Mining Bitcoin with pencil and paper
Bitcoins are mined using a cryptographic algorithm called SHA-256. This algorithm is simple enough to be done with pencil and paper, as I show in this video. Not surprisingly, this is a thoroughly impractical way to mine. One round of the algorithm takes 16 minutes, 45 seconds which works out to a hash rate of 0.67 hashes per day.

How secure is 256 bit security?
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 Home page: https://www.3blue1brown.com/ 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 the 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 and cryptocurrency mining explained
https://www.udemy.com/blockchain-for-business-the-new-industrial-revolution/?couponCode=YOUTUBE Bitcoin and cryptocurrency mining explained with the the Byzantine Generals Problem. The Byzantine Generals problem was first introduced in a computer science paper published in 1982. The problem discussed in the paper is that reliable computer systems must be able to function effectively in the presence of faulty components that may send conflicting information to different parts of the system. This issue is even more acute when we talk about decentralized computer networks. Imagine the following thought experiment: The Byzantine army has surrounded an enemy city. The army is organized into several units. Each unit is commanded by a general and they all need to come up with a coordinated plan of action. However, they are located away from each other and the only means to communicate among themselves is via messages. To make things more complicated, one or more of the generals are possibly traitors. The presence of disloyal generals means that misleading messages could be sent aiming to disrupt any coordinated plan of action, be it attack or retreat. To find a successful solution to this conundrum, the Byzantine army needs to find its path to coordinated action, one way or another. To achieve this, the Byzantine army needs an algorithm that works effectively towards a coordinated outcome where the loyal generals follow it and the traitors don’t. Now that you are familiar with the problem, let’s see its solution. It is called the Byzantine Fault Tolerance algorithm. Over the years, there have been several proposed theoretical solutions involving game theory and math. The first practical implementation of Byzantine Fault Tolerance algorithm came with the Bitcoin’s Proof-of-Work. In this case the “generals” are nodes on the Bitcoin network, also known as “miners”. A network node is a connection point that can receive, create, store and send data across a network. In other words, nodes are the connected dots that make up a network. To simplify, think of it in the following way. In the image we traditionally use to depict a blockchain, every single computer is a separate node. They are all connected and can receive, create, store, and send data to each other. In the context of the Byzantine Fault Tolerance algorithm, the important concept to grasp is that these mining nodes start from the assumption that nobody else on the network can be trusted. Proof-of-Work secures network consensus even in the presence of non-compliant nodes. That is, even if there are some Byzantine generals who are not acting in the army’s best interest, coordinated action can still be achieved. Let’s see how this mechanism works in Bitcoin. As we all know by now, Bitcoin is a peer-to-peer network where all activities are done by its users through appropriate software and hardware. These activities include making transactions, receiving transactions, and verifying and transmitting transactions. Now, this is where we need to introduce the concept of “mining”, which many of you have probably heard. Mining is an activity, carried out by network participants, which involves Proof-of-Work and results in generating new coins as a reward for the miner who successfully did this Proof-of-Work first for each new block.

What is Hashing & Digital Signature in The Blockchain?
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.

Blockchain tutorial 3: Hash
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.

How Does Monero Work?
Monero is a cryptocurrency that enables private transactions. That means the sender, receiver, and transaction amount are not publicly viewable, unlike Bitcoin's blockchain. Monero's transactions stay private using the technology of ring signatures, ringCT, stealth addresses, and I2P routing. I'll explain how all of this works in this video. I do not condone the use of this technology for illegal transactions. This is powerful stuff, ideally, we start using this as a stepping stone towards a world where we get paid for our transactional data (and all the rest of our data).

Consensus and Mining on the Blockchain
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.

What is Bitcoin? How to Mine Bitcoin? [ Bangla Video]
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 …..

Blockchain/Bitcoin for beginners 9: Bitcoin difficulty, target, BITS  - all you need to know
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.

