• The Bitcoin and Blockchain Technology Explained

    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.

  • Developing Blockchain Software

    This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges. Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns. C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do. EVENT: CppCon 2016 (http://CppCon.org) SPEAKER: David...

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?

BigchainDB fills a gap in the decentralization ecosystem: a decentralized database, at scale. It points to performance of 1 million writes per second throughput, storing petabytes of data, and sub-second latency. The BigchainDB design starts with a distributed database (DB), and through a set of innovations adds blockchain characteristics: decentralized control, immutability, and creation & movement of digital assets. BigchainDB inherits characteristics of modern distributed databases: linear scaling in throughput and capacity with the number of nodes, a full-featured NoSQL query language, efficient querying, and permissioning. Being built on an existing distributed DB, it also inherits enterprise-hardened code for most of its codebase. Scalable capacity means that legally binding con- tracts and certificates may be stored directly on the blockchain database. The permissioning system enables configurations ranging from private enterprise blockchain databases to open, public blockchain databases. BigchainDB is complementary to decentralized processing platforms like Ethereum, and decentralized file systems like InterPlanetary File System (IPFS). This talk describes technology perspectives that led to the BigchainDB design: traditional blockchains, distributed databases, and a case study of the domain name system (DNS). We introduce a concept called blockchain pipelining, which is key to scalability when adding blockchainlike characteristics to the distributed DB. We present a thorough description of BigchainDB, a detailed analysis of latency, and experimental results. The talk concludes with a description of use cases.

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.

http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/cppcon/cppcon2016 — This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges. Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns. C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do. The primary purpose of the talk is to explain what blockchains are, increase understanding of the unusual challenges developers of blockchain software experience, and to demonstrate why C++ is a good choice to address them. — David Schwartz is the Chief Cryptographer of Ripple, a distributed payment network. Also known as "JoelKatz", he is a respected voice in the crypto-currency community. David has also developed secure messaging and cloud storage software for government and military applications. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com

Short video slide about the convergence of The Internet of Things(IoT) and the blockchain. Produced by: http://complexitylabs.io/courses Twitter: https://goo.gl/Nu6Qap Facebook: https://goo.gl/Nu6Qap LinkedIn: https://goo.gl/3v1vwF Transcription: The internet is evolving into a new technology paradigm based around smart systems, the blockchain, platforms, and IoT in the coming years, these technologies will interact and converge in new and unpredictable ways The convergence of IoT and blockchain will be a major part of this evolution, enabling new automated service systems and business models... but many unresolved issues remain IOT Internet of Things is the merging of our engineered physical environment with information systems to create smart adaptive objects and environments... it is a fast-growing, increasingly complex network of connected physical systems that are able to process information and communicate peer to peer in order to enable common services. These devices are becoming increasingly ubiquitous ranging from autonomous vehicles to sensors monitoring industrial processes, to smart homes and smart cities. IoT is growing rapidly, according to Gartner the global IoT network will connect 26 billion devices by 2020. The development of an IOT infrastructure to our economies will probably be the greatest engineering challenge of our time... dealing with the sheer amount of data due to come on-stream and security are primary concerns... before mainstream Internet-of-Things adoption can really take hold in a safe and sustainable fashion, these, among other issues, will need to be resolved. Blockchain The blockchain is a secure distributed database for recording transactions... millions of computers networked to create a distributed database for recording and authenticating exchanges of value. With the blockchain, value of any kind can be exchanged directly peer to peer without a centralized authority to record and validate the transaction. The blockchain can provide an automated and secure transaction infrastructure for next generation IoT systems... in its capacity to track billions of connected devices and enable the frictionless processing of transactions and coordination between devices. This decentralized approach would eliminate single points of failure, bottlenecks and potentially make data and transactions more secure.... creating a more resilient ecosystem for devices to run on. Likewise, it would automate transactions, enabling fully autonomous service systems; reduce cost and reduce settlement time from days to seconds One example of an IoT Blockchain system is Slock, a door lock that is connected to a smart contract on the blockchain that controls when and who can open the lock. “The owner of a Slock can set a deposit amount and a price for renting his property, and the user will pay that deposit through a transaction to the Ethereum blockchain, thereby getting permission to open and close that smart lock through their smart phone.” - Christoph Jentzsch Such technology bridges the blockchain and the physical world by making automated smart contracts, thus enabling the frictionless and automated temporary exchange of assets such as bikes, parking lots or rooms. "Smart contracts, a feature of “Bitcoin 2.0” technologies such as Ethereum, could soon operate on the Internet of Things (IoT), control objects in the physical world, and power a new decentralized version of the sharing economy, for example sharing services similar to Uber and Airbnb that operate in pure P2P mode without centralized management." - Bitcoin Magazine Leveraging blockchain for IoT offers new ways to automate business processes and build distributed autonomous service systems... "The true value of the underlying technology -- the blockchain -- has only just begun to be explored, and potential applications to the Internet of Things and Smart Systems are vast."

