The World's Most Popular Algorithm: SHA 256 and Bitcoin
 
05:59
No one on Earth knows how to reverse the SHA-256 hash function. Yet it's really easy to compute one-way. You could make billions of dollars if you solved this mathematics problem. SHA-256 might also be the world's most popular algorithm - it's computed quintillions of times per second in the race for mining Bitcoin. It has some amazing properties, is useful for digital signatures, cryptography, authentication, and is a central part of the Bitcoin protocol. Bitcoin and other "crypto-currencies" rely on one-way hash functions like the SHA-256 algorithm to secure the blockchain where all the transactions are kept. In this video, I explain some of the big-picture ideas behind this one function. Other cryptocurrencies use similar ideas. Comments, suggestions, or errors? Let me know in the comments, and I'll fix them in an upcoming follow-up video (coming late July 2019) ---- Links ------ Wikipedia about SHA-256: https://en.wikipedia.org/wiki/SHA-2 Current Bitcoin difficulty: https://www.coinwarz.com/difficulty-charts/bitcoin-difficulty-chart Big number calculator: https://defuse.ca/big-number-calculator.htm ---- Credits ---- BitCoin & Money Photo: Copy Link to Credit: (CC-BY 4.0) Cryprocurrency360.com https://www.flickr.com/photos/bitcoin-crypto/41063960960 Bitcoin mining farm: (CC-BY 2.0) Marko Ahtisaari - https://www.flickr.com/photos/moia/ Fourier Transform Graph: (CC-BY 4.0) Jake http://pgfplots.net/tikz/examples/author/jake/ Wikipedia Hash Function Algorithm illustrations: https://en.wikipedia.org/wiki/SHA-2 (CC-BY-SA)

The Bitcoin and Blockchain Technology Explained
 
06:16
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?

BITCOIN MINING FARM MONGOLIA 👷🔨💰💸🤑💲
 
02:31
BITCOIN : What Is It and why Is It Important? Bitcoin‘s inventor, Satoshi Nakamoto, described Bitcoin as “A Peer-to-Peer Electronic Cash System” in the original 2009 Bitcoin whitepaper – the document which created the roadmap for Bitcoin. To date, this is still the most simple and accurate description. Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is perhaps best described as ‘cash for the Internet’, but Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence. It is also known as digital cash, cryptocurrency, an international payment network, the internet of money – but whatever you call it, Bitcoin is a revolution that is changing the way everyone sees and uses money. The beauty of Bitcoin is that it requires no central servers or third-party clearing houses to settle transactions – all payments are peer-to-peer (P2P) and are settled in about 10 minutes – unlike credit card payments, which can take weeks or months before they’re finally settled. All Bitcoin transactions are recorded permanently on a distributed ledger called the “blockchain” – this ledger is shared between all full Bitcoin “miners” and “nodes” around the world, and is publicly-viewable. These miners and nodes verify transactions and keep the network secure. For the electricity they use to do this, miners are rewarded with new bitcoins with each 10-minute block (the reward is currently 12.5 BTC per block). The Bitcoin protocol is also hard-limited to 21 million bitcoins, meaning that no more than that can ever be created. This means that no central bank, individual or government can come along and simply ‘print’ more bitcoins when it suits them. In this sense Bitcoin is a deflationary currency, and as such is likely to grow in value based on this property alone. Bitcoin is still a cutting-edge experiment in technology and economics, and like the worldwide web in 1995, its myriad potential, purposes and applications are yet to be decided. Is it just electronic money? A foundation for smart contracts and electronic shares? Is it underground and subversive, challenging the power of governments, or will it integrate into mainstream finance and go unnoticed? If you know the answers to any of these questions, or if you can figure out how to capitalize on them there may be many lucrative opportunities for you in the Bitcoin space.

Narration --------------------------------------------------------------------------------- What is Bitcoin worth? - Part 1 Disclaimer! Do not base any financial decision in your life on stuff I say in a YouTube video. Seriously! Do your own due diligence, be skeptical and take responsibility for your decisions. And read the paper that I based this video on yourself. Note that is also has a disclaimer. No, bitcoin is not backed by anything. So how can it be worth anything? Well, that’s what we want to find out. Are bitcoin and other cryptos like ethereum going to be worth anything in the long run? … assuming of course they are successful AT ALL! Any of them could totally fail and be worth nothing any day for a bunch of different reasons. Let’s start by categorizing crypto tokens into 2 categories: Network backbone / Virtual Machine (for example Ethereum) (basically all the “blockchain” stuff) and Money First let’s look at the first which we could call “utility protocols” Think of them kind of like distributed data centers. Instead of having a bunch of servers in a big warehouse somewhere like Amazon Web Services or Google’s version of that, you use the processing power, memory and bandwidth of a bunch of computers all across the world. Those computers are called miners and they have real world costs for hardware and electricity. And in exchange they get block rewards and/or transaction fees. So let’s look at that network as if it was an entire economy. The cost of the processing power, memory and bandwidth would be the GDP and the network token would be the money of this economy that is used to pay for those resources. So the value of those two things would be equal. M all the money equal P x Q, the price of a unit of each resource times the quantity of it … oh and don’t forget: … divided by V the velocity of money, a variable that tells us how frequently a token is used and reused on our network. So the value of one token is M/T. That is the value of all of the tokens divided by the number of tokens. Basically, in the long run, the total value of all the tokens won’t be more than the total cost of all of the resources on the network and each token will be worth the respective fraction of that. Why? Well, valid question! Say the tokens are trading for more than that amount that’s necessary to compensate the miners, the network will be used only for the highest value use cases until either the token price drops to the efficient amount, or someone makes an identical copy of it (a so called fork) where the token price is closer to that efficient amount. In all cases the token price ends up at that price that’s just enough to compensate the miners for their costs in the long run. And that number (M/T) could be decreasing Right now a lot of the resources on those networks are used for proof of work, but in the near future that can probably be replaced by leaner consensus mechanisms. And a bunch of other technologies (proof of stake, sharding, Segregated Witness, Lightning Network, Plasma, Raiden) are being developed to make the networks use less resources. Also the price of the real world hardware will probably continue to decrease, just like you can each year get a computer with more memory and CPU and perks for the same price. If those things happen P times Q will decrease. The tokens can be transacted really quickly online, that could mean that V could be really high. Smaller P times Q and a larger V would mean smaller M, which would make M/T smaller, which is our token value. That’s it for now, but there are 3 more parts to come. So bye for now and ‘till the next part!

