    SPARTA is a new cryptocurrency that uses blockchain technology and was created by a team with 3 years of cryptocurrency experience and 6 years’ experience managing large projects. The team has united behind the idea of creating a new society of free and happy people.

    The name SPARTA is derived from the words: “SPArk” + “Target”. SPARTA is a new spark in the cryptocurrency world. We seek to represent progress, development and forward movement. Our spark is “targeted” at creating new financial relations that are decentralized, honest, and fair.

    SPARTA cryptocurrency is also named after the eponymous state in ancient Greece. Sparta exemplified the ideal state described by the philosopher Plato. We want to make SPARTA cryptocurrency as simple and clear as possible. Like the ancient Spartan city-state, SPARTA is striving to be ideal, but in the world of cryptocurrencies.

    Our slogan: “Simple. Fast. Reliable”
    “SPA” is the abbreviation for SPARTA tokens.

    Features and Characteristics:

    - The fee is as low as possible and changes depending on the amount of time that has elapsed since the launch. It was introduced solely for the purpose of protecting against spam transactions.
    - Forging and proof-of-stake. The operation of the network can be supported by ordinary computers.
    - Worthwhile reward for forging. A miner who creates a block is rewarded with the sum of all the transaction fees in the block. If certain conditions are satisfied, a miner also receives a guaranteed reward in the form of newly created SPA tokens.
    - The reward per block changes every 500,000 blocks. The initial reward is 8,000 SPA for each block.
    - To protect against malicious users, tokens affect the ability to create blocks only one day after they have been credited (1,440 blocks).
    - Protection against 51 % attacks, nothing-at-stake attacks, and other malicious actions.
    - Transactions are deemed safe after 10 confirmations (10 minutes).
    - Blocks are generated once per minute.
    - There are 888 transactions in 1 block.
    - The network capacity is as follows: 14.7 transactions per second; 888 transactions per minute; 53,280 transactions per hour; and 1,278,720 transactions per day.
    - The total number of tokens will be 8,888,888,888 (~ 9 bln). Of these, 10% or 888,888,888 (~ 900 mln) are part of the premine. All coins will be issued for circulation on stock exchanges, and the proceeds will go toward growing the cryptocurrency.
    - The issue will not end before 2025.
    - A mnemonic seed (mnemonic phrase), a set of several unrelated words, is used to generate the address.
    In the SPARTA network, addresses start with “SPA”. For example, SPA1APoGEhZF6spoqniQn8rBVAz2WgNoaUuw
    - Apella (APL) is the smallest fractional unit of the cryptocurrency, equal to one 100 millionth (0.00000001).

    Forging:

    Create a wallet: SPARTA Web Wallet
    Download the forging application: https://sparta.top/sparta-1.0.0.jar

    SPARTA uses the proof-of-stake concept, which means that account balances are used for forging instead of computing power (as is the case with mining based on proof-of-work). SPA tokens (coins) are used instead of processors and video cards.

    To start forging:

    1. Create a SPARTA wallet and deposit SPA tokens in your account. A minimum of 888 tokens is required to start forging.
    2. Run the special application on your computer. After the application is started, it automatically begins supporting the SPARTA network. When a block is created successfully, you receive a reward.

    The chances for creating a new block are distributed among all network participants based on a special formula depending on the balance amount at their addresses. The more SPA tokens in the account, the more chances to create a block.

    The reward for creating a block depends on the number of coins in the user account:

    - If a miner has between 888 and 999,999 SPA (inclusive) in the account, he or she receives only with the sum of transaction fees.
    - If the miner has SPA 1,000,000 or more in the account, he or she receives with the sum of transaction fees and newly created SPA tokens.

    Thus, miners in the first category support the network, but miners in the second category also help the cryptocurrency grow by investing at the initial stage. Accordingly, these miners get more profit.

    To avoid centralization, all miners with balances of 1,000,000 SPA or more have the same changes of creating a new block. That is, if one miner has SPA 1,000,000 and another has SPA 25,000,000, their chances of creating a block are the same.

