The system is peer-to-peer, and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain. Since the system works without a central repository or single administrator, bitcoin is called the first decentralized digital currency. Besides being created as a reward for mining, bitcoin can be exchanged for other currencies, products, and services in legal or black markets. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment. According to research produced by Cambridge University in 2017, there are 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.

ETH works as a platform for numerous other cryptocurrencies, as well as for the execution of decentralized smart contracts.Ethereum was first described in a 2013 whitepaper by Vitalik Buterin. Buterin, along with other co-founders, secured funding for the project in an online public crowd sale in the summer of 2014. The project team managed to raise $18.3 million in Bitcoin, and Ethereum’s price in the Initial Coin Offering (ICO) was $0.311, with over 60 million Ether sold. Taking Ethereum’s price now, puts the return on investment (ROI) at an annualized rate of over 270%, essentially almost quadrupling your investment every year since the summer of 2014.The Ethereum Foundation officially launched the blockchain on July 30, 2015, under the prototype codenamed “Frontier.” Since then, there have been several network updates — “Constantinople” on Feb. 28, 2019, “Istanbul” on Dec. 8, 2019, “Muir Glacier” on Jan. 2, 2020, “Berlin” on April 14, 2021, and most recently on Aug. 5, 2021, the “London” hard fork.Ethereum’s own purported goal is to become a global platform for decentralized applications, allowing users from all over the world to write and run software that is resistant to censorship, downtime, and fraud.

A hard fork is, in fact, a blockchain divided into two parts, each of which becomes its own cryptocurrency with its own unique blockchain.Unlike a soft fork, which is an update of the blockchain, where only one of the separable parts of the blockchain remains valid. Thus, when the fork happens, anyone who holds BTC will receive the same amount of BCH.The formation of BCH occurred as a result of disagreements within the BTC community. Groups of BTC miners and developers were concerned about its scalability, and they were not sure about the blockchain's plans to adopt segregated witness (SegWit) technology.These groups believed that although it was necessary (with the increasing size of the BTC network, the blockchain could barely cope with the increased transaction volumes), this proposed update did not correspond to the decentralized philosophy of Satoshi Nakamoto. As a result, they agreed that the only way to overcome the scalability problem is to increase the maximum block size.Therefore, a hard fork was proposed in which the BTC blockchain will be divided into two parts. One of them will process more transactions at a faster rate than BTC. That's how BCH appeared.

When it was released in July 2014, one of its goals was boosting financial inclusion by reaching the world’s unbanked — but soon afterward, its priorities shifted to helping financial firms connect with one another through blockchain technology.The network’s native token, lumens, serves as a bridge that makes it less expensive to trade assets across borders. All of this aims to challenge existing payment providers, who often charge high fees for a similar service.Stellar is unique because every transaction costs just 0.00001 XLM. Given how one unit of this cryptocurrency only costs a few cents at the time of writing, this helps ensure that users keep more of their money.Few blockchain projects have managed to secure partnerships with big-brand technology companies and fintech firms. A few years ago, Stellar and IBM teamed up to launch World Wire, a project that allowed large financial institutions to submit transactions to the Stellar network and transact using bridge assets such as stable coins.Although other blockchains have community funds, meaning that grants can be given to projects that help further the ecosystem, Stellar allows its users to vote on which ventures should be given this support.

Litecoin has a block time of just 2.5 minutes and extremely low transaction fees, making it suitable for micro-transactions and point-of-sale payments.Litecoin was released via an open-source client on GitHub on Oct. 7, 2011, and the Litecoin Network went live five days later on Oct. 13, 2011. Since then, it has exploded in both usage and acceptance among merchants and has counted among the top ten cryptocurrencies by market capitalization for most of its existence.The cryptocurrency was created by Charlie Lee, a former Google employee, who intended Litecoin to be a "lite version of Bitcoin," in that it features many of the same properties as Bitcoin—albeit lighter in weight.

Parts from each type class come in four different rarity scales: common, rare, ultra-rare, and legendary — and Axies can have any combination of body parts, making them highly variable and often rare and unique.Each Axie is a non-fungible token (NFT) with different attributes and strengths and can be entered into 3v3 battles, with the winning team earning more experience (exp) points that are used to level up an Axie's stats or evolve their body parts. These Axies can be bred together to produce new and unique offspring, which can be used or sold on the Axie marketplace.The Axie Infinity ecosystem also has its own unique governance token, known as Axie Infinity Shards (AXS). These are used to participate in key governance votes and will give holders a say in how funds in the Axie Community Treasury are spent.