Omni Layer –  Protocol, Cryptocurrency, Review, Description
 
02:37
Omni Layer (formerly Mastercoin) is one of several efforts to enable complex financial functions in a cryptocurrency. Planned features include the development of a decentralized Omni exchange and the implementation of smart property and savings wallets. «A common analogy that is used to describe the relation of the Omni Layer to bitcoin is that of HTTP to TCP/IP: HTTP, like the Omni Layer, is the application layer to the more fundamental transport and internet layer of TCP/IP, like bitcoin».Omni Layer coin, the initiative to build a protocol layer over the Bitcoin blockchain and other systems, is a pretty intense project. The software allows users to transact with tokens with asset representations. Omni has so many versatile uses that it provides a cryptocurrency asset landscape in this environment. The omni omni asset, being the first to be introduced in this network, is close to completion. Bitcoin and various cryptocurrencies act as a base layer of usage; the Omni project is a higher layer and a benchmark for asset protocols. Omni is a protocol built as a layer over Bitcoin that allows you to generate, send, trade, redeem, pay dividends to and make bets with tokens representing any kind of asset. The OMNI asset is the first asset on the layer, it gets the fees from the layer’s trustless exchange, and it can transform into any currency using smart contracts on the layer. Instead of just sending bitcoins around, you can send a very small amount of bitcoin that acts like a stamp, and that transaction forever stands for the transfer of some Omni layer property. Several projects have raised money in crowdsales by issuing tokens or app-coins over the layer, there’s a dollar coin, Tether USDT, backed by the same banks that Bitfinex uses and integrated with the deposit/withdrawal systems of Bitfinex, Cryptsy, and several other exchanges, and that’s just the start.

The Cryptoeconomic Properties of Bitcoin
 
07:14
The Cryptoeconomic Properties of Bitcoin - https://blockgeeks.com/ The term “cryptoeconomics” causes a lot of confusion. People are often unclear on what it is supposed to mean. The word itself can be misleading, as it suggests that there is a parallel “crypto” version of the whole of economics. This is wrong. In simple terms, cryptoeconomics is the use of incentives and cryptography to design new kinds of systems, applications, and networks. Cryptoeconomics is specifically about building things. Cryptoeconomics is not a subfield of economics, but rather an area of applied cryptography that takes economic incentives and economic theory into account. Bitcoin, ethereum, zcash and all other public blockchains are products of cryptoeconomics. To understand why the coins on these blockchains have value, we first need to understand what money really is and what makes it valuable. In the most basic sense, money facilitates trade. In earlier societies, money could be a bag of flour, a fur hide, or even a goat. It could be anything, as long as the person receiving it deemed it valuable enough to provide a good or service for it in return. For hundreds of years people traded goods and services directly, and money as we understand it today didn’t exist. Let’s say I have a farm with an excess supply of wheat. I could offer a bag of wheat to the local shoemaker for a pair of shoes. For this transaction to happen, I need to want shoes, and the shoemaker needs to want wheat. But what if the shoemaker doesn’t want wheat? Or I had a bad harvest and don’t have enough wheat to spare? If I don’t have something the shoemaker wants, I can’t use his services. This was a real problem. Different people needed different things at different times, so no one could guarantee that they had the required items to make a successful trade for even the most basic amenities they needed to survive, like food or warm clothing. People needed something that was valuable to everyone all the time. So instead, they started trading coins with each other that acted as placeholders for value. And what made these coins special was that everyone agreed they had the same value. This gave people the guarantee they needed: they could always trade coins for any good or service, which made them want to collect more and more coins, because the more coins you had, the more things you could trade them for. Fast forward a few hundred years, and you can see the basic premise of money hasn’t changed much. We all agree on what a dollar is worth, and each of us has a certain number of dollars, which we use to get goods and services. We also provide goods and services to get more dollars. The only thing that makes our dollars valuable is that we know we can use them to get things. That, and the fact that we can’t just magically produce them whenever we want. So for money to have value, everyone needs to agree to give it value, and it has to be scarce. So how does Bitcoin achieve this? Bitcoin’s promise of a decentralized currency is very valuable. It functions like digital cash - it has all the convenience and speed of digitally transferring money, without having to rely on a third party like a bank. These properties, as well as the security in the network that ensures they can be fulfilled, makes Bitcoin something people want to assign value to. With bitcoin, you can send money across the world in minutes, without having to worry about exchanging currencies or going through intermediary banks. You also know that your bitcoins have value on an international level. So you’re not tied to your bank, or your particular country per se. Some of the biggest markets for bitcoins are in countries like Greece or Venezuela, where their national currency’s value is very unstable. With Bitcoin, people in these countries know that their assets won’t suddenly become worthless when their national economy takes a hit. This is an offer people find very appealing, because it goes a step further to give your assets value on the international market and facilitates direct trade on a global scale. Other tech companies tried to come up with digital cash couldn’t get around the problem of trust. To read more, check out https://blockgeeks.com/

Benno Luthiger - Bitcoin and Blockchain for Pythoneers
 
28:47
"Bitcoin and Blockchain for Pythoneers [EuroPython 2017 - Talk - 2017-07-10 - Anfiteatro 1] [Rimini, Italy] Why should a Python programmer be interested in Bitcoin and the Blockchain technology? Blockchain technology is one of the fastest moving part in the Fintech area. However, the Blockchain is not only the basis of crypto currencies. First of all it’s a decentralized registry that cannot be modified. This means that using a Blockchain, users can trust in the validity of a dataset without the need to establish a central authority. Thus, the Blockchain can be used to store records e.g. of land ownership or and other property rights in countries with weak or corrupt or otherwise incompetent authorities. Therefore, Python programmers with an understanding of this technology are especially well prepared to contribute in this area, because the agility inherent to Python makes it easy to program in a fast moving environment. The fact that various applications in the Bitcoin and Blockchain area are implemented in Python prove this notion. However, the reverse is also true: An understanding of the distributed ledger technology possibly enables you to solve problems in projects you encounter in the near future. In this talk, I will present the following topics: • The Blockchain architecture: nodes, transactions, headers. • The Bitcoin protocol and its proof of work (POW) • Smart contracts • Bitcoin alternatives: Proof-of-work (PoW) compared to Proof-of-stake (PoS) License: This video is licensed under the CC BY-NC-SA 3.0 license: https://creativecommons.org/licenses/by-nc-sa/3.0/ Please see our speaker release agreement for details: https://ep2017.europython.eu/en/speaker-release-agreement/

