ARCS Tokens That Are Issued To Make Construction Faster

About ARCS

ARCS is essentially a token that depends on the Ethereum platform. Nonetheless it, the Ethereum Platform Running Situation Will Positive Its Limit, Which Has Provoked a Warning About its Possibilities in the Future. Of course, There Are Still Great Possibilities to Enhance the Situation. However, We Are Thinking about Republishing ARC Using A Platform That Is Potential And Very Scale On the subject of the Present Platform.

Overall, we will not only issue payment tokens that have decided Features, but also we will issue governance tokens, which are devoted to world Control, and security tokens that are appropriate for regionality. We will do our best to develop ARCS because it will contribute to the new world.

ARCS Vision

This Allows Agencies To Buy And Promote Files While Complying With Personal Statistics Guidelines, Eventually Bettering Their Info Analysis Knowledge And Gaining Significant Insights. Individuals who provide files to info banks will be safe by a high level of privateness and accept prizes primarily based on entering facts and it's used.

Files Purchases and Income Are Increasingly Turning into The Main Part of Our Lives, the Proposed Aire Atmosphere Will Make Info Purchases and Revenue an Included Part of Our Lives While Ensuring Privateness and Fair Trade Knowledge Distribution.

Demanding situations With Personal Data

In the last few years, personal files have to emerge as increasingly fragmented across a variety of different services and often are living in databases without proper user approval. This Leaves Clients Without Proper Control Of Their Facts And, To Some extent, Their Id. European General Records Protection Policies (GDPR) Are Taken Into EU Law To Resolve This Problem. But it surely, the Brand Still Collects Large Volumes of Personal Files for Analysis and Monetization.

Files Are Often Defined As "New Oil" And Clients Quickly Emerge as Aware Of Its Value. This Has Expanded In Some Statistics Banking Enterprises That Attempt To Buy Facts And Promote For Profit, But Usually By Taking into account The Hobbies Of Large Organisations. AIre Is Built With Mechanisms To Provide A Fairer Distribution of Gains From Personal Info By Giving Customers a Sovereign Identity.

ARCS Solution

ARCS Solves Problems of Inefficient Info Use. Currently, Each Brand Only Stores and Uses Part of the Files Customers Leave Online. Due to this fact, Complete and Accurate User Profiles can't be collected. Clients Basically Have Negative Comments On The Existing Use Of Their Info Because The Knowledge And / Or Directions They Impediment Because That Is Used Is Often Incorrect.

To Resolve This Problem, AIre Enables Incorporated User Info Control That Enables Info To Be Used With Consent And Statistics Rights Secure. We Find the money for That This Mechanism Can Provide A Wide Variety Of Application Services For Clients. We Refer To Interfaces That Can Offer This Service As "The Next Era Bank". Next Iteration Bank Is a Comprehensive Electronic Pockets Very true for the Future Era of Email correspondence Transformation.

A Single Service Provider Will Not Provide All Services And Every Service Provider Will Provide Their Services As Part Of The Next Era Bank Using A Single Token. The Next New release Bank Is A Virtual Pockets That Handles This Service. AIre Tokenizes Valuables As Security Tokens Through Statistics Banks, Such As Shares, Real Property, Art, Etc., Make Funds / Transfers Using Cryptocurrency. Further Details Are Defined in the "Future Building Phase.

ARCS Uses This Records To Create New Evaluation Standards. In addition to ensuring compatibility with other engaging organizations on the AIre platform, AIre will take the initiative to settle down new applied sciences and thoughts regarding user facts administration to come to be a true "user sovereign" platform.

Market Size

ARCS Concentrating on A considerable number of Markets, Two Major Markets Are Records Trade Market, AIre Knowledge Banking Initiative Will Target This Market; And the Financial Refugee Market, As Defined in the "Future Growth Area. To Give An Example, Decentralized Decentralized Email correspondence Id (DID) Infrastructure Can Be Advanced By Leveraging Files That Is Secrets In Statistics Banks. As a result, it is possible to target people who do not have a bank account that does not have access to financial markets because they do not currently have an electronic identity.

