The animated video about Blockchain and Bitcoin that was released today on http://bitcoinproperly.org is the first to specifically address the technology behind Bitcoin: the Blockchain. Within five minutes, it is explained how the essential functions of the “trusted third party” can be automatized through the Blockchain as well as what the implications of this are. From Bitcoin hype to Blockchain revolution: an internet of trust. With the arrival of crypto currencies such as Bitcoin, everyone around the world can trade with each other without any involvement from traditional third parties such as banks, notaries, accountants, and governments. Trade is a fundamental pillar of our economy and society, and traditional trusted parties play a crucial role in this. The technology behind Bitcoin making all this possible – the Blockchain – ensures that the essential functions of the “trusted third party’, are fully automatized through the internet. This way, these functions are as freely available, accessible, and programmable as the internet itself. The animated video, available in both Dutch and English, explains how this works, also mentioning practical applications. The implications are clear: in the coming years, the role of the traditional trusted parties will inevitably and drastically change, strongly impacting our daily lives. The creators of this animated video invite its viewers to think about and discuss the fundamental and radical innovations made possible by crypto currencies. Rutger van Zuidam founder of Dutchchain, organizer of the Dutch Blockchain Hackathon: “The Netherlands have all the assets to become Europe’s Silicon Valley of financial technology. It is possible for the Netherlands to position itself favourably in comparison to the US and UK, who are currently still ahead. The technology behind crypto currencies like Bitcoin plays an essential role in leveraging these opportunities. We hope that the animated video about the technology behind crypto currencies will positively affect this development.” Lykle de Vries: ”Bitcoin is not the new money for internet,but it is the new internet for money, value and ownership in all forms. Crypto currencies like Bitcoin are the next step in the emancipation of all world citizens, and can help create a new dynamic for democracy, society and economy.” About the creators The animated video is a non-profit initiative by designers Patrick Loonstra (www.patrickloonstra.nl) and Sebas van den Brink (sebasvandenbrink.nl) and entrepreneurs Lykle de Vries (ThesisOne.com) and Rutger van Zuidam (DutchChain.com).

Ludwin: So I think there's this false dichotomy that's pretty popular at conferences like Davos where you hear — you hear many different languages at Davos. But when I don't understand what someone is saying, I just assume they're saying, "you know, I don't like bitcoin, but the underlying blockchain technology..." I think I know how to say that in 20 languages now. So yeah, I think it's a false dichotomy. Like I said, they're both useful and they're actually on more of a continuum than people appreciate. So a lot of the work we do, for example, is linking private blockchain — where there is no cryptocurrency — into a public blockchain. But to answer your question, you're right our protocol does not have a cryptocurrency. And the reason for that is we don't need one, because the cryptocurrency — or cryptoasset — its purpose is to provide an economic incentive to a decentralized operating group. Silverstein: To keep it going? Ludwin: To keep going and we don't need that, because we already know who's going to run the business. So yes, we could create a currency to cash in on the the hype, but we're much more interested in building a real business. And so that's why we're focused on that. And that's not to suggest that there's anything wrong with creating new cryptocurrencies. Again, I think it's just such a different context; it's hard to compare them. And I think over time, especially this year, I think one of the big trends is they'll converge more than people are expecting. Silverstein: They'll converge in what way? Ludwin: They'll converge in the following way — we have different payment networks and financial markets all around the world quite fragmented; there's very little mesh or interoperability between networks. So right now, for example, if you're in China, and you open up the Alipay app and you want to send money out of China, do you know what option you have? Do you know what it says in the app? It says Western Union. So, you know, I think that is going to change. I think the interoperability between say WhatsApp — if they ever have payments — and Alipay will be something that looks somewhat like a public blockchain. So I think that's where we're going to see real penetration and links between the existing financial institutions — some of which run blockchain architecture, some of which don't — and public networks, which will, sort of, drive interoperability. And then in parallel, I think you'll continue to see cryptoassets that are serving, you know, these alternative software models that for many people, don't get them anything new, but for certain people in certain contexts, it's really a good solution for them. Silverstein: And why does the blockchain software — why does that always come with the word integrity? Ludwin: Because the core innovation and in a blockchain — now a blockchain by the way is just a data model; it's being used — to meet — to address a lot of different things in, you know, corporate marketing at an event like Davos. But the technical reality is blockchain's just a data model. It's a database innovation. And that innovation is applying cryptography to every transaction update in that database, so that anyone can independently verify whether there's been a change to the database and can independently verify therefore, sort of, the state of say a balance in a checking account, or the current custodian of a security, or the current owner of a cryptocurrency.  So it's really in the context of an institution using a blockchain, it's really about increasing the trust in them. But, as I think many people know, a blockchain can also be used without an institution — in other words a trust replacement in a more decentralized model. But in our view, a blockchain is as relevant as an accounting model as it is as a mechanism to create decentralization. It just depends on the design goal and the intention of the company or group that's deploying the technology.