What is The History of Bitcoin: Super Easy Explanation
 
12:11
What is The History of Bitcoin: Super Easy Explanation - https://blockgeeks.com/ We’ll start at the very beginning by understanding the history of blockchain. The very first blockchain in the world was Bitcoin. An anonymous person or group known as Satoshi Nakamoto published a document in an online cryptography forum in November 2008 and revealed the first details of how it would work, describing it as a “peer-to-peer electronic cash system”. The whitepaper is available today at bitcoin.org/bitcoin.pdf. It allows any 2 people to pseudonymously send money to each other no matter where they are in the world. It is a borderless currency. The main benefit of Bitcoin is that it does not require any centralized authority or institution to operate. This is in contrast to today’s centralized financial systems that depend on the existence of a central bank or government to mint money. If for any reason the central authority were to shutdown, the money would become worthless. In a decentralized system like Bitcoin, there is no central authority and the system can continue to operate as long as there are members in its peer-to-peer network. The goal of the whitepaper was to describe how the different parts of the Bitcoin protocol would operate and be kept secure. A new type of database, called a blockchain, would keep track of a single history of all Bitcoin transactions and it would be maintained by everyone in the network. The database would be publicly available for anyone to view and inspect, and anyone can download a copy of the same database. This provides data redundancy and makes sure the data is never lost, but also provides a way for anyone to verify the transactions in the database themselves. A block in the database just stores a sequence of transactions, and a sequence of blocks is called a blockchain. Each block is identified by an incrementing number and a unique Sha-256 hash. The hash for a block is calculated using the transactions inside it, as well as the previous block’s hash, which forms a chain of hashes. The data in the blocks is secured using a cryptographic algorithm called proof-of-work, which also keeps all members of the network and the database in sync to prevent double-spending. In this context, preventing double-spending means preventing anyone from spending money they dont have. Proof-of-work is used to generate new blocks for the database, also known as mining, and the reward for mining a new block is given to the miner by creating new Bitcoins in the system. This is the only way new Bitcoins can be created. Anyone on the network can be a miner and a new block is mined roughly every 10 minutes, which includes the latest set of verified transactions. The first release for Bitcoin was version 0.1 written in C++ by Satoshi and published on SourceForge in January 2009 under the open-source MIT license. Anyone could download the source code and run it to join the network, also known as becoming a node in the network. This is the original version 0.1 source code written by Satoshi. We can see the hard-coded genesis block, which is the very first block in the chain. The hash for the block can be verified by using any Bitcoin blockchain explorer. Let’s copy and paste this hash into the blockchain explorer available at blockchain.info. We can see that this hash is for block number 0, and that it has only one transaction in it which is the mining reward, and the reward amount of 50 Bitcoin was given to this Bitcoin address. We can also see this 50 Bitcoin reward for the genesis block in the original source code. The genesis block is a special case needed to start the blockchain and is the only block that is hard-coded, whereas every subsequent block is calculated using proof-of-work. Satoshi’s motivation for creating Bitcoin is revealed in the piece of data he included in the genesis block: a newspaper headline from The Times that read ‘Chancellor on brink of second bailout for banks’. The date of the newspaper is proof that the genesis block was created on or after Jan 3 2009. Satoshi developed the source code mostly himself up until mid-2010, when he handed it off to the open-source community. It is now maintained under the project called Bitcoin Core. The software is currently at version 0.15.1 and is available for download at bitcoin.org. This is still the most popular Bitcoin client, and its estimated that there are over 10 thousand nodes running the Bitcoin network today using various clients. Satoshi disappeared from public view in late 2010, his identity still unknown to this day. The only way someone could prove that they are Satoshi is by using the same encryption keys used when posting the original whitepaper in the online cryptography forum.

Travala. Spend Crypto. Get Rewards. #1 NEO dAPP. 30+ Crypto Payments For Travel and More!
 
25:56
This space is full of many projects who have promised to put out functioning products. Most of those promises have failed. One project, Travala, has fulfilled that promise and more. Travala has put out a user-friendly travel booking marketplace that connects consumers with vendors, booking wholesalers, and booking aggregators directly together over the platform. This product has been live since March of 2018. Travala has been improving the platform ever since. The most recent update includes the ability to book a hotel or property with over 30 cryptocurrencies. Of course Travala tokens are accepted, but also NEO, GAS, Bitcoin, Litecoin, Ripple XRP, Binance Coin, Dash, 0x, Dogecoin, and many others. Fiat payments will be coming soon as well. Over 567,000 properties are offered, making it one of the robust blockchain travel ecosystems in existence.

Blockchain 101 Ep 47 - What is a Timestamp?
 
00:59
Timestamps show that the blocks are connected in a chronological order. It marks the time for each transaction on the blockchain. Simply put, the timestamp proves when and what has happened on the blockchain, and it’s tamper-proof. Timestamp plays to role of a notary, and it’s more credible than a traditional one. Because nobody can alter the information on the blockchain. Given the timestamp feature, blockchain technology is suitable for areas such as intellectual property protection. For instance, when you have written a thesis, You want to consult an industry expert before publishing, but you are afraid the expert might steal your work. Under such a scenario, you only need to save it on the blockchain to easily prove your ownership over the article.

Bitcoin -- more than just money | Dug Campbell | TEDxUniversityofEdinburgh
 
16:47
This talk was given at a local TEDx event, produced independently of the TED Conferences. Dug Campbell explains why Bitcoin is not just the money of the Internet, but it’s the Internet of money. He has been avidly following the impact of technology on society since the late 90’s and he’s convinced that the cat’s out of the bag when it comes to digital currency. As well as working as Product Marketing Manager at Skyscanner, he writes on how digital networks continue to influence the modern world. Oh, and he’s pretty sure the robots are coming, but doesn’t want to give an exact date. About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Bitcoin, Payment Security, and Consumer Protection
 
01:08:59
A lecture by Andreas M. Antonopoulos on bitcoin's security as a payment mechanism, compared to credit cards. This talk was delivered on November 24th 2014 at the Melbourne Tech Center in Melbourne, Australia. 31:58 - 38:50 The future of bitcoin in the contractual space i.e. smart contracts. Using more complicated scripts (time-locked, multi-signature, multi-party). Internet of Things and smart property. The authentication system in unlocking cars. Transferring ownership. 38:52 - 44:42 Bitcoin the currency, Bitcoin the technology, Bitcoin the network. The technology doesn't work without a viable "currency." It takes a certain momentum of adoption. Money is a language we use to express value. Conditions to investing in bitcoin. Investing in skills, education, services. 44:50 - 50:45 Centralised services stripping away privacy. Stop re-centralising our decentralised system! Game theory. Greek mythology, creating stories to describe technology. 50:45 - 56:03 Silk Road and Mt Gox. Technological innovation is always accompanied by negativity. Sensationalism leads. I don't know any form of money which can't be used to buy drugs. You can't get stabbed over TCP/IP. Deal with the root causes (healthcare, addiction), don't try to stop the free flow of money. Charitable donations and tipping. +1:03:17 - 1:08:21 To regulators: wait and understand before you act. Custodial control. The Bitcoin network cannot be regulated. 56:07 - 1:03:16 How I discovered Bitcoin, "nerd money." Every good advocate started as a skeptic. Mainstream adoption. In the Western world, you have to explain the 'why' of Bitcoin; in the developing world, you just need to explain the 'how.'

