Bitcoin Q&A: Data integrity and validation of keys
 
11:23
How is SHA-256 used to verify data integrity in Bitcoin? What does it mean to sign a message? Is there a difference in the validation process of compressed versus uncompressed keys?

How Bitcoin Works in 5 Minutes new 2018 update
 
05:06
How Bitcoin Works in 5 Minutes How does Bitcoin work? This is a question that often causes confusion. Here's a quick explanation! The basics for a new user As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once. Bitcoin Balances - block chain The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography. Transactions - private keys A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining. Processing - mining Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends. ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ bitcoin price bitcoin news bitcoin to usd bitcoin cash bitcoin price chart bitcoin value bitcoin mining bitcoin stock bitcoin gold bitcoin wallet bitcoin bitcoin atm bitcoin atm near me bitcoin account bitcoin address bitcoin analysis bitcoin app bitcoin amazon bitcoin alternative bitcoin address lookup bitcoin asic a bitcoin worth a bitcoin miner a bitcoin mogul goes broke a bitcoin wallet a bitcoin atm near me a bitcoin governance network a bitcoin address a bitcoin miner in every device a bitcoin value a bitcoin to naira bitcoin buy bitcoin bubble bitcoin blockchain bitcoin billionaire bitcoin block explorer bitcoin bank bitcoin basics bitcoin buy or sell bitcoin broker bitcoin blockchain size bitcoin b font bitcoin miner.b bitcoin b symbol mel b bitcoin buy bitcoin capital b bitcoin b-eleven bitcoin plan b bitcoin b-wallet bitcoin b&h bitcoin bitcoin calculator bitcoin crash bitcoin cash to usd bitcoin current value bitcoin china bitcoin core bitcoin cash wallet bitcoin cash vs bitcoin bitcoin cash price chart c bitcoin miner c bitcoin library c bitcoin wallet bitcoin ac id bitcoin c sharp bitcoin chart bitcoin miner-c pup bitcointalk c-cex bitcoin c== c-cex bitcoin bitcoin definition bitcoin difficulty bitcoin debit card bitcoin documentary bitcoin down bitcoin dollar bitcoindark bitcoin diamond bitcoin debit card usa bitcoin day trading bitcoin.d bitcoin xt d bitcoind backup d-wave bitcoin mining the d bitcoin atm d'angelo bitcoin system d bitcoin init.d bitcoind d las vegas bitcoin /etc/init.d/bitcoind bitcoin exchange bitcoin exchange rate bitcoin explained bitcoin ethereum bitcoin explorer bitcoin exchange rate usd bitcoin ethereum litecoin bitcoin elon musk bitcoin energy consumption bitcoin exchange usd bitcoin e wallet bitcoin e.g. crossword bitcoin e.g. crossword clue bitcoin e commerce bitcoin e-currency bitcoin e money bitcoin e card bitcoin ebook bitcoin e-voucher bitcoin e pill bitcoin fork bitcoin forecast bitcoin for dummies bitcoin founder bitcoin faucet bitcoin forum bitcoin fork november bitcoin fork date bitcoin forecast 2018 bitcoin farming price of bitcoin brother john f bitcoin bh f bitcoin msil bitcoin miner-f bitcoin graph bitcoin gold fork bitcoin gold wallet bitcoin growth 2018

