Consensus and Mining on the Blockchain
 
08:03
Consensus and Mining on the Blockchain - https://blockgeeks.com/ What is consensus on the blockchain? Consensus basically means that all nodes in a decentralized network must come to an agreement on what is the truth. For bitcoin, all nodes must agree on the transaction history. In a centralized system, all the participants trust that the authority will behave honestly and share the truth with the rest of the members. Since only the trusted party has the power to modify the data, it is straightforward to achieve consensus. Everyone simply accepts and believes what the central authority says. For example, you simply trust your bank will put the correct balance for your account whenever you send and receive money. However, in a decentralized network, there is no central authority and each node does not trust any other nodes. The challenge is how can all the nodes agree on what is the correct state of the shared data? In other words, how can they all achieve consensus with mutual distrust? In computer science, this is known as the Byzantine Generals’ problem, which was originally presented in 1982. The Byzantine Generals’ problem is a description of consensus problems in computer networks. More specifically, how can distributed computer systems handle malfunctioning parts that give conflicting information to different parts of the system? This problem is abstractly described as a group of generals of the Byzantine army camped with their troops surrounding an enemy city. The generals must agree upon a common battle plan and they can only communicate with each other using messengers. However, one or more of the generals may be traitors who will try to confuse the others. The problem is to find an algorithm that ensures the loyal generals will all reach an agreement on the battle plan regardless of what the traitors do. In the case of bitcoin, each general could be thought of as a node in the network and all the honest nodes must agree on what is the true history of transactions. A malicious node can send conflicting transactions to different parts of the network. For example, Bob is a traitor and he sends a transaction stating he sent 10 bitcoins to Alice to one part of the network while sending another transaction stating he sent 10 bitcoins to Carroll to other parts of the network. Let’s assume that Bob only has 10 bitcoins in total, so he is trying to double spend his bitcoins. So what algorithm can be used in the bitcoin network to ensure all the honest nodes recognize Bob sent 10 bitcoins to Alice but reject that he sent 10 bitcoins to Carroll? Bitcoin uses the proof-of-work (PoW) algorithm to ensure all the honest nodes reach a consensus on the true history of transactions. The PoW algorithm concept was first developed in the early 90s to prevent email spamming. It required computers that want to send an email to do some computation work which took some time to complete before sending out the email. This reduced the amount of spam an email server could get in a given period of time. In bitcoin, PoW is used to govern the mechanics of how a new block is added to the blockchain. In the previous lesson, we learned that blockchain is append-only and once a block is added, it cannot be modified. Therefore, we need to ensure that all the honest nodes in the system will add the exact same block to their local copy of the blockchain to achieve consensus. So how does PoW achieve this? First, let’s imagine that all the nodes in the network are allowed to create a new block at anytime instantly. If this were the case, the network would get flooded with too many new blocks, and no one would be able to agree on which of the new blocks should be added to the blockchain. However, in reality, in order for a node to create a new block and broadcast that to the other nodes, it must do some computation work. The computation work is quite intensive and for bitcoin it takes roughly 10 minutes on average for any node to complete. Once a node completes this work, it broadcasts the block to other nodes who verify it. Therefore, all the nodes in the network that want to create a new block must race against each other to be the first one to complete this computation and broadcast their block. This way all the other honest nodes will receive the new block and verify that the proof of work was valid and the transactions inside the block are also correct and then add the block to their local copy of the blockchain.

