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.

Bitcoin's Origins and the Genesis Blockade
 
33:50
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. This talk took place on August 6th 2018 as part of 'The Internet of Money Tour' at the Hilton Denver Inverness in Denver, Colorado: https://antonopoulos.com/event/arapahoe-libraries-talk/ If you want early-access to talks and a chance to participate in the monthly live Q&As with Andreas, become a patron: https://www.patreon.com/aantonop RELATED: Money As A System-of-Control - https://youtu.be/FyK4P7ZdOK8 Worse Than Useless: Financial Surveillance - https://youtu.be/n4F-h4xuXMk The Currency Wars and Bitcoin's Neutrality - https://youtu.be/Bu5Mtvy97-4 Measuring Success: Price or Principle - https://youtu.be/mPMsbgWl9p4 Why Open Blockchains Matter - https://youtu.be/uZPIz3ArQww Decentralised Globalisation - https://youtu.be/QoiR4aNbTOw Investing in Education instead of Speculation - https://youtu.be/6uXAbJQoZlE Beyond Price: Bitcoin's Impact on the Future - https://youtu.be/rvwVbRQ5Ysc Wallet design and mass adoption - https://youtu.be/WbZX6BDZJHc Mass adoption and peer-to-peer commerce - https://youtu.be/n9qIAEFS-Qs Price volatility and store of value - https://youtu.be/wzzZT95ijTo Why I earn bitcoin instead of buying - https://youtu.be/Ci7TyD8jETY Job opportunities with cryptocurrencies - https://youtu.be/89_p4pDlQtI Inspiring cryptocurrency projects - https://youtu.be/WW8norCKUbE From barter to abstract money - https://youtu.be/KYsppZoHguQ Crossing the chasm of theoretical vs. real need - https://youtu.be/yIR0OBEAaUE Remittances and smuggling in Venezuela - https://youtu.be/RRXecXfWARw How long until mainstream adption? - https://youtu.be/y3cKBDBabtA What is the biggest adoption hurdle? - https://youtu.be/jHgyHF3F2TI Bitcoin as everyday currency - https://youtu.be/xYvvSV4mjH0 Hyperbitcoinization - https://youtu.be/AB5MU5fXKfo Andreas M.

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 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."

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?

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 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."

Bitcoin Rig Mining - Logo 1

What is the Bitcoin Mining Block Reward? The Bitcoin block reward refers to the new bitcoins distributed by the network to miners for each successfully solved block. How is the Block Reward Determined? Satoshi Nakamoto, Bitcoin’s creator, set the block reward schedule when he created Bitcoin. It is one of Bitcoin’s central rules and cannot be changed without agreement between the entire Bitcoin network. The block reward started at 50 BTC in block #1 and halves every 210,000 blocks. This means every block up until block #210,000 rewards 50 BTC, while block 210,001 rewards 25. Since blocks are mined on average every 10 minutes, 144 blocks are mined per day on average. At 144 blocks per day, 210,000 blocks take on average four years to mine. Total circulation will be 21,000,000 coins. It’ll be distributed to network nodes when they make blocks, with the amount cut in half every 4 years. first 4 years: 10,500,000 coins next 4 years: 5,250,000 coins next 4 years: 2,625,000 coins next 4 years: 1,312,500 coins etc… - Satoshi Nakamoto Importance of the Block Reward The block reward is the only way that new bitcoins are created on the network. Satoshi explained this in an early email post in 2009: Coins have to get initially distributed somehow, and a constant rate seems like the best formula. The block reward creates an incentive for miners to add hash power to the network. The block reward is what miners try to get using their ASICs, which make up the entirety of the Bitcoin network hash rate. ASICs are expensive, and have high electricity costs. Miners are profitable when their hardware and electricity costs to mine one bitcoin are lower than the price of one bitcoin. This means miners can mine bitcoins and sell them for a profit. The more hash power a miner or mining pool has, the greater the chance is that the miner or pool has to mine a block. As miners add more hash rate, more security is provided to the network. The block reward acts as a subsidy and incentive for miners until transaction fees can pay the miners enough money to secure the network. What Happens when the Block Reward Becomes Small? As mentioned earlier, Bitcoin users must pay a fee when sending a transaction on the network. Right now, these fees are small since there aren’t many Bitcoin users. Eventually, these transactions fees will become larger and will help make up for the decreasing block reward. In a few decades when the reward gets too small, the transaction fee will become the main compensation for nodes. I’m sure that in 20 years there will either be very large transaction volume or no volume. - Satoshi Nakamoto Do Reward Halvings Affect the Bitcoin Price? It is impossible to determine whether or not block reward halvings affect Bitcoin’s price. As with any commodity, a decrease in supply paired with no change in demand generally leads to higher price. Bitcoin is unique, however, since the block reward schedule is public. All Bitcoin users and miners know the approximate date of each halving, meaning the Bitcoin price may not be affected when the halving happens. Bitcoin’s first block halving happened on November 28, 2012. The block reward dropped from 50 bitcoins per block to 12.5 per block. The price later climbed to $260 per BTC in April 2013, followed by $1,163 per BTC in November 2013. It is unclear, however, whether these price rises were directly related to the block reward halving.

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.

Blockchain 101 Ep 04 - The Birth of the first Bitcoin!
 
00:54
The Birth of the first Bitcoin! The big day came on January 4th 2009, 3 months after the publication of Bitcoin White Paper. 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!

(Audiobook) The Original Bitcoin White Paper by Satoshi Nakamoto
 
26:01
Donations greatly appreciated! Bitcoin: 1KdkeDArSd5LVaLVh9WePaHqB9yHLaKPfv I worked very hard to create this interactive audiobook format and graciously appreciate Bitcoin donations. 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.

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! Huobi Pro will post a question in our Tweet via our Twitter account (https://twitter.com/Huobi_Pro) each time we put up an episode of Blockchain 101 post on our Twitter account, we will randomly select 20 people who answered in the format [UIDxxxxxxxx, correct answer] and retweet our post will be entitled to 1 HT each.

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/Bitcoin for beginners 9: Bitcoin difficulty, target, BITS  - all you need to know
 
48:16
In this video I break the somewhat confusing and mysterious question of how exactly the block difficulty is defined, represented and updated. There is a simplification/misconception that the requirement is just to find a hash with a required number of leading zeros in hex. This is not the case, it's a little more intricate than that.... I show some examples of real blocks - in particular focusing on the genesis block, and how import it is for initializing the difficulty of mining a block. I clarify the relationship between BITS (in the block header) difficulty, and the actual 256 hash target.