Subscribe to Hidden Forces Here: http://www.hiddenforcespod.com/ In this Market Forces segment, Demetri Kofinas covers the latest blockchain news with Andrew Keys of Ethereum focused Consensus Systems. While most are undoubtedly glued to the bitcoin cash news that rocked the cryptocurrency industry yesterday (August 1) regarding Bitcoin’s first “hard-fork,” Andrew continues to focus on the bigger picture at hand. As fascinating as Bitcoin has been and continues to be, particularly as the technology flag-bearer for its novel blockchain technology, Andrew’s attention has been on what he believes is the true technological panacea for everything from payment processing, contract transfers, application creation – even the future of the internet as we know it. Hence, his role spear heading business development for Consensus Systems. Building on the innovation, adoption, and possibilities of Bitcoin, Andrew has immersed himself over the last several years, diving head first into what many people are calling Bitcoin 2.0 – otherwise known as Ethereum. Andrew turned an opportune meeting with the founder of Consensus Systems and co-creator of Ethereum, Joseph Lubin, into a role that has quickly evolved into Andrew sitting center stage as one of the world’s go-to business ambassadors of blockchain technology and the highly advanced Ethereum protocol. Andrew has been invited to all ends of the world to explain blockchain technology and Ethereum to industry titans in the worlds of finance and technology. Just this year alone, Andrew traveled to and spoke at the World Economic Forum in Davos, Switzerland and the Global Blockchain Financial Summit in Hangzhou, China, meeting with executives at JPMorgan Chase, Microsoft, and IBM as well as top government officials from around the world. Today, he is here with us to discuss blockchain technology, Bitcoin, Ethereum, and the explosive growth of the cryptocurrency industry – where it’s been, what it looks like today – and how it has the potential to shape all of our futures. "This is ultimately about the move away from a centralized system for organizing society towards a decentralized one that is more appropriate for the technological present," says Demetri Kofinas. Indeed, the question of centralization versus decentralization is central to the framework of blockchain technology. It also speaks to the challenges of scaling the network, which was the central concern of the bitcoin mining community that initiated the recent "hard-fork" in order to create bitcoin cash. For all of recorded history, human beings have achieved scale through a bureaucracy. Empires, nation states, corporations, etc., are all built upon layers of authority and thickets of bureaucracy. Blockchain manages to overcome this by shifting the burden of validation from the center to the periphery. In other words, no central authority is required in order to approve any transaction or mediate any dispute among users of the blockchain protocol. There is no need for third-party verification (TPV). This process is achieved through consensus. Instead of requiring the use of digital right's management software in order to manage ownership rights over music, for example, users can rely on the Ethereum's blockchain network. Rather than require a central clearing house or exchange to validate a debit or credit, you can use Bitcoin to transfer value directly from one party to another. Again, there is no need for third-party verification. The two discuss issues of security and the problem of energy consumption. They also contemplate the role of Wall Street in the cryptocurrency space, specifically its use of the Ethereum blockchain. They look at the role of government, regulations, and the adoption of blockchain technology by nations around the world. Andrew also gives his take on blockchain, and specifically Ethereum’s ability to create an entirely new Internet, built on the Ethereum blockchain. If you have been looking for a great resource for explaining "what is Ethereum" or "what is blockchain," then you have come to the right place. One of Andrew Keys' main tasks as head of Global Business Development for Consensus Systems is to help educate potential users of this technology on how it all works. You won't be disappointed.

The term 'blockchain' has been increasingly thrown around due to a rise in cryptocurrency popularity. Here is a speedy explanation of what it is and how it works. The below terms may be useful before watching the video: Encryption: - The process of converting information or data into a code, mainly to prevent unauthorized access. Hash Code: - A hash function is any function that can be used to map data of arbitrary size to data of fixed size. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes. Centralized System: - A system where decisions for the system goal are made in a central mechanism and transmitted to executive components. Distributed System: - A distributed system consists of a collection of autonomous computers, connected through a network and distribution middleware, which enables computers to coordinate their activities and to share the resources of the system, so that users perceive the system as a single, integrated computing facility.