BitCoin | What is Bitcoin | How to Buy Bitcoin and Trade in India? Paisa Double ? Hindi
 
10:03
Disclaimer : SkillTune & Team holds no responsibility for BitCoin trade / Price Control,Invest on your own Risk. Bitcoin: What Is It and why Is It Important? Bitcoin‘s inventor, Satoshi Nakamoto, described Bitcoin as “A Peer-to-Peer Electronic Cash System” in the original 2009 Bitcoin whitepaper – the document which created the roadmap for Bitcoin. To date, this is still the most simple and accurate description. Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is perhaps best described as ‘cash for the Internet’, but Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence. It is also known as digital cash, cryptocurrency, an international payment network, the internet of money – but whatever you call it, Bitcoin is a revolution that is changing the way everyone sees and uses money. The beauty of Bitcoin is that it requires no central servers or third-party clearing houses to settle transactions – all payments are peer-to-peer (P2P) and are settled in about 10 minutes – unlike credit card payments, which can take weeks or months before they’re finally settled. The Bitcoin protocol is also hard-limited to 21 million bitcoins, meaning that no more than that can ever be created. This means that no central bank, individual or government can come along and simply ‘print’ more bitcoins when it suits them. In this sense Bitcoin is a deflationary currency, and as such is likely to grow in value based on this property alone. How Can You Buy Bitcoin? Bitcoins can be bought from various sources. You can purchase them online using an exchange or brokerage service that will enable you to buy Bitcoin with a bank transfer using fiat currency, a credit card, and some services also offer buying opportunities using Paypal. Bitcoin can also be purchased locally using LocalBitcoins, and from Bitcoin Teller Machines which are similar to cash ATMs that you find worldwide. When did Bitcoin start? History. Bitcoin was created by Satoshi Nakamoto, who published the invention on 31 October 2008 to a cryptography mailing list in a research paper called "Bitcoin: A Peer-to-Peer Electronic Cash System". It was implemented as open source code and released in January 2009. How new bitcoins are created? New bitcoins are generated by a competitive and decentralized process called "mining". This process involves that individuals are rewarded by the network for their services. Bitcoin miners are processing transactions and securing the network using specialized hardware and are collecting new bitcoins in exchange. What is bit coin used for? As you've noted, Bitcoin is a digital currency used to pay for a variety of goods and services. ... Although physical forms of Bitcoin exist, the currency's primary form is data so you trade it online, peer to peer, using wallet software or an online service What is meant by digital currency? Digital currency can be defined as an Internet-based form of currency or medium of exchange distinct from physical (such as banknotes and coins) that exhibits properties similar to physical currencies, but allows for instantaneous transactions and borderless transfer-of-ownership How much was a Bitcoin worth in 2009? Guy named Koch bought 5,000 bitcoins in 2009 for $27, now worth $886,000. Talk about a degree that gives you bang for your buck. Kristoffer Koch was writing a thesis on encryption in 2009 when he spent about $27 to buy 5,000 bitcoins How does a Cryptocurrency work? A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency. Cryptocurrencies are a subset of alternative currencies, or specifically of digital currencies.

HOW TO WITHDRAW STELLAR LUMENS (XLM) FROM BINANCE EXCHANGE TO WALLET | BITCOIN | ALTCOIN | CRYPTOCURRENCY 2018 Hey everyone! In today's edition of Altcoin News, you will learn how to withdraw your Stellar Lumens (XLM) coins from the Binance exchange to your wallet. --- Don't forget to subscribe, like, & leave a comment! :D --- Learn how to create a Stellar Lumens (XLM) wallet: https://youtu.be/HXU1rU9y2Wk Learn how to send Stellar Lumens (XLM) to an exchange: https://youtu.be/vkVBurAuz_o --- Subscribe for more: http://bit.ly/Subscribe2AltcoinNews --- Stellar is an open-source protocol for value exchange founded in early 2014 by Jed McCaleb (creator of eDonkey) and Joyce Kim. Its board members and advisory board members include Keith Rabois, Patrick Collison, Matt Mullenweg, Greg Stein, Joi Ito, Sam Altman, Naval Ravikant and others. The Stellar protocol is supported by a nonprofit, the Stellar Development Foundation. --- Stellar is an open-source protocol for exchanging money. Servers run a software implementation of the protocol, and use the Internet to connect to and communicate with other Stellar servers, forming a global value exchange network. Each server stores a record of all “accounts” on the network. These records are stored in a database called the “ledger”. Servers propose changes to the ledger by proposing “transactions”, which move accounts from one state to another by spending the account’s balance or changing a property of the account. All of the servers come to agreement on which set of transactions to apply to the current ledger through a process called “consensus”. The consensus process happens at a regular interval, typically every 2 to 4 seconds. This keeps each server’s copy of the ledger in sync and identical. --- --- Buy Bitcoin, Ethereum and Litecoin on Coinbase: http://bit.ly/AltcoinGeniusCoinbase --- Buy and Trade Altcoins on Binance: http://bit.ly/AltcoinGeniusBinance --- Connect with me on Social Media! :D (PS): Turn notifications on! :) --- Subscribe on Youtube: http://bit.ly/AltcoinNewsYoutube Follow me on Instagram: http://bit.ly/AltcoinGeniusInstagram Follow me on Twitter: http://bit.ly/AltcoinGeniusTwitter Like my Facebook Page: http://bit.ly/AltcoinNewsFacebook Join the EXCLUSIVE FB GROUP: http://bit.ly/AltcoinGeniusFBGroup Follow me on Soundcloud: http://bit.ly/AltcoinNewsSoundcloud Follow me on Tumblr: http://bit.ly/AltcoinGeniustumblr Follow me on Steemit: http://bit.ly/AltcoinGeniusSteemit Follow me on DTube: http://bit.ly/AltcoinGeniusDTube Add me on Snapchat: http://bit.ly/JF420 Website http://www.secrethustlingtips.com --- BTC 16VXesem45Wi7YA3mjtKQiTQzrJrL8HBmp ETH 0x45BE97126B419Fc20eD6951f91e2Ba6Ea571A9d9 LTC LQ3czdWR4A3yovJmjnq9vb1kLtKHrhi3H8 Stellar GD7LCN2SZ7FGACAJKHI7O4ZBQJ43UAJUJETXZFFWEJ3WHK7N46ETJRPC ---------- Disclaimer: Statements on this site do not represent the views or policies of anyone other than myself.