It shares many similarities, such as a fixed total supply of 21 million units.Transactions can be "transparent" and similar to bitcoin transactions in which case they are controlled by a t-addr, or they can be "shielded" and are controlled by a z-addr. A shielded transaction uses a type of zero-knowledge proof called zk-SNARKs, which provides anonymity to the coin holders in the transaction. Zcash coins are either in a transparent pool or a shielded pool. As of December 2017 only around 4% of Zcash coins were in the shielded pool and at that time most cryptocurrency wallet programs did not support z-addrs and no web-based wallets supported them. The shielded pool of Zcash coins was further analyzed for security and it was found that the anonymity setcan be shrunk considerably by heuristics-based identifiable patterns of usage.Zcash affords private transactors the option of "selective disclosure", allowing a user to prove payment for auditing purposes. One such reason is to allow private transactors the choice to comply with anti-money laundering or tax regulations. "Transactions are auditable but disclosure is under the participant's control. The company has hosted virtual meetings with law enforcement agencies around the U.S. to explain these fundamentals and has gone on the record of saying that "they did not develop the currency to facilitate illegal activity".While miners receive 80% of a block reward, 20% is given to the "Zcash development fund": 8% to Zcash Open Major Grants, 7% to Electric Coin Co., and 5% to The Zcash Foundation.

On the other hand, advertisers have the opportunity to provide targeted advertising to increase engagement and reduce losses due to advertising fraud and advertising abuse.The Basic Attention Token itself is a unit of remuneration in this advertising ecosystem and serves for settlements between advertisers, publishers, and users. Advertisers pay for their advertising campaigns with BAT tokens. Of this budget, a small part is distributed to advertisers, and 70% is distributed among users — while intermediaries, who usually increase advertising costs, are excluded from the process, which increases profitability.Basic Attention Token was launched in 2017 after one of the fastest-selling initial coin offerings (ICO), during which the platform raised a total of $35 million in less than a minute.

Description of coins

 After the transaction has been broadcasted to the network, there’s usually no way of affecting it and you can just wait for the confirmation. To make this process faster for future transactions, you can choose to pay a higher fee when setting up your transaction so it can be included in the block earlier. 

If you do not want to spend time waiting for the transactions to be processed, you can pay a higher fee when setting up the next transaction. The process explained in detail

How to Speed up Unconfirmed Transactions on Crypto Trading Platform

How can I speed up unconfirmed transactions?

 Transactions within the blockchain network are validated only when a certain number of miners (minimum of 3) confirm their authenticity and include them in the blocks that become part of the blockchain. When your transaction is broadcasted to the network, you need to wait for it to be confirmed by a sufficient amount of miners in order to be validated. 

For a transaction to be validated it needs to be confirmed by a sufficient amount of miners. See a detailed explanation on this page. Cryptocurrency trading basics

What is Confirmation of Blockchain Transactions

What is a confirmation?

 Getting a wallet is fairly easy for most currencies. However, there are countless options out there depending on your needs and how safe you want to be. Any wallet you get will give you the possibility to generate addresses. If you don’t see a “Generate address” or “My addresses” button, you can normally generate one on the “Receive/Send” section.    

If you need to generate a wallet address follow the instructions on this page. Benefit from crypto trading. Create multiple wallets for different currencies

 The 3D Secure authentication is an additional fraud prevention scheme. After you enter your credit card details on a payment page, a new window will appear, requesting for your personal security code. Your financial institution will authenticate the transaction within seconds, as well as confirm that you are the individual making the purchase. Usually it means that your bank sends you an SMS with a one-time password which is entered in order to confirm your transaction.    

When you make a deposit with a bank card at our crypto trading platform, 3D secure authentication is used to protect your transaction. The process described in detail on this page

 Unfortunately, all transactions broadcasted to the blockchain are irreversible. Once your coins are sent, it is practically impossible to recover them. However, there are some rare situations in which the transaction might fail and the money might be sent back. For example, Bitcoin addresses contain a built-in check code, so it's generally not possible to send Bitcoins to a mistyped address. However, if the address is well-formed but no one owns it, any coin sent to that address will be lost.    