ARCS function

ARCS consists of three main Brush off Data Enter, Records Storage, and Records Usage. Statistics Banks Are The Core Of The Device For Storing Information, And The API Enables Facilitation And Orchestration Of Info Waft. AIre Can Cool down Different Information Sources And Manage Knowledge Possession, For example, Fragmented Info From A religious Sources Can Be Related To The Identification Of Professional Customers At The Info Bank. As a result, Clients Can Manage Their Information in One Included Network.

Business model

IF A

IFA will bring together expenses from third parties when they access user info at the files bank. To Attract More Third Parties To Use Information Bank Infrastructure, It Is Pointless To Gather Wider User Statistics. Hence, By Reveal Tokens To Customers As Incentives, Customers Are Intended To Enter Further Information.

Third-party
Third Parties Can Obtain Statistics From Knowledge Banks To Encourage Its Analysis. Bank Knowledge Will Be A Cheaper Alternative Than Classic Information Aggregators And Is Absolutely In Accordance Because Customers Give Approval And Be Rewarded.

User

Clients will be rewarded dependent on the quantity, type, and quality of files they store. Prizes will be distributed every time info is Received, which will encourage clients to enter more useful knowledge into the info bank. Prizes Come As A Cost Token That Can Be Used As A Price Method When Using An ARCS Service Application Provided by a Third Party.

Knowledge Bank Hub Concept

To Make bigger Networks Outside User Info Inputs to Files Banks, ARCS Will Allow Other Facts Markets and Dealers to Participate in Networks. They Will Not Have To Re-Enter Facts Into Knowledge Banks, Instead, They Will Be Able To Offer Existing Information Banks. This Is A "Hub" Idea Where Many Members Can Transact Records To Each Other. The Community Will Boost Its Value Exponentially Because More Knowledge Members Offer Their Information Because Big Knowledge Is Required For Knowledge Analysis To Have Significant Insights.

The Main Purpose of ARCS

Incentives For Users

Many Internet Customers Experience Uncomfortable When Delivering Personal Records to Services Because of Recent Public Experience About Large Organizations Misusing Personal Info. AIre Promises Incentives to Customers for the Info They Provide, which is Envisioned to Cut back Resistance to Store Personal Data.

The Right to Use AIre Services

Economic climate Tokens Are Designed To Make bigger Advised Organically Because Members Will Be given Unique Reward From The Use Of ARCS Tokens That Are Contrary To Fiat Currencies AIre Core Values ​​Are Knowledge Held by Knowledge Banks and ARCS Is a Global Community Currency that Files Buyers Can Use to Buy Data.

Token Flow

Below is an ARCS Token Flow Demonstration:


Users Input Data Into AIre Data Banks And Receive ARCS As Gifts
Companies That Want To Obtain Data From First Bank Data Will Buy ARCS From An Exchange
The Company Can Then Buy Data From Data Banks With ARCS. At The Same Time, Users Will Be Prized For Their Data And IFA Will Collect Commission Fees To Provide Services
The Company Can Utilize Data For Its Services And Offer It To Users In Return For ARCS

ARCS Token

ARCS Are Original Tokens From AIre. This Can Be Owned In A Wallet That Supports ERC-20 Token Standards And Is Traded On Exchanges That Register ARCS. This Will Fluctuate According To Market Conditions.

Create ERC20 Token.

Step 2 - How To Created ERC20 Token?


In the first step, we explained how to design an ERC20 token code. Now we are entering the second stage of How to Make ERC20 Tokens.

Download MetaMask chrome extension to generate a wallet. This is going to be the owner of the smart contract. Alternatively you can always use Mist or My Ether Wallet. For the sake of simplicity let's use MetaMask extension in this project.

Once you download the extension, go ahead and create a new account protected by a password. Then choose "Ropsten TestNet" from the top left corner. Before we deploy the contract to Main Ethereum blockchain, we'll test it against TestNet and make sure everything works as expected. It looks something like this:

Ropsten Test Network

Now head over to Remix Ethereum (an online solidity compiler and debugger) and paste the code you just modified. Ignore any warnings you see. Next go to settings and uncheck "Enable Optimizations" if it's checked.

Now go to "Run" tab and click on Deploy under .

