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.

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?

Forget the currency; it’s the protocol behind it that matters. Blockchains will mutate and take over everything we do on the Web. Trusting strangers with your digital information may sound silly, but it’s actually a revolution in distributed computing. And one day, systems like Bitcoin could be the future of all secure digital transactions. Read more: http://bit.ly/29jiJ3B

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.

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."

http://www.Blockchain.ie - Irelands Blockchain Explorer Blockchain Ireland - n the context of its first digital currency, Bitcoin, a “Blockchain is a digital ledger that records every Bitcoin transaction that has ever occurred. It is protected by cryptography so powerful that breaking it is typically dismissed as “impossible”. More importantly, though, the blockchain resides not in a single server, but across a distributed network of computers. Accordingly, whenever new transactions occur, the blockchain is authenticated across this distributed network, then the transaction is included as a new “block” on the chain.” Bitcoin, in its simplest form is a digital currency. The Blockchain system itself is what allows people worldwide to transfer money quickly and at virtually no cost. Blockchain.ie are members & partly funded by the official Irish Bitcoin Foundation (http://www.Bitcoinirl.ie) & the Blockchain Standards Authority of Ireland (http://www.BSAI.ie) We recognise that decentralised and distributed digital currency and payment systems in which payments are processed and secured by advanced cryptography and distributed computing power is the way of the future. Our team, in the Fintech capital of the world – Dublin, Ireland, have been chosen to bring this futurism of the Blockchain, Bitcoin to this planet we call earth. Blockchain technology continues to redefine the global financial sector everyday. Futurism as its core – See what it can do for you. http://www.www.Blockchain.ie

How Bitcoin Works in 5 Minutes. (Technical)
 
05:26
How does Bitcoin work? This is a question that often causes confusion. Here's a quick explanation! The basics for a new user As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once. Bitcoin Balances - block chain The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography. Transactions - private keys A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining. Processing - mining Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.