And also allow for alt coins and Bitcoin to scale- Remember Lightning Network? They could also one day allow for cryptos to interact with each other, thus opening the door for so many possibilities. Understanding Blockstream: https://thecontrol.co/understanding-blockstream-25af2b6f0084 So Blockstream funds the development of Bitcoin Core, which is the main Bitcoin network client software. Blockstream is a blockchain technology company that also boasts itself as being the originator of side chains. Whether or not that’s true, they were at least one of the first and still a major player that is pursuing this big idea. https://blog.blockchain.com/tag/blockstream/ Let’s break down what a sidechain is. In laymen’s terms, sidechains run parallel to a main blockchain, like bitcoin’s blockchain for example. They use a two-way peg, meaning you can move your bitcoin from the main bitcoin blockchain, to the sidechain, and then back again. This is done by essentially locking away your bitcoin from the main blockchain while it is in use on the sidechain, and they are then released once you prove they are no longer being used on the sidechain. The first side chain is called Elements Alpha. It’s a tesnet where developers can utilize the open source code to contribute to the project and discover ways to improve the bitcoin blockchain. Other projects for side chain implementations include the likes of Rootstock. The developers at Rootstock, or RSK have announced at consensus 2017 the release of Ginger, which is their open sourced testnet. Ginger is aimed at providing more functionality to the Bitcoin Network like smart contracts, increased scalability and a new revenue stream for miners. http://media.rsk.co/rsk-announces-the-global-release-of-ginger-the-open-source-testnet/ https://www.cryptocompare.com/coins/guides/what-is-rootstock/ As always in crypto land, it’s not always sunshine and roses, there are still some kinks to work out with side chains until they can be considered ideal. One of the arguable weak points of sidechains is the fact that federations are a select few who ultimately call the shots and determine if/when the coins you use between the main blockchain and the sidechain are locked up and released. This is a centralization of the whole system, and whoever is behind the sidechain will determine who is included in its federation. Trusting a dozen or so individuals to authorize all transactions can be seen as a major security flaw. One other weak point is the fact that sidechains will need it’s own miners. This could pose a problem when considering that these miners will need to be monetarily incentivized. One way to fix this is by implementing merge mining. T his is the process of allowing two different crypto currencies based on the same algorithm to be mined simultaneously. It allows low hash powered crypto currencies to increase the hashing power behind their network by bootstrapping onto more popular crypto currencies. https://www.cryptocompare.com/mining/guides/what-is-merged-mining-bitcoin-namecoin-litecoin-dogecoin/ I’m sure that there are Bitcoin maximalists out there who see this development of side chains for Bitcoin as a nail in the coffin for Ethereum. Because sidechains have the potential to provide Bitcoin with the ability to integrate smart contracts, this does seem to take an edge away from Ethereum in terms of services provided. However, I will always believe in the robust development team behind Ethereum and their ability to work together to constantly produce innovative new projects. So don’t say goodnight to Ethereum. Instead, I’d like you to consider how side chains can open the door for different cryptocurrencies to work together and take advantage of their strengths.

Blockchain tutorial 3: Hash
 
05:09
This is part 3 of the Blockchain tutorial explaining what hashes are. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

Basically, the way that Proof of Stake works, and what gives it its name, is the miners are required to hold a certain amount of the coin in their wallet, or stake, in order to qualify to mine for new blocks. These qualified miners are then randomly selected to be able to mine the next new block and receive the new coins that are in it. Contrast this with how Proof of Work miners are all competing to unlock the next new block, using lots of energy to do so, and it’s easy to see how Proof of Stake is more efficient. Similar to Proof of Work and how different networks use different hash algorithms, the staking rewards and staking mechanisms differ for Proof of Stake networks as well. We have yet to achieve perfection in this world of cryptocurrencies. There will always be pros and cons to each system. The problem with Proof of Work is ash it takes a lot of computing power, and therefore a lot of energy to run the network and maintain the blockchain. In fact, it is this requirement for this large amount of computer power that acts as the security measure against any one entity being able to control the network (51% attacks)  This was especially true before things like mining pools were created. But that’s something to be saved for another post. There are many pros and cons for Proof of Work, but for the purposes of this video, here are a few: Pros: * More decentralized network * More secure network Cons: * Requires large amounts of energy * Wasted computing power Proof of Stake is at least a more energy efficient way to essentially accomplish the same goals. However, there are a few hang ups for this system as well. Proof of Stake limits who is able to help secure the network by requiring miners to hold a certain amount of its coins in their wallet. Some Proof of Stake coins have been pre-mined, and some have even been “significantly pre-mined" meaning the individuals who created the coin were able to mine coins before going public. This can very easily result in whales, or individuals who hold large amounts of a coin, who then qualify to run a large number of staking nodes. A network that is already less decentralized thanks to this minimum coin requirement, could end up with a few wealthy individuals who would ultimately be able to control the network by running a majority of the staking nodes. Pros: * More energy efficient * Better rewards for staking your coins Cons: * Less decentralized network * less secure network Proof of Stake is an advancement of the idea behind Proof of Work, and with it often comes other mechanisms that work to provide other services that enhance how the network runs. These are called Masternodes and if done correctly, they can be a way to earn a passive income. I’ll be covering masternodes and how to find affordable options in my next video so if this is something you’re interested in learning more about be sure to subscribe to this channel and hit that bell icon to get notified when that video is released.