    Miners who have more than SPA 1,000,000 are recommended to divide their coins and forge on different servers and in different locations — countries, cities, etc. Doing this is much more useful for the SPARTA network. The SPARTA network automatically tracks and punishes unscrupulous miners using several computers with balances over 1,000,000 SPA in a single location to enrich themselves rather than develop the network.

    A new block is created every minute. So a miner gets a chance to create new SPA tokens every 60 seconds. The reward for a block changes depending on the total number of the blocks created (i.e. based on the elapsed time).

    Check out our website on SPARTA - Simple. Fast. Reliable for more details on the reward for a block.

    Vision:

    Our goal is to launch a new stage in the evolution of cryptocurrencies. SPARTA will let cryptocurrency technology more easily and quickly become part of our lives in order to create new financial relations that are decentralized, honest, and fair. This is the future we see!

    With its clear advantages, SPARTA technology will bring cryptocurrencies to a whole new level. All of its benefits, convenience, and simplicity make it easy for everyone to use digital money. People can use SPARTA to gain independence from banks and easily make money from home.

    In time, people will recognize the advantages of SPARTA cryptocurrency over conventional money and will begin to use it widely. As a result, financial relations in society will change radically and become honest and fair. Accordingly, the whole world will become honest and fair. This is the ultimate goal we are pursuing!

    Road map:

    - Listing on exchanges and p2p platforms.
    - Listing on cryptocurrency monitoring websites (coinmarketcap.com)
    - Forging calculator.
    - Desktop wallet:
    -- MacOS,
    -- Linux,
    -- Windows,
    -- Chrome OS.

    - Localization of the website, wallet, and blockchain explorer into 11 languages.
    - Creation of a compiled node for all operating systems:
    -- Windows,
    -- MacOS,
    -- Linux,
    -- Chrome OS.

    - Real-time network graphs and statistics.
    - Wallet for mobile devices:
    -- Android,
    -- iOS,
    -- Windows,
    -- Blackberry.

    - Creation of our own hardware wallet or support for existing hardware wallets.
    - nLocktime transactions. They can be used and confirmed by the network only after a certain period of time. This is very convenient for decentralized exchanges.
    - Multiple signatures are an additional protection against scammers who try to steal wallet data to perform a transaction. A network participant can specify several other network trusted participants. When a transaction is created from the participant’s address, his or her proxies will receive a request to confirm or reject the transaction. In other words, transactions will not be approved without their permission. You decide whether your wallet requires multiple signatures.
    - Ability to use several addresses (hd-wallet) for one wallet. BIP-31/BIP-44.
    Dynamic block resizing to support network scalability without a hard fork.
    - Ability to dynamically change the block generation frequency, so that network scaling, if necessary, will not require a hard fork.
    - Ability to dynamically change the number of transactions in 1 block, so that network scaling, if necessary, will not need a hard fork.
    - Local exchanges/offices to exchange cryptocurrency, job positions for promoting cryptocurrency through seminars and presentations.
    - Creation and operation of crypto-ATMs.
    - Development of a mini-computer with an automatic update system to serve as a home node.
    - Our own cryptographic wallets that can be used to withdraw and deposit fiat money through crypto-ATMs all over the world.
    - Support for VISA/MasterCard cards. The card balance will be displayed in SPA. But if the account holder wants to withdraw cash, funds will be converted automatically to fiat currencies at the current exchange rate. Such cards will be especially helpful in low-income countries with unstable national currencies, whose residents lack bank accounts.
    - Advertising platforms that award an SPA for guessing the CAPTCHA or performing some other action, similar to Bitcoin faucets, which give out a few Satoshi for comparable actions.
    - Popularization and introduction of cryptocurrency not only on exchanges, but also in other areas.
    - Software for “paper” wallets.
    - Atomic cross-platform transactions (swaps) between cryptocurrencies.
    - Additional network to safely synchronize and update wallet settings.
    - Ranking among the top 100 cryptocurrencies.
    - Preparation of other promotional materials, including 2 videos on cryptocurrency: a promo and technical details.
    - Creation of a .onion site and a node for the TOR browser.
    - Smart contracts and smart assets.
    - Crowdfunding for systems using SPA.
    - ICO platform using SPA.
    - Blockchain-based platform for decentralized peer-to-peer lending.

