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?

Understand the Blockchain in Two Minutes
 
02:26
Over the past decade, an alternative digital paradigm has slowly been taking shape at the edges of the internet. This new paradigm is the blockchain. 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?

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.

Blockchain 101 Ep 79 - What is Ethereum (Special extended version)
 
03:12
Ethereum, is also known as ETH. At the end of 2013, Vitalik issued the White Paper for Ethereum and began presale in July 2014. At that time, this move was known as "token crowdfunding" by the crypto community. In the presale period of 42 days, through the sale of 60102216 Ether, Ethereum's team managed to raise over 30,000 Bitcoins Also, early stage supporters and developers involved prior to the presale were allocated 9.9% of the total amount of issued Ether. Ethereum had a total of over 72 million tokens at during its launch. When presale of Ether ended, the Proof of Work (PoW) consensus model was adopted and every year 26% of the total issued tokens then were rewarded to miners. October October 2014, Ethereum reduced its block time from 60 seconds to 12 seconds. Currently, the block time is at 15 seconds and block rewards at 5 Ether. Although both Bitcoin and Ethereum utilize Proof of Work (PoW) for mining, the way they generate blocks differs. Due to Ethereum’s shortened block time, it is more prone to forming orphaned blocks. Orphaned blocks are blocks that are not on the longest running chain. Orphaned blocks on Bitcoin do not receive any block rewards. However, for Ethereum, orphaned blocks can be utilized and they’re known as "uncle blocks". Their block data are also recorded in the chain. Unlike Bitcoin, Ethereum's uncle block gives out rewards too. The maximum reward for each uncle block is 4.375 Ethereum. Ethereum is a codable, turing complete blockchain development platform, equivalent to a global decentralized computer. In a programming system, there are normally virtual machines to support compilation and execution. JAVA has JVM. In Ethereum, there is the Ethereum Virtual Machine, EVM, which carries out increasingly complex coding algorithms. Developers may use JavaScript or Python and other programming language to create applications on Ethereum. Through the Ethereum Virtual Machine, one can easily issue digital asset, write a smart contract, build and operate a decentralized application, establish a decentralized, autonomous organization etc. ETH is also known as “gas” within Ethereum. Different from other cryptocurrencies, In addition to fund transfers, Ethereum can also be used for payment of smart contract fees. In order to prevent the proliferation of junk contracts and applications on Ethereum, payment of smart contract fees in ETH is required for developing and execution of smart contracts. For example, to transfer your newly created digital asset on Ethereum, the fee to be paid is in ETH, not with your newly created tokens.

WHAT IS BLOCKCHAIN?
 
02:31
A blockchain is a digitized, decentralized, public ledger of all cryptocurrency transactions. Constantly growing as ‘completed’ blocks (the most recent transactions) are recorded and added to it in chronological order, it allows market participants to keep track of digital currency transactions without central record-keeping. Each node (a computer connected to the network) gets a copy of the blockchain, which is downloaded automatically. Originally developed as the accounting method for the virtual currency Bitcoin, blockchains – which use what's known as distributed ledger technology (DLT) – are appearing in a variety of commercial applications today. Currently, the technology is primarily used to verify transactions, within digital currencies though it is possible to digitize, code and insert practically any document into the blockchain. Doing so creates an indelible record that cannot be changed; furthermore, the record’s authenticity can be verified by the entire community using the blockchain instead of a single centralized authority. A block is the ‘current’ part of a blockchain, which records some or all of the recent transactions. Once completed, a block goes into the blockchain as a permanent database. Each time a block gets completed, a new one is generated. There is a countless number of such blocks in the blockchain, connected to each other (like links in a chain) in proper linear, chronological order. Every block contains a hash of the previous block. The blockchain has complete information about different user addresses and their balances right from the genesis block to the most recently completed block. The blockchain was designed so these transactions are immutable, meaning they cannot be deleted. The blocks are added through cryptography, ensuring that they remain meddle-proof: The data can be distributed, but not copied. However, the ever-growing size of the blockchain is considered by some to be a problem, creating issues of storage and synchronization.

Blockchain scaling problem And ICO Doom!

