Quantum cryptography and Post-Quantum cryptographyHello guys today i want to explain Quantum cryptography and Post-quantum cryptography and how they can affect blockchain security and whats the solution. lets start with a brief explanation of cryptography: Cryptography is the process of encrypting data, or converting plain text into scrambled text so that only someone who has the right “key” can read it. NOW what is quantum cryptography? Quantum cryptography simply uses the principles of quantum mechanics to encrypt data and transmit it in a way that cannot be hacked. and what is Post-Quantum cryptography? Post-quantum cryptography refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against an attack by a quantum computer. These complex mathematical equations take traditional computers months or even years to break. However, quantum computers running Shor’s algorithm will be able to break math-based systems in moments. How Quantum Cryptography Works? Quantum cryptography, or quantum key distribution (QKD), uses a series of photons (light particles) to transmit data from one location to another over a fiber optic cable. By comparing measurements of the properties of a fraction of these photons, the two endpoints can determine what the key is and if it is safe to use. The sender transmits photons through a filter (or polarizer) which randomly gives them one of four possible polarizations and bit designations: Vertical (One bit), Horizontal (Zero bit), 45 degree right (One bit), or 45 degree left (Zero bit). The photons travel to a receiver, which uses two beam splitters (horizontal/vertical and diagonal) to “read” the polarization of each photon. The receiver does not know which beam splitter to use for each photon and has to guess which one to use. Once the stream of photons has been sent, the receiver tells the sender which beam splitter was used for each of the photons in the sequence they were sent, and the sender compares that information with the sequence of polarizers used to send the key. The photons that were read using the wrong beam splitter are discarded, and the resulting sequence of bits becomes the key. If the photon is read or copied in any way by an eavesdropper, the photon’s state will change. The change will be detected by the endpoints. In other words, this means you cannot read the photon and forward it on or make a copy of it without being detected. The Solution We Need Now for Tomorrow! The need for unbreakable encryption is staring us in the face. With the development of quantum computers looming on the horizon, the integrity of encrypted data is at risk now. Fortunately, quantum cryptography, through QKD, offers the solution we need to safeguard our information well into the future – all based on the complex principles of quantum mechanics. In January 2022 a team at Sussex University spin-out company Universal Quantum published research on transit attacks which calculated that it would require a quantum computer with a 1.9 billion qubit-capacity to break Bitcoin’s encryption in the required ten-minute window (this is the time taken for a Bitcoin to be mined). Even at 317 million qubits it would take an hour and 13 million qubits for a day. For context, IBM’s superconducting quantum computer currently has a 127-qubit processor.

Bank Nifty AlgoHere I developed after many years how typically Banknifty indices operate sudden huge move, its completely controlled by Big players after trapping retailers SL. There are few methods identified and back tested after several months. Basically its perfectly works with Banknifty future & Option buyers. Can easily capture 200 to 300 points from sudden level in intraday. The purpose of this indicator mainly to eliminate Fear, greedy, emotions., its basically "KONW YOUR RISK & REWARD" & Kindly note this for only intraday players how to use it. Its updated version of Millreeh This indicator facility to plot following for some reason, 1. SMA 20 & 200 2. Swing forming in MTF (current chart TF, 15, 1 Hr ) The basic setup categories two way 1. Setup2 - Just taking out retailer SL zone and trade against Retailers & RR 1:5 2. Algorithm Setup - Join hand with big players. (When S2 Fails) & RR 1:10 How to use for Setup2: 1. Keep your Chart 3 mins 2. Identify Reaction zone/area ( Where to take trade) 3. Action center (When to enter & Know the SL level) 4. Exit Trade ( Know the Target level) For Algo setup its need lot experience to spot and its move like free fall most of time.

