Blockchain tutorial 22: Double spending, third party
This is part 22 of the Blockchain tutorial explaining what double spending is. The ecash system conceived by David Chaum is used as an example why third parties are used. In this tutorial several examples are given why we should not use third parties. 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.

What is 51% attack or double spend attack? Can Bitcoin be hacked?
Following is a book that literally changed my life. It is called "7 Habits of highly afffective people". Following is a link for this book https://amzn.to/2KDzV9h What is 51% attack or double spend attack? Can Bitcoin be hacked? In this video I will be explaining about 51% attack or double spend attack. This video will answer if a block chain can be hacked or not? Below is the narration that I used in this video. A wants to buy a car from B, and agreed to accept bitcoins for the car. Now A wants to send 5 bitcoin to B to buy the car A sends 5 bitcoin to B by entering receiver’s address, then this transaction is put into pool of unconfirmed transactions. Miners who have computational power select these transactions(let’s say the above transaction is picked) to make them into a block of transactions To add this block of transactions to the blockchain, they need to find the solution to a very difficult mathematical problem. We all know that bitcoin follows proof of work consensus mechanism. Proof of work is to solve a very difficult mathematical problem and rest of miners accept this work. The more computational power a miner has, the better his chances to find a solution compared to other miners As soon as a miner has found a solution, he will broadcast it to the other miners and they will only accept it if all transactions inside that block are valid according to the existing record of transactions on the blockchain. There is a possibility that the miner(let us suppose A) who found the solution may not send it to other miners in the network to agree on consensus and rather can create a fork of the existing blockchain. This leads to two versions of the blockchain One is the right version which is being followed by all miners and the other one is followed by corrupted miner The corrupted miner goes on creating blocks on his version of that blockchain and is not broadcasting it to the rest of the network. The truthful miners do not choose the corrupted chain as it hasn’t been broadcasted to them In the truthful version of blockchain, the transaction from A to B is complete and B receives the 5 bitcoins sent by A. In return A receives his luxurious car. Meanwhile, A does not include his transaction in the corrupted version of his blockchain. Now he still has his 5 bitcoins in this version of blockchain Now he is trying to solve the mathematical problem himself and creating blocks without broadcasting them to the entire network but adding them to the corrupted chain he has started. Now blocks are being added to both the chains, in one case the block being verified by all miners and other case block being verified by only A This is where the trouble starts. The blockchain follows a model of democratic governance that is by following the longest chain. It takes this approach because it is obvious that majority adds blocks to their version of the blockchain faster than the rest of the network. So longer the chain, blockchain takes it as the truthful version of the chain There is a race between two chains one truthful and other untruthful chain A will now try to add blocks to his isolated blockchain faster than the other miners add blocks to truthful blockchain. As soon as he reaches to the position where A’s version of blockchain is longer than truthful blockchain, he broadcasts it to the rest of the network The rest of the network will now detect that A’s version of the blockchain is actually longer than the one they were working on, and they are forced to move to this chain following the blockchain governance A’s corrupted blockchain is now considered the truthful blockchain, and all transactions that are not included on this chain will be reversed immediately. A not only has spent his Bitcoins on buying a car from B, but also is now once again in control of those Bitcoins. A can spend them again This is a double-spend attack. It is commonly referred to as a 51% attack because the malicious miner will require more hashing power than the rest of the network combined (thus 51% of the hashing power) in order to add blocks to his version of the blockchain faster, eventually allowing him to build a longer chain.

What is DOUBLE-SPENDING? What does DOUBLE-SPENDING mean? DOUBLE-SPENDING meaning & explanation
What is DOUBLE-SPENDING? What does DOUBLE-SPENDING mean? DOUBLE-SPENDING meaning - DOUBLE-SPENDING definition - DOUBLE-SPENDING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Double-spending is an error in a digital cash scheme in which the same single digital token is spent twice or more. This is possible because a digital token consists of a digital file that can be duplicated or falsified.. As with counterfeit money, such double-spending is Inflation by creating, during the duplication or falsification of the digital file, a new amount of currency that hadn't existed prior to that time. This devalues the currency relative to other monetary units, and diminishes user trust as well as the circulation and retention of the currency. Fundamental cryptographic techniques to prevent double-spending while preserving anonymity in a transaction are blind signatures and particularly in offline systems, secret splitting. The prevention of double-spending has taken two general forms: centralized and decentralized. This is usually implemented using an on-line central trusted third party that can verify whether a token has been spent. This normally represents a single point of failure from both availability and trust viewpoints. By 2007, a number of distributed systems for double-spending prevention had been proposed. The cryptocurrency Bitcoin implemented a solution in early 2009. It uses a scheme called proof-of-work, to avoid the need for a trusted third party to timestamp transactions. These timestamps are recorded in its public ledger called the blockchain. This avoids anyone double-spending the currency.

Bitcoin Q&A: Miners, pools, and consensus
How many miners and/or pools are there? Can the distribution of miners be determined? Would mining pools be incentivised to merge? Is miner collusion through 51% attacks a present threat? Could they double-spend their coins? How are they impacted by replace-by-fee (RBF)? These questions are from the MOOC sessions 7.2, 8.2, and 9.2 covering the Byzantine Generals' Problem, which took place on February 26th 2017, September 15th 2017, and February 23rd 2018 respectively. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles.