How secure is 256 bit security?
 
05:06
Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Thread for Q&A questions: http://3b1b.co/questions Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives a desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

Bitcoin Cash Explained ( BTC vs BCH )
 
08:04
Bitcoin Cash was launched in August 2017 and since become Bitcoin’s most popular cryptocurrency that has forked from bitcoin network. The reason of this fork is to increase the block size and process more transaction per second. Bitcoin’s maximum block capacity is 1MB, at this current time allows to process 3-7 transactions per second and implications of congested blocks, means paying high fees. Bitcoin’s cash on other hand maximum block capacity is 8MB witch is allowed to process around 60 transactions per second and fees 99% cheaper than original bitcoin. ================================================== 💰Get a Coinbase Wallet! - https://www.coinbase.com/join/5a4bf25...

What is CRYPTOGRAPHIC NONCE? What does CRYPTOGRAPHIC NONCE mean? CRYPTOGRAPHIC NONCE meaning

What is CRYPTOGRAPHIC NONCE? What does CRYPTOGRAPHIC NONCE mean? CRYPTOGRAPHIC NONCE meaning - CRYPTOGRAPHIC NONCE definition - CRYPTOGRAPHIC NONCE 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, a nonce is an arbitrary number that may only be used once. It is similar in spirit to a nonce word, hence the name. It is often a random or pseudo-random number issued in an authentication protocol to ensure that old communications cannot be reused in replay attacks. They can also be useful as initialization vectors and in cryptographic hash function. A nonce is an arbitrary number used only once in a cryptographic communication, in the spirit of a nonce word. They are often random or pseudo-random numbers. Many nonces also include a timestamp to ensure exact timeliness, though this requires clock synchronization between organizations. The addition of a client nonce ("cnonce") helps to improve the security in some ways as implemented in digest access authentication. To ensure that a nonce is used only once, it should be time-variant (including a suitably fine-grained timestamp in its value), or generated with enough random bits to ensure a probabilistically insignificant chance of repeating a previously generated value. Some authors define pseudo-randomness (or unpredictability) as a requirement for a nonce. Authentication protocols may use nonces to ensure that old communications cannot be reused in replay attacks. For instance, nonces are used in HTTP digest access authentication to calculate an MD5 digest of the password. The nonces are different each time the 401 authentication challenge response code is presented, thus making replay attacks virtually impossible. The scenario of ordering products over the Internet can provide an example of the usefulness of nonces in replay attacks. An attacker could take the encrypted information and—without needing to decrypt—could continue to send a particular order to the supplier, thereby ordering products over and over again under the same name and purchase information. The nonce is used to give 'originality' to a given message so that if the company receives any other orders from the same person with the same nonce, it will discard those as invalid orders. A nonce may be used to ensure security for a stream cipher. Where the same key is used for more than one message and then a different nonce is used to ensure that the keystream is different for different messages encrypted with that key; often the message number is used. Secret nonce values are used by the Lamport signature scheme as a signer-side secret which can be selectively revealed for comparison to public hashes for signature creation and verification. Initialization vectors may be referred to as nonces, as they are typically random or pseudo-random. Nonces are used in proof-of-work systems to vary the input to a cryptographic hash function so as to obtain a hash for a certain input that fulfills certain arbitrary conditions. In doing so, it becomes far more difficult to create a "desirable" hash than to verify it, shifting the burden of work onto one side of a transaction or system. For example, proof of work, using hash functions, was considered as a means to combat email spam by forcing email senders to find a hash value for the email (which included a timestamp to prevent pre-computation of useful hashes for later use) that had an arbitrary number of leading zeroes, by hashing the same input with a large number of nonce values until a "desirable" hash was obtained. Similarly, the bitcoin block-chain hashing algorithm can be tuned to an arbitrary difficulty by changing the required minimum/maximum value of the hash so that the number of bitcoins awarded for new blocks does not increase linearly with increased network computation power as new users join. This is likewise achieved by forcing bitcoin miners to add nonce values to the value being hashed to change the hash algorithm output. Because cryptographic hash algorithms cannot easily be predicted based on their inputs, this makes the act of blockchain hashing and the possibility of being awarded bitcoins something of a lottery, where the first "miner" to find a nonce that delivers a desirable hash is awarded valuable bitcoins.