Position Sizing (Course #0)My very first course was going to be the winning rate. As I wrote down the other ones, I realized that position sizing, understanding what it is and how it works, was actually the most important part of it all. Therefore, I have decided to create this course #0 as the one you MUST take first to understand the other stuff. Understanding position sizing is very tricky actually. The very first time I learned about it was with Crypto Cred. He’s got a lot of great courses on trading and Technical Analysis, I also recommend you checking him out. So here is what most people think about doing: I will buy 100% of my account balance into bitcoin ($1,000 account), my account size will then be $1,000. Or, I will buy with 15% of my account, so my position will be $150. Even better, I will go 10x and my position size will be $10,000. This is great and all, but this is NOT how you should look at it. Whenever you trade, you MUST – SHALL – HAVE TO HAVE – an plan on where and why do you enter, where you need to exit at profit AND where you need to exit at loss. If you don’t want to accept that, no good. If you want to invest into something, you MUST – SHALL – HAVE TO HAVE – an plan on where and why do you enter, where you need to exit at profit AND where you need to exit at loss. If you don’t want to accept that, no good. It’s like driving, you must know when to turn, accelerate and break. So, because you will have a plan, you will know OR you will decide where to put your Stop Loss. For example, you want to put your stop loss the 20 EMA. Or, you want to put your stop loss at the low of the previous candle. Or, you want to put your stop loss 0.5% below your entry. Or, you want to put your stop loss at the previous support level. Once you have decided where to put your Stop Loss, based on your strategy and on the structure of the market/chart, you will need to decide how much you will risk on that trade. Basically, trading is like betting. You will bet/risk an amount of money, hoping to make a profit. To give you an idea, 1% risk is cool, if you want fast results you can go to 2-3% (of your account balance). Some great traders like to do 5-20%, but this is super high risk. 5-20% on an intraday trading strategy (in and out during the same day), then this is degen to me. On an intraday 1-2% risk per trade is good. So now, you are starting to be good at position sizing: you know where your stop loss will be and you know how much you will risk. Let’s go back to our examples of stop losses. Example 1: you want to put your stop loss the 20 EMA Example 2: you want to put your stop loss at the low of the previous candle Example 3: you want to put your stop loss 0.5% below your entry Example 4: you want to put your stop loss at the previous support level On the above chart, here are the distance between your entry and the stop losses: Example 1, the 20 EMA is 0.28% below your entry. Example 2, the low of the previous candle is 2.30% below your entry. Example 3, the stop loss is exactly 0.50% below the entry, like you decided. Example 4, the previous support level is 4.60% below your entry. Now let’s calculate your position size: Magic Formula: Position size = Risk % / Distance to SL % Example 1: 1% / 0.28% = 3.57 This means your position size will be 3.57 times your account balance. Example 2: 1% / 2.30% = 0.437 This means your position size will be 0.437 times your account balance, so a little bit less than half of it. Example 3: 1%/0.5% = 0.50 Your position size is equal to half your account. Example 4: 1%/4.60% = 0.22 Your position size will be 0.22 times your account. So now, do you understand that leverage should only be necessary when your strategy calls for a Stop Loss that is positioned at a distance that is less than your risk %? This is example 1. You should NEVER think “I want to use 10x” just for fun. You should only apply leverage because your position size calculation told you so. Conclusion: Position Sizing is the calculation of how much should your position be, so that when you hit your SL, you only lose what you planned losing. Position size = RISK % / DISTANCE TO SL %

What is the Algorand blockchain.Algorand's PPoS consensus algorithm distinguishes it from other blockchain networks that help solve blockchain trilemma. What is Algorand? Algorand is a blockchain network created in 2017 by Silvio Micali, an MIT professor who won the Turing Award for his work in cryptography. Algorand is a decentralized permissionless blockchain protocol that anyone can use to develop applications and transfer value. The Algorand protocol is powered by a novel consensus algorithm that enables fast, secure and scalable transactions. Algorand addresses the common issues that most older blockchains have, specifically concerning scalability and consensus. The blockchain uses Pure proof-of-stake (PPoS), a consensus protocol that selects validators at random according to the weight of their stake in ALGO coins. What is Algorand trying to solve? The Algorand protocol is designed to solve three of the biggest problems most blockchains face: security, scalability and decentralization. Dubbed as the “blockchain trilemma,” the Algorand network claims to address the following three major issues. Security The Algorand protocol is secure against malicious attacks, making it ideal for transacting, holding high-value assets and building secure enterprise applications. It maintains security on both network and consensus protocol levels and protects individual users’ accounts. Scalability The Algorand protocol can handle a large number of transactions per second, making it a more scalable solution than Bitcoin or Ethereum. Algorand’s consensus protocol does away with the need for computational power used in Bitcoin to solve cryptographic problems. Instead, the protocol’s computation cost per user is only used to generate and verify signatures, as well as operations requiring simple counting. According to Algorand, it can “scale to millions of users and sustain a high transaction rate without incurring significant cost to participating users.” Decentralization Algorand is entirely decentralized with no central authority or singular locus of control. Transactions are verified by participating nodes in the network and each node has an equal say in decision-making. This makes Algorand a very decentralized system. Everyone on the network also has a chance of being part of the committee of users that approve each block because the selection is both random and confidential. There is no fixed