The Bitcoin Blockchain Explained
 
03:41
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

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?

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 and cryptocurrency mining explained
 
07:46
https://www.udemy.com/blockchain-for-business-the-new-industrial-revolution/?couponCode=YOUTUBE Bitcoin and cryptocurrency mining explained with the the Byzantine Generals Problem. The Byzantine Generals problem was first introduced in a computer science paper published in 1982. The problem discussed in the paper is that reliable computer systems must be able to function effectively in the presence of faulty components that may send conflicting information to different parts of the system. This issue is even more acute when we talk about decentralized computer networks. Imagine the following thought experiment: The Byzantine army has surrounded an enemy city. The army is organized into several units. Each unit is commanded by a general and they all need to come up with a coordinated plan of action. However, they are located away from each other and the only means to communicate among themselves is via messages. To make things more complicated, one or more of the generals are possibly traitors. The presence of disloyal generals means that misleading messages could be sent aiming to disrupt any coordinated plan of action, be it attack or retreat. To find a successful solution to this conundrum, the Byzantine army needs to find its path to coordinated action, one way or another. To achieve this, the Byzantine army needs an algorithm that works effectively towards a coordinated outcome where the loyal generals follow it and the traitors don’t. Now that you are familiar with the problem, let’s see its solution. It is called the Byzantine Fault Tolerance algorithm. Over the years, there have been several proposed theoretical solutions involving game theory and math. The first practical implementation of Byzantine Fault Tolerance algorithm came with the Bitcoin’s Proof-of-Work. In this case the “generals” are nodes on the Bitcoin network, also known as “miners”. A network node is a connection point that can receive, create, store and send data across a network. In other words, nodes are the connected dots that make up a network. To simplify, think of it in the following way. In the image we traditionally use to depict a blockchain, every single computer is a separate node. They are all connected and can receive, create, store, and send data to each other. In the context of the Byzantine Fault Tolerance algorithm, the important concept to grasp is that these mining nodes start from the assumption that nobody else on the network can be trusted. Proof-of-Work secures network consensus even in the presence of non-compliant nodes. That is, even if there are some Byzantine generals who are not acting in the army’s best interest, coordinated action can still be achieved. Let’s see how this mechanism works in Bitcoin. As we all know by now, Bitcoin is a peer-to-peer network where all activities are done by its users through appropriate software and hardware. These activities include making transactions, receiving transactions, and verifying and transmitting transactions. Now, this is where we need to introduce the concept of “mining”, which many of you have probably heard. Mining is an activity, carried out by network participants, which involves Proof-of-Work and results in generating new coins as a reward for the miner who successfully did this Proof-of-Work first for each new block.

Note1 - At 6:46 when Chris is drawing the Merkle Tree, C would actually be duplicated and hashed with itself not with B. So you would get H(C - C) instead of H(B - C). Note2 - At minute 17, Christopher mentioned the mining reward halving at 21,000 bitcoins but meant 210,000 blocks.

Developing Blockchain Software
 
59:37
This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges. Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns. C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do.

After incubating through millions of Bitcoin transactions and a host of developer projects, it is now on the tips of tongues of CEOs and CTOs, startup entrepreneurs, and even governance activists. Though these stakeholders are beginning to understand the disruptive potential of blockchain technology and are experimenting with its most promising applications, few have asked a more fundamental question: What will a world driven by blockchains look like a decade from now?

Michael Goldstein Explains How The Bitcoin Block Chain Enables Smart Property
 
35:06
In our previous video Michael Goldstein explained how the Bitcoin network can be used for more functions on top of the currency transfers. This functionality is called smart contracts and it consists of adding to each Bitcoin transaction some code script to "condition" transfers to external events happening as a requisite to the transfer. For example "time locking" can be used to determine a future moment in time to execute the transfer, 3 signatures can be established to have third parties verify transactions, or assurance contracts can be determined to enable funding for special projects. In this interview Michael explains another functionatlity that can be integrated to Bitcoin transactions: Smart Property. He talked about: - How the block chain, ledger, mining, proof-of-work, and network consensus work. - What is smart property. - Real life examples. - Public and private key management. - How property can be registered, transferred, and used on the block chain.