Is it possible to send Bitcoin to a mistyped address? Can the money be returned if the address was incorrect? Find the answers on this page

Can I Return Money When Sending Crypto to an Incorrect Address

Incorrect Address

 Crypto transactions depend on a certain number of approvals by the network to be validated. This can take slightly longer or less time than expected. However, you can check the status of your transaction by using the transaction ID on a blockchain explorer such as blockchain.info or etherscan.io  

Sometimes crypto transactions processing can take longer than expected. See the instructions on how to check your transaction status by ID

Crypto Trading Delayed Processing Explained

Delayed Processing

 First, please check if the transaction ID exists in the blockchain, as the wallets might delay the broadcasting. The transaction ID is a string of numbers and letters that you can use to verify your transfer data in the network.  If the transaction already exists in the blockchain, please check whether it has enough confirmations. Different currencies can have different processing times. For example, ETH transactions are normally substantially faster than the BTC ones (several minutes versus up to an hour). If you believe your transaction is taking longer than expected, please contact our Support Team. Please note: for some currencies, such as XRP or XLM, specifying a tag when sending a transaction is mandatory. If the tag is not specified or is specified incorrectly, it will result in your funds being lost.     

Crypto transactions can take some time depending on currency and other factors. See the guide on how to check your transaction status and find a missing crypto deposit

 Web Version – www.cryptology.com  To trade on Cryptology you need to sign up first and then pass the verification process. To do this see a step-by-step How to Get Verified guide and come back. So let’s start trading!    Step 1: click on the "Exchange" tab to get started:    Step 2: next to the price chart you can find the order placement window. There are two main types of orders:  Limit (Limit Order) and Market (Market Order). The main difference between these types of orders is that with a market order, you do not need to manually set the price of the order, and the order itself will be instantly executed at the current price of the asset. To place a market order you need to select the currency and amount you want to buy or sell and click the Buy button (Sell if you would like to sell your assets). The order will be instantly executed at the market price. It is not possible to cancel a Market Order.    Please note, that you should have enough currency on your balance that you want to exchange. If the number of assets is not enough, you will receive a notification when placing an order. You can also check this on the Balances tab.  Step 3: A limit order executes at a selected price, which you need to set manually. In order to place a Limit Order, you need to enter the order volume and the price at which the order should be filled.  The order will be executed when the asset price reaches the specified values. Thus, there is no guarantee that the order will be filled, since the price of the asset may never reach the values you specified.    To cancel a Limit Order, please find the window with your open orders (under the price chart window) and click on the “X” button.     Risk Reminder: Investing in digital assets involves high risks due to large price fluctuations. Before investing, please consider all the risks of investing in digital assets and be careful with your investment decisions.   Mobile app  Step 1: Click on the "Exchange" tab to get started:     Step 2: Let's take a Market order as an example. Select the asset and then enter the amount you would like to buy/sell and click the “Buy”/ “Sell” button. The order will be immediately executed at the market price.   Step 3: To place a Limit Order, select a currency pair, specify the execution price, and order volume and click the “Buy” button (Sell if you are selling).  A Buy Limit Order can only be executed at or below the specified price, and a Sell Limit Order can only be executed at or above the specified price. Thus, there is no guarantee that it will be executed, as it depends on the market price.   There are two ways to cancel a Limit Order:  1. Go to the tab “Exchange” -> “Orders”. Click on the order you are interested in. Here you can see all information about the order: quantity, price, time, and status. You can also cancel the order in this window:   2. Go to the “Exchange” -> “Markets” tab and select the asset you are interested in. Click on the "Open Orders" tab under the price chart. There you can see all the information about your active orders: quantity, price, time, and status. You can also cancel the order in this window in the way described above.   How to check the order history?  Go to the tab “Exchange” -> “Orders”. In this window, you will see information about both open orders and already executed orders.    Risk Reminder: Investing in digital assets involves high risks due to large price fluctuations. Before investing, please consider all the risks of investing in digital assets and be careful with your investment decisions.

 On a highly volatile market, an order might be executed at a price that is different than expected. Let's see an example.   If bid-ask spread on BTC-EUR pair is €3460 by €3469, and you place a market order to buy 1 BTC, you may expect it to fill at €3469. In the fraction of a second, it takes for your order to reach the exchange something may change, or your quotes could be slightly delayed. The price you actually get maybe €3462. The €2 difference between your expected price of €3460 and the €3462 price you actually end up buying at is called slippage.  Slippage refers to the difference between the expected price of a trade and the price at which the trade is actually executed. Slippage often occurs during periods of higher volatility when market orders are used. A market order assures you get into the trade, but there is a possibility you will end up with slippage and a worse price than expected.   Slippage does not directly refer to a negative or positive movement, as any change between the expected and actual prices can qualify. When orders are executed, the corresponding securities are purchased or sold at the most favorable price available. This can cause an order to produce results that are more favorable, equal to or less favorable than original expectations with the results being referred to as positive slippage, no slippage and negative slippage, respectively.