committee and its nodes are run by people from all over the world. How does Algorand work? What sets Algorand apart from other blockchains is its use of PPoS, a consensus algorithm that employs a Byzantine agreement protocol. Should a node be compromised, staked the native token ALGO owned by participants in the network would automatically be protected with unique keys. Bitcoin’s consensus mechanism, proof-of-work (PoW), requires large amounts of energy and computing power to create and validate new blocks. PPoS, on the other hand, allows the creation and validation of new blocks in a faster and more efficient manner. This is done by randomly selecting ALGO holders to validate and approve each block in the chain. A new group, or committee, is selected for each new block. Through the PPoS protocol, only users with large holdings of ALGO can theoretically engage in malicious activities that could potentially compromise other users’ security. However, since the system is based on codependency among participants, malicious activities would also result in a deterioration of their ALGO. Hence, such malicious activity would not be rewarding for any majority holder. Algorand can process 1,000 transactions per second and all transactions will be final and instantaneous. Algorand also has a fixed supply of 10 billion tokens to add an inflation-resistant mechanism to the network. The majority of these tokens are currently locked up and have yet to be distributed. Algorand protocol structure The Algorand protocol is built on three fundamental concepts: Transactions: Transactions are the basic unit of account in the Algorand network. They are used to transfer value and are verified by all participating nodes in the network. Blocks: Blocks are groups of transactions collected into a single unit and verified by the consensus algorithm. Consensus: The consensus algorithm is responsible for verifying blocks and ensuring that they meet the requirements of the Algorand protocol. It also rewards users who participate in its operation. Algorand staking mechanism: Pure proof-of-stake Under Algorand’s PPoS approach, the influence held by a user on the choice of a new block is proportional to the number of tokens they have in the system, also called their stake. Each user has a chance to be chosen with the weight of their proposals and votes being directly related to their stake. Users are selected randomly and secretly for the purpose of proposing blocks and voting on such block proposals. Through this approach, the network’s security is tied to the honesty of the majority of the users in its economy. As long as most of the money is in honest hands, the system will remain secure. This approach is in opposition to other consensus mechanisms like PoW, DPoS or BPoS wherein small groups within the economy are responsible for the whole system’s security. By principle, a small fraction of users can prevent other users from transacting with these approaches. Algorand’s approach makes it virtually impossible for holders with smaller stakes in the system to harm the whole network. Meanwhile, majority holders would also not dare to act maliciously, as such actions will result in the devaluation of their own assets and a reduction in the currency’s purchasing power. Algorand block production under PPoS New blocks are constructed in two phases under Algorand’s PPoS mechanism. During the first phase, a single token is selected at random. The owner of this token is the user in charge of proposing the next block. During the second phase, 1000 tokens are selected randomly out of all the tokens in the system. The owners of these tokens make up the phase-2 committee, and they are in charge of approving the block proposed by the user in phase 1. Related: What is cryptocurrency? A beginner’s guide to digital currency It is possible for a committee member to be chosen more than once. This also means that a member will have more than one vote in the committee when approving the next block. The second phase in Algorand’s block production process was put in place to combat any percentage of bad actors. By choosing 1000 tokens at random, the malicious intentions of these bad actors will be trumped by the majority and act in accordance with the rules for the welfare of the network. Algorand’s native cryptocurrency: ALGO The native currency of the Algorand network is called ALGO. ALGO tokens are used to pay for transaction fees and reward users who participate in the network's consensus process. Transactions with ALGO happen in less than four seconds, regardless of how many transactions you do in a day. Transaction fees are also minimal. Unlike Ethereum, which is notorious for high gas fees, Algo transactions cost very little. How can I buy ALGO cryptocurrency? There are several methods for purchasing ALGO. You may buy it directly from another individual in person or over the internet, as you would with any other cryptocurrency. Alternatively, you may look for a crypto ATM near you that offers ALGO. However, crypto ATM rates can be prohibitive, and there’s no assurance that you’ll be able to locate a counterpart willing to make the trade. The easiest way to buy ALGO is on a cryptocurrency exchange. Some popular exchanges that offer ALGO include Binance, Kraken and Coinbase. You can buy ALGO with a credit or debit card on these exchanges. To do so, you first need to get a crypto wallet to hold the ALGO. Some wallets that support ALGO are Pera Wallet, My Algo, Coinbase and Ledger. Once you’ve set up your wallet, you can now fill your wallet by finding an exchange that supports ALGO. Set up an account on the exchange if you already do not own one and get it verified. Select "Algorand" from the list of assets to begin your trade. Input the fiat amount to buy ALGO coins and preview your purchase before you finally submit.

IPDA on CryptoFirst off I want to state that I'm an ICT YouTube Student and have studied at least a quarter of his videos and am now keeping up and studying his new 2022 Mentorship as well. I'm not going to sit here and pretend to be some know it all professional because I'm not. But I do have a clearer understanding to the market now than I ever have before and can not trade anything with a retail mindset anymore. With that said if you don"t agree with Smart Money Concepts or the Interbank Price Delivery Algorithm please keep your comments to yourself. Now this is my Analysis thus far using the knowledge I have shuffled through over and over till I finally found stability in Cryptocurrency. Enjoy!