IOTA tutorial 18: Merkle Tree
If you like this video and want to support me, go this page for my donation crypto addresses: https://www.youtube.com/c/mobilefish/about This is part 18 of the IOTA tutorial. In this video series different topics will be explained which will help you to understand IOTA. It is recommended to watch each video sequentially as I may refer to certain IOTA topics explained earlier. The main objective of this video is to provide you with some basic knowledge about the Merkle tree. The Merkle tree is used in IOTA's Masked Authenticated Messaging. IOTA's Masked Authenticated Messaging will be explained in IOTA tutorial 19. A hash tree or Merkle tree is a tree structure in which each leaf node is a hash of a block of data and each non-leaf node is a hash of its children. This results in a single hash called the Merkle root. If every node has two children, the tree is called a binary hash tree. Why use a Merkle tree? Why not hash all messages (m0-m15), append the hashed messages and then hash it all to get one root hash value. Bob get the root hash from a trusted source. If Alice wants to proof to Bob that m6 is not tampered with, she needs to send message m6 and all other hashed values: H(m0), H(m1), H(m2), H(m3), H(m4), H(m5), H(m7), H(m8), H(m9), H(m10), H(m11), H(m12), H(m13), H(m14) and H(m15) to Bob. Bob hashes message m6, append all hashes to a single string and hash this string to get one root hash. Bob compares this new root hash with the trusted source root hash to check if message m6 is not tampered with. In this example Alice has to provide 15 hashed values and the message m6 to Bob to prove that message m6 is not tampered with. A much better solution is using a Merkle tree (16 leaves) Again as before Bob gets the root hash from a trusted source. If Alice wants to proof that m6 is not tampered with, she needs to send m6 and 4 hashed values to Bob. With the received information Bob calculates the root hash value. Bob compares this root hash with the trusted source root hash to check if message m6 is not tampered with. In this example Alice only needs to provide 4 hashed values and the message m6 to Bob to prove that message m6 is not tampered with. Using a Merkle tree provides integrity and validity of your data using a small amount of data that a trusted authority has to maintain. This also means little memory / disk space is needed. If a Merkle tree has more leaves less hashed values are needed, in comparison to the number of leaves, to validate if a message is not tampered with. A perfect Merkle binary tree has the following properties: - The number of leaves is always 2n (n=0, 1, 2, 3,..). - Each node has 0 or 2 children. - All leaves are on the same level. In a perfect binary tree the following formulas can be applied: Total number of leaves = L = (N + 1) / 2 Total number of nodes = N = 2L - 1 Total number of levels = LV = log2(L) + 1 = (ln(L) / ln(2)) + 1 Number of leaves = L = 1 Number of nodes = N = 1 Number of levels = LV = 1 Number of leaves = L = 2 Number of nodes = N = 3 Number of levels = LV = 2 Number of leaves = L = 4 Number of nodes = N = 7 Number of levels = LV = 3 Number of leaves = L = 8 Number of nodes = N = 15 Number of levels = LV = 4 Number of leaves = L = 16 Number of nodes = N = 31 Number of levels = LV = 5 Check out all my other IOTA tutorial videos: https://goo.gl/aNHf1y Subscribe to my YouTube channel: https://goo.gl/61NFzK The presentation used in this video tutorial can be found at: https://www.mobilefish.com/developer/iota/iota_quickguide_tutorial.html #mobilefish #howto #iota