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.

Blockchain/Bitcoin for beginners 9: Bitcoin difficulty, target, BITS  - all you need to know
 
48:16
In this video I break the somewhat confusing and mysterious question of how exactly the block difficulty is defined, represented and updated. There is a simplification/misconception that the requirement is just to find a hash with a required number of leading zeros in hex. This is not the case, it's a little more intricate than that.... I show some examples of real blocks - in particular focusing on the genesis block, and how import it is for initializing the difficulty of mining a block. I clarify the relationship between BITS (in the block header) difficulty, and the actual 256 hash target.

Litecoin & Bitcoin: What's the Difference?!

If you’re looking for an app that tracks the price of BTC & ETH and many other coins, check out the CoinView App: https://play.google.com/store/apps/de… LINKS FOR ADDITIONAL READING FOR THIS VIDEO & ALL INFO IN TEXT DOWN BELOW Litecoin Scrypt Mining:https://cryptovest.com/education/litecoin-mining-scrypt-algorithm-for-a-leading-coin/ ASIC Scrypt Miners: https://www.ehsminer.com/product/ehs-asic-scrypt-miner-vi/ Charts on Top Cryptos: https://bitinfocharts.com/ Bitcoin has open source code, meaning it’s open to the public to analyze and learn from. This has inspired a whole lot of people to take this code and tweak it in a way that they think will be most beneficial, resulting in a new cryptocurrency and blockchain. One of the first of these people is Charlie Lee. So right off the bat, Litecoin has a publicly identified creator compared to the anonymous Satoshi Nakamoto. Charlie created Litecoin about two years after Bitcoin. And one of the ways that he chose to make Litecoin different is how Litecoin is mined. Litecoin uses Scrypt mining. This type of mining can be thought of as ASIC resistant, meaning that it requires memory in addition to computing power, which is what GPUs are much better suited for. Litecoin was designed this way to purposely avoid the centralization we’re now seeing with Bitcoin and it’s mining pools. Scrypt mining is still profitable for those who want to use their computers, unlike Bitcoin at this point. But you know how those ASIC manufacturers like to innovate, there are ASICs for Scrypt mining now as well. Regardless, this helps explain one aspect of how Litecoin can implement changes much faster and easier than Bitcoin. Litecoin doesn’t have these huge, centralized mining farms like Bitcoin which have enough control over the network, like Antpool that allows them to strongly influence decisions like hard forks. Bitcoins trouble with reaching consensus in regards to updates to the network can also be attributed to the sheer size of the network. Bottom line, Bitcoin has a lot of miners and nodes that need to come together and choose to signal one way or another. Decentralization is great, and although we are increasingly becoming accustomed to instant gratification, this slow process of updates can actually help make sure that major mistakes aren’t made, and that the network has had ample time to consider the pros and cons. This is when Litecoin comes into play and can demonstrate how things like Segregated Witness and Lightning Network can work once implemented. Litecoin often comes to decisions much faster because the network is generally smaller, with less developers and not as many powerful stakeholders (like blockstream) than Bitcoin, it’s easier for Litecoin to make decisions faster. In addition to all of this, there are also some economic differences between Bitcoin and Litecoin. For example, the total possible supply of Litecoin is 84 million compared to the 21 million of Bitcoin. This sets the stage for overall more coins for Litecoin’s block rewards, and a less expensive price tag per coin. Generally, the Litecoin network sees a bit more 10% of the amount of transactions compared to Bitcoin. The block times are a fraction of Bitcoin as well, which translates to faster transactions. Getting back to the mining aspect of Litecoin, the difficulty and hash rates are lower so mining is actually more directly profitable for Litecoin.

