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

Blockchain tutorial 24: Blockchain and miners
 
07:34
This is part 24 of the Blockchain tutorial explaining what a Blockchain is and what miners are. This tutorial explains the following: - what the blocks are in the blockchain - what data does a block contains - what a block number and block height is - what a genesis block is - what a main chain, side fork or orphaned forks are - what miners are and their purpose - what a coinbase transaction is and how Bitcoins are created - there will be maximum 21 million Bitcoins - what a block reward is - what block reward halving is - what a hash puzzle 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.

Why Can't We Have Faster Bitcoin Blocks?
 
02:40
The bitcoin network is limited in capacity by the timing of its block mining. What if the mining were upgraded to happen more quickly? This simple change would bring some significant improvements, but the world of cryptocurrency is not always what it seems. In this video, we discuss a couple of potential benefits, and then why those benefits maybe aren't such a big deal after all, and we'll finish out with why this upgrade will probably never happen anyway. --- This eposide is sponsored by KeepKey: The Simple Bitcoin Hardware Wallet.

Monero Blocks Bitmain’s Attempts to Monopolize its Mining With ASIC
 
01:13
https://cryptocomes.com/monero-blocks-bitmains-attempts-to-monopolize-its-mining-with-asic After threatening to combat Bitmain’s latest Monero ASIC miner, Monero has gone ahead with an update which will maintain the ASIC resistance. In a battle of cat and mouse, Monero has fired the latest shot at Bitmain after the ASIC mining hardware producer announced it would be releasing their new ASIC-powered Antminer X3 designed to mine Monero. Monero has gone through with threats they laid out that were designed to prevent the new device from being effective. The new Monero update, called Lithium Luna, is scheduled for April and the release document for the update states that it “slightly changes the proof-of-work algorithm to prevent DoS attacks by ASICs.” Following through When the Antminer X3 was added to the Bitmain site, there was an immediate reaction from the author of the Lithium Luna post, Monero lead Dev, Riccardo Spagni. He took to Twitter stating that “this WILL NOT work on Monero.” It had always been their mandate to fight against any sort of ASIC take over when it came to mining, and back in February, in their blog, they posted as such. Essentially, it stated that they would actively counter any sort of ASIC mining equipment, and have now followed through with this latest update. Steadfast in their charge Monero is a cryptocurrency that prides itself on their privacy as well as their ASIC resistance, so much so that despite there being a potential for security risks, the update will go ahead in order to stop Bitmain’s mining influence.

Bitcoin Q&A: What happens to transaction fees when the block reward is zero?
 
04:28
Keywords/phrases: Based on the incentives in the network, what happens to fees when the reward for generating new blocks goes to zero? Will miners keep mining? Will the network fees be reasonable? This will gradually happen between now and 2141. Presumable the reliance on the block reward drops while the number of transactions rises. Fees will go up not because it's getting more and more expensive but because you have more and more transactions paying the same fee or less. We know this is going to happen just as we knew the Halvening was going to happen, because bitcoin is a deterministic currency. We don't have to wait for the spokesperson from the Federal Reserve to come out and tell us what our interest rate is. We're getting better at optimisation. If we introduce all the optimisation and scaling things, we can do more than Visa - cheaper. We will manage capacity in a way that isn't fatal, failing to scale (gracefully) for 25 years.

Bitcoin Miner - What is a Bitcoin Miner? Win FREE Bitcoins here: http://win-free-bitcoins.com ... Today !! https://wiki.archlinux.org/index.php/Bitcoin Bitcoin is a decentralized P2P electronic cash system without a central server or trusted parties. Users hold the cryptographic keys to their own money and make transactions directly with each other, with the help of the network to check for double-spending. Bitcoins, usually denoted by BTC (i.e. '144 BTC'), can also be exchanged for traditional currencies like US dollars. The Bitcoin network runs on peer-to-peer networking, digital signatures and cryptographic proof to make and verify transactions. Nodes broadcast transactions to the network, which records them in a public record of all transactions, called the block chain. A block is a record of some or all of the most recent Bitcoin transactions that have not yet been recorded in any prior blocks. In order to preserve the integrity of the block chain, each block in the chain confirms the integrity of the previous one, all the way back to the first one, using hashing. New bitcoins are generated by the network through the process of mining. Mining involves inserting a new block into the current block chain, this is difficult because it requires generating a valid hash (in this case a large integer). A variation in difficulty is achieved by requiring that this integer is below a certain threshold - the data in the block is perturbed by a nonce value, until the data in the block hashes to produce an integer below the threshold - which takes a lot of processing power. The threshold is set by the number of people currently mining for bitcoins so as to achieve a general speed of about 1 block every 10 minutes.