    How SPARTA can solve today's problems

    We are trying to identify the best of what has been created and apply it in our operations. SPARTA can solve many problems. For example:

    - SPARTA allows everyone to access financial services regardless of their location and without having to get someone's permission.

    - People, not banks or other financial institutions, remain in control of their own funds.

    - Blockchain technology can help resist political tyranny by introducing decentralized cloud-based functions that were previously controlled exclusively by official organizations.

    - Many branches of the economy will be able to escape excessive regulation and licensing requirements imposed by hierarchical structures, lobbyists, and special interest groups. This will help create new business models that are not burdened by unnecessary intermediaries.

    - Blockchain-based records of all transactions and the inability to change these records may become the foundation for societal progress.

    - Each asset in the blockchain is coded with a unique identifier used to monitor, control, exchange, sell, or buy the asset.

    - Due to its economic, political, humanitarian and legal advantages, blockchain technology is becoming a powerful breakthrough capable of fundamentally changing most aspects of society.

    Description of SPARTA's main advantages:
    Blockchain technology


    The SPARTA cryptocurrency is built on blockchain technology. This is an enormous ledger that is available to everybody and that cannot be altered. It contains encrypted information about all transactions in the SPARTA network.

    A blockchain consists of a chain of inseparable blocks (the pages of this enormous ledger). Each block contains transaction information. Each transaction is verified before it is added to the blocks. In other words, a block represents a group of several transactions.

    Moreover, each block always links to the previous block. This means that each block contains encrypted information about the previous block, which means that it cannot be replaced or counterfeited. If an attacker tries to somehow replace an already-confirmed block in the middle of the chain with another block, the blockchain simply will not accept it. Why? Because it will always be different than the block that is being replaced and to which all other blocks are linked.

    In the SPARTA network, a new block consisting of 888 transactions is created each minute. Accordingly, it takes one minute to confirm a transfer in the SPARTA network. During this time, the transaction is verified and added to the blockchain.

    The SPARTA network is decentralized and new blocks are created by the users themselves. The block information is available to everyone. The blockchain technology makes it easy to verify the authenticity of each payment, and cryptocurrency cannot be counterfeited or hacked. Furthermore, governments and corporations cannot influence the operations within the system.

    Description of SPARTA's main advantages:
    Transfers at any time to any part of the world


    Unlike bank transfers, operations with cryptocurrencies are executed 24 hours a day, 365 days a year. You decide for yourself when, to whom, and where to send money. There are no limitations here.

    With the SPARTA cryptocurrency, you manage your own funds. There is no need to ask your bank for permission to use them. Nobody can freeze your account or block a transfer to someone from a particular country or region.

    Suppose that in the middle of the night Ravi from India wants to make a transfer to his friend Ben in Australia:

    • With fiat money, Ravi would have to wait until morning, go to the bank, stand in line, fill out forms, pay a huge fee (likely at least 10% of the transfer amount), and then wait 3-5 business days for Ben to get the money.

    • With SPARTA, in the middle of the night Ravi can immediately send SPA tokens, which Ben will receive after 1 minute.

    So if you need to send money to someone in another country, you can do it quickly, without paying huge fees, and without filling out piles of forms.

    Description of SPARTA's main advantages:
    Security


    To secure the SPARTA network from attackers, the cryptocurrency uses a host of security techniques. Here are the 4 most important:

    • Attackers cannot transfer tokens from one account to another in order to boost their chances of creating new blocks. Tokens affect the ability to create blocks only after 24 hours have passed since they were credited (i.e. 1440 blocks have been created).

    • A transaction is considered safe after it has received 10 confirmations (10 minutes). Thus, an attacker would have to generate 10 consecutive new blocks and simultaneously have an enormous account balance. This situation is likely only if the attacker already possesses more than 90% of all funds in the network, which is virtually impossible.