What is Hashing & Digital Signature in The Blockchain?
 
06:19
What is Hashing & Digital Signature in The Blockchain? https://blockgeeks.com/ Today, we're going to be talking about the word blockchain and breaking it down to understand what does it mean when someone says, "Blockchain." What is hashing? Hashing refers to the concept of taking an arbitrary amount of input data, applying some algorithm to it, and generating a fixed-size output data called the hash. The input can be any number of bits that could represent a single character, an MP3 file, an entire novel, a spreadsheet of your banking history, or even the entire Internet. The point is that the input can be infinitely big. The hashing algorithm [00:01:00] can be chosen depending on your needs and there are many publicly available hashing algorithms. The point is that the algorithm takes the infinite input of bits, applies some calculations to them, and outputs a finite number of bits. For example, 256 bits. What can this hash be used for? A common usage for hashes today is to fingerprint files, also known as check zones. This means that a hash is used to verify that a file has not been [00:01:30] tampered with or modified in any way not intended by the author. If WikiLeaks, for example, publishes a set of files along with their MD5 hashes, whoever downloads those files can verify that they are actually from WikiLeaks by calculating the MD5 hash of the downloaded files, and if the hash doesn't match what was published by WikiLeaks, then you know that the file has been modified in some way. How does the blockchain make use of hashes? [00:02:00] Hashes are used in blockchains to represent the current state of the world. The input is the entire state of the blockchain, meaning all the transactions that have taken place so far and the resulting output hash represents the current state of the blockchain. The hash is used to agree between all parties that the world state is one in the same, but how are these hashes actually calculated? The first hash is calculated for the first block [00:02:30] or the Genesis block using the transactions inside that block. The sequence of initial transactions is used to calculate a block hash for the Genesis block. For every new block that is generated afterwords, the previous block's hash is also used, as well as its own transactions, as input to determine its block hash. This is how a chain of blocks is formed, each new block hash pointing to the block hash that came before it. This system of hashing guarantees that no transaction in the history can be tampered with because if any single part of the transaction changes, so does the hash of the block to which it belongs, and any following blocks' hashes as a result. It would be fairly easy to catch any tampering as a result because you can just compare the hashes. This is cool because everyone on the blockchain only needs to agree on 256 bits to represent the potentially infinite state of the blockchain. The Ethereum blockchain is currently tens of gigabytes, but the current state of the blockchain, as of this recording, is this hexadecimal hash representing 256 bits. What about digital signatures? Digital signatures, like real signatures, are a way to prove that somebody is who they say they are, except that we use cryptography or math, which is more secure than handwritten signatures that can be [00:04:00] easily forged. A digital signature is a way to prove that a message originates from a specific person and no one else, like a hacker. Digital signatures are used today all over the Internet. Whenever you visit a website over ACTPS, you are using SSL, which uses digital signatures to establish trust between you and the server. This means that when you visit Facebook.com, your browser can check the digital signature that came with the web page to verify that it indeed originated from Facebook and not some hacker. In asymmetric encryption systems, users generate something called a key pair, which is a public key and a private key using some known algorithm. The public key and private key are associated with each other through some mathematical relationship. The public key is meant to be distributed publicly to serve as an address to receive messages from other users, like an IP address or home address. The private key is meant to be kept secret and is used to digitally sign messages sent to other users. The signature is included with the message so that the recipient can verify using the sender's public key. This way, the recipient can be sure that only the sender could have sent this message. Generating a key pair is analogous to creating an account on the blockchain, but without having to actually register anywhere. Pretty cool. Also, every transaction that is executed on the blockchain is digitally signed by the sender using their private key. This signature ensures that only the owner of the account can move money out of the account.