Market Order Executed at a Different Price: Crypto Trading Basics

Why was my market order executed at a different price? 

 Frequently Asked Questions   Definitions:  Cryptology Perpetual Futures Contract: Our Perpetual Futures Contract is a derivative contract bonded to the price of the BTC price index as the underlying.   Index price: the Index Price is the average market price of different exchanges. The exchanges used for the Index Price are independent in order to avoid price manipulation.  Funding Rate: The Funding Rate, determines funds that will be received or marked off every 8 hours at 04:00 UTC, 12:00 UTC and 20:00 UTC.  So we have 3 funding intervals per day. You will only pay or receive the Funding amount if you hold a position at one of these times. If you close your position prior to the Funding Rate exchange then you will not pay nor receive the Funding Rate. When the Funding Rate is positive, longs pay shorts. When the Funding Rate is negative, shorts pay longs. Cryptology does not charge any fees on the Funding Rate amount nor the exchange of it between longs and shorts, the Funding Rate is exchanged directly peer-to-peer. The Funding, is necessary to maintain the contract price close to the Index Price and avoid price manipulation on the exchange.  Mark Price:the Mark Price displays the Unrealized PNL. It is used to calculate the liquidation of the position and avoid price manipulation.   Mark Price = Index Price * ( 1 + Funding Rate * (Time to Funding / Funding Interval))  Open interest: total number of contracts in the order book.   Total balance: overall valuation of clients assets.   Equity: is a sum of total balance and Unrealized PNL.    Available: available assets on balance that could be used for trading.    Initial Margin: the amount that is necessary to enter into a leveraged position.    Maintenance Margin: Maintenance Margin is 50% of the Initial Margin. When your Margin becomes less than the Maintenance Margin, the position will be closed using the liquidation procedure.    Unrealized PNL: PNL that is calculated as a difference of the average price of a deal and the Mark Price.    Realized PNL: Realized PNL is calculated using the average price of opening position and the average price of the closing position.    Est. Liq. Price: it is an approximate price for liquidating the position. If the Mark price touches the Liquidation Price, the position will be liquidated.   Liquidation price: is the price which will be used to close the position in the case of liquidation.    How is the Funding calculated?  Funding Rate = Interest Rate Differencial + Premium Index  Interest Rate Differencial  Let’s suppose that BTC landing rate is 0.03% and USD landing rate is 0.06%, and we have 3 funding intervals per day.  Interest Rate Differencial  = (0.06% - 0.03%) / 3 = 0.01%  Premium Index, Depending on the situation on the market, we determine impact bid price(IBP) and impact ask price(IAP). Impact price is calculated as Volume Weighted Average Price (VWAP) on the market for volume ~10 BTC  Premium Index = (max(0, Impact Ask Price - Mark Price) - max(0, Mark Price - Impact Bid Price)) / Index Price  The Funding Amount is equal to the position value times the Funding Rate.  For example, the Mark Price is 4000 USD. You create a buy limit order (taker fee) at 3:00 UTC of 5000 contracts (contract size: 1 USD) that is ~1.25 BTC.  You will pay a commission of 0.0003125 BTC [(5000*1)/4000*0.01%]  The Funding Rate is 0.01%. At 4:00 UTC the Funding will be charged from your balance.   Funding: -0.000125 BTC [(5000*1)/4000*0.01%]  After the price of BTC changes to 5000 USD and you decide to close part of your position, you would create a market order selling 4000 contracts.   You will also pay a commission of 0.0006 BTC [(4000*1)/5000*0.075%]  The Funding Rate is changed to -0.02%. At 8:00 UTC the Funding will be added to your balance for the remaining position of 1000 contracts .  Funding: +(1000*1)/5000*0.02%=+0.00004 BTC       How is my PNL calculated?  Assume that you bought 500 contracts (contract size: 1 USD) at 3800 USD and then sold by market order 400 contracts at 4000 USD.   As your position was not completely closed part of your unrealized PNL was transformed to realized PLN and the remaining of the position will be maintained as unrealized PNL:  You also made a taker order, therefore, you have to pay taker's fee = 400/4000 * 0.075% = 0.000075 BTC  Realized PNL = 400 * 1 * (1/3800 - 1/4000) =  0,005263157 BTC minus fee  Unrealized PNL = (500 - 400) * 1 * (1/3800 - 1/4000) = 0.0001315789 BTC      What are the applicable fees?  Cryptology has constant trading fees for perpetual futures.   Taker fees: 0.05%  Maker fees: 0.05%    FYI: Maintenance Margin includes commission for closing an open position and also include next funding to reduce the risk of wasting liquidation fund.    What is Cross-Margin?  When you open a position on Cross-Margin, the system will work to maintain your margin above liquidation level by taking funds from your available balance. If there are not enough funds on your account, the system checks if it is possible to cancel active orders that hold margin and cancel these. If both conditions take place, all the open positions are closed at Market Price.  Using Cross-Margin, Leverage is calculated as: Position size/Balance.   NOTE: Currently, Futures on the Android version only supports Cross-Margin. Isolated Margin will be available soon.      What is Isolated-Margin?  When you open a position on Isolated-Margin, the system will liquidate your position when it reaches liquidation level automatically. It will not take funds from your available balance, nor affect other open positions.  Using Isolated-Margin, you can fix the leverage you would like to use. The Margin will be calculated as: Position Size x Leverage.  NOTE: Currently, by default, the web version opens the position on Cross-Margin. If you wish to change this, you will need to drag the leverage forward towards x100, you will then see "Isolated" instead of "Cross".    What is the Insurance Fund?  Cryptology offers 100x leverage for Perpetual Futures Contract on Bitcoin, this is a highly volatile financial product. These two factors cause a high risk of default. To cover possible obligations of one trader to the others, we decided to create an Insurance Fund. The Insurance Fund is used according to the discretion and risk management policy of Cryptology. When opening a position, the trading system calculates two prices, the Liquidation Price and the Bankruptcy Price.   Depending on the size of the position, liquidity and market volatility, the actual average Liquidation Price could be even worse than the Bankruptcy Price. In these cases, losses concerned with the market condition will be covered from the Liquidation Fund. If there are not enough funds to cover losses of liquidation then the system automatically goes to Auto-Deleveraging Liquidation. In the opposite case, if the actual average Liquidation Price is better than the Bankruptcy Price, these funds will go to the Liquidation Fund.    What is Auto-DeLeveraging (ADL)?  Auto deleveraging is a procedure on the market when it is necessary to cover losses of some traders but there are not enough funds in the Liquidation Fund. In this case, the most profitable positions on the market will be automatically closed to cover losses.    Withdrawals:  Futures' withdrawals are processed everyday only one time per day at 10:00 UTC.   Processing time may take up to 2 hours.  Submit your withdrawal request by 10:00 UTC to be included in the same day's batch.

