Bitcoin in five minutes: Blockchain technology will drastically change our lives. In the coming years, the technology behind crypto currencies such as Bitcoin will inevitably and radically change the role of traditional trusted parties such as banks, accountants, notaries, and governments. The animated video about 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 ecommerce entrepreneur and founder of IntoBitcoin.com: “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 (Senanga.net, IntoBitcoin.com).

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.

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. 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.

Blockchain is the underlying technology behind cryptocurrencies bringing together Merkle trees, Hashing & Distributed Architecture. Christopher Ellis explains. Note - At minute 17, Christopher mentioned the mining reward halving at 21,000 bitcoins but meant 210,000 blocks.

Peter Todd discusses his thoughts on how we can scale the blockchain in a sustainable manner that does not exclude people from using it. If, for example, we make block sizes too big, then people in countries with slow internet connection would have a hard time running nodes and making transactions.

Imagine a world where governments compete for your citizenships. Bitcoin and Blockchain expert Toni Lane Casserly explains how this technology could anoint people over institutions.

I mean we're all one continent once and what is a border? A border is like someone walking into your house with a can of gas and a gun and setting the can of gas down and looking at you and saying this is my house. And you're like what? Me and my indigenous family have lived here for centuries, like this is our house and colonialism says no, this is my house and if you don't want to go and like warship our deities and all these things then like you have options. And one is the gun, which could be for you, or the other is kick over the can of gas. I can just burn this down and you would have nothing left and then it would be much easier for it to be mine. And I have no capital issues rebuilding it after I destroy it. That's how we created borders. What? What kind of a world do we live in where that's acceptable? And that still acceptable all over the world today, it's just a generally not as public. But it's nuts. And do I think that we will live in a fully borderless world? That's going to take a lot of change or a lot of time and we'll see what happens with the effects of climate change, which could fundamentally have some massive impacts as far as creating what I would call a civilized refugee crisis. But the way that we're starting to think about living in a borderless world is actually through one of my technologies. And it is founded by Suzanne Tempelhof and I'm a partner in the company it's called Bitnation. And Bitnation is essentially the idea of Facebook for governance or DIY government. And we start out creating a borderless society by actually working on a human rights platform for people who have been disenfranchised. So we use blockchain technology to give refugees a global identity, a one-world citizenship. Read Full Transcript Here: https://goo.gl/Hb2iJk.

Matan Field believes we are standing at the dawn of a new era, a turning point in society, and invites us in to this changing world. First introduced by the anonymous Bitcoin inventor, Blockchain is a revolutionary new technology and concept which is now an exponential force. Are you ready to imagine a purely decentralized era of large-scale cooperation between people and computers which has never been possible before? Matan Field is a blockchain researcher and entrepreneur, dedicated to decentralise the world and make it a better place. Starting as a theoretical physicist, Matan has completed his PhD at the Weizmann Institute, researching fundamental physics and String Theory in particular. For two decades, Matan has been curious about alternative economic and organisational models, while increasingly bothered with a feeling that “something is broken”. During his postdoctoral research at the Technion, he has discovered the blockchain and founded La’Zooz, a decentralized real-time ride-sharing network. Field then co-founded Backfeed to develop the basis for decentralised governance and organisations. Matan is dedicated today to bring the first truly decentralised organisation into life. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