At its simplest, Ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications. Is Ethereum similar to Bitcoin? Well, sort of, but not really. Like Bitcoin, Ethereum is a distributed public blockchain network. Although there are some significant technical differences between the two, the most important distinction to note is that Bitcoin and Ethereum differ substantially in purpose and capability. Bitcoin offers one particular application of blockchain technology, a peer to peer electronic cash system that enables online Bitcoin payments. While the bitcoin blockchain is used to track ownership of digital currency (bitcoins), the Ethereum blockchain focuses on running the programming code of any decentralized application. In the Ethereum blockchain, instead of mining for bitcoin, miners work to earn Ether, a type of crypto token that fuels the network. Beyond a tradeable cryptocurrency, Ether is also used by application developers to pay for transaction fees and services on the Ethereum network. “Bitcoin is first and foremost a currency; this is one particular application of a blockchain. However, it is far from the only application. To take a past example of a similar situation, e-mail is one particular use of the internet, and for sure helped popularise it, but there are many others.” Dr Gavin Wood, Ethereum Co-Founder What is a smart contract? Smart contract is just a phrase used to describe computer code that can facilitate the exchange of money, content, property, shares, or anything of value. When run on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Because smart contracts run on the blockchain, they run exactly as programmed without any possibility of censorship, downtime, fraud or third party interference.

Bitcoin Q&A: Energy consumption
 
05:51
Is the "energy consumption" in mining a problem? Mining is a business of arbitrage for the cheapest sources of electricity. Proof-of-work mining is contributing to massive investment and subsidy in renewables / alternative energy and efficiency improvements in processing. It is driving the decentralization of energy production. "Consumption" in Bitcoin is easy to criticize because it is obvious, whereas the hidden externalities of the traditional financial system are massive.

What is Bitcoin? How to Mine Bitcoin? [ Bangla Video]
 
07:13
What is Bitcoin? With the Bitcoin price so volatile everyone is curious. Bitcoin, the category creator of blockchain technology, is the World Wide Ledger yet extremely complicated and no one definition fully encapsulates it. By analogy it is like being able to send a gold coin via email. It is a consensus network that enables a new payment system and a completely digital money. How many bitcoins are there? When the algorithm was created under the pseudonym Satoshi Nakamoto—which in Japanese is as common a name as Steve Smith—the individual(s) set a finite limit on the number of bitcoins that will ever exist: 21 million. Currently, more than 12 million are in circulation. That means that a little less than 9 million bitcoins are waiting to be discovered. কি ভাবে রেফার প্রোগ্রাম করবেন দেখুন - https://youtu.be/F2tZtDDAdiU কি ভাবে ফেসবুক থেকে ইনকাম করবেন - https://youtu.be/qGOJjV-WiRc কি ভাবে বিটকয়েন ইনকাম করবেন - https://youtu.be/k5s3mmG3vNg কি ভাবে ওজো ওয়েব থেকে ইনকাম করবেন - https://youtu.be/uguLWe9-DAk কি ভাবে সরেট লিঙ্ক করে ইনকাম করবেন - https://youtu.be/vGmp_qSbgvE Thanks for watching …..