Blockchain scaling problem And ICO Doom! You'll receive $10 in free bitcoin by signing up with this link http://bit.ly/2oesV41 Bitcoin & Ethereum Storage Wallet: http://bit.ly/2o7BmgW Exchange cryptocurrency at the best rate: http://bit.ly/2yOUg1U Consulting with me: Book Here https://clarity.fm/ameerrosic Blockgeeks YouTube Channel https://www.youtube.com/c/BlockGeeks All I want to do is, talk about the absurdity and FOMO economics of the ICO space and why Blockchain tech is not yet ready for the promises it delivers. On that note, if you missed my last post about “why 99% of ICO will Fail” I recommend that you read that first The reality of today is. Blockchain promises this. ...But delivers that. Too many people are feeding the hype and promise of this amazing tech way before it has time to mature. So I just want you to read this point to understand that we are a long way before we can scale and deliver on the promise. Big Elephant in the room is scalability Blockchain consensus protocols like Bitcoin, Ethereum, Tendermint make a tradeoff between low transaction output and being an open source decentralized system vs a Centralized system. As the size of the blockchain grows, the requirements for storage, bandwidth, and compute power, goes up and up and up. Why does this cause a problem? Because every fully participating node in the network must process every transaction. Meaning each node, for the most part, needs to download and update the whole blockchain. Remember that blockchains have one inherent critically important characteristic — “decentralization” — which means that every single node on the network processes every transaction and maintains a copy of the entire state. In order to scale, blockchain protocols must figure out a mechanism to limit the number of participating nodes needed to validate each transaction, without losing the network’s trust I will give you an example with Ethereum This is via Fred Ershan “At the moment, Ethereum can handle about 13 transactions per second, which cuts in half to about 7 transactions per second for tokens (4.7m gas limit, 21k avg gas price for standard txn = ~220 standard txns every block, current avg block time 17s = 13 txns/sec, gas requirement roughly doubles for token transactions). And this doesn’t include more expensive smart contract execution. By this estimate we’re roughly 250x off being able to run a 10m user app and 25,000x off being able to run Facebook on chain. And since these systems are open rather than proprietary, we’ll see applications bigger than Facebook. This estimate isn’t perfect because the dApp stack functions differently in places than the current Web 2.0 stack. But I believe it’s in the right ballpark. This is why I believe scalability will be the primary bottleneck for the industry for the foreseeable future.” Where do we go from here? Simple answer. We need to be working more on protocol layers for scaling for both scaling transactions and also scaling security protocols. Some that come to mind are. Plasma Cosmos Lighting network Ethereum Casper - POS Etc… All of these are still under development and it will take years before we see the speed and security that we need in order to sustain the hype that blockchain promises. And this why I stress the education part on ICO's. It's scary when you see all of these ICO's raise millions that are building on top of protocols that won't be ready for years. Bottom line. We have a long way to go!

What the Future Holds for New Blockchain ETF from First Block Capital
 
02:28
It’s Invest Diva's Kiana Danial https://www.investdiva.com/ with NewsBTC and here is your cryptocurrency update. We’ve been patiently waiting for the SEC to make a decision on the first-ever Bitcoin ETF. But for those who are passionate about the blockchain industry, and want to get indirect exposure, there is a new blockchain ETF that could be coming out next month. Issued by the Vancouver-based First Block Capital, it’s called the FBC Digital Ledger Technology Adopters ETF. Sure, there are already a couple of ETFs out there who focus on companies with blockchain in mind, including the Amplify Transformational Data Sharing ETF and the Reality Shares Nasdaq NexGen Economy ETF. But First Block is aiming to make this one more accessible by reducing the premium fees, and also by focusing beyond just tech companies like Nvidia. There are so many public retail companies who are investing heavily in the blockchain technology, including Overstock and Walmart. While we don’t know exactly what this new ETF around the block will be holding in its basket, according to the company’s COO, Bill Stormont, it will at least have names like Walmart and Maersk. The company is in the final stages of getting regulatory approval, and its shares are expected to start trading on Canada’s Aequitas NEO Exchange in September. Now I want to hear from you. Would you rather invest in a blockchain ETF, or invest directly in cryptocurrencies? Let me know in the comments. Thanks for watching, invest responsibly, and I’ll see you with more updates next time.

What is a Smart Contract? A Beginner’s Guide

Smart contracts help you exchange money, property, shares, or anything of value in a transparent, conflict-free way, while avoiding the services of a middleman. The best way to describe smart contracts is to compare the technology to a vending machine. Ordinarily, you would go to a lawyer or a notary, pay them, and wait while you get the document. With smart contracts, you simply drop a bitcoin into the vending machine (i.e. ledger), and your escrow, driver’s license, or whatever drops into your account. More so, smart contracts not only define the rules and penalties around an agreement in the same way that a traditional contract does, but also automatically enforce those obligations. Example Suppose you rent an apartment from me. You can do this through the blockchain by paying in cryptocurrency. You get a receipt which is held in our virtual contract; I give you the digital entry key which comes to you by a specified date. If the key doesn’t come on time, the blockchain releases a refund. If I send the key before the rental date, the function holds it releasing both the fee and key to you and me respectively when the date arrives. The system works on the If-Then premise and is witnessed by hundreds of people, so you can expect a faultless delivery. If I give you the key, I’m sure to be paid. If you send a certain amount in bitcoins, you receive the key. The document is automatically cancelled after the time, and the code cannot be interfered by either of us without the other knowing, since all participants are simultaneously alerted. You can use smart contracts for all sort of situations that range from financial derivatives to insurance premiums, breach contracts, property law, credit enforcement, financial services, legal processes and crowd funding agreements.