https://www.bitcoinlifestyles.club | Tron Wallet Me is the best AND most secure mobile wallet option for Tron / TRX! It is in fact the best wallet for Tron overall, and in this Tron Wallet User's Guide, I will teach you everything you'll need and want to know about this amazing Tron Wallet! I had previously recommended the wallets TronScan and TronWatch in my previous blog posts, but it turns out that development support is being dropped for the TronWatch wallet. The wallet’s development has shifted their focus to the TronWatch Market, which will be a Decentralized Exchange that launches sometime in 2019. This basically means that the TronWatch wallet as it stands is no longer going to be updated and I can no longer recommend using it.] If you are using TronWatch, you should upgrade to using Tron Wallet Me right away! It's really easy to do so, just install it to your mobile phone, and then use your private key [found in your TronWatch or Tronscan wallets] to import your Tron wallet to your new Tron Wallet Me. It's really easy and quick to do so! And I will also show you how that works in the video, so be sure to watch and learn how its done... In this video you will learn all about the layout and the features and functions of the Tron Wallet Me app. I will show you how to: - How to create a new Tron Wallet Me wallet instance from scratch - How to backup your wallet - Freeze Your Tron for Tron Power - How to vote in the super representative elections and earn crypto airdrops daily. - How to participate in Token Sales / ICOs - How to play / use Tron Dapps / DAPPS REVIEW!!! - How to use the various options in the Settings menu - How to secure your Tron Wallet, using the various security settings - How to earn the TronCraft CFT currency [Tron TRC20 token] and use it in STAKING to earn TRX for free! [this leverages a certain Tron Dapp] Earning from the daily airdrops with your Tron earnings and ready to further expand your residual income with Tron? Good news for you, is that I found an expansion strategy where you can take your airdrop earnings and leverage them to create an additional residual income through Tronbet and the ANTE Token, check out my video tutorial that teaches you how: https://youtu.be/j5zLpQ7zN1g Just getting started and still confused about cryptocurrency?

BlockChain Crypto Currency, Bitcoin / Z Cash, Ethereum, Litecoin
 
04:45
BlockChain Crypto Currency, Bitcoin / Z Cash, Ethereum, Litecoin A blockchain facilitates secure online transactions. A blockchain is a decentralized and distributed digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the collusion of the network. This allows the participants to verify and audit transactions inexpensively. They are authenticated by mass collaboration powered by collective self-interests.[33] The result is a robust workflow where participants' uncertainty regarding data security is marginal. The use of a blockchain removes the characteristic of infinite reproducibility from a digital asset. It confirms that each unit of value was transferred only once, solving the long-standing problem of double spending. Blockchains have been described as a value-exchange protocol. This blockchain-based exchange of value can be completed more quickly, more safely and more cheaply than with traditional systems. A blockchain can assign title rights because it provides a record that compels offer and acceptance. A blockchain database consists of two kinds of records: transactions and blocks.Blocks hold batches of valid transactions that are hashed and encoded into a Merkle tree.[1] Each block includes the hash of the prior block in the blockchain, linking the two. Variants of this format were used previously, for example in Git. The format is not by itself sufficient to qualify as a blockchain. The linked blocks form a chain.[1] This iterative process confirms the integrity of the previous block, all the way back to the original genesis block. Some blockchains create a new block as frequently as every five seconds. As blockchains age they are said to grow in height.

Hardware Wallet Hack: Ledger Nano S - f00dbabe
 
15:34
It was found that the Ledger Nano S bootloader can be tricked into flashing and executing untrusted firmware. Research Site: https://wallet.fail/ Twitter: https://twitter.com/walletfail Thomas Roth: https://twitter.com/stacksmashing original wallet.fail talk: https://www.youtube.com/watch?v=Y1OBIGslgGM The bootloader is used to update the firmware of the 'non-secure' processor in the Ledger Nano S and has full control over the display, USB and the buttons.

WHAT IS BITCOIN AND HOW IT WORKS in Hindi (2018)

As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once. Balances - block chain The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography Transactions - private keys A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining Processing - mining Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain.

How Blockchain Works ?
 
06:05
A #blockchain is the structure of data that represents a #financial #ledger entry, or a record of a transaction. Each transaction is digitally signed to ensure its authenticity and that no one tampers with it, so the ledger itself and the existing transactions within it are assumed to be of high integrity. How do #blockchains work? When a new transaction or an edit to an existing transaction comes in to a #blockchain, generally a majority of the nodes within a #blockchain implementation must execute algorithms to evaluate and verify the history of the individual #blockchain block that is proposed. If a majority of the nodes come to a consensus that the history and signature is valid, the new block of transactions is accepted into the ledger and a new block is added to the chain of transactions. If a majority does not concede to the addition or modification of the ledger entry, it is denied and not added to the chain. This distributed consensus model is what allows #blockchain to run as a distributed ledger without the need for some central, unifying authority saying what transactions are valid and (perhaps more importantly) which ones are not.