Altcoins Explained. ETH BCH NMC DASH ETC LTC XMR ZEC XZC Altcoins are cryptocurrencies other than Bitcoin. The majority of altcoins are forks of Bitcoin with small uninteresting changes. This page categorises different ways altcoins have modified Bitcoin. Different proof-of-work algorithm The PoW algorithm used for mining Bitcoin is SHA2. It was chosen because it is fast to verify and has been critically analyzed. SHA2 has had ASICs developed for it meaning there is a much smaller risk of centralization. The following mining algorithms are being used in different altcoins: Scrypt proof of work Combination of hashing algorithms in series (e.g. X11) Combination of hashing algorithms in parallel (e.g. Myriad algorithm) The problem with having an algorithm that is "easy to mine with" (referring to the ability to CPU or GPU mine profitably) is that mining should be hard in order to secure the network. When a mining algorithm is difficult to make ASICs for, there is a higher barrier to entry. A high barrier to entry increases the time that the first group to create ASICs will monopolize the market (and the time the network is vulnerable to a 51% attack from a single source). Many argue that the creators or the developers could simply change the mining algorithm when an ASIC is developed, but this defeats the purpose of decentralized consensus by causing centralization.[1] If these cryptocurrencies do have a healthy number of companies producing ASICs and have avoided centralization, they still are using algorithms that take longer to verify than SHA2. Therefore, at best a cryptocurrencies with merely a hashing algorithm change are as good as an exact clone of Bitcoin and not better (however since Bitcoin already exists, an exact clone of Bitcoin has no innovation or value). If the hashing algorithm is slower, as most altcoin algorithms are, it is a disadvantage because it takes more processing time to validate a block and increases the number of organic re-orgs (makes it easier to double spend). Proof Of Stake In Proof of Stake, instead of sacrificing energy to mine a block, a user must prove they own a certain amount of the cryptocurrency to generate a block. The more stake you own, the more likely you are to generate a block. In theory, this should prevent users from creating forks because it will devalue their stake and it should save a lot of energy. Proof of Stake sounds like a good idea, but ironically, there is the "Nothing at Stake" problem. Because mining Bitcoin is costly, it is not smart to waste your energy on a fork that won't earn you any money, however with Proof of Stake, it is free to mine a fork. An example of a nothing at stake attack is an attacker buying lots of "old stake" from users inexpensively (inexpensive to users who no longer have stake in the currency). This can be made convenient by offering small payments to users for uploading their wallet.dat. Eventually after accumulating enough "old stake", the user can begin creating blocks and destroying as many or more coin days than the network was at that time. This block generation can be repeated until it catches up to and beats the current main-chain very cheaply. There are also "stake grinding" attacks which require a trivial amount of currency. In a stake[2] grinding attack, the attacker has a small amount of stake and goes through the history of the blockchain and finds places where their stake wins a block. In order to consecutively win, they modify the next block header until some stake they own wins once again. This attack requires a bit of computation, but definately isn't impractical. Because these attacks exists, including Peercoin[3] and Blackcoin[4] proof of stake cryptocurrencies have "master" public keys that control the blockchain. This class of cryptocurrency is either insecure or centralized, however proof of stake (based on a PoW currency) is useful in some systems because gaining stake is costly, but it isn't workable for bootstrapping distributed consensus. Application Built on Top of a Cryptocurrency Bitcoin is a lot like HTTP. It is an application layer protocol and tools can be built on it (like websites can be built on HTTP). There is a class of cryptocurrencies that promise features like casino websites and exchanges and anonymity protocols to be built on top of them.

Linear Regression - Machine Learning Fun and Easy

Today I’ll be talking about Linear Regression. We show you also how implement a linear regression in excel Linear regression attempts to model the relationship between two variables by fitting a linear equation to observed data. One variable is considered to be an explanatory variable, and the other is considered to be a dependent variable. Dependent Variable – Variable who’s values we want to explain or forecast Independent or explanatory Variable that Explains the other variable. Values are independent. Dependent variable can be denoted as y, so imagine a child always asking y is he dependent on his parents. And then you can imagine the X as your ex boyfriend/girlfriend who is independent because they don’t need or depend on you. A good way to remember it. Anyways Used for 2 Applications To Establish if there is a relation between 2 variables or see if there is statistically signification relationship between the two variables- • To see how increase in sin tax has an effect on how many cigarettes packs are consumed • Sleep hours vs test scores • Experience vs Salary • Pokemon vs Urban Density • House floor area vs House price Forecast new observations – Can use what we know to forecast unobserved values Here are some other examples of ways that linear regression can be applied. • So say the sales of ROI of Fidget spinners over time. • Stock price over time • Predict price of Bitcoin over time. Linear Regression is also known as the line of best fit The line of best fit can be represented by the linear equation y = a + bx or y = mx + b or y = b0+b1x You most likely learnt this in school. So b is is the intercept, if you increase this variable, your intercept moves up or down along the y axis. M is your slope or gradient, if you change this, then your line rotates along the intercept. Data is actually a series of x and y observations as shown on this scatter plot. They do not follow a straight line however they do follow a linear pattern hence the term linear regression Assuming we already have the best fit line, We can calculate the error term Epsilon. Also known as the Residual. And this is the term that we would like to minimize along all the points in the data series. So say if we have our linear equation but also represented in statisitical notation. The residual fit in to our equation as shown y = b0+b1x + e ------------------------------------------------------------ Support us on Patreon ►AugmentedStartups.info/Patreon Chat to us on Discord ►AugmentedStartups.info/discord Interact with us on Facebook ►AugmentedStartups.info/Facebook Check my latest work on Instagram ►AugmentedStartups.info/instagram Learn Advanced Tutorials on Udemy ►AugmentedStartups.info/udemy ------------------------------------------------------------ To learn more on Artificial Intelligence, Augmented Reality IoT, Deep Learning FPGAs, Arduinos, PCB Design and Image Processing then check out http://augmentedstartups.info/home Please Like and Subscribe for more videos :)

Bitcoin Q&A: Energy consumption
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.

