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?

How Blockchain Works - in 2 Minutes
 
02:08
What is the Blockchain? This 2 minute video explains it in a very easy way. As usual, please leave you questions and ideas in the comments. with love your MinuteVideos Team Video Script: Scene 1 Blockchain is a Peer to Peer software technology that protects the integrity of a digital piece of information. It was invented to create the alternative currency Bitcoin but may be used for other cryptocurrencies, online signature services, voting systems and many other applications. In this video we explain how it works and what makes it special. Scene 2 Everyone uses paper money. When you get a 10 dollar bill you trust that it's not fake. If instead someone sent you an email saying "here's 10 dollars" you probably wouldn’t trust it. But when we "transfer money", use an ATM or pay with a deposit card that's pretty much exactly what we do. We're sending money in a digital message. Scene 3 To make sure no one's cheating or sending money they don't have, these “messages” go through a few trusted banks that keep a record of everything. They know how much money everyone has and deduct it properly for every transaction. Scene 4 But this becomes expensive when there’s a million transactions around the world every minute. The Economist estimates that banks charged us more than 1.7 trillion dollars to process these payments in 2014. That’s about 2% of the entire world economy! With blockchain we can save a lot of this cost because it lets us send money just like sending an email. Scene 5 Instead of sending a lot of payment information through a few servers, blockchain uses thousands of personal computers on the internet. All transactions are copied and cross checked between every computer in a system wide accounting book called the ledger, which becomes very safe at scale. Scene 6 Blockchain doesn’t just allow us to create safe money online, it lets us protect any piece of digital information. This could be online Identity cards, voter ballots, contracts and many other “legal instruments”, bringing bureaucracy into the 21st century.

Was ist eine Blockchain - eine sehr detailierte Erklärung - Einfache Beschreibung einer Blockchain...#bitfantastic #bitcoin #blockchain #ethereum #ripple #bch #bct #xbt #eth #xrp #cryptofit #crypto Hallo und Herzlich Willkommen auf BITFANTASTIC. Mein Name ist Eduard Prinz und in meinen Videos geht es um Blockchain, Bitcoin, Ethereum, Dash, Iota, Ripple und sonstige sinnvolle Kryptowährungen und Blockchain Anwendungen und Services der Zukunft. Ich möchte euch einerseits die Grundlagen der Blockchain Technologie, der Kryptografie, der Programmierung im Bereich der Blockchain und Kryptowährung aber auch im Bereich Investment in Crypto Currency und worauf man achten sollte, zeigen. Es wird Tutorials auf technischer Ebene und ein Diskurs mit dir zusammen über schlaues und rationales investieren in die Zukunft geben;) Viel Spaß wünscht Dein Eduard Prinz, MSc BSc (computer science) ☞ Teile das Video gerne, wenn es dir gefallen hat ;) ABONNIERT den Kanal kostenlos und VERGESST NICHT DIE GLOCKE ANZUSCHALTEN ;) Bitte hinterlasse gerne deine Meinung zu dem Thema! Danke für deine Unterstützung ;) BLOCKCHAIN Ist ein System zur Übertragung und Sicherung von Daten (Informationen, Werte), in einem Register. Blockchain ist also die Kombination aus Transaktion von Daten und die sichere Hinterlegung von Transaktionsdaten. Bitcoins sind eine elektronische Währung, manchmal auch Kryptowährung genannt. Sie basiert auf einer Blockchain. Die Identität des Gründers, Satoshi Nakamoto, ist unbekannt. DISTRIBUTED LEDGER Ist ein Dezentrales Verzeichnis in dem alle Transaktionsdaten, nach Abschluss einer Verifikation (Prüfverfahren), auf protokollebene physich persitiert werden und öffentlich, lückenlos und transparent sind. Wir auch als verteilte Datenbank bezeichnet. DOUBLE SPEND Was ist das Double Spend Problem? Bitcoins sind genauso Dateien und wie alle anderen Dateien kann man diese auch kopieren, sprich vervielfachen und anschließend umbenennen. Danach könnte man die Dateien auf seinem Computer speichern und die Bitcoin Blockchain auf einen alten Stand zurücksetzten. HARD FORK Immer wieder wird ein bestimmter Begriff in Zusammenhang mit Bitcoin und Altcoins erwähnt und das ist Hard Fork. Aber was ist eigentlich ein Hard Fark konkret? Es lässt sich mit der Android Welt leichter erklären. Google bringt als Federführendes Entwickler Team eine neue Android Betriebsystem Version heraus. SATOSHI NAKAMOTO Ist ein Pseudonym für Erfinder des Blockchainalgorithmus und der Recheneinheit Bitcoin. Er hat im November 2008 die Referenzimplementierung Bitcoin Core entwickelt und veröffentlicht. Welche Person oder Personengruppe sich tatsächlich hinter diesem Pseudonym verbirgt, ist bis heute unbekannt. Der Proof of Work (PoW) ist ein Verfahren zum Prüfen und Verifizieren von Transaktionen, die in verschiedenen Blöcken gespeichert werden. Geprüft wird auf Richtigkeit und Vollständigkeit basierend auf einem physikalischen Nachweis in Form von Thermischer Energie (Wärmeentwicklung) die durch Rechenleistung (also Arbeitsaufwand) entstanden ist. Proof of Stake ist ein Prozess zur Erzeugung von neuen Coins. Wie viele Coins für einen Monat in das Verfahren gegeben und geprüft werden entscheiden die Teilnehmer. Anschließend werden nach dem Monat die Coins wieder freigegeben und per Zufall an neue Teilnehmer verteilt (belohnt). Auf diese Weise kann sichergestellt werden, dass kein Angriff von außen stattgefunden hat. Jedoch ist das Proof of Stack-Verfahren sehr anfällig für Double Spend.