 How to trade futures on Cryptology?  Trading futures contracts on Cryptology is not as difficult as it might seem at first glance, but be careful, as futures trading carries more risks than trading on the spot market. If you already have a verified Cryptology account, you will be able to start trading futures in the next few minutes.  Before trading, it is desirable to understand the basic terms that are used in the futures market. Below are the basic terms you will need to understand the futures market.   Futures are contract agreements to buy or sell assets in the future for a set price. When you make a futures contract, you do not buy the asset itself since the futures contract is a derivative. Hence the main difference between the futures market and the spot market: on the spot market you purchase and own the asset, but futures trading works in another way - you take a position on an asset without actually owning it.  Leverage is one of the most important tools in futures trading. Leverage allows you to maximize the profit. For example, to buy 1 BTC on the spot market, you will need tens of thousands of dollars, depending on market prices. Let's say the current price of Bitcoin is $15,000, so you need $15,000 to buy 1 BTC. A futures contract allows you to open a futures position on an asset by paying only a fraction of its cost. This is possible only with leverage. The more leverage, the fewer funds you need to invest in a position, but the higher the risk of liquidation of your position will be. For example, with x10 leverage, you do not need the entire amount ($15,000), but only $1,500 to buy a 1 BTC contract. Leverage is not available in spot trading.  Position "Long" - purchasing an asset in anticipation of a further increase in the price of the asset. Can be compared to buying. Long traders or buyers are called “bulls”. The name of the growing market - is “bullish”.  The “Short” position is an entry into a deal in anticipation of a further decrease in the price of an asset. The “short” mechanism is more complicated and difficult to understand. In simple terms, you borrow an asset from the exchange and then sell it at the current price. When the price goes down, you buy the asset and return it back, and take the difference between the prices as your profit. Currently, this process is automated and happens instantly, so you do not need to borrow an asset from the exchange and sell it yourself. On our platform, you just need to open a position, and the system will do every step automatically. Short traders (or sellers) are commonly referred to as “bears”. This is why a down market is called a bear market.  Position liquidation. The most unpleasant term for every trader. Liquidation is the forced closure of a position due to insufficient maintenance margin for the position. The higher your leverage and the lower your maintenance margin, the higher the risk of liquidation of your position. You can find the rest of the futures market terms in our Futures Trading FAQ article.   You can find the instructions on how to start trading on Futures below:   First of all, you need to deposit funds to the Futures balance of your Cryptology account. There are several ways to do this: you can make a deposit to the address of your Futures wallet, and also you can transfer funds from your exchange wallet to the futures one. There are two Base assets available for trading on Futures: USDT and BTC.    Go to the Futures page:     Choose the leverage for your Futures position. To do this, click on the "Cross" button and select the leverage:    Select the type of position you would like to open (long or short), order type, and enter the position size. You can open a position both at the market price and at the price of a limit order.  There are two additional types of orders in the futures market: Stop Market and Stop Limit. A Stop Market order is triggered by a stop price. When the stop price is reached, this order becomes a market order and the position closes at the current price. A Stop Limit order is a conditional order that is executed at a specified limit price after the stop price is reached.  The difference is that once the stop price is reached, an order will be placed at the limit price.    Open a position and earn a profit!    Risk Reminder: Futures Trading is a high-risk instrument, it can both maximize your profits through the use of leverage, and lead to serious losses. Before trading futures, you should develop a trading strategy.

