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 consider...

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?

Cross-chain atomic swaps allow for different cryptocurrencies to be traded with a guarantee that the funds would be received without the need for an exchange or third party. This is a breakthrough in terms of cryptocurrency technology as it could be extended to allow merchants to accept more cryptocurrencies or even used to build decentralized exchanges. Currently successful atomics swaps have been completed between Decred-Litecoin, with more cryptocurrencies to come https://en.bitcoin.it/wiki/Atomic_cross-chain_trading https://bitcoinmagazine.com/articles/decred-adds-atomic-swap-support-exchange-free-cryptocurrency-trading/ Use code "6bXKwD" and get 3% off every purchase on Genesis Mining! https://www.genesis-mining.com/a/287920 🤑 ♨️Social: http://boxmining.com Steemit: https://steemit.com/@boxmining Twitter: https://twitter.com/boxmining Facebook: https://www.facebook.com/boxmining 🤑 Buy Bitcoin: https://www.coinbase.com/join/590c3a1c8bfa31012ffacf87 💰 Secure your Crypto with Hardware Wallets: Ledger: https://www.ledgerwallet.com/r/428b Trezor: https://trezor.io/?a=6xd5fhdqqjng 💪Donations: Bitcoin : 13EvsPm3YhiCPGksQQdvQUFtsbF8FoU6Cz NEO: AHMMavFxwPA1jPB3HiF5Hq8JxeJ2soWvDW Ethereum: https://etherscan.io/address/0x58d98516363D2A5f93CE6aB4A4a909599C3EEC3a DASH: XcAREQEEunvv6rJza9LKDzdyjZ1BwBN2iK Litecoin: LXeXUr2Hr3ePgHb9aDjr4QdqA4DPXoTarU NEM: ND6WRNN2W2AZLON65EGI3Y46M4TWP3HNKSB4BGW2 Decred: DsgsSqYF2oSZ5MJeoqiEMyeJdWhdvWk8A4s 👩🏻‍🚀 Save on Amazon with Purse.io https://purse.io/?_r=Fxj40g 💱Software Wallet: Windows/Mac/linux: http://exodus.io

Entrepreneurs are driving all of the innovation today, and this episode's guest is no exception. Adam Ludwin, CEO & Co-founder of Chain created a tool that's helping top financial firms (NASDAQ, CapitalOne, Citi, Fidelity, Visa & more) deploy the blockchain. Adam demos his technology, and offers a fascinating and super clear explanation of how/why bitcoin & the blockchain were developed, how it works, common misperceptions, how the DAO hack happened & long-term effects, and how he got that insanely amazing domain name. Jason and Adam venture deep into other tech & culture territory, including whither Apple, who will buy Twitter, Snapchat v. Instagram, religion, oppressed societies, Hamilton (The Musical), and the hardest part of a startup (hint: it's not the starting up). Click to tweet "thank you" to our partners (can edit before sending): http://ctt.ec/57e3f Timestamps 00:29 Welcome from Jason. Only entrepreneurs can solve problems & innovate in technology these days. 01:51 Was introduced to bitcoin back in 2011. Thought this was dangerous, destabilizing, and transformative. Hasn't been any of these things and mostly been a disappointment to VCs. 04:05 However: out of this Blockchain has emerged as the underlying architecture of cryptocurrency, and the true innovation, here to stay. Introduces guest Adam Ludwin, CEO & Co-founder of Chain. 05:38 Adam explains origins of company as a bitcoin API. Early customers (NASDAQ, Fidelity) didn't at the time understand the mechanics of bitcoin. Adam explains the difference between digital copying (email) and digital transferring (money). 12:06 Partner break - Thank you, Braintree. 15:53 Adam tells the story of how he got the amazing domain, Chain.com. 17:54 Further debate on bitcoin, use cases. It's like bittorrent. It will always be used by people who are off the grid, or want to be. 19:55 Discussion on ethereum, the number 2 cryptocurrency behind bitcoin. Segue into the DOA (Decentralized Autonomous Organization) project. 25:35 Partner break - Thank you, Squarespace. 28:02 Back to ethereum, and its vulnerability. Its smart contract is written by a program. On to the DOA hack & fall-out. (Two ethereum networks now.) Long-term repercussions on financial institutions. 35:37 Example of The Pudding Guy, accumulating many frequent flyer miles by taking advantage of a promotion by Healthy Choice Foods in 1999. Healthy Choice Foods awarded him 1,253,000 frequent flyer miles. 37:46 Financial infrastructure is so broken. Fintech startups are trying to patch up current systems. We are rewiring the underlying system. 40:53 Adam does a Chain demo, with wallet-to-wallet transfers of different kinds of digital currencies, including reward points, $, also showing the underlying blockchain architecture. 48:21 Remind Jason of Justin Timberline's sci-fi movie "In Time" and his arm code with a bitcoin balance. 49:28 Chain business model. Expensive and scales with volume. We did first production network with NASDAQ. For private market security. Their entire cap table is on blockchain. 51:28 Theory that in the future, company stock will move as freely as public company stock. Jason asks, if you could buy only three stocks and hold them for the rest of your life? 52:56 Discussion about Apple. Still innovating? They break it down. Versus Tesla, Uber, Google, Amazon, Square. 01:00:00 Onto Twitter. It's a mess, and will it ever go away as a product?Who will buy it? (Google or Facebook/) 01:07:33 Onto to Instagram v. Snapchat. Facebook just straight up copied Stories, and is unapologetic. Debate: Jason is disgusted, Adam thinks it's good for users. Other examples of copycats. 01:14:52 Example of Theranos and people should start calling b.s. more. Who is candid in Silicon Valley? Segue into Sapiens book and the thesis that indigenous not necessary better, there is such a thing as progress. Onto globalization and the need for some states/religions to evolve. 01:19:40 Chain is hiring! Who are they looking for? What is the culture like? Be interdisciplinary. 01:20:26 How hard it is to be a founder and one of the most important lessons of entrepreneurship.

A film by Manuel Stagars http://www.blockchain-documentary.com In 2008, Satoshi Nakamoto invented bitcoin and the blockchain. For the first time in history, his invention made it possible to send money around the globe without banks, governments or any other intermediaries. The concept of the blockchain isn’t very intuitive. But still, many people believe it is a game changer. Economist and filmmaker Manuel Stagars portrays this exciting technology in interviews with software developers, cryptologists, researchers, entrepreneurs, consultants, VCs, authors, politicians, and futurists from the United States, Canada, Switzerland, the UK, and Australia. The Blockchain and Us is no explainer video of the technology. It gives a view on the topic, makes it accessible and starts a conversation about its potential wider implications in a non-technical way. The film deliberately poses more questions than it answers.

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.