Prof. Kiayias - Ouroboros - A Provably Secure Proof of Stake Blockchain Protocol, CARDANO
 
57:30
https://iohk.io/research/papers/a-pro... Mathematicians with a curiosity about the algorithms behind blockchain came to hear Aggelos Kiayias speak at Oxford university’s Mathematical Institute on Wednesday. Professor Kiayias, Chief Scientist at IOHK, had been invited to the university to give a talk on his work on Ouroboros, a provably secure Proof-of-Stake algorithm for blockchain. It the first time such a cryptographic protocol has been devised and is significant because its use would enable blockchains to process many more transactions, giving the technology the muscle that would scale it up for far wider use than at present. “Bitcoin is slow,” he said in the presentation, in an outline of the problem. “The transactions per second of Visa are in the order of many thousands, for Paypal in the order of hundreds, and Bitcoin is far less than that – clearly that’s something that can’t scale to a global level.” In addition to the much greater efficiency of Ouroboros, Prof Kiayias explained a novel reward mechanism for incentivising the protocol and used game theory to show why attacks such as selfish mining and block withholding would be neutralised. A Nash equilibrium is a prescription of a strategy for each rational player, with the property that if other players follow it, it does not make sense for a rational player to deviate from it. Prof Kiayias described how Ouroboros can be proven to be an approximate Nash equilibrium, thus distinguishing this blockchain system from Bitcoin, which is known to be not incentive compatible. The Ouroboros paper was first published last December with Alexander Russel, Bernardo David and Roman Oliynykov and Prof Kiayias presented the work at the Alan Turing Institute in London last year. Bernardo David on PoS: https://www.youtube.com/watch?v=q5sCs... Bernardo David presenting PoS in detail at IOHK's Tokyo tech lab: https://youtu.be/hMgxZOsTlQc Among the audience was Hayyu Imanda, whose desire to specialise in cryptography for her PhD studies brought her to hear the presentation. The 22-year-old is currently in a class of 26 students at Oxford university studying for an MSc in Mathematics and Foundations of Computer Science. “I come from a pure maths background and I find cryptography very interesting, in that it was relatively recently founded and there is so much research happening,” she says. “I see it as a bridge from pure maths into real life, with many uses in terms of security, and it’s going to be a growing field.” More images from the event here: https://iohk.io/blog/a-proof-of-stake... -- https://iohk.io/team/aggelos-kiayias/ Prof Aggelos Kiayias is the Chair in Cyber Security and Privacy at the University of Edinburgh. His research interests are in computer security, information security, applied cryptography and foundations of cryptography with a particular emphasis in blockchain technologies and distributed systems, e-voting and secure multiparty protocols as well as privacy and identity management. He joins IOHK as chief scientist through a long-term consulting agreement between IOHK and the University of Edinburgh, UK, where he is based and continues to do research and teach courses in cyber security and cryptography. Prof Kiayias is also Professor in Residence (gratis) at the University of Connecticut, USA, and Associate Professor of Cryptography and Security (on leave) at the National and Kapodistrian University of Athens, Greece. Prof Kiayias’s cyber security research over the years has been funded by the Horizon 2020 programme (EU), the European Research Council (EU), the General Secretariat for Research and Technology (Greece), the National Science Foundation (USA), the Department of Homeland Security (USA), and the National Institute of Standards and Technology (USA). He has received an ERC Starting Grant, a Marie Curie fellowship, an NSF Career Award, and a Fulbright Fellowship. He holds a Ph.D. from the City University of New York and he is a graduate of the Department of Mathematics at the University of Athens. He has more than 100 publications in journals and conference proceedings in the area.

Matematyczne podstawy Bitcoina oraz systemy e-voting
 
02:09:00
Gościnny wykład poprowadzony przez profesora Mariana Srebrnego z Instytutu Podstaw Informatyki PAN. Bitcoin Technology - Selected Basic Details & A New End-To-End Verifiable Internet-Voting Protocol ABSTRACT This talk will be a brief presentation of the landscape of the most important and most interesting issues and events focused on Bitcoin protocol design/cryptanalysis: the bitcoin story – e-gold, computational workload complexity, the main hero: cryptographic hash functions, proof-of-work concept, no trusted third party, collective/multiparty authority, public ledger of all transactions, of bitcoin technology: addresses/accounts, coin mining, transactions, e-signatures, incentives, majority consensus decisions, et cetera. The second part of this talk is motivated by the famous recent mishaps of Facebook. By way of response from the cryptographic community, we will focus on trust, network security, and privacy deployed in parallel and distributed systems. Those issues are of crucial importance these days because various tasks are allocated to, and information is exchanged among the system devices that may belong to different users. It will highlight recent advances in trust, security, and privacy for emerging parallel and distributed systems. We’ll present a new design of a protocol of End-to-End Verifiable e-voting over the Internet, intended for a rather small group of voters. A particular emphasis in our e-voting protocol is on a guarantee that each voter can efficiently verify if her vote is adequately recorded, as cast, and counted in the tally, as recorded. The procedure avoids sabotage, tampering or forging, due to conceivable faked hardware or software. The second important property of the protocol is that no voter can prove whom she has voted for. This eliminates, or at least essentially restricts, the possibility of coercion, buying or selling the votes. Technically, the protocol is based on secret sharing methods, multi-party computation, and modular arithmetic with the Chinese Remainder Theorem, and it uses blockchain technique with collective distributed Satoshi cosensus.