    • The SPARTA network is inherently protected from 51% attacks thanks to its use of the Proof-of-Stake concept. Unlike cryptocurrencies that use Proof-of-Work, an attacker cannot create longer chains by out-computing other users in the network.

    • Attackers cannot resort to Nothing-at-Stake attacks, because the SPARTA network only allows the last 720 blocks of the chain to be altered. Any block placed below this threshold is automatically rejected.

    Description of SPARTA's main advantages:
    Convenience and accessibility for all


    The SPARTA website and wallet are as user friendly as possible. The features are simple. Anyone can figure out how to use them. SPA can be exchanged at any time for fiat money through exchanges or trading platforms. You can do this now on the SIGEN.pro platform, BTC-Alpha exchange or through the built-in exchange on our website SPARTA - Simple. Fast. Reliable.

    So if you want to buy SPA, you can do so in a few clicks. And if you need money to buy stuff, you can easily trade SPA for fiat money or other cryptocurrencies. And you can do whenever you want.

    Moreover, the SPARTA network has no social, national, government, religious, political, or gender limitations. It doesn't matter how old you are, what you do for a living, or what your level of education is. You don't need to study at a university, pass exams, or get a license. SPARTA is available to everyone.

    SPARTA is used with equal success by people from countries around the world regardless of their gender, nationality, religion, social status, or political views. Cryptocurrency users are a diverse group with entirely different interests and traits. SPARTA equalizes the rights of all users and unites them in what matters most: building free, honest, and fair financial relations.

    Description of SPARTA's main advantages:
    Proof-of-Stake


    Bitcoin and most other cryptocurrencies use the Proof-of-Work (PoW) concept. This was the very first technique used, and it happened to bring a lot of issues with it. However, SPARTA uses Proof-of-Stake (PoS), so here this process is called forging, not mining. What's the difference?

    • In the case with Proof-of-Work, mining requires considerable and expensive computing power as well as huge monthly electricity costs. In search of profits, miners keep buying powerful specialized hardware that costs a huge amount of money. Miners began to pool their powerful resources, thus pushing ordinary people out of mining. This leads to centralization, which cryptocurrency was specifically designed to fight against.

    • In the case with Proof-of-Stake as a forging tool, the user account balance is used instead of computing power. SPA tokens (coins) are used instead of processors and video cards. Each token is a forging tool. Thus, forging is more convenient and simpler than traditional mining, because a regular computer is powerful enough. As a result, this method is available to ordinary people and does not promote centralization.

    In the SPARTA network the probability of creating a new block is distributed among all network participants using a special formula that depends on their addresses balances. The more SPA tokens are in an account, the greater the chances of creating a block and receiving a reward.

    Description of SPARTA's main advantages:
    Protection against inflation


    Nobody can create an unlimited number of SPA. The same can't be said about dollars. There are no printing presses here. National currencies lose 1-20% of their value (sometimes more) each year. But SPARTA, like gold is backed by a limited volume. An arbitrary number of SPA tokens cannot be printed. This protects the network from inflation.

    Tokens will be produced solely through the forging process until the maximum quantity of 8,888,888,888 (~9 billion) coins are produced. Then production will cease. This will take place no earlier than 2025.

    The cryptocurrency exchange rate is governed only by the market. Because SPARTA has so many advantages over banks and other cryptocurrencies, and because cryptocurrencies as such are constantly becoming more popular, the SPA exchange rate is also expected to grow.

    The dollar and other fiat money is subdivided into hundredths (a minimum of 0.01 USD, i.e. one cent), but the SPARTA is subdivided into millionths, i.e. Apella (1 Apella = 0.00000001 SPA).

    Thus, people will always be able to buy and use SPA at any exchange rate. Even if SPA coins become worth 1 million USD each, people will still be able to buy a certain amount of SPA for 1 cent.

    What is a transaction?


    Transactions are the only way SPARTA addresses can alter their balances. Each transaction performs a single function. A record of the transaction is permanently stored on the network once it has been included in a block.

