• 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.

    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...

    Anyone who's walked into a voting booth and scratched their preference onto a piece of paper knows the same thing: the voting process suffers from a dire lack of technology. Humanity put a man on the moon in 1969--why are we still voting on paper? Going digital isn't just a matter of convenience, but one of accountability—citizens the world over are increasingly losing trust in the democratic system, from miscounted votes, to denying eligible people the right to vote at all. So just how much can we digitize the act of voting? Perhaps blockchain—a public ledger technology where information is irreversibly recorded—can build a better system. Here, Internet pioneer Brian Behlendorf considers two aspects where blockchain can help, and one where it absolutely can't. Better tech can end voter di...

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?

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.

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.

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.

Anyone who's walked into a voting booth and scratched their preference onto a piece of paper knows the same thing: the voting process suffers from a dire lack of technology. Humanity put a man on the moon in 1969--why are we still voting on paper? Going digital isn't just a matter of convenience, but one of accountability—citizens the world over are increasingly losing trust in the democratic system, from miscounted votes, to denying eligible people the right to vote at all. So just how much can we digitize the act of voting? Perhaps blockchain—a public ledger technology where information is irreversibly recorded—can build a better system. Here, Internet pioneer Brian Behlendorf considers two aspects where blockchain can help, and one where it absolutely can't. Better tech can end voter discrimination at polling stations, and falsely reported totals at the state and national levels, but will we ever be able to vote on our mobile devices from the comfort of a blanket fort? Don't get your hopes up. Brian Behlendorf is the executive director of Hyperledger; for more info, visit http://www.hyperledger.org. Read more at BigThink.com: http://bigthink.com/videos/brian-behlendorf-can-blockchain-build-a-better-voting-system Follow Big Think here: YouTube: http://goo.gl/CPTsV5 Facebook: https://www.facebook.com/BigThinkdotcom Twitter: https://twitter.com/bigthink Transcript: Many people have asked: can blockchain technology help provide answers to challenges that typically have suffered from lack of technology, or that has suffered from poor technology applications. One of those being the way that voting works in the United States. I think of this in three distinct phases. There’s the phase before voting where keeping track of who is registered to vote and where they’re allowed to vote, it’s been harder than it should have been. We have a lot of examples of people showing up at polling places and being denied the right to vote and it seems like paperwork goes missing and people get removed from voting roles, that sort of thing. A public ledger that tracked who was registered to vote where and allowed people to look at that from their home machine and then confirm that when they showed up at the poll, would do a lot to reestablish trust in the process of registering to vote and validating that everybody who is entitled to vote is able to do that, providing an independent verification of that. There’s a second phase I’ll get to in a bit, but there’s a third phase, which is after the vote, when you’re taking the totals that come from a polling place, that come from vote by mail for example in Oregon. We have to kind of trust that the system works. We have to hope that everything is counted correctly at the local level and then it’s totaled up correctly at the state level and then reported nationally et cetera. And we’re fortunately at a point where the basis of that trust hasn’t been violated yet, but in many countries it is. In many countries there’s not a lot of confidence that the total from a polling place is accurately summed up. So using a distributed ledger not to track the individual votes but to track the totals from each of the polling places would be a way to allow the public to understand: 'Okay the local polling place I went and voted at is reporting a thousand votes, 500 for candidate X, 500 for candidate Y, that seems about right. I don’t know if my vote specifically counted, but I know that at least the polling place I was at counted appropriately and they didn’t try to pretend they were 100,000 votes.' So at the beginning of that process and the tail end of that process using a public distributed ledger to record that makes a lot of sense. But in the middle, the actual act of walking into a booth and registering a vote, or a lot of people want to do voting by mobile device or by computer; I’m very worried about the digitization of that. Our computers fail us all the time and malware and other threats could really step in and make it so that I think I’m voting for one candidate but it gets recorded for another. And we have to think, in the United States, we care quite a bit about the confidentiality of our vote even to the point where I get no receipt, I can’t go to a bar and prove that I voted for somebody and get a discount for it—that would be considered bribery. So we can’t simply come up with a system that puts all the original votes into a public ledger and provides proof that somebody voted a certain way or that becomes a corruptive process. So I think we still need voter-verified paper ballots as a path to auditing, but with the registration at the beginning and the summing at the end conducted by a public ledger I think we would do a tremendous amount to reestablish confidence in the voting system.

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.

As the first transmission system operator, TenneT uses networked, decentralized home storage with the blockchain to stabilize the power grid. Flexible use of battery storage reduces network-stabilizing emergency measures. After a successful pilot phase, the blockchain technology can be further expanded through IBM's open source-based solution. In a second project in the Netherlands, together with Vandebron, TenneT uses the charging of electric vehicles to keep the balance between consumption and production stable. Both pilot projects are further steps to make the electricity network fit for the future. TenneT taking power further www.tennet.eu www.tennet-virtual-vision.eu

- In the previous episode, we learned about the importance of economic survey in UPSC exam, and the gist of its 14 chapter. Now moving to the first pillar of economy i.e. "Money, Banking, Finance and Insurance." - While "money and its evolution upto bitcoin" has been covered in previous lectures ("L3") and articles but take a look at them again in the light of new developments especially regarding the meaning of legal tender, challenges to digital payment and utility of block chain technology. - Even before the invention of money, people used to trade with each other using barter system however this system, while it has some advantages, suffered from the problem of "double coincidence of wants", problems related to the divisibility and fungibility of value, did not permit industrialisation or division of labour or redistribution of national income. - Therefore money was invented, with two primary functions 1) measure of valu. And 2) medium of exchange And three derivative functions: store of value, transfer of value and deferred payment. - Over the period of time, this money evolved in five stages : 1) Commodity Money 2) Metallic Money 3) Paper Money & legal tender 4)Bank Money 5) Crypto Currency. - First we take a look at Commodity money: examples, advantages, limitations and How the problem of uniformity and purity of gold nuggets leads to invention of metallic coin money. - Metallic Money: what is the difference between full bodied coin and token coin. What is Grisham's law and debasement? How do they affect the value of coin? Powerpoints available under Mrunal.org/download - Faculty Name: You know who - Powerpoint available at http://Mrunal.org/download goto Mediafire folder - "Powerpoint" -"1_Economy_Mrunal" - there goto "BES17_Budget_Eco_Survey" and you'll find the powerpoints. - Exam-Utility: UPSC IAS IPS Civil service exam, Prelims, CSAT, Mains, Staff selection SSC-CGL, IBPS, SBI, RBI and other banking exams; LIC, EPFO, FCI & other PSU exams; CDS, CAPF and other defense services exams; GPSC, MPPCS, RPSC & other State PCS services exams with Indian Economy, Budget, Banking, Public Finance in its syllabus- with descriptive questions and answer writing.
