence gathered, about 80% of the probability belongs to the fraudulent website, and it is a very high level of false hacking tool selling fraud. The fraud way they use is probably like a download link to your product after you have completed the payment, but there are missing part of the files that you have downloaded is bound to be a missing piece of code, which makes it impossible for you to compile success at all. Then when you contact them, they will charge you $50 to $100 for installation fees. Then there's an indefinite delay until you give up the idea of installation and forget about it. -------------The following are the picture evidence I've collected------------------------------------------------------------------------------------------- Web server information before and after migration https://image.ibb.co/ct3REJ/1.png https://image.ibb.co/fTL6EJ/QQ_20180723171644.png ---------------------------------------------------------------------------- their checkout btc address: https://www.blockchain.com/btc/address/1DznDKhhmWjJ8n91ZirPtV1TCZc316yN8N?filter=2&currency=USD https://image.ibb.co/m8nHod/checkout.png ----------------------------------------------------------------- The address in a fraudulent video demonstration Pay attention to this false address.

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.

Blockchain tutorial 26: Bitcoin transaction
 
21:55
This is part 26 of the Blockchain tutorial explaining how to make a bitcoin transaction. A real demonstration is given how to make a bitcoin transaction on the Bitcoin Testnet. This tutorial shows the following: - How to create multiple public and private bitcoin Testnet key pairs. - How to claim some bitcoins from a faucet and transfer it to a sender address. - How to make a bitcoin transaction by transferring all bitcoins from a sender address to receiver address. This tutorial also explains: - What UTXO (Unspent Transaction Output) is. - What a confirmation is. 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.

Just paste the sending and the receiving address, put the BTC quantity you want for the transaction, and click on "Generate Transaction" button. The link for the transaction will appear on the "Transaction data" text box. This can be used mainly to trick Satoshibox, AIOBuy and other automatic payment systems on making they think that you have paid for the product. The transaction will get max 2 confirmations. So this won't work for transactions that require more than that. The trial version allows you to make three free transactions Hope you like it!

Cancel BTC Transfer Transaction Blockchain
 
03:09
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
