  • 3 Reasons to Build with Blockchain

    Blockchain is a distributed data technology that enables business networks to work together in ways that weren't possible before. Blockchain can help businesses reduce multi-party transaction settlement times to near zero, can reduce overheard, and can reduce risk in tampering and collusion. Instead of working in silos, we can now work peer-to-peer in a business network, all collaborating against a shared ledger.

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?

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.

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.

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."

It has big-data performance levels, a querying system, and a permissioning system that supports public and private versions. It's complementary to decentralized processing platforms like Ethereum, and decentralized file systems like IPFS. BigchainDB is written in Python. This talk describes BigchainDB. 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.

Bockchain Enterprise: An Interview with The CEO Of Nuco http://blockgeeks.com/blockchain-enterprise/ My name is Matthew Spoke. I am the Founder & CEO of Nuco. We are a Toronto-based enterprise blockchain software company. We have been around for about seven months now. Nuco is a software company that focuses on building blockchain for networks in enterprise companies. We essentially piggybacked off of some of these open source protocols and decided that this would be an interesting technology to apply in the context of what could close the network of known participants, such as banks, hospitals, insurance companies, you name it. The same general purpose infrastructure that Ethereum is to the public domain, we wanted to build a version of that intended for a close network of participants. A simple example that people often point to is in financial services, being able to create a close-payment network, for example, between a group of domestic banks. In Canada take the five biggest Canadian banks and, say, they wanted to create a faster payment or settlement system, they might decide to do that on the distributed network rather than creating an intermediary organization for that. Outside of finance, we have also done some proof of concept in as remote use cases as healthcare or IoT. In healthcare we did a proof of concept around pharmacies and clinics existing on a network together so that they could track the issuance of prescription drugs and verify that the prescription was legitimate, that it wasn’t being used at two different pharmacies, and so solving this idea of fraud in the prescription world. That’s another example. The market that I look at when I think about spreading around is the enterprise market. We have two focuses. When we say enterprise we say, for example, the Fortune 500 companies that are the incumbents in these industries, and the banks and the insurance companies that don’t want to be disrupted by this new technology. The other category of enterprises is the new software companies that are in fact the disrupters, the ones that are coming in, our generation of the PayPals of the world that are going to be like the new bank or the new insurance company. So we’re trying to make sure that what we’re building is relevant to both of those groups. But today when you look at running any type of proof of concept or eventually going to production on a network like Bitcoin or a network like Ethereum, a lot of the challenges have to do with performance of those networks, like how many transactions can you process, the regulators wanting to have some sort of control as to who participates in these transactions, so can you close off these networks. There is also scalability and security and all these kind of high-level bucket items. Ethereum’s recent challenges have pointed out the fact that it’s probably a long way from being able to process real financial services transactions in a regulated environment. So we’re trying to solve all of those things with a built-for-purpose infrastructure that is intended for these enterprises users. There has been a healthy amount of proof of concepts in prototypes and labs and RnD that is happening. Everybody seems to be coming to a similar list of limitations. We hear it from every customer we talk to, it’s always about performance, security, scalability, integration requirements. The blockchain world operates in a little bit of a vacuum, so the [crosstalk 03:15] companies a blockchain. But in reality those blockchain networks are going to have to integrate into your sales forces, your Oracles, your SAP systems, or others. These are the real-world implications that have not been solved yet, because everybody has done their first proof of concept to say, hey, I don’t want to tokenize something that might represent like a stock or a prescription drug. How do I implement that into an existing process is the next step that people haven’t figured out yet. We made a pretty conscious decision upfront that we were going to hire talent locally in Toronto. We wanted to grow a team that had the synergies of being in the same room together. So we opened an office here, we made sure that the people we were recruiting could physically be in that office, especially because we’re bringing on people at different levels of experience with this technology. We found that they could learn a lot faster by sitting next to somebody who might be slightly more experienced than them. But that means that we were limiting our pool of talent to graduates from universities that are around the Toronto area, and we’ve got some great schools, but it’s still limiting to a certain extent. The second thing that became evident to us is we were not only looking for blockchain talent, we were looking for talent that was smart enough and well established enough to learn how a blockchain infrastructure changes the way you build software

Blockchain reputation systems have the potential to change how we think about our digital (and real) reputations. What would it mean to have a universal rating tied to our identity? Is it good or bad? ---------------- Music (with permission): Stendeck - The Silence After This Stendeck.com