Mining Bitcoin with pencil and paper

Bitcoins are mined using a cryptographic algorithm called SHA-256. This algorithm is simple enough to be done with pencil and paper, as I show in this video. Not surprisingly, this is a thoroughly impractical way to mine. One round of the algorithm takes 16 minutes, 45 seconds which works out to a hash rate of 0.67 hashes per day.

What is Bitcoin mining? - GMO INTERNET
 
01:34
https://mining.gmo.jp/ Bitcon is built on blockchain technology that regularly adds all transaction records to blockchain, which is a chain of blocks saved on the network. If transaction data of Bitcoin, which is exchanged all over the world, is transmitted to the network, miners worldwide will compete to generate a block of transaction data of a given time period. The exact block needs to be generated while recording to the blockchain and ensuring the integrity of the new transaction data. The work involves intensive computation. If a given miner succeeds in generating the block first, and the block is approved and added to blockchain, Bitcoin is issued as a reward to the miner. Data fraud is prevented and Bitcoin is kept integrated and safe through the above process ("mining").

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.

Consensus and Mining on the Blockchain
 
08:03
Consensus and Mining on the Blockchain - https://blockgeeks.com/ What is consensus on the blockchain? Consensus basically means that all nodes in a decentralized network must come to an agreement on what is the truth. For bitcoin, all nodes must agree on the transaction history. In a centralized system, all the participants trust that the authority will behave honestly and share the truth with the rest of the members. Since only the trusted party has the power to modify the data, it is straightforward to achieve consensus. Everyone simply accepts and believes what the central authority says. For example, you simply trust your bank will put the correct balance for your account whenever you send and receive money. However, in a decentralized network, there is no central authority and each node does not trust any other nodes. The challenge is how can all the nodes agree on what is the correct state of the shared data? In other words, how can they all achieve consensus with mutual distrust? In computer science, this is known as the Byzantine Generals’ problem, which was originally presented in 1982. The Byzantine Generals’ problem is a description of consensus problems in computer networks. More specifically, how can distributed computer systems handle malfunctioning parts that give conflicting information to different parts of the system? This problem is abstractly described as a group of generals of the Byzantine army camped with their troops surrounding an enemy city. The generals must agree upon a common battle plan and they can only communicate with each other using messengers. However, one or more of the generals may be traitors who will try to confuse the others. The problem is to find an algorithm that ensures the loyal generals will all reach an agreement on the battle plan regardless of what the traitors do. In the case of bitcoin, each general could be thought of as a node in the network and all the honest nodes must agree on what is the true history of transactions. A malicious node can send conflicting transactions to different parts of the network. For example, Bob is a traitor and he sends a transaction stating he sent 10 bitcoins to Alice to one part of the network while sending another transaction stating he sent 10 bitcoins to Carroll to other parts of the network. Let’s assume that Bob only has 10 bitcoins in total, so he is trying to double spend his bitcoins. So what algorithm can be used in the bitcoin network to ensure all the honest nodes recognize Bob sent 10 bitcoins to Alice but reject that he sent 10 bitcoins to Carroll? Bitcoin uses the proof-of-work (PoW) algorithm to ensure all the honest nodes reach a consensus on the true history of transactions. The PoW algorithm concept was first developed in the early 90s to prevent email spamming. It required computers that want to send an email to do some computation work which took some time to complete before sending out the email. This reduced the amount of spam an email server could get in a given period of time. In bitcoin, PoW is used to govern the mechanics of how a new block is added to the blockchain. In the previous lesson, we learned that blockchain is append-only and once a block is added, it cannot be modified. Therefore, we need to ensure that all the honest nodes in the system will add the exact same block to their local copy of the blockchain to achieve consensus. So how does PoW achieve this? First, let’s imagine that all the nodes in the network are allowed to create a new block at anytime instantly. If this were the case, the network would get flooded with too many new blocks, and no one would be able to agree on which of the new blocks should be added to the blockchain. However, in reality, in order for a node to create a new block and broadcast that to the other nodes, it must do some computation work. The computation work is quite intensive and for bitcoin it takes roughly 10 minutes on average for any node to complete. Once a node completes this work, it broadcasts the block to other nodes who verify it. Therefore, all the nodes in the network that want to create a new block must race against each other to be the first one to complete this computation and broadcast their block. This way all the other honest nodes will receive the new block and verify that the proof of work was valid and the transactions inside the block are also correct and then add the block to their local copy of the blockchain.

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. Bitcoin mining refers to the process through which new Bitcoins are created and given to computers helping to maintain the network. The computers involved in Bitcoin mining are in a sort of computational race to process new transactions coming onto the network. Thanks for watching this Video, Please Like and Share.