Trading Psychology Tips With Tim Grittani
 
45:43
In Tim Grittani’s presentation at the 2018 Trader & Investor Summit, he discusses two important topics. First, the basic tips for tracking setups, which are his edge and second, his tricks to help you with the psychology behind trading as it can be a challenge! 🔴 Subscribe for more FREE Stock Trading tips: https://www.youtube.com/channel/UCoSG43KFjTe0trsteSQ46Ng?view_as=subscriber?sub_confirmation=1 Share this video with a fellow Trader: https://youtu.be/zuSJymfAs8E ✅ Links I mention and recommend: Join Tim's Challenge here: https://bit.ly/2Ou1UIc Get my weekly stock watchlist here: https://bit.ly/2U4PzQA ✅ Recommended video: https://youtu.be/LcH2C5YgCQE ✅ Recommended playlists: Day Trading 101: Starter Videos: https://www.youtube.com/watch?v=sxhDIeYxNpE&list=PLTKUP0v0mxhvcNcP55fLthMRuTep2SGzY Advanced Day Trading Tips: https://www.youtube.com/playlist?list=PLTKUP0v0mxhsG4FCc4go7v4EOvyeNubJS My Millionaire Students - Are You Next?: https://www.youtube.com/playlist?list=PLTKUP0v0mxhtFSV2MDrpS6hziwptlpv4_ Trading with the Tims: https://www.youtube.com/playlist?list=PLTKUP0v0mxhvhVuORoUdAQ1yCAZ6RAI_R ✅ Follow Tim Sykes and his trading travels: Instagram: https://bit.ly/1Remh9f Facebook: https://bit.ly/2ItKo3A Twitter: https://bit.ly/2P46g8n FULL DESCRIPTION There are two things people ask Tim Grittani about a lot. The first is tracking setups, which are his edge. And the other is for trading psychology tips because the mental strain of trading can be a big challenge. What do you think about when you want to track a new setup? First thing you need is clear criteria. You also want to condition yourself to value consistency. It can help you trade with more confidence. Everyone’s different. There’s no right or wrong way. Tim starts by only looking at the open, high, low, and close. Now, it's still possible to further refine this. This is just step one of his journey when he goes into a spreadsheet. Spreadsheet tracking is huge in Tim’s strategy. Unfortunately, many people don’t understand Excel. Taking an online Excel class is an affordable, easy way to educate yourself on something that can really help you in your trading strategy going forward. Back to Tim’s strategy ... he casts a wide net and works from there. You can start big and then narrow down your list. Find ways to cut out some of the losers. Make it more consistent. Now let’s talk about trading psychology. Don’t click away — this is important! Maybe you have one or two setups that you’re very comfortable with and good at. Those setups aren't always there on any given market day. Slow days happen, and when they do, if you're in a chat room or on Twitter, you might get antsy. Maybe you see someone posting about a gain or some random big runners — you start to get that itch. It can be hard to tune out when you see others getting in on some action. You start to feel the FOMO … fear of missing out. You start to think you should be doing something too. Before you know it, you're in a random trade. You chased an entry. That usually ends with bad results. You've got to learn to ignore that noise. It’s a mental trap. No matter how confident you feel, no matter how much you think you know early on ... You're gonna face things in the market that you haven't seen before. We have these plays every year called ‘black swan events.’ It’s where you might see a pattern that works 99 out of 100 times ... but that one time, it doesn't work. It just decimates people. Remember, all traders deal with loss. Don’t let a loss be from carelessness. You have to be meticulous. You have to assume that you know less than you think you do. And you have to trade small. Those things can help you put everything in perspective. How does tracking your trades help you? What struggles do you face with trading psychology?

What is HASH FUNCTION? What does HASH FUNCTION mean? HASH FUNCTION meaning & explanation
 
01:57
What is HASH FUNCTION? What does HASH FUNCTION mean? HASH FUNCTION meaning & explanation. 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, hash sums, or simply hashes. One use is a data structure called a hash table, widely used in computer software for rapid data lookup. Hash functions accelerate table or database lookup by detecting duplicated records in a large file. An example is finding similar stretches in DNA sequences. They are also useful in cryptography. A cryptographic hash function allows one to easily verify that some input data maps to a given hash value, but if the input data is unknown, it is deliberately difficult to reconstruct it (or equivalent alternatives) by knowing the stored hash value. This is used for assuring integrity of transmitted data, and is the building block for HMACs, which provide message authentication. Hash functions are related to (and often confused with) checksums, check digits, fingerprints, randomization functions, error-correcting codes, and ciphers. Although these concepts overlap to some extent, each has its own uses and requirements and is designed and optimized differently. The Hash Keeper database maintained by the American National Drug Intelligence Center, for instance, is more aptly described as a catalogue of file fingerprints than of hash values.