Crypto Currency | Blockchain | Bitcoins
 
05:28
A cryptocurrency (or crypto currency) is digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets. Cryptocurrency is a kind of digital currency, virtual currency or alternative currency. Cryptocurrencies use decentralized control[4] as opposed to centralized electronic money and central banking systems.The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database. Bitcoin, first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency.Since then, over 4,000 altcoin (alternative coin) variants of bitcoin have been created. According to Jan Lansky, a cryptocurrency is a system that meets six conditions: The system does not require a central authority, distributed achieve consensus on its state [sic]. The system keeps an overview of cryptocurrency units and their ownership. The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units. Ownership of cryptocurrency units can be proved exclusively cryptographically. The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units. If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them. Altcoin The term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies,"while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin.Aaron Hankins of the MarketWatch refers to any cryptocurrency other than bitcoin as altcoins. Blockchain Main article: Blockchain The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.Each block typically contains a hash pointer as a link to a previous block,a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain. It solves the double spending problem without the need of a trusted authority or central server. The block time is the average time it takes for the network to generate one extra block in the blockchain.Some blockchains create a new block as frequently as every five seconds.By the time of block completion, the included data becomes verifiable. This is practically when the money transaction takes place, so a shorter block time means faster transactions.[citation needed] Timestamping Cryptocurrencies use various timestamping schemes to avoid the need for a trusted third party to timestamp transactions added to the blockchain ledger. Proof-of-work schemes The first timestamping scheme invented was the proof-of-work scheme. The most widely used proof-of-work schemes are based on SHA-256 and scrypt. The latter now dominates over the world of cryptocurrencies, with at least 480 confirmed implementations.

Blockchain is extremely interesting as used as a currency, but what does it look like in everyday use? How will the world change if this is adopted? Chelsea Rustrum explores shared ownership and value distribution through the lens of the sharing economy and blockchain technology. She’s the author of It’s a Shareable Life, the founder of Blockchain for Good, a social and educational series, and the co-founder of Blox 7, a new economy storytelling agency. Chelsea grew up a teenage entrepreneur building businesses online from middle school onward.

Blockchain Consensus Algorithms and Artificial Intelligence
 
31:17
Is blockchain + AI a winning combo? Yes! They are complementary technologies, and knowing how both work will make you a much more powerful developer. Artificial Intelligence can use the power of the blockchain to audit data, add incentives to its goals, and even create new types of meritocratic organizations. In this video, i'll talk about how they can both work together, code out the proof of work algorithm in python, then talk about a few other consensus algorithms at a high level.

Rick Rule  // The Coming Block Chain Gold Rush
 
21:52
Rick Rule and Sprott have been working on setting up a blockchain based gold platform. Now it's finally a reality. Just Monday it was announced that the trading platform is operational. The large gold producer Goldcorp is a shareholder in the venture and has just delivered gold bars to the Royal Canadian Mint to be held for fractional sale. This seems like a natural progression of blockchain technology. It will lower the costs and inefficiencies of buying and selling gold. It is certain to take off soon. Then let's see it spread to other commodity markets.

Blockchain 101 Ep 61 - What is scalability?
 
01:09
When Bitcoin was first created, Satoshi Nakamoto did not intentionally limit the block size, with the largest block reaching up to 32MB. At that time, an average block size is around 1 to 2 KB. Some thought that an excessive block size limit is a waste of computing resources and susceptible to DDOS attacks. Therefore, to ensure the security and stability of the Bitcoin network, Satoshi Nakamoto set the block size limit at 1MB. There was only a small number of Bitcoin users then, with small transaction volume, hence no network congestion. From 2013 till now, Bitcoin’s price has shot up dramatically, with an ever-increasing number of users. Problems such as network congestion and rising transaction fees began to surface. The Bitcoin community began looking at scaling Bitcoin by updating its underlying code, increasing its capacity to handle transactions.