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?

Une première définition de la blockchain
 
01:41
Introduction à la blockchain Slide 1 Avec le buzz actuel, tout le monde a entendu parler du bitcoin, mais plus rare sont ceux qui connaissent la blockchain, une technologie révolutionnaire qui permet aux cryptomonnaies de fonctionner. Side 2 Ce qu’il est avant tout important de comprendre, c’est qu’une blockchain est une base de données rien de plus. Celle-ci vise à stocker les transactions réalisées entre les membres d’un réseau d’ordinateurs organisés de manière décentralisée. Slide 3 Si nous prenons l’exemple du bitcoin qui est la première cryptomonnaie à avoir utilisé la blockchain, ce qu’il est important de retenir pour le moment c’est le bitcoin est un réseau de personnes qui réalisent des transactions les uns avec les autres. Slide 4 Ces personnes sont réparties sur toute la planète et utilisent leur ordinateur et internet pour réaliser des transactions en utilisant des bitcoins. Slide 5 Chacune de ces transactions est enregistrée au fur et à mesure dans des blocks qui sont ensuite ajoutés de manière irréversible à la blockchain. Slide 6 La grande nouveauté c’est que ce sont les membres du réseau qui mettent à jour la blockchain et plus un tier de confiance. Certain membres du réseau, les mineurs, ont en effet pour mission d’ajouter les transactions dans les blocks et les blocks à la blockchain. Slide 7 Pour résumer, la blockchain permet d’enregistrer de manière sécurisée, les transactions réalisées entre les membres d’un réseau décentralisé. Slide 8 Dans le prochaine vidéo, nous décrirons un peu plus précisement ce qu’est une blockchain alors restez connectés !!

A Simple Explanation Anyone Can Understand You'll receive $10 in free bitcoin by signing up with this link http://bit.ly/2oesV41 Blockchain Revolution Book: http://amzn.to/2nXGGqY Buy Ethereum: http://bit.ly/2oesV41 Ethereum Course: http://courses.blockgeeks.com/ What is Ethereum for beginners? At its simplest, Ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications. Is Ethereum similar to Bitcoin? Well, sort of, but not really. Like Bitcoin, Ethereum is a distributed public blockchain network. Although there are some significant technical differences between the two, the most important distinction to note is that Bitcoin and Ethereum differ substantially in purpose and capability. Bitcoin offers one particular application of blockchain technology, a peer to peer electronic cash system that enables online Bitcoin payments. While the bitcoin blockchain is used to track ownership of digital currency (bitcoins), the Ethereum blockchain focuses on running the programming code of any decentralized application. In the Ethereum blockchain, instead of mining for bitcoin, miners work to earn Ether, a type of crypto token that fuels the network. Beyond a tradeable cryptocurrency, Ether is also used by application developers to pay for transaction fees and services on the Ethereum network. “Bitcoin is first and foremost a currency; this is one particular application of a blockchain. However, it is far from the only application. To take a past example of a similar situation, e-mail is one particular use of the internet, and for sure helped popularise it, but there are many others.” Dr Gavin Wood, Ethereum Co-Founder What is a smart contract? Smart contract is just a phrase used to describe computer code that can facilitate the exchange of money, content, property, shares, or anything of value. When run on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Because smart contracts run on the blockchain, they run exactly as programmed without any possibility of censorship, downtime, fraud or third party interference.

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.

Bitcoin & Cryptocurrency...What is it?
 
04:52
You’ve likely heard of Bitcoin and possibly other cryptocurrencies like Ethereum, Dash and Litecoin… But what really is cryptocurrency? Our video will explain it all to you! Cryptocurrency at its core is just mathematics, a digital currency formed from cryptography. Cryptography is by definition “the art of solving or writing codes.” But in terms of mathematics and computer coding, cryptography uses algorithms and protocols to secure and scramble information into an encrypted format. Imagine carefully placing letters into boggle, spelling out several words. Encryption is just the action of shaking up that boggle board, while decryption is the process of putting the original messages back together. Cryptography is all that cryptocurrency actually is. It’s an encrypted string of data that’s been encoded to signify a single specific unit of currency. Solving mathematical problems based specifically on cryptography produces cryptocurrency, a process known as mining. But unlike fiat currencies, cryptocurrencies are completely digital. So there’s no physical form of it. You’re never going to be able to hold a bitcoin. You can, however, hold it digitally in a wallet. Other names for crypto currencies include digital currencies, virtual currencies, or crypto for short. Crypto uses peer-to-peer networks that distribute information and transaction data throughout nodes on the network. This makes it decentralized and allows a transaction of this cryptocurrency to take place in a different manner than traditional finance systems. Cryptocurrency is not backed by a banking institution or any other centralized financial institution. Rather because it runs on a decentralized network such as a blockchain, it’s backed by the protocols, and the cryptography the network calls for and the users of the network give valued to it.