Block Digest #2: Cryptocurrency in North Korea and the ‘Original Vision’ of PayPal
 
31:51
Welcome to episode #2 of Block Digest! (Wednesday, August 16th 2017) Join us: https://bitcoinmumble.com/ The topic for today is "Cryptocurrency and the Original Vision of PayPal," a discussion on David Sacks' claim that blockchain-based cryptocurrencies like Bitcoin and Ethereum resemble ideas that PayPal had back in its early days, of creating 'the new world currency.' Is this just a PR move in response to a burgeoning competitor or did they truly stray from a goal to build the new money? We also talk about Bitcoin in North Korea and efforts to undermine the division using weather balloons.

A Reference Architecture for Digital Health: The Health Catalyst Data Operating System
 
01:26:13
Table of Contents Today's Storyline 0:36 Strategic Options for a Healthcare Digital Platform 7:04 The Healthcare Analytics Adoption Model 10:26 Health Catalyst DOS™ & Product Overview 12:38 Mistakes Made and Lessons Learned 32:13 Q&A 49:07 There are essentially four strategic options to address the enterprise data platform requirements of today’s healthcare systems: (1) build your own, (2) buy from EHR vendors, (3) look to a Silicon Valley high-tech startup, and (4) partner with Health Catalyst or a handful of similar companies. In this webinar, Health Catalyst’s CTO, Dale Sanders, comments on all four approaches, hoping to help you to assess your organization’s strategy against the options and vendors in each category. It’s been exactly three years since Health Catalyst embarked on a major investment in its next-generation technology, the Data Operating System (DOS™) and its applications. This webinar is an update on the progress, less about marketing the technology, but rather offering DOS as a reference architecture that can support analytics, AI, text processing, data-first application development, and interoperability, as an all-in-one agile cost-savings architecture. In addition to the successes, Dale comments on the challenges that Health Catalyst has faced under a very ambitious DOS development plan. In its current state, DOS has made some significant improvements to overcome early mistakes, and is now a very solid enterprise data platform. In the interests of industry-wide learning, Sanders will talk transparently about those mistakes and how those learnings are being applied to the DOS platform, positioning it to evolve gracefully over the next 25 years. View the webinar to learn how the DOS reference architecture: - Helps manage the 2,000+ compulsory measures in US healthcare - Enables applications as varied as a real-time patient safety surveillance system, and an activity-based costing system in one platform - Can ingest data of any type or velocity from over 300 healthcare source systems and growing - Bundles tools, applications, and analytics that would cost 3-6x more to build on your own - Compares to EHR vendors as an option to serve as an enterprise data and analytics platform - Is a performant, sustainable, and maintainable platform for deploying AI models in the natural flow of the healthcare data pipeline - Provides curated data content and models while still allowing for the agility of a late binding design option - Functions as a reference architecture that all healthcare organizations and vendors will ultimately have to build in their pursuit of digital health

Plz like and share Website link=https://goo.gl/RN17mo Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks! There are no transaction fees and no need to give your real name.A cryptocurrency (or crypto currency ) is a controversial [1][2] digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets. [3][4][5] Cryptocurrency is a kind of digital currency , virtual currency or alternative currency . Cryptocurrencies use decentralized control[6] as opposed to centralized electronic money and central banking systems. [7] The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain , that serves as a public financial transaction database. [8][9] Bitcoin , first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency. [10] Since then, over 4,000 altcoin ( alternative coin ) variants of bitcoin have been created. [11][12][13][14] Formal definition According to Jan Lansky, a cryptocurrency is a system that meets six conditions: [15] 1. The system does not require a central authority, distributed achieve consensus on its state [ sic ]. 2. The system keeps an overview of cryptocurrency units and their ownership. 3. The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units. 4. Ownership of cryptocurrency units can be proved exclusively cryptographically . 5. The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units. 6. If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them. In March 2018, the word " cryptocurrency " was added to the Merriam-Webster Dictionary. [16] Overview Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System , corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto. [17] As of May 2018, over 1,800 cryptocurrency specifications existed. [14] Within a cryptocurrency system, the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners : who use their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme. [18] Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation. [19] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement. [3] This difficulty is derived from leveraging cryptographic technologies. Architecture Blockchain Main article: Blockchain The validity of each cryptocurrency's coins is provided by a blockchain . A blockchain is a continuously growing list of records , called blocks, which are linked and secured using cryptography . [17][20] Each block typically contains a hash pointer as a link to a previous block, [20] a timestamp and transaction data. [21] By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". [22] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance . Decentralized consensus has therefore been achieved with a blockchain. [23] It solves the double spending problem without the need of aA