Proof-of-Work (PoW) vs. Proof-of-Stake (PoS)
 
09:43
Proof of work vs proof of stake explained! Here's a simplified explanation on how a PoW blockchain differs from PoS, and how it applies to Bitcoin. 4. The Byzantine Generals’ Problem Before I begin discussing proof-of-work, it’s important for you to be aware of the Byzantine Generals’ Problem, also known as the Byzantine Fault Tolerance. 3. Proof-of-work Proof-of-work is a computational protocol miners use to validate transactions in a cryptocurrency network & add the transaction to the blockchain. Put simply, miners use their computers to churn through a ton of different guesses until the computer comes up with the right answer that fits within the network’s required parameters. Different cryptocurrencies use different mathematical formulas (or functions), all of which are based on extremely complex cryptography. A hash is a certain piece of information, ranging from a letter or number to even an entire word or text file. A hash function is a cryptography-based math equation where you input a hash value into the equation then get an encrypted string of numbers & letters as a result (the hash). Let me help you visualize it to make it easier. We’ll represent our hash function as h(x) = y, where h is the mathematical equation (aka the “hash function”), x is a dynamically-changing hash value, and y is the encrypted output (or hash). In the case of Bitcoin, the hash function that’s used is known as SHA-256 (which is an acronym for Secure Hash Algorithm, which uses a 256-bit hash). The hash value that you input can be as many different numbers & letters as you’d like, but the output will always be a string of 64 letters or numbers. The reason why this is so secure is because SHA-256 is a one-way formula, meaning it’s impossible to reverse engineer your output to find out what the original hash value was. So proof-of-work is essentially just that: you have a given hash function you’re required to use along with a 64-digit answer; and as a miner, you set your computer to “work” by plugging in a bunch of different hash values in an attempt to guess the right answer. Once you do so, you’re able to validate a transaction, add it to a block, and get rewarded for your efforts in the form of Bitcoin, which are released as block rewards. Think of mining as simply a race to guess the right answer. The miner who gets the right answer first gets the reward. 2. Proof-of-Stake The proof-of-stake protocol differs from proof-of-work in the sense that mining power is determined by the number of coins you hold of that particular cryptocurrency; the more coins you hold, the more mining power you have. Mining power with proof-of-work, on the other hand, is determined by how powerful your computer is & how much available electricity you have at your disposal that you can direct towards mining. In proof-of stake, holding ownership of the coins demonstrates your “stake” in the network. Methods have been implemented to grant smaller miners a chance to mint the next block, such as randomized block selection & coin age based selection. There’s also the option of running a masternode, which I discussed in my previous video on hard forks. One of the advantages of the proof-of-stake protocol is that it solves the Tragedy of Commons issue, which states that eventually, at some point in time, once all 21,000,000 Bitcoin have been rewarded & are in circulation, Bitcoin miners will be less motivated to mine in the Bitcoin network since there will no longer be any block rewards at that point, and the only way they’ll only be able to earn Bitcoin is from transaction fees. Less miners means more opportunity for an attack on the network, since it’ll be easier to control 51% of the network’s computational power. Proof-of-stake solves that by putting your own coins & investment at stake. 1. Which is better? Both protocols have their own advantages & disadvantages. Proof-of-work allows for not just miners, but also developers & the coin’s community members to vote on potential changes to be implemented into the network. But on the flipside, proof-of-work requires exorbitant amounts of electricity to run mining rigs. As of 2017, the Bitcoin mining network used more electricity in a year than all of Ireland as a whole. Each Bitcoin transaction uses an average of 300 kilowatt hours of electricity, which is enough to bring 36,000 kettles full of water to a boil. Proof-of-stake, on the other hand, is said to be more energy-efficient than proof-of-work, while at the same time more secure. But its biggest disadvantage is that the miners (or stakeholders) are the ones who hold all the power. Unlike in proof-of-work, miners able to theoretically implement whatever changes they so choose without having to get approval from developers or community members. This contradicts the coin’s supposed “decentralized nature” by potentially putting all the voting power & control in the hands of a centralized few.