GENESIS BITCOIN MINING FARM
 
06:34
BITCOIN : What Is It and why Is It Important? Bitcoin‘s inventor, Satoshi Nakamoto, described Bitcoin as “A Peer-to-Peer Electronic Cash System” in the original 2009 Bitcoin whitepaper – the document which created the roadmap for Bitcoin. To date, this is still the most simple and accurate description. Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is perhaps best described as ‘cash for the Internet’, but Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence. It is also known as digital cash, cryptocurrency, an international payment network, the internet of money – but whatever you call it, Bitcoin is a revolution that is changing the way everyone sees and uses money. The beauty of Bitcoin is that it requires no central servers or third-party clearing houses to settle transactions – all payments are peer-to-peer (P2P) and are settled in about 10 minutes – unlike credit card payments, which can take weeks or months before they’re finally settled. All Bitcoin transactions are recorded permanently on a distributed ledger called the “blockchain” – this ledger is shared between all full Bitcoin “miners” and “nodes” around the world, and is publicly-viewable. These miners and nodes verify transactions and keep the network secure. For the electricity they use to do this, miners are rewarded with new bitcoins with each 10-minute block (the reward is currently 12.5 BTC per block). The Bitcoin protocol is also hard-limited to 21 million bitcoins, meaning that no more than that can ever be created. This means that no central bank, individual or government can come along and simply ‘print’ more bitcoins when it suits them. In this sense Bitcoin is a deflationary currency, and as such is likely to grow in value based on this property alone. Bitcoin is still a cutting-edge experiment in technology and economics, and like the worldwide web in 1995, its myriad potential, purposes and applications are yet to be decided. Is it just electronic money? A foundation for smart contracts and electronic shares? Is it underground and subversive, challenging the power of governments, or will it integrate into mainstream finance and go unnoticed? If you know the answers to any of these questions, or if you can figure out how to capitalize on them there may be many lucrative opportunities for you in the Bitcoin space.

What is bitcoin?

What is Bitcoin? It is also known as digital cash, cryptocurrency, an international payment network, the internet of money – but whatever you call it, Bitcoin is a revolution that is changing the way everyone sees and uses money. The beauty of Bitcoin is that it requires no central servers or third-party clearing houses to settle transactions – all payments are peer-to-peer (P2P) and are settled in about 10 minutes – unlike credit card payments, which can take weeks or months before they’re finally settled. All Bitcoin transactions are recorded permanently on a distributed ledger called the “blockchain” – this ledger is shared between all full Bitcoin “miners” and “nodes” around the world, and is publicly-viewable. These miners and nodes verify transactions and keep the network secure. For the electricity they use to do this, miners are rewarded with new bitcoins with each 10-minute block (the reward is currently 12.5 BTC per block). The Bitcoin protocol is also hard-limited to 21 million bitcoins, meaning that no more than that can ever be created. This means that no central bank, individual or government can come along and simply ‘print’ more bitcoins when it suits them. In this sense Bitcoin is a deflationary currency, and as such is likely to grow in value based on this property alone. What are its characteristics? Bitcoin has several important features that set it apart from government-backed currencies. 1. It's decentralized The bitcoin network isn’t controlled by one central authority. Every machine that mines bitcoin and processes transactions makes up a part of the network, and the machines work together. That means that, in theory, one central authority can’t tinker with monetary policy and cause a meltdown – or simply decide to take people’s bitcoins away from them, as the Central European Bank decided to doin Cyprus in early 2013. And if some part of the network goes offline for some reason, the money keeps on flowing. 2. It's easy to set up Conventional banks make you jump through hoops simply to open a bank account. Setting up merchant accounts for payment is another Kafkaesque task, beset by bureaucracy. However, you can set up a bitcoin address in seconds, no questions asked, and with no fees payable. 3. It's anonymous Well, kind of. Users can hold multiple bitcoin addresses, and they aren’t linked to names, addresses, or other personally identifying information. However… 4. It's completely transparent …bitcoin stores details of every single transaction that ever happened in the network in a huge version of a general ledger, called the blockchain. The blockchain tells all. If you have a publicly used bitcoin address, anyone can tell how many bitcoins are stored at that address. They just don’t know that it’s yours. There are measures that people can take to make their activities more opaque on the bitcoin network, though, such as not using the same bitcoin addresses consistently, and not transferring lots of bitcoin to a single address. 5. Transaction fees are miniscule Your bank may charge you a £10 fee for international transfers. Bitcoin doesn’t. 6. It’s fast You can send money anywhere and it will arrive minutes later, as soon as the bitcoin network processes the payment. 7. It’s non-repudiable When your bitcoins are sent, there’s no getting them back, unless the recipient returns them to you. They’re gone forever. https://www.bitcoin.com/info/bitcoin-what-is-it-and-why-is-it-important https://en.wikipedia.org/wiki/Bitcoin Do you already have bitcoins?

Alex Tapscott: "Blockchain Revolution" | Talks at Google
 
56:39
Talks at Google in London were delighted to welcome Alex Tapscott to talk about his book Blockchain Revolution, looking at how the technology behind Bitcoin can reshape the world of business and transform the old order of human affairs for the better. Alex can be found on Twitter at: @alextapscott Book on Google Play - with free first chapter! https://play.google.com/store/books/details/Don_Tapscott_Blockchain_Revolution?id=bwz_CwAAQBAJ About the Book: The technology likely to have the greatest impact on the future of the world economy has arrived, and it's not self-driving cars, solar energy, or artificial intelligence. It’s called the blockchain. The first generation of the digital revolution brought us the Internet of information. The second generation powered by blockchain technology is bringing us the Internet of value: a new, distributed platform that can help us reshape the world of business and transform the old order of human affairs for the better. Blockchain is the ingeniously simple, revolutionary protocol that allows transactions to be simultaneously anonymous and secure by maintaining a tamperproof public ledger of value. Though it's the technology that drives bitcoin and other digital currencies, the underlying framework has the potential to go far beyond these and record virtually everything of value to humankind, from birth and death certificates to insurance claims and even votes. Why should you care? Maybe you're a music lover who wants artists to make a living off their art. And those examples are barely the tip of the iceberg. This technology is public, encrypted, and readily available for anyone to use. It's already seeing widespread adoption in a number of areas. For example, forty-two (and counting) of the world's biggest financial institutions, including Goldman Sachs, JPMorgan Chase, and Credit Suisse, have formed a consortium to investigate the blockchain for speedier and more secure transactions. As with major paradigm shifts that preceded it, the blockchain will create winners and losers. And while opportunities abound, the risks of disruption and dislocation must not be ignored. About the Author: Alex Tapscott is the CEO and Founder of Northwest Passage Ventures, an advisory firm building industry-leading blockchain businesses. Formerly, Alex was a senior executive at Canaccord Genuity, Canada’s largest independent investment bank. At age 25, he became the firm’s youngest-ever Vice President and in 2014, he founded the firm’s blockchain practice. Over his career, Alex has worked tirelessly for his clients, raising hundreds of millions of dollars in growth capital from a global institutional investor base, and provided sound advice and counsel.