The system is peer-to-peer, and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain. Since the system works without a central repository or single administrator, bitcoin is called the first decentralized digital currency. Besides being created as a reward for mining, bitcoin can be exchanged for other currencies, products, and services in legal or black markets. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment. According to research produced by Cambridge University in 2017, there are 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.

ETH works as a platform for numerous other cryptocurrencies, as well as for the execution of decentralized smart contracts.  Ethereum was first described in a 2013 whitepaper by Vitalik Buterin. Buterin, along with other co-founders, secured funding for the project in an online public crowd sale in the summer of 2014. The project team managed to raise $18.3 million in Bitcoin, and Ethereum’s price in the Initial Coin Offering (ICO) was $0.311, with over 60 million Ether sold. Taking Ethereum’s price now, puts the return on investment (ROI) at an annualized rate of over 270%, essentially almost quadrupling your investment every year since the summer of 2014.  The Ethereum Foundation officially launched the blockchain on July 30, 2015, under the prototype codenamed “Frontier.” Since then, there have been several network updates — “Constantinople” on Feb. 28, 2019, “Istanbul” on Dec. 8, 2019, “Muir Glacier” on Jan. 2, 2020, “Berlin” on April 14, 2021, and most recently on Aug. 5, 2021, the “London” hard fork.  Ethereum’s own purported goal is to become a global platform for decentralized applications, allowing users from all over the world to write and run software that is resistant to censorship, downtime, and fraud.

The protocol supports tokens representing fiat currencies, cryptocurrencies, commodities, and/or other assets.  Ripple was created as an alternative payment method for the banking system, and not as an alternative to fiat money and the traditional banking system.  Ripple's main customers are banks using the current software solution for cross-border payments with the ability to track transfers in real-time. Ordinary users can also use Ripple's digital currency for mutual settlements.

A hard fork is, in fact, a blockchain divided into two parts, each of which becomes its own cryptocurrency with its own unique blockchain.  Unlike a soft fork, which is an update of the blockchain, where only one of the separable parts of the blockchain remains valid. Thus, when the fork happens, anyone who holds BTC will receive the same amount of BCH.  The formation of BCH occurred as a result of disagreements within the BTC community. Groups of BTC miners and developers were concerned about its scalability, and they were not sure about the blockchain's plans to adopt segregated witness (SegWit) technology.  These groups believed that although it was necessary (with the increasing size of the BTC network, the blockchain could barely cope with the increased transaction volumes), this proposed update did not correspond to the decentralized philosophy of Satoshi Nakamoto. As a result, they agreed that the only way to overcome the scalability problem is to increase the maximum block size.  Therefore, a hard fork was proposed in which the BTC blockchain will be divided into two parts. One of them will process more transactions at a faster rate than BTC. That's how BCH appeared.