Aeternity ICO - 29th May. How to invest into ICO ?
 
04:26
➤ A new project called Aeternity http://www.aeternity.com/, consisting of a team of experienced developers, announced the beginning of the first stage of sales. The first stage of the sale of tokens will be held from 3 to 6 April 2017. Only 3 days! This is a very short time for the ICO. In total, there will be two stages of selling Aeternity tokens with a break of 45 days. Step 1 1 ETH = 1000 AE. Bonus +100 AE for the first 24 hours. Duration 72 hours. Step 2 Duration 3 weeks 1 ETH = 750 AE in the first week. Bonus +50 AE for each ETH 1 ETH = 700 AE in the second week. ➤ One of the products of the project is Oracle, the so-called Oracle Machine, a more advanced work of the 21st century than the Turing machine of the 20th century. It can answer any question in a single step. This machine is based on the latest research in theoretical computer science. Unlike the projects Augur and Gnosis, Aeternity creates a decentralized "oracle", much more powerful and safe to use. The internal structure of the Aeternity project uses a consensus mechanism based on verifying the data of the "oracles" that are independent sources of data and interact with the blockbuster via a special API called AERI. Consensus in the system is achieved by using a specially developed combined algorithm Proof-of-Work (PoW) and Proof-of-Stake (POS). ➤ The developers believe that using the "oracle" is the best solution, since it avoids layering of the confirmatory actions of the platform and makes the possibilities of transactions infinitely large and does not interfere with each other. The important point is that the parties to transactions-sending and receiving side, interact only with each other Through a special decentralized application, without contributing its data to the block. However, if necessary, the information can always be published, which is a deterrent for any fraud. The Aeternity state channels are integrated into the core of the block and do not require updating. This approach allows to preserve the integrity of the system from the first block to infinity, which will allow using this system to billions of people at the same time. This is a sensational decision! Aeternity http://www.aeternity.com/ also offers a number of applications (aepp-store) that can be used to create and apply in real world conditions, in many areas, based on smart contracts. In the future, thanks to free access to this platform, anyone can create their own application in the area of interest.

What is MERKLE TREE? What does MERKLE TREE mean? MERKLE TREE meaning & explanation