At least I hope you have a lot of questions, it’s good if you do, it means you’re a critical thinker. There’s lots to be weary of in the crypto space and the more questions you ask the easier it will be to come to your own conclusions. After all, if you decide to invest your money, it’s just that, YOUR money. Be smart, educate yourself and if I were to give any investment advice it would be this: invest in coins or projects that you believe in and want to support, invest in projects, that in your opinion, provide real solutions. Okay, so I’d like to address some commonly asked questions that are aimed at Bitcoin, but really, they apply to most cryptocurrencies. First, what are the benefits to Bitcoin or cryptocurrencies? * Freedom - This means that bitcoin and alt coins enable you to send and receive any amount of money instantly anywhere in the world at any time. No bank holidays. No borders. No imposed limits. They allows users to be in full control of their money. * Fewer risks for merchants - Transactions are secure, irreversible, and do not contain customers’ sensitive or personal information. This protects merchants from losses caused by fraud or fraudulent chargebacks. The net results are lower fees, larger markets, and fewer administrative costs. * Security and control - Users of crypto are in full control of their transactions; it is impossible for merchants to force unwanted or unnoticed charges as can happen with other payment methods. Payments can be made without personal information tied to the transaction. This offers strong protection against identity theft. Not to mention the fact that users can also protect their money with backup and encryption. * Transparent and neutral - All information concerning the money supply itself is readily available on the blockchain for anybody to verify and use in real-time. No individual or organization can control or manipulate the protocol because it is cryptographically secure. This allows for trust in being completely neutral, transparent and predictable. Now what are the downsides to Bitcoin or other cryptocurrencies? * Degree of acceptance - Many people are still unaware of Bitcoin and even less so of other cryptocurrencies. Every day, more businesses accept bitcoins because they want the advantages of doing so, but the list remains small and still needs to grow in order to benefit from network effects. * Volatility - The total value of bitcoins in circulation and the number of businesses using Bitcoin are still very small compared to what they could be. Therefore, relatively small events, trades, or business activities can significantly affect the price. In theory, this volatility will decrease as the technology matures and Bitcoin interest rates normalize. Never before has the world seen a start-up currency, so it is truly difficult (and exciting) to imagine how it will play out. Why do bitcoins have value? Bitcoins have value because they are useful as a form of money. Bitcoin and altcoins have the characteristics of money like: (durability, portability, fungibility, scarcity, divisibility, and recognizability) based on the properties of mathematics rather than relying on physical properties (like gold and silver) or trust in central authorities (like fiat currencies). all that is required for a form of money to hold value is trust and adoption. In the case of Bitcoin, this can be measured by its growing base of users, merchants, and startups. As with all currency, bitcoin's value comes only and directly from people willing to accept them as payment. Additional Reading: https://www.weusecoins.com/en/questions/

BITCOIN : What Is It and why Is It Important? Bitcoin‘s inventor, Satoshi Nakamoto, described Bitcoin as “A Peer-to-Peer Electronic Cash System” in the original 2009 Bitcoin whitepaper – the document which created the roadmap for Bitcoin. To date, this is still the most simple and accurate description. Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is perhaps best described as ‘cash for the Internet’, but Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence. It is also known as digital cash, cryptocurrency, an international payment network, the internet of money – but whatever you call it, Bitcoin is a revolution that is changing the way everyone sees and uses money. The beauty of Bitcoin is that it requires no central servers or third-party clearing houses to settle transactions – all payments are peer-to-peer (P2P) and are settled in about 10 minutes – unlike credit card payments, which can take weeks or months before they’re finally settled. All Bitcoin transactions are recorded permanently on a distributed ledger called the “blockchain” – this ledger is shared between all full Bitcoin “miners” and “nodes” around the world, and is publicly-viewable. These miners and nodes verify transactions and keep the network secure. For the electricity they use to do this, miners are rewarded with new bitcoins with each 10-minute block (the reward is currently 12.5 BTC per block). The Bitcoin protocol is also hard-limited to 21 million bitcoins, meaning that no more than that can ever be created. This means that no central bank, individual or government can come along and simply ‘print’ more bitcoins when it suits them. In this sense Bitcoin is a deflationary currency, and as such is likely to grow in value based on this property alone. Bitcoin is still a cutting-edge experiment in technology and economics, and like the worldwide web in 1995, its myriad potential, purposes and applications are yet to be decided. Is it just electronic money? A foundation for smart contracts and electronic shares? Is it underground and subversive, challenging the power of governments, or will it integrate into mainstream finance and go unnoticed? If you know the answers to any of these questions, or if you can figure out how to capitalize on them there may be many lucrative opportunities for you in the Bitcoin space.

Monero (XMR): Private Cryptocurrency Payments & Anonymous Coin Transactions?
 
02:58
Read All About Monero XMR: https://www.mybitcoin.com/monero-xmr/ Monero was launched in 2014 as a privacy coin named BitMonero, The name was shortened to simply Monero a few days later. The core team of Monero is comprised of 7 developers, 5 of whom remain anonymous. David Latapie and Riccardo Spagni are the two publicly known developers. Based on the egalitarian CryptoNight proof-of-work algorithm derived from the CryptoNote application layer protocol, Monero aims to offer greater privacy and decentralization than Bitcoin. There are currently close to 16 million Monero is circulation with a daily emission rate of roughly 3000 coins. A monero block is mined every 2 minutes. Monero does not have a fixed maximum supply like Bitcoin. Once the circulating supply reaches 18 million, the daily emission rate will stay fixed at 432 coins. The core principles of Monero are privacy, ASIC resistance and a flexible protocol which allows for seamless implementation of new features. Whereas in Bitcoin, transaction details, sending and receiving addresses are transparent and viewable by anyone, Monero obscures these details using an I2P overlay network, Stealth addresses, Ring Signatures and Ring Confidential Transactions. I2P is a network layer with strong privacy protection and prevents surveillance and monitoring by third parties such as network service providers. Stealth address is a feature in Monero which requires the sender to create a one-time address for a transaction on behalf of the recipient. Using stealth addresses allows only the sender and receiver to know where a payment was sent. Ring Signature uses multiple public keys from the blockchain to create a transaction output, making the public key belonging to the actual sender untraceable. Monero's fungibility is a property allowing units of a currency to be interchangeable. Fungibility also makes it impossible for units of Monero to be blacklisted by exchanges, vendors and service providers. Ring Confidential Transactions(RingCT), implemented in January 2017, is a feature used to hide transaction amounts. RingCT is an upgraded version of Ring Signature called multi-layered linkable spontaneous anonymous group signature. Put simply, it allows the sender's transaction to be verified without disclosing the amount being spent. Monero performed a network upgrade via consensual hard fork in March 2018 to introduce two major changes. First, a tweak of the PoW algorithm to ward off the threat of CryptoNight ASIC miners and secondly, an increase of minimum ring size from 6 to 7. Ring size is the total number of signers in a ring signature, including the sender. Android GUI port, subaddresses and Multi-signatures are on the agenda for future development.