When it was released in July 2014, one of its goals was boosting financial inclusion by reaching the world’s unbanked — but soon afterward, its priorities shifted to helping financial firms connect with one another through blockchain technology.  The network’s native token, lumens, serves as a bridge that makes it less expensive to trade assets across borders. All of this aims to challenge existing payment providers, who often charge high fees for a similar service.  Stellar is unique because every transaction costs just 0.00001 XLM. Given how one unit of this cryptocurrency only costs a few cents at the time of writing, this helps ensure that users keep more of their money.  Few blockchain projects have managed to secure partnerships with big-brand technology companies and fintech firms. A few years ago, Stellar and IBM teamed up to launch World Wire, a project that allowed large financial institutions to submit transactions to the Stellar network and transact using bridge assets such as stable coins.  Although other blockchains have community funds, meaning that grants can be given to projects that help further the ecosystem, Stellar allows its users to vote on which ventures should be given this support.

To learn more about this project, check out our deep dive of Litecoin.  The cryptocurrency was created based on the Bitcoin (BTC) protocol, but it differs in terms of the hashing algorithm used, hard cap, block transaction times and a few other factors. Litecoin has a block time of just 2.5 minutes and extremely low transaction fees, making it suitable for micro-transactions and point-of-sale payments.  Litecoin was released via an open-source client on GitHub on Oct. 7, 2011, and the Litecoin Network went live five days later on Oct. 13, 2011. Since then, it has exploded in both usage and acceptance among merchants and has counted among the top ten cryptocurrencies by market capitalization for most of its existence.  The cryptocurrency was created by Charlie Lee, a former Google employee, who intended Litecoin to be a "lite version of Bitcoin," in that it features many of the same properties as Bitcoin—albeit lighter in weight.

To learn more about this project, check out our deep dive into Axie Infinity.  Inspired by popular games like Pokémon and Tamagotchi, Axie Infinity allows players to collect, breed, raise battle, and trade token-based creatures known as Axies.  These Axies can take various forms, and there are more than 500 different body parts available, including aquatic, beast, bird, bug, plant and reptile parts. Parts from each type class come in four different rarity scales: common, rare, ultra-rare, and legendary — and Axies can have any combination of body parts, making them highly variable and often rare and unique.  Each Axie is a non-fungible token (NFT) with different attributes and strengths and can be entered into 3v3 battles, with the winning team earning more experience (exp) points that are used to level up an Axie's stats or evolve their body parts. These Axies can be bred together to produce new and unique offspring, which can be used or sold on the Axie marketplace.  The Axie Infinity ecosystem also has its own unique governance token, known as Axie Infinity Shards (AXS). These are used to participate in key governance votes and will give holders a say in how funds in the Axie Community Treasury are spent.

Zcash is based on Bitcoin's codebase. It shares many similarities, such as a fixed total supply of 21 million units.  Transactions can be "transparent" and similar to bitcoin transactions in which case they are controlled by a t-addr, or they can be "shielded" and are controlled by a z-addr. A shielded transaction uses a type of zero-knowledge proof called zk-SNARKs, which provides anonymity to the coin holders in the transaction. Zcash coins are either in a transparent pool or a shielded pool. As of December 2017 only around 4% of Zcash coins were in the shielded pool and at that time most cryptocurrency wallet programs did not support z-addrs and no web-based wallets supported them. The shielded pool of Zcash coins was further analyzed for security and it was found that the anonymity set  can be shrunk considerably by heuristics-based identifiable patterns of usage.  Zcash affords private transactors the option of "selective disclosure", allowing a user to prove payment for auditing purposes. One such reason is to allow private transactors the choice to comply with anti-money laundering or tax regulations. "Transactions are auditable but disclosure is under the participant's control. The company has hosted virtual meetings with law enforcement agencies around the U.S. to explain these fundamentals and has gone on the record of saying that "they did not develop the currency to facilitate illegal activity".  While miners receive 80% of a block reward, 20% is given to the "Zcash development fund": 8% to Zcash Open Major Grants, 7% to Electric Coin Co., and 5% to The Zcash Foundation.