    In short, a transaction is transfer of SPA from one address to another. When a SPARTA network participant carries out a transaction, it gets into a transaction pool along with all other new transactions of network participants.

    All SPARTA transactions are considered unconfirmed until they are included in a valid network block. When a block with a transaction is included in the blockchain, it becomes a transaction with one confirmation. As a rule, once the transaction has been sent, it goes from the pool immediately to the block. As blocks on the SPARTA network are created every minute, in most cases a transaction needs only 1 minute to get the first confirmation.

    As subsequent blocks are added to the existing blockchain, each transaction receives new confirmations from each of the added blocks. On the SPARTA network, each transaction is deemed safe after 10 confirmations. If for some reason the transaction is not included in the block before its deadline (24 hours), it is removed from the transaction pool.
    For more information about transactions see our Whitepaper

    Is there a risk of faking SPARTA transactions?

    SPARTA network operates in such a way, that it is just impossible to fake any transaction. Each of them has a unique digital signature. And any attempts to commit any fraud, such as sending two similar transactions, will be terminated. Transactions created as a fraud simply cannot be accepted by the blockchain.

    For example:

    Mark transferred 1000 SPA to Lesley.

    • When Mark made the transaction, there was an automatic signature of Mark attached, which proves that SPA were sent by him. Such transaction can be accepted by the blockchain.

    • But here come evil user Steve and tried to fake a transaction by indicating that Mark sent 1000 SPA not to Lesley’s wallet but to Steve’s. But to the disappointment of Steve there was no a unique signature of Mark attached to that transaction, and blockchain simply denied it.

    There is a theoretical possibility of the SPARTA network attacking with the purpose of repeating of the transaction, to return coins to another address, but after going through 10 confirmatons to succeed with any attack aimed to transaction editing will be just impossible. In other words, if a transaction has 10 confirmations, it can not be repeated. It is considered to be safe and complete.

    What is a digital signature and where does it come from?


    Each transaction contains a unique digital signature that confirms that the transfer was made specifically by the sender, not someone else.

    The digital signature is generated from the private key which belongs to the owner of SPA coins and invisible for anyone. The signature is encrypted and attached to the transaction. It is a proof the the transaction is valid and was created specially by the sender.

    • It is impossible to counterfeit the digital signature if one doesn't know the private key.
    • The private key is generated from a mnemonic phrase which only you know

    • All information uses the cryptographically secure SHA 256 hash algorithm, therefore the digital signature or private key cannot be counterfeited without a mnemonic phrase. This is why it is crucially important to keep it in secret

    Why are all SPARTA transactions pseudonymous?

    As all you need to check the validity of a transaction is its digital signature, all transactions are anonymous More accurate to say they are pseudonymous.

    The recipient and the SPARTA network can see only the address of the public key but it is not known who the address belongs to. For instance, Mark sent 1,000 SPA to Lesly. The network shows only their addresses - a set of letters and numbers. No one can see that the sender’s name is Mark or the recipient is Lesly.

    Therefore, no one can your personal data unless you say about it. And since anyone can create several wallets, you can make any information confidential.

    For example, Lesly knows Mark’s wallet address, but Mark can create a new one and no one will know the new address belongs to him unless he himself tells anybody about it.

    What is the fee in the SPARTA network charged for?


    Each transaction in the SPARTA network requires a fee. But compared to bank and other cryptocurrencies commissions, it is the lowest.

    The fee is required solely to protect the network from DDoS attacks, unlike in Bitcoin, for example, where the fee serves as a means for miners to generate profit.

    Take, for example, Steve, a malicious network user:

    • Steve has two addresses in the SPARTA network and transfers coins between them back and forth.
    • He endlessly sends 1000 SPA from one wallet to the other one and then back.
    • Each transaction is repeated and gets into blocks though all this has no sense.
    • Doing so, Steve creates an additional load on the network.
    • Having to pay a fee for each transaction, Steve won’t do this.

    The fee protects the system from the described attacks. Charging a fee for a transaction is a necessary measure but we make the fee as low as possible so that users just ignore it.