PLUGIN MANAGER

After you press Deploy, MetaMask will ask you to buy several ether tests and send the transaction. It looks like this:

Confirmed MetaMask

Make sure you are on Ropsten TestNet and not on MainNet then press Submit. Now open MetaMask again and click on the first transaction. This will take you to Etherscan where you can observe ongoing transactions. Up to 30s are required to confirm a transaction. Once confirmed, it looks like the following:

TX Etherscan.io
Create Smart Contract

You just deployed your contract. Note the address on the above transaction page. That's your contract address.

Step 3

Add your token to MetaMask. Copy the Contract Address, open MetaMask -> Add Token and Paste the Address. This looks like the following:

ADD Token

Congratulations, you just made an ERC20 token, in TestNet mode. If you have questions, please leave a message in the comments column below. Hope it is useful for you. Thanks.

Update: The Remix IDE has moved to http://remix.ethereum.org. This instance of Remix you are visiting WILL NOT BE UPDATED. Please make a backup of your contracts and start using http://remix.ethereum.org

ERC20 Tokens

How to make your own Ethereum-based ERC20 Token and launch ICO

Lately, I have been digging into blockchain and decentralized applications to educate myself and improve my knowledge. To make the learning process enjoyable, I decided to build my own Ethereum-based token and understand the ICO (Initial Coin Offering) launch process.

This article aims to give you an idea of how smart contracts work at Ethereum by launching a simple ICO demo.

Basics


Here are some basic terms that we will use in this article. If you are familiar with the following concepts, don't hesitate to move on to the next section.
  • ERC20 tokens based on Ethereum: In Ethereum tokens represent tradable items such as coins, loyalty points, etc. You can make your own cryptocurrency based on Ethereum. Additionally, the benefit of following the ERC20 standard is that your token will be compatible with other clients or wallets that use the same standard.
  • Smart Contracts: Smart Contracts are blocks of self-executed code used on the Ethereum blockchain. They contain data & function codes. Contracts make decisions, interact with other contracts, store data and transfer Ether (cryptocurrency units in the Ethereum blockchain) between users.
  • Solidity: Language for writing smart contracts.
  • MetaMask / Mist / MEW Wallet: A digital facility that stores your Ether and Ethereum-based tokens.

Now that you know the basic terminology used in this article, let's get started.

Step 1: Code

Open your favorite text editor and paste the following code:


pragma solidity ^0.4.4;

contract CCA {

    /// @return total amount of tokens
    function totalSupply() constant returns (uint256 supply) {}

    /// @param _owner The address from which the balance will be retrieved
    /// @return The balance
    function balanceOf(address _owner) constant returns (uint256 balance) {}

    /// @notice send `_value` token to `_to` from `msg.sender`
    /// @param _to The address of the recipient
    /// @param _value The amount of token to be transferred
    /// @return Whether the transfer was successful or not
    function transfer(address _to, uint256 _value) returns (bool success) {}

    /// @notice send `_value` token to `_to` from `_from` on the condition it is approved by `_from`
    /// @param _from The address of the sender
    /// @param _to The address of the recipient
    /// @param _value The amount of token to be transferred
    /// @return Whether the transfer was successful or not
    function transferFrom(address _from, address _to, uint256 _value) returns (bool success) {}

    /// @notice `msg.sender` approves `_addr` to spend `_value` tokens
    /// @param _spender The address of the account able to transfer the tokens
    /// @param _value The amount of wei to be approved for transfer
    /// @return Whether the approval was successful or not
    function approve(address _spender, uint256 _value) returns (bool success) {}

    /// @param _owner The address of the account owning tokens
    /// @param _spender The address of the account able to transfer the tokens
    /// @return Amount of remaining tokens allowed to spent
    function allowance(address _owner, address _spender) constant returns (uint256 remaining) {}

    event Transfer(address indexed _from, address indexed _to, uint256 _value);
    event Approval(address indexed _owner, address indexed _spender, uint256 _value);