What is MERKLE TREE? What does MERKLE TREE mean? MERKLE TREE meaning - MERKLE TREE definition - MERKLE TREE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography and computer science, a hash tree or Merkle tree is a tree in which every non-leaf node is labelled with the hash of the labels or values (in case of leaves) of its child nodes. Hash trees allow efficient and secure verification of the contents of large data structures. Hash trees are a generalization of hash lists and hash chains. Demonstrating that a leaf node is a part of the given hash tree requires processing an amount of data proportional to the logarithm of the number of nodes of the tree; this contrasts with hash lists, where the amount is proportional to the number of nodes. The concept of hash trees is named after Ralph Merkle who patented it in 1979. A hash tree is a tree of hashes in which the leaves are hashes of data blocks in, for instance, a file or set of files. Nodes further up in the tree are the hashes of their respective children. For example, in the picture hash 0 is the result of hashing the concatenation of hash 0-0 and hash 0-1. That is, hash 0 = hash( hash 0-0 + hash 0-1 ) where + denotes concatenation. Most hash tree implementations are binary (two child nodes under each node) but they can just as well use many more child nodes under each node. Usually, a cryptographic hash function such as SHA-2 is used for the hashing. If the hash tree only needs to protect against unintentional damage, much less secure checksums such as CRCs can be used. In the top of a hash tree there is a top hash (or root hash or master hash). Before downloading a file on a p2p network, in most cases the top hash is acquired from a trusted source, for instance a friend or a web site that is known to have good recommendations of files to download. When the top hash is available, the hash tree can be received from any non-trusted source, like any peer in the p2p network. Then, the received hash tree is checked against the trusted top hash, and if the hash tree is damaged or fake, another hash tree from another source will be tried until the program finds one that matches the top hash. The main difference from a hash list is that one branch of the hash tree can be downloaded at a time and the integrity of each branch can be checked immediately, even though the whole tree is not available yet. For example, in the picture, the integrity of data block 2 can be verified immediately if the tree already contains hash 0-0 and hash 1 by hashing the data block and iteratively combining the result with hash 0-0 and then hash 1 and finally comparing the result with the top hash. Similarly, the integrity of data block 3 can be verified if the tree already has hash 1-1 and hash 0. This can be an advantage since it is efficient to split files up in very small data blocks so that only small blocks have to be re-downloaded if they get damaged. If the hashed file is very big, such a hash tree or hash list becomes fairly big. But if it is a tree, one small branch can be downloaded quickly, the integrity of the branch can be checked, and then the downloading of data blocks can start. The Merkle hash root does not indicate the tree depth, enabling a second-preimage attack in which an attacker creates a document other than the original that has the same Merkle hash root. For the example above, an attacker can create a new document containing two data blocks, where the first is hash 0-0 + hash 0-1, and the second is hash 1-0 + hash 1-1. One simple fix is defined in Certificate Transparency: when computing leaf node hashes, a 0x00 byte is prepended to the hash data, while 0x01 is prepended when computing internal node hashes. Limiting the hash tree size is a prerequisite of some formal security proofs, and helps in making some proofs tighter. Some implementations limit the tree depth using hash tree depth prefixes before hashes, so any extracted hash chain is defined to be valid only if the prefix decreases at each step and is still positive when the leaf is reached. The Tiger tree hash is a widely used form of hash tree. It uses a binary hash tree (two child nodes under each node), usually has a data block size of 1024 bytes and uses the Tiger hash. Tiger tree hashes are used in Gnutella, Gnutella2, and Direct Connect P2P file sharing protocols and in file sharing applications such as Phex, BearShare, LimeWire, Shareaza, DC++ and Valknut.

adsbook present's #Life changing income plan !!! The biggest investment Plan of 2017 Hurry up !! Dont miss the Oppertunity . Cryptocurrency Perfected Learn Why this Hybrid Solution will Trigger the Tipping Point of Cryptocurrency. LEARN MORE Link: https://netleaders.com/ref/aradhyosumon The Hybrid Solution And Why It’s Better DasCoin combines the best qualities of decentralized cryptocurrencies with the best aspects of centralized cryptocurrencies – and eliminates their weaknesses. Features CENTRALIZED EMISSIONS A fixed supply of coins are released as a reward for providing the necessary resources for a dedicated network to exist and expand. PERMISSIONED BLOCKCHAIN Only verified participants are enabled to transact in the ledger system, creating an atmosphere of integrity among users. DISTRIBUTED NETWORK All data travels across a global network of computers. DECENTRALIZED ECOSYSTEM The combination of blockchain and distributed network creates an autonomous ecosystem that offers integrity, security and performance. DYNAMIC PROVISIONING Additional infrastructure is automatically allocated to support network growth based on current demand levels. Dascoin coin INSTANT TRANSACTIONS Trades and transactions take place instantly and are non-repudiated providing maximum efficiency and integrity. ROBUST MARKETING The best of corporate marketing together with the best of decentralized affiliate marketing vastly extends interest and activity related to DasCoin. FRICTIONLESS EXCHANGE Dynamic fee generation based on bandwidth allocation results in no-cost and low cost transactions and world-class performance and scale. FULL COMPLIANCE Bank-level Know Your Client (KYC) and Anti-Money Laundering (AML) compliance creates a stable transactional environment of verified individuals. PRIVACY WITH TRANSPARENCY Identification content within all transactions recorded to the blockchain is obfuscated, providing privacy yet maintaining the integrity of the history of transactions. Benefits STABILITY The system is designed to optimize pricing stability. This is achieved through the calibrated manner in which DasCoins are emitted. Since the license packages are fixed in terms of price and amount of Cycles, as the network expands, the Frequency factor increases and this leads to an increase in the price of existing DasCoins. Consequently, pricing tends to slowly increase as the network grows and stabilize as the network reaches its full scale. SECURITY The power of the blockchain is foundational to the DasCoin system. A globally distributed database is used as a mutual ledger to document ownership of all DasCoins. It is maintained by authorized nodes that collect transactions and append them to the immutable ledger using modern cryptographic standards that enforce the integrity of all activities on the network. This forms what is known as a “permissioned blockchain” and is impervious to attack. SCALABILITY New DasCoins are distributed as the network successfully adds nodes to its infrastructure. The incentive of DasCoins results in resources becoming available when and where they are needed. Consequently, by linking provisioning to demand, the network is able to expand in direct proportion to the need for network services, making this model tremendously scalable. Dascoin features SUSTAINABILITY Resources for network growth are provided through the provisioning platform by individual licensees, and the network is able to maintain itself through its share of exchange fee revenue. The network delivers real-time transactions at virtually no cost, yet ensures that everyone is properly served. This is achieved by the measured way the network expands and how it intelligently monitors utilization. SIMPLICITY At the core of the currency is its simplicity and ease of use. DasCoin works closely with WebWallet to make the experience of transacting and trading with DasCoins as simple as possible. The digital wallet system incorporates a number of innovations aimed at providing a range of additional functionality through a very easy user interface, and conveniently available on your phone, tablet or laptop. Capture the rewards of being at the forefront of innovation. Maximize the opportunity for potential capital appreciation. Become a part of a global network that's reinventing money. Reap the rewards of sharing DasCoin with other people. Das Coin | Life changing income plan | Investment plan Of 2017 | Bangla