Zerocash: Addressing Bitcoin's Privacy Problem
 
01:18:45
A Google TechTalk, 8/28/17, presented by Alessandro Chiesa Abstract: In Bitcoin, a payment's details are broadcast in the clear, so that anyone can verify its validity. Unfortunately, this violates user privacy and sacrifices coin fungibility. I will describe the Zerocash protocol, which uses zero knowledge proofs to achieve privacy-preserving payments in a Bitcoin-like system. This protocol was recently deployed in the wild, as part of the cryptocurrency Zcash. About the Speaker: Alessandro Chiesa is an assistant professor in the Department of Electrical Engineering and Computer Science at UC Berkeley. His research spans the areas of complexity theory, cryptography, and security, and focuses on the theoretical foundations and practical implementations of cryptographic proof systems such as zero knowledge proofs. He is a co-inventor of Zerocash and co-founder of Zcash. He is an author of libsnark, the leading open-source library for succinct zero knowledge proofs. He has received a Ph.D. in computer science from MIT in 2014, and B.S. degrees in computer science and in mathematics from MIT in 2009.

what is bitcoin Explain in Hindi
 
04:42
Bitcoin is a form of digital currency, created and held electronically. No one controls it. Bitcoins aren’t printed, like dollars or euros – they’re produced by people, and increasingly businesses, running computers all around the world, using software that solves mathematical problems.It’s the first example of a growing category of money known as cryptocurrency. What makes it different from normal currencies? Bitcoin can be used to buy things electronically. In that sense, it’s like conventional dollars, euros, or yen, which are also traded digitally. However, bitcoin’s most important characteristic, and the thing that makes it different to conventional money, is that it is decentralized. No single institution controls the bitcoin network. This puts some people at ease, because it means that a large bank can’t control their money. Who created it? A software developer called Satoshi Nakamoto proposed bitcoin, which was an electronic payment system based on mathematical proof. The idea was to produce a currency independent of any central authority, transferable electronically, more or less instantly, with very low transaction fees. Who prints it? No one. This currency isn’t physically printed in the shadows by a central bank, unaccountable to the population, and making its own rules. Those banks can simply produce more money to cover the national debt, thus devaluing their currency. Instead, bitcoin is created digitally, by a community of people that anyone can join. Bitcoins are ‘mined’, using computing power in a distributed network. This network also processes transactionsmade with the virtual currency, effectively making bitcoin its own payment network. So you can’t churn out unlimited bitcoins? That’s right. The bitcoin protocol – the rules that make bitcoin work – say that only 21 million bitcoins can ever be created by miners. However, these coins can be divided into smaller parts (the smallest divisible amount is one hundred millionth of a bitcoin and is called a ‘Satoshi’, after the founder of bitcoin). What is bitcoin based on? Conventional currency has been based on gold or silver. Theoretically, you knew that if you handed over a dollar at the bank, you could get some gold back (although this didn’t actually work in practice). But bitcoin isn’t based on gold; it’s based on mathematics. Around the world, people are using software programs that follow a mathematical formula to produce bitcoins. The mathematical formula is freely available, so that anyone can check it. The software is also open source, meaning that anyone can look at it to make sure that it does what it is supposed to. What are its characteristics? Bitcoin has several important features that set it apart from government-backed currencies. 1. It's decentralized The bitcoin network isn’t controlled by one central authority. Every machine that mines bitcoin and processes transactions makes up a part of the network, and the machines work together. That means that, in theory, one central authority can’t tinker with monetary policy and cause a meltdown – or simply decide to take people’s bitcoins away from them, as the Central European Bank decided to do in Cyprus in early 2013. And if some part of the network goes offline for some reason, the money keeps on flowing. 2. It's easy to set up Conventional banks make you jump through hoops simply to open a bank account. Setting up merchant accounts for payment is another Kafkaesque task, beset by bureaucracy. However, you can set up a bitcoin address in seconds, no questions asked, and with no fees payable. 3. It's anonymous Well, kind of. Users can hold multiple bitcoin addresses, and they aren’t linked to names, addresses, or other personally identifying information. However… 4. It's completely transparent …bitcoin stores details of every single transaction that ever happened in the network in a huge version of a general ledger, called the blockchain. The blockchaintells all. If you have a publicly used bitcoin address, anyone can tell how many bitcoins are stored at that address. They just don’t know that it’s yours. There are measures that people can take to make their activities more opaque on the bitcoin network, though, such as not using the same bitcoin addresses consistently, and not transferring lots of bitcoin to a single address. 5. Transaction fees are miniscule Your bank may charge you a £10 fee for international transfers. Bitcoin doesn’t. 6. It’s fast You can send money anywhere and it will arrive minutes later, as soon as the bitcoin network processes the payment. In next video I will show how to buy and sell bitcoin.. content idea given by Technical Monster youtube channel. https://m.youtube.com/user/231yash Thumbnail Designed by Tech Faux

Bitcoin Q&A: The value of proof-of-work
 
14:30
Can a blockchain exist without miners, proof-of-work, or blocks? What are the implications for security, trustlessness, and decentralisation? Not all distributed ledgers are blockchains. What is the influence of alternative energy generation on mining in proof-of-work cryptocurrencies? Should we use alternative algorithms that generate "useful work" in addition to mining cryptocurrencies? The hard promises that Bitcoin provides are valuable and useful in themselves. What is the difference between proof-of-work and proof-of-stake? Note: These sessions were recorded live using Google Hangouts. The audio and video may be slightly out of sync at some points. These questions are from the MOOC sessions 7.2 and 8.2, covering the Byzantine Generals' Problem, which took place on February 26th 2017 and September 15th 2017 respectively. Andreas is a teaching fellow with the University of Nicosia.