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?

The REAL Value Of Bitcoin: Blockchain: Find out why the technology powering Bitcoin -- Blockchain -- is far more valuable than the currency itself. And check out my previous video on why Bitcoin is a FAKE currency here: https://youtu.be/iATMhpDd8Q4 The type of mania we’re seeing in Bitcoin is reminiscent of the 99’ tech bubble. They’re similar in that we have a majority of investors that have no clue about what they’re really investing in. The strategy in 99’ was to throw your money into anything .com related. Nowadays it’s throw your money in anything crypto related. Talk to anyone about Bitcoin and they’ll tell you it’s the future. But do they know why? Nope! In reality Bitcoin doesn’t matter. Nor does Ripple, Bitcoin Cash, Litecoin, etc. They are all replaceable. We have no idea which cryptocurrency will survive — if any. But what will survive is Blockchain — the tech that powers them all. If you’re a trader, the cryptocurrency markets are fantastic. The volatility and pure mania is perfect to take advantage off. And because it’s a new market, simple technical patterns work pretty well. (Most “investors” in this market are not even familiar with those techniques. They only know how to HODL.) But trading is short-term. If you’re looking to invest for the long-term, then you need to invest in companies working with Blockchain technology. In the video above you’ll learn: - Why the specific cryptocurrency doesn’t matter while Blockchain does - What Blockchain is and why it’s valuable - How Blockchain provides a new level of security to the market - Various ways Blockchain can be utilized Stay Fallible Investors! ***All content, opinions, and commentary by Fallible are intended for general information and educational purposes only.

This video https://youtu.be/eXJHPDs4M3Y provides an easy to understand introduction to Blockchain Technology. Please leave comments and questions below the video. Here is the full transcript for your convenience: What is a Blockchain? A Blockchain is a distributed database that multiple parties share and everyone can trust. A Blockchain network provides a mutually trusted, transparent way of sharing and transacting. Each party participating in a Blockchain network maintains their own copy of the database. What makes Blockchain secure? Transactions on the database are atomic (this means that they're processed one at a time). The next transaction will be a different write or a read, but only after the preceding transaction has completed (or failed). Each write to the database is considered a ‘block’. Each new block contains a cryptographic hash (a unique fingerprint) of the previous block, creating a chain that can always be validated by checking the hashes back to the original root block. Before a block can be committed, all participants are required to validate the transaction and provide consensus that the block can be added to the chain. This effectively makes it impossible to add a record unless all parties participating in the blockchain agree the record is valid. Because all records are chained together by their hash value, once committed to the chain, all records are immutable (they cannot be changed). It is impossible to alter a previous record without altering every party’s copy of the chain. If one node is compromised, then it can no longer participate in the chain until it regenerates the true chain from the other participants. How does Blockchain prevent double spending? A major challenge of digitising assets is the potential to spend/redeem/use an asset multiple times. Because digital assets are much easier to forge than many traditional assets (such as currency, tickets, physical coupons, etc.), a secure system is required to ensure that an asset is only used once. With Blockchain, every time an asset is used or consumed, the owner of the asset signs the transfer with a private cryptographic key. This key is unique to the owner and is extremely difficult to forge. In order to initiate the transaction, the transferrer requires both the asset and their private key. The Blockchain will check both the validity of the key, and ownership of the asset. Therefore, even if the asset is cloned, it cannot be used without the private key. Once the transaction has been committed to the chain, the owner of the asset will have changed. This means, each node that receives a second transaction requesting transfer of ownership (or redemption, etc.) will see that there was a previous transaction that already transferred the asset and will reject that transaction. This prevents a second transfer block from being added to the chain. How does Blockchain ensure privacy? Personal data and identifiers are not required to be stored in the chain. Such data is stored as a hash value which provides both anonymity and security. The user may provide data such as their name, telephone number, email address, Facebook account id, unique user name, password etc. (in reality a combination of these values is used) to determine their identity. This data is hashed to provide a unique token that can only be recreated by providing the original values, and only this hash is stored to identify the party in the chain. Since it is impossible to obtain the input values by reverse engineering a hash value, the user is practically anonymous to all parties within the chain. But, they can be validated whenever required by providing the original values used to create the hash. How is PassKit utilising Blockchain? PassKit provides a private blockchain service to parties that wish to issue, record or redeem anything of value. This can be anything from loyalty points, punch card programmes, event tickets, boarding passes, to government identification, insurance policies or claim histories, tax records and educational transcripts. We utilise existing mobile wallet technology as a gateway for transacting, validating or querying our secure, private Blockchain networks. We ensure that mobile wallet content can be validated and trusted in a frictionless, realtime manner, by both consumers and by the businesses and institutions with whom they transact.