How Blockchain Technology is Changing Business
 
01:20:15
Sam Penfield, Advisory Product Manager at SAS and Joe Green, Associate Chair of the Department of Management and Entrepreneurship, provide an introduction to Blockchain technology and its impact on business. Blockchain was first described in 1991 by Stuart Haber and Scott Stornetta as a methodology to timestamp documents, and only became popular with the introduction of cryptocurrency in 2008. Blockchain technology promises a major disruption to well-established intermediaries including banks, insurance companies, and digital adverting corporations (e.g. Google). In this presentation we will explore what block technology is and how it is expected to change businesses moving forward. Sam Penfield is on a mission to connect, integrate, develop, build, architect solutions that combine SAS technologies, user driven requirements, open-source technologies, and external system amalgamation. With 20+ years’ experience as a consultant and 30+ years developing software Penfield has a true passion for programming languages and problem solving. Recently, Penfield has worked in an emerging technologies group helping with integrating Spark with SAS, prototyping SAS product enhancements and over the last 2+ years has focused on Blockchain technologies and the integration of SAS from a regulatory, data management, and real-time analytics perspective including AI and deep learning. Joe Green, in addition to his university responsibilities, maintains consulting engagements around Big Data; Enterprise Architecture; IT Strategy; and emerging technologies. Green has spent over fourteen years in senior leadership positions within financial services for Bank of America, Capital One, and Wells Fargo. In addition to financial services, he has served in consulting for the last five years with the following organizations: McKinsey & Company, SunTrust Banks, and J.P. Morgan. Currently, Green is serving on a three-year commitment on a joint task force student-level data (enrollment, degree, and course). This project will result in validating the SAT/ACT scores as an early indicator to college success and machine learning around factors of student success and post-graduation outcomes. Research is underway to allow students access to their comprehensive education record, which will be hosted through Blockchain technologies.

Brennan Novak: Secure Crypto for Browser Based Apps | JSConf EU 2014
 
16:48
Between Snowden’s NSA leaks prompting more secure communication and the rise of cryptocurrencies- software with secure cryptography as a core component is on the rise. Meanwhile, powerful applications written in JavaScript that render their UIs in a web browser are seeing unprecedented growth. However, if you ask most security researchers and developers about secure crypto in the browser, they’ll shake their heads skeptically. Reasons for this being: there are a lack of quality crypto primitives written in JavaScript that’ve been adequately reviewed and tested, JavaScript yields weak random number generation in all but the most recent HTML5 browsers, and secure key storage is difficult as the idiom du jour of web applications is to store user data on a remote server or in localStorage. This talk will explore how Mailpile, a Free / open source email client, is not vulnerable to these security concerns by shifting the attack surface out of the browser while still being a web application with a friendly JSON API. The gain being developers can leverage modern JavaScript libraries to render beautiful interfaces, animate fresh user interactions, and create compelling data visualziations. Want to make a force-directed graph of your inbox? JavaScript makes it easy, all while being extremely secure.

