Bitcoin Q&A: Genesis block and coinbase transactions
 
05:26
How were the first bitcoins created? Who was mining in those early days? What is a coinbase transaction and how do miners integrate it within each block? Genesis block code: https://github.com/bitcoinbook/bitcoinbook/blob/4bad0fb922c26c9088402aefe95cbf4276f2e334/code/satoshi-words.cpp More on coinbase transactions: https://github.com/bitcoinbook/bitcoinbook/blob/f8b883dcd4e3d1b9adf40fed59b7e898fbd9241f/ch06.asciidoc Note: "Coinbase" transactions should not be confused with the centralised California-based exchange, Coinbase Inc. These questions are from the MOOC 9.2 session, which took place on February 23rd 2018. 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.

Bitcoin Genesis Block
 
03:33
Today we’re taking a walk down memory lane to discover just where the very first bitcoin were ‘mined’ and how it came to be. What about the time when nobody, and I mean NOBODY owned a single bitcoin? That is, no address had any Unspent Transaction Outputs because there were no transactions, no users, and most importantly no bitcoin to spend.

What is The History of Bitcoin: Super Easy Explanation
 
12:11
What is The History of Bitcoin: Super Easy Explanation - https://blockgeeks.com/ We’ll start at the very beginning by understanding the history of blockchain. The very first blockchain in the world was Bitcoin. An anonymous person or group known as Satoshi Nakamoto published a document in an online cryptography forum in November 2008 and revealed the first details of how it would work, describing it as a “peer-to-peer electronic cash system”. The whitepaper is available today at bitcoin.org/bitcoin.pdf. It allows any 2 people to pseudonymously send money to each other no matter where they are in the world. It is a borderless currency. The main benefit of Bitcoin is that it does not require any centralized authority or institution to operate. This is in contrast to today’s centralized financial systems that depend on the existence of a central bank or government to mint money. If for any reason the central authority were to shutdown, the money would become worthless. In a decentralized system like Bitcoin, there is no central authority and the system can continue to operate as long as there are members in its peer-to-peer network. The goal of the whitepaper was to describe how the different parts of the Bitcoin protocol would operate and be kept secure. A new type of database, called a blockchain, would keep track of a single history of all Bitcoin transactions and it would be maintained by everyone in the network. The database would be publicly available for anyone to view and inspect, and anyone can download a copy of the same database. This provides data redundancy and makes sure the data is never lost, but also provides a way for anyone to verify the transactions in the database themselves. A block in the database just stores a sequence of transactions, and a sequence of blocks is called a blockchain. Each block is identified by an incrementing number and a unique Sha-256 hash. The hash for a block is calculated using the transactions inside it, as well as the previous block’s hash, which forms a chain of hashes. The data in the blocks is secured using a cryptographic algorithm called proof-of-work, which also keeps all members of the network and the database in sync to prevent double-spending. In this context, preventing double-spending means preventing anyone from spending money they dont have. Proof-of-work is used to generate new blocks for the database, also known as mining, and the reward for mining a new block is given to the miner by creating new Bitcoins in the system. This is the only way new Bitcoins can be created. Anyone on the network can be a miner and a new block is mined roughly every 10 minutes, which includes the latest set of verified transactions. The first release for Bitcoin was version 0.1 written in C++ by Satoshi and published on SourceForge in January 2009 under the open-source MIT license. Anyone could download the source code and run it to join the network, also known as becoming a node in the network. This is the original version 0.1 source code written by Satoshi. We can see the hard-coded genesis block, which is the very first block in the chain. The hash for the block can be verified by using any Bitcoin blockchain explorer. Let’s copy and paste this hash into the blockchain explorer available at blockchain.info. We can see that this hash is for block number 0, and that it has only one transaction in it which is the mining reward, and the reward amount of 50 Bitcoin was given to this Bitcoin address. We can also see this 50 Bitcoin reward for the genesis block in the original source code. The genesis block is a special case needed to start the blockchain and is the only block that is hard-coded, whereas every subsequent block is calculated using proof-of-work. Satoshi’s motivation for creating Bitcoin is revealed in the piece of data he included in the genesis block: a newspaper headline from The Times that read ‘Chancellor on brink of second bailout for banks’. The date of the newspaper is proof that the genesis block was created on or after Jan 3 2009. Satoshi developed the source code mostly himself up until mid-2010, when he handed it off to the open-source community. It is now maintained under the project called Bitcoin Core. The software is currently at version 0.15.1 and is available for download at bitcoin.org. This is still the most popular Bitcoin client, and its estimated that there are over 10 thousand nodes running the Bitcoin network today using various clients. Satoshi disappeared from public view in late 2010, his identity still unknown to this day. The only way someone could prove that they are Satoshi is by using the same encryption keys used when posting the original whitepaper in the online cryptography forum.