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.

M17: Algorithm-driven mining doesn't make a cryptocurrency more democratic, but less transparent
There are minable cryptocurrencies like Bitcoin and Ethereum and there are pre-mined ones, like Ripple and Zold (our own non-Blockchain crypto). We've had a discussion about which one is better for the economy and for the users. Long story short, I believe that pre-mined currencies make more sense, business wise This is the website of Zold cryptocurrency: https://www.zold.io My Telegram channel is here: https://t.me/yegor256news #programming #cryptocurrency #bitcoin #zold #ethereum

Blockchain technology explained – simple explanation of Blockchain technology
A blockchain is a distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. A blockchain is normally managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once validated and recorded, the data in any given block cannot be altered without the alteration of all subsequent blocks, which requires collusion of the network majority. Blockchain is going to be a disruptive technology in the coming years. To know the concept of Blockchain , we need to get some understanding and basic concepts about, SHA2 , hash, distributed network etc. Hash. Hash is nothing but a digital fingerprint of information created with SHA2 algorithm. As name mention, each and every character, word or sentence will have a unique hash code. So if I put “My name is Girish”, it spit out a unique hash code and it will be always unique. Now forget about the above sentence and if you have a huge article written, again there will be unique hash for it. It is very interesting that even if it is a single character or a huge library of information, hash code will be of same length. Hash is a digital fingerprint, it is unique for every combination of characters. Block. Block is collection of data, “My name is Girish” is the data in our earlier example. In BLOCK, data along with a unique signing key together will generate a hash which will be unique for this combination. It essentially means if any one changes data then hash will change. As mentioned above , here I added an additional G in the end, now hash also get changed and mark it as unsigned or un-certified or invalid. Now to get the certified or signed hash, the option is to remove that additional “G” from the box or replace “114290” which is the earlier signing key and guess a new signing key which will certify this data with a new hash. Mining. Now I programmatically tried from 1 till I get a signed hash, and the magic number was 31615 in this case. In a simple term, this is known as mining. We will get into this in detail soon. Block is collection of data along with a signing key, combination of data and signing key creates a unique hash. Blockchain. Blockchain is a continuous chain of blocks and, interestingly it points to a block previous to it. Consider this as an array of data & sign key combination. Ideally it is a chain of blocks which are certified or valid. Assume any one of the block in this chain got altered, the chain after it also get invalidated. This is how the integrity of a Blockchain is maintained without a third party or a trustee. Let us see the complications involved if someone try to validate any single block in this entire chain. To achieve this one has to go and fix entire chain by guessing the right signing key, which is such a big resource intense activity which is practically impossible. That is why we say data written to a Blockchain is immutable. Distributed Blockchain. In the above example , the entire Blockchain from the node where it got a fraud entry become invalid, but as we discussed these nodes can be signed with a new key and make it valid again. Even though it is resource intense, it can be done on a relatively smaller chain. Distributed Blockchain is as good as having the entire chain of blocks distributed to everyone in the network. This help to make things a bit for difficult to corrupt the system. Now we have copies of certified blocks with thousands or millions of people in the network. Blockchain system can now easily validate and identify which of the chains are faked or corrupted and so ignore it. Rule of majority works here. Now we know the basic concept of Blockchain, we will see the practical implementation of Blockchain which is bitcoin. Many people confuse bitcoin with Blockchain and vise versa. Blockchain is a concept and Bitcoin is a practical application build on top of Blockchain concept. There are many other applications which are being build which may revolutionize banking & financial industry. There are more to be discussed about bitcoin implementation on how is the opening balance and closing balance maintained etc. We will discuss those in another tutorial. Hope this helps you to understand the Blockchain technology better. To read more visit http://girishg.net/blockchain/

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.

Zerocoin: Anonymous Distributed E-Cash from Bitcoin
Bitcoin is the first e-cash system to see widespread adoption. While Bitcoin offers the potential for new types of financial interaction, it has significant limitations regarding privacy. Specifically, because the Bitcoin transaction log is completely public, users� privacy is protected only through the use of pseudonyms. In this talk we discuss Zerocoin, a cryptographic extension to Bitcoin that augments the protocol to allow for fully anonymous currency transactions. Our system uses standard cryptographic assumptions and does not introduce new trusted parties or otherwise change the security model of Bitcoin. We detail Zerocoin�s cryptographic construction, its integration into Bitcoin, and examine its performance both in terms of computation and impact on the Bitcoin protocol.