}

contract StandardCCA is CCA {

    function transfer(address _to, uint256 _value) returns (bool success) {
        //Default assumes totalSupply can't be over max (2^256 - 1).
        //If your token leaves out totalSupply and can issue more tokens as time goes on, you need to check if it doesn't wrap.
        //Replace the if with this one instead.
        //if (balances[msg.sender] >= _value && balances[_to] + _value > balances[_to]) {
        if (balances[msg.sender] >= _value && _value > 0) {
            balances[msg.sender] -= _value;
            balances[_to] += _value;
            Transfer(msg.sender, _to, _value);
            return true;
        } else { return false; }
    }

    function transferFrom(address _from, address _to, uint256 _value) returns (bool success) {
        //same as above. Replace this line with the following if you want to protect against wrapping uints.
        //if (balances[_from] >= _value && allowed[_from][msg.sender] >= _value && balances[_to] + _value > balances[_to]) {
        if (balances[_from] >= _value && allowed[_from][msg.sender] >= _value && _value > 0) {
            balances[_to] += _value;
            balances[_from] -= _value;
            allowed[_from][msg.sender] -= _value;
            Transfer(_from, _to, _value);
            return true;
        } else { return false; }
    }

    function balanceOf(address _owner) constant returns (uint256 balance) {
        return balances[_owner];
    }

    function approve(address _spender, uint256 _value) returns (bool success) {
        allowed[msg.sender][_spender] = _value;
        Approval(msg.sender, _spender, _value);
        return true;
    }

    function allowance(address _owner, address _spender) constant returns (uint256 remaining) {
      return allowed[_owner][_spender];
    }

    mapping (address => uint256) balances;
    mapping (address => mapping (address => uint256)) allowed;
    uint256 public totalSupply;
}

contract CoinCryptoAsia is StandardCCA { // CHANGE THIS. Update the contract name.

    /* Public variables of the token */

    /*
    NOTE:
    The following variables are OPTIONAL vanities. One does not have to include them.
    They allow one to customise the token contract & in no way influences the core functionality.
    Some wallets/interfaces might not even bother to look at this information.
    */
    string public name;                   // Token Name
    uint8 public decimals;                // How many decimals to show. To be standard complicant keep it 18
    string public symbol;                 // An identifier: eg SBX, XPR etc..
    string public version = 'H1.0'; 
    uint256 public unitsOneEthCanBuy;     // How many units of your coin can be bought by 1 ETH?

        fundsWallet = msg.sender;                                    // The owner of the contract gets ETH
    }

    function() payable{
        totalEthInWei = totalEthInWei + msg.value;
        uint256 amount = msg.value * unitsOneEthCanBuy;
        require(balances[fundsWallet] >= amount);

        balances[fundsWallet] = balances[fundsWallet] - amount;
        balances[msg.sender] = balances[msg.sender] + amount;

        Transfer(fundsWallet, msg.sender, amount); // Broadcast a message to the blockchain

        //Transfer ether to fundsWallet
        fundsWallet.transfer(msg.value);                               
    }

    /* Approves and then calls the receiving contract */
    function approveAndCall(address _spender, uint256 _value, bytes _extraData) returns (bool success) {
        allowed[msg.sender][_spender] = _value;
        Approval(msg.sender, _spender, _value);

        //call the receiveApproval function on the contract you want to be notified. This crafts the function signature manually so one doesn't have to include a contract in here just for this.
        //receiveApproval(address _from, uint256 _value, address _tokenContract, bytes _extraData)
        //it is assumed that when does this that the call *should* succeed, otherwise one would use vanilla approve instead.
        if(!_spender.call(bytes4(bytes32(sha3("receiveApproval(address,uint256,address,bytes)"))), msg.sender, _value, this, _extraData)) { throw; }
        return true;
    }
}

The code above uses the Solidity language to build a simple ERC20 token. This code is well commented on and very easy to understand. After you paste the code into your text editor, look for the text: "REPLACE THIS". This is what you need to change based on the characteristics of your token. In the example above, I have named my token CoinCryptoAsia (CCA). Total supply is limited to 1000, but people can have at least 0.000000000000000001 because of 18 decimal places. In addition, the contract owner (the person who executes it) gets all the initial tokens. I have set the ICO price as follows:

1 ETH = CCA 1.000

This means, if someone sends 1 ETH to this smart contract, they will get 1.000 units.