Bitcoin's Origins and the Genesis Blockade

In this talk, Andreas recounts the origins of Bitcoin, the meaning of the message embedded forever in its genesis block, and how we figured out who the banks truly serve when there was no other choice. He also speaks about what happens when money stops working, why censorship resistance was one of Bitcoin's most valuable characteristics from the start, and what possibilities lay in store with a global, voluntary financial system.

Bitcoin Block Details
 
11:49
A look at the details of a bitcoin blockchain block 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 removes the centralized governing body thus by increasing the transparency, trust, and security and decreasing the high processing fees, high processing time. If there is no centralized governing body who manages the transaction and how we will get the trust. To find answers to these questions we see how a block chain works with bitcoin example. One of the core technologies used in blockchain is peer to peer network or decentralized network. Here every node act both as client well as server. Here the node is just a computing device. Here each node has the copy of ledger also called as distributed public ledger. Here Mary sends 500 bitcoins to Jerald. Now this transaction will be broadcasted to all the nodes in the network. These transactions will be verified by miners, Let’s take Jessie and David are the miners who verified this transaction. This transaction will be in unconfirmed state. All the unconfirmed transaction will be present in the Transaction pool. One or more transactions in transaction pool can be clubbed together to form a block. Now they will start a race to complete a complex mathematical assignment called proof of work. Now if David completes this proof of work first. This block will be verified by all the nodes in the block chain if major number of nodes (i-e) 51 percent of nodes agrees with this block then this verified block which contains the cryptographic hash of previous block, transaction details and timestamp will be added to the block chain. Now David will get 12.5 bitcoins as reward. This is called bitcoin mining. This 12.5 bitcoins are added to the total available bitcoins. By this way new bitcoins were mined. This 12.5 bitcoins are the value as of 2018. This value will be changed to 6.25 in 2020. (i-e) The Bitcoin block mining reward halves after every 210 thousand blocks, which is approximately 4 years. In the essence, Block chain can be thought as immutable, unhackable database. In the essence block chain is a distributed database that enables permanent, transparent and secure storage of data holding encrypted ledgers. This means block is a current part of block chain which records the recent transaction. Once this block is verified it will become permanent part of block chain and can’t be modified. Block chain is completely fault tolerant (i-e) is one or more node misbehaves in the decentralized network. Block chain is resilient enough to withstand even in presence of malfunctioning nodes. This is one very important feature of block chain. In block chain trust is quantifiable which is attained using game theory such as proof or work or proof or stake. We see more about this in the fourth coming videos. By design, a blockchain is resistant to modification of the data.

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?

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/Bitcoin for beginners 6: blocks and mining, content and creation of bitcoin blocks
 
46:48
In this video we introduce the basic concepts behind how new blocks are created in the Bitcoin blockchain. We start by taking another look at the blockchain.info website to see some sample blocks and then to a quick screencast explaining how new, unconfirmed transactions are collected by mining nodes and included in new transaction blocks, whose header needs to be hashed along with a random number to produce an output hash meeting a set requirement. I mention that the requirement is that the generated hash starts with a specified number of leading zeros...this is a slight (and very common) simplification, the reality is that the hash must be LESS than or equal to a specic 256 bit binary number. See here: https://youtu.be/4QxOUwG8a2Y I introduce the concepts of difficulty targets and validation of blocks

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.