Blockchain 101 Ep 11 - Why haven't we finished mining Bitcoins
 
01:11
For sustainability, the Bitcoin network adjusts its mining difficulty. Every 10 minutes, miners compete to solve a complex math problem to create the next block for Bitcoin rewards. If the processing power of the Bitcoin network keeps increasing, we will finish mining all Bitcoins in no time. To maintain the rate of new block generation at once every 10 minutes, Satoshi Nakamoto has designed the system to adjust the mining difficulty every two weeks, every 2016 blocks. As such, the adjusted difficulty will keep the new block generation rate at the expected time frame of 10 minutes. Currently, the difficulty is set at 480PH/s, about 68 billion times harder than mining the genesis block. That means, based on the current computing power, all miners need to perform 300 sextillion(3*10^23)hashes to find the right answer to mine the new block. Watch the video here!

BitClub functions two mining places using the fastest growing facility located within Iceland. This particular facility is available for the public who meet certain credentials for visitation privileges. The actual mining pool is available to public to ensure anyone who want to lead hashing power can certainly achieve this. Everybody can subscribe and become part of it if you meet the criteria They buy all mining equipment which enables BitClub to keep full control and just sell the hardware within the secondary market when it is getting close to the end of it's peak period. The providers swap these away with regard to newer and even more powerful devices. When they sell a older batch of apparatus our individuals are able to think about having the miner after they choose. Each bit club associate assists guide on the procedures from the mining pool simply by "chipping in" Bitcoin to pay this. This repurchase strategy is what permits us to continuously increase and buying more mining computer hardware. Bitcoin How Many Blocks-- Bitcoin is genuinely a global currency that employs an open ledger technique to track record trades being sent in someone to another. Doing this happens without central lender in the centre which is not controlled by government, controlling system, individual company, or particular person. All transactions will be entirely transparent plus a large number of replicates in the ledger are actually saved around a distributed network of computers without any anchorman of failure.

Report Links 74% of Bitcoin Mining to China, Sees Threat on Horizon

China has banned bitcoin yet it's nation has a high concentration of mining machines. Did this happen by accident? Link to story and other stories mentioned: https://bitcoinmagazine.com/articles/report-links-74-bitcoin-mining-china-sees-threat-network/ https://www.theboltonnews.co.uk/news/national/16954295.chinese-destroyer-came-dangerously-close-to-us-navy-ship/ https://gazette.com/premium/colorado-springs-on-front-lines-of-cyber-cold-war-with/article_ba27558c-cd84-11e8-b6c0-67dd2827470a.html https://www.express.co.uk/news/world/1004663/world-war-3-china-training-airstrikes-american-targets-pacific-south-china-seas-taiwan Donate: http://paypal.me/Ansary Monthly: http://www.patreon.com/alexansary and also options at http://www.alexansary.tv/donate Email: [email protected] Newsletter: http://www.alexansary.tv/otbnews.html From the article: Bitcoin, the world’s most sought-after cryptocurrency, could be at the wish and whim of Asia’s economic giant. A recent study titled “The Looming Threat of China: An Analysis of Chinese Influence on Bitcoin,” jointly researched by Princeton University and Florida International University researchers, suggests China’s mining scene has an overwhelming influence over Bitcoin, something that could invite network manipulation. China, which the researchers refer to as the “most powerful adversary to Bitcoin,” has long been known as the country with the largest numbers of miners in the world and the home to Bitmain — the company responsible for mining roughly half the world’s bitcoins. Bitcoin's network is largely dependent on miners, who use a vast amount of computing power (hash rate) to verify transactions, find blocks to continue the network’s ledger and mint new bitcoin — and 74 percent of that computing power currently resides in China, according to the study. The Bitcoin community is privy to this worrisome trend and has been wary of a potential attack that could be spurred by external factors. Controlling 51 percent of the network’s hash rate opens the threat of a 51% attack, a scenario where miners can modify transactions on the ledger for their own economic gain. According to the report, the Chinese government is keeping its eye on all of the Bitcoin-related activity going on in its domain, and, given the concentration of miners in the area, it may have the potential to disrupt the Bitcoin network. It claims that the government has made well-calculated efforts to reduce the speed of Bitcoin’s network. The researchers made references to China’s Great Firewall and the Great Cannon as the primary tools used to modify and keep track of internet traffic into the country in its bid to hinder the network. While expatiating on China’s technical ability to weaken bitcoin, the paper gave insight on how the Great Firewall was used to incentivize miners to mine “empty blocks” — a possibility since put to rest with the recent Bitcoin software upgrade. The study explored other ways within China’s disposal to weaken the cryptocurrency, among which are a series of regulatory and technical actions. A vivid regulatory option would involve IP surveillance targeted at Bitcoin users to prevent them “from committing transactions to the blockchain.” Another option at the country's disposal is the deanonymization of bitcoin users, linking them to real-world entities and disrupting the activities of competing mining pools to “consolidate their control” over Bitcoin.