Emerging Technology Leadership Series: Brian Behlendorf and Blockchain
 
01:02:21
A recent report from the Organisation for Economic Co-operation and Development analyzed more than 200 government blockchain programs globally, a community that is rapidly growing as public services explore the immense potential of this emerging technology. In order to better learn about blockchain and evaluate solutions that improve transaction performance, traceability, and trust, public services must collaborate not just across silos between agencies, but side-by-side with the businesses, academic researchers, and organizations that are leading these advances. The Hyperledger Project, started in December 2015 by the Linux Foundation, is an open source initiative to support the collaborative development of blockchain-based distributed ledgers. In this first of our new Emerging Technology Leadership Series, we invite Brian Behlendorf, executive director of the Hyperledger Project and one of The New York Times’s “Top 10 People Leading the Blockchain Revolution,” answer your questions about collaborative development of blockchain solutions and share insights from the source on what public services need to know. The Emerging Technology Leadership Series, hosted by the U.S. General Services Administration (GSA) Emerging Citizen Technology Office, is a six-part livestream pilot to enhance the modern federal workforce with training, education, and awareness of emerging technologies including Artificial Intelligence, Robotic Process Automation, Blockchain, Social Technologies, and Virtual/Augmented Reality.

In India, a Son's Last Words: "These Policemen Will Kill Me"
 
02:53
Police in India often bypass arrest procedures and torture suspects in custody to death. At least 591 people died in police custody in India between 2010 and 2015, according to official data. One of these people, was Agnelo Valdaris, who died in police custody in 2014. Instead of holding police responsible to account, authorities have stalled reforms needed to build a more rights-respecting force.

Virtual Session: Blockchain Security: An Improvement or a Nightmare?
 
01:02:01
David Huseby, Security Maven, Linux Foundation Hyperledger Marta Piekarska, Director of Ecosystem, Linux Foundation Blockchain, the distributed ledger technology (DLT) underlying bitcoin, is far more valuable than the currency it supports. As enterprises start to put distributed ledger technology into practice, it’s important to understand the security implications. Blockchain can both enhance security but also when built into traditional solutions requires traditional security measures. In this RSAC Virtual Session from Linux Foundation’s David Huseby and Marta Piekarska, we’ll look at public vs. private blockchains and lessons learned for enterprises moving to DLTs. We'll walk through real life deployments of Blockchain solutions for an understanding of how Blockchain does, and does not, change the security requirements for your enterprise. https://www.rsaconference.com/videos/virtual-session-blockchain-security

CRYPTOCURRENCY - WikiVidi Documentary
 
17:54
A cryptocurrency is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets. Cryptocurrencies are a type of digital currencies, alternative currencies and virtual currencies. Cryptocurrencies use decentralized control as opposed to centralized electronic money and central banking systems. The decentralized control of each cryptocurrency works through a blockchain, which is a public transaction database, functioning as a distributed ledger. Bitcoin, created in 2009, was the first decentralized cryptocurrency. Since then, numerous other cryptocurrencies have been created. These are frequently called altcoins, as a blend of alternative coin.... http://www.wikividi.com ____________________________________ Shortcuts to chapters: 00:01:02: Overview 00:02:52: Blockchain 00:04:27: Timestamping 00:04:39: Proof-of-work schemes 00:05:08: Proof-of-stake and combined schemes 00:05:41: Mining 00:07:56: Wallets 00:08:19: Anonymity 00:09:00: Economics 00:09:31: Indices 00:09:43: Crypto index CRIX 00:10:32: CRYX Crypto Currencies Index 00:11:19: CCI30 Crypto Currencies Index 00:12:08: CRYX Cryptocurrency Volatility Index 00:12:35: CRYX Cryptocurrency Classification Standard 00:13:05: Transaction fees 00:14:00: Legality 00:14:42: U.S. tax status ____________________________________ Copyright WikiVidi.