After wanting to read the original Bitcoin Whitepaper, I discovered there wasn't a good audiobook version of it with graphs and formulas. So I went ahead and made it, using a slower reading speed so a viewer can try and take it all in. I have no affiliation with bitcoin.org or Satoshi Nakamoto. Download the original whitepaper here. http://bitcoin.org/bitcoin.pdf From wikipedia.... In November 2008, a paper was posted on the internet under the name Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System. This paper detailed methods of using a peer-to-peer network to generate what was described as "a system for electronic transactions without relying on trust". In January 2009, the Bitcoin network came into existence with the release of the first open source Bitcoin client and the issuance of the first bitcoins, with Satoshi Nakamoto mining the first block of bitcoins ever (known as the "genesis block"), which had a reward of 50 bitcoins. The value of the first bitcoin transactions were negotiated by individuals on the bitcointalk forums with one notable transaction involving a 10,000 BTC pizza. "Satoshi Nakamoto" is a pseudonym for the unknown person or people who designed the original Bitcoin protocol in 2008 and launched the network in 2009. Nakamoto was responsible for creating the majority of the official Bitcoin software and was active in making modifications and posting technical information on the BitcoinTalk Forum.[73] I apologize in advance for the few wording mistakes. I tried to notate most of them.

Satoshi Nakamoto, Bitcoin whitepaper author, produced the first block of Bitcoin , “The Genesis Block”, on a small server located in Helsinki, Finland. For that, Satoshi Nakamoto obtained the first 50 Bitcoins as the reward. To commemorate the birth of Bitcoin, Mr. Nakamoto put that day’s headline of The Times article about a possible bailout for banks in the UK into the first block. Mr. Nakamoto did that to authenticate the time of Bitcoin's birth. What a brilliant mind!

Bitcoin Q&A: Iterating nonces and the block reward
 
24:25
What is the nonce? Is it possible guess it on the first try? How is the nonce found in mining pools? When a miner wins the block reward, how does the block know which address to pay? When does a miner transmit a block to the network? CORRECTION: At 18:03, I said that the chances of rolling dice below nine is the same as rolling below five. This is incorrect. It is easier to roll below nine because there are more possible outcomes. These questions are from the third session of MOOC 11, which took place on February 14th 2019.

Blockchain 101 Ep 24 - How to mine Bitcoin
 
01:08
Bitcoin is produced through mining. Every 10 minutes, miners compete to solve a complex math problem. Whoever finds the answer first, mines the block, and receives Bitcoins as a block reward. In early days, mining can be done using CPUs. However, with the increasing number of miners, CPUs are no longer powerful enough to mine Bitcoins, and people turned to mining rigs. To start mining, you need to prepare mining rigs, Bitcoin address, mining software, etc. Currently, the computing power required is too high, solo miners find it hard to get a block reward. Hence, many miners join a mining pool to do it together, miners are only responsible for providing the computing power, and the mining pool processes the transactions. When the pool receives Bitcoins, it will distribute to miners based on their contributions ensuring a stable rate of return. Watch the video here!

Inside Blockchain: Will It Crash Like Bitcoin, Or Is It Revolutionary? | Think | NBC News
 
12:29
Bitcoin, Ethereum and cryptocurrency dominated headlines in 2017, before an epic crash wiped out billions of dollars in wealth. And after the bubble burst, both bitcoin and the technology powering it — blockchain — fell out of public view a bit. The cryptocurrency crash of 2018 really set the movement back in the eyes of many. But in the background, some of the biggest companies on earth started investing… heavily: Names like Wal-Mart, Anheuser-Busch, Comcast, JP Morgan, Amazon, IBM, Deloitte, EY… you name it, they started experimenting with the technology. All the while, the crypto-prophets kept the decentralized faith. So is blockchain destined to crash like Bitcoin, or will it truly change the world as its proponents claim? In Think Again episode 3, NBC’s Andrew Stern takes us on a journey from Brooklyn to North Carolina to Texas and back again, all to figure out whether blockchain is really a breakthrough... or bogus. You’ll learn the basics of blockchain, what the real-world applications could be, and why companies are so bullish on the technology. You’ll also hear from perhaps the most infamous blockchain skeptic in the cryptocurrency world. » Subscribe to NBC News: http://nbcnews.to/SubscribeToNBC » Watch more NBC video: http://bit.ly/MoreNBCNews NBC News is a leading source of global news and information.
