The day, people started paying for frozen yogurt with crypto

8 years after Laszlo Hanyecz paid 10,000 Bitcoins for 2 PapaJohn’s pizzas, 1,000 participants of the DAHO.AM Pure Tech Conference each paid 300 CrowdstartCoins XSC for conference T-shirts, goodie bags or frozen yogurt. 30 degrees Celsius and more made especially the frozen yohurt the most sought after food at the conference. 

Datarella supported the organizational DAHO.AM team with looking for speakers, defining workshops and also with the more nitty gritty detail of a conference. Additionally, we launched our latest blockchain product at the conference, a cryptocurrency wallet, the XSC Wallet.

When opening the XSC Wallet, each DAHO.AM visitor got 1,000 XSC that enabled her to buy a t-shirt, a goodie bag and a frozen yogurt. Due to the tough conference schedule and summery temperature, many visitors asked other visitors who weren’t interested in goodie bags, to send them their XSC enabling them to buy another froyo. Sending and receiving crypto with tye XSC Wallet proved to be so easy that even the least technically educated (their words) experienced no problem at all managing their cryptocurrency.

Some visitors were hesitant to spend their XSC in the first instance, since they belong to the #HODL group – users who don’t spend their frypto but “Hold On for Dear Life”. But, after the Crowdstart team assured them that they woult get the same amount of XSC tokens they’d spend later this week in real ERC20 XSC tokens that are tradeable on the Ethereum mainnet, they went on a shopping tour.

The fascinating result of the XSC Wallet launch was the fact that all users were completely surprised how easy it is to pay for goods and food  with crypto  in real life. The payment process is easy to understand, fast, and makes so much fun that many visitors returned several times to the Crowdstart stand only to use the XSC Wallet and pay for stuff, again. For the Datarella team, this wasn’t really a surprise, but a very nice confirmation of our strong belief that crypto will play a major role in global payments soon.

Announcing the CSC Cryptocurrency Payment App for DAHO.AM Tech Conference

CrowdstartCoin

We are very pleased to announce that Crowdstart Capital will be releasing a CrowdstartCoin XSC powered payment app and DApp browser at the DAHO.AM tech conference.

DAHO.AM Registration

We want Crowdstart Coin XSC to be THE token for blockchain developers. It goes without saying that you have to store your XSC somewhere and you want to be able to DO something with that XSC right? Our upcoming app hits both of these targets.

No Event Tickets

Since we’re co-organizing the DAHO.AM deep tech conference we thought it would be really cool if we could digitalize the payment process for all the concessions this year.  Usually, you go to a conference and along with your tickets you get a few paper vouchers to trade for food and drinks free of charge. That works but it’s not much fun. DAHO.AM is the home of the future so we’re going to tokenize this old-school process!

This year instead of getting paper vouchers we’ll issue XSC to the developers and techies attending the conference. After downloading the iOS or Android app from the respective app store, DAHO.AM attendees will be able to enter their ticket number and automatically get XSC credited to their account.

bratwürst

After that, you just walk over to buy Bratwürstl, scan a QR code, approve the transaction with your fingerprint and chow down! For the conference, we’ll be deploying a private permissioned network to handle all the conference payments without the need to pay for gas costs.  Afterward whatever XSC you haven’t spent will be credited to your mainnet account.

The CSC app will also include a built-in DApp browser! This will enable DAHO.AM attendees to use our new CROWDVOTE DApp to vote for the most innovative projects at the conference on the ethereum blockchain using the very same app.  Our smart contract will tally the votes and automatically award XSC to the winners at the end of the conference.

Part of why we’re so excited about the DAHO.AM conference is that it presents an opportunity to get really hands-on with blockchain technology and really see what can be accomplished in the real world.  We’re looking forward to seeing you there. Click here to reserve your tickets now!

A Guide to Trading CrowdstartCoin XSC on EtherDelta & ForkDelta

EtherDelta

We’ve gotten many requests for a clean step by step guide on how to buy and sell CrowdstartCoins XSC on EtherDelta and ForkDelta. Decentralized exchanges are awesome but often hard to use. We want to improve this with our trading guide.

There are two ways to get XSC, either you create value for the advancement of the blockchain ecosystem and receive XSC as a reward or you buy XSC in the open market. In the initial phase, we at Crowdstart Capital determine who receives XSC but we are hard at work on the CrowdVote DAPP which will allow XSC holders to directly and decentrally decide who deserves XSC for their contributions to the blockchain ecosystem.

This guide is for everyone. Regardless of whether you want to buy XSC to use in our upcoming CrowdVote DAPP or you have received XSC as a reward and want to sell, this step by step guide will show you the way.

What are EtherDelta and Metamask?

As most of you know, EtherDelta is a decentralized trading platform for Ether and Ethereum-based tokens. Many of you may also be familiar with the EtherDelta fork ForkDelta. The latter offers an offchain orderbook but is otherwise functionally identical to its parent, Etherdelta. For this reason, our guide can currently be used for both exchanges. This could change in the future as ForkDelta is planning upgrades to the user interface.

XSC is traded on four decentral exchanges at the moment. Decentralization means that your funds are held in a smart contract so that you are the only person who can deposit, withdraw or trade. This doesn’t require trusting an administrator or any centralized service provider. This also means that there’s no password reset and no undo button.

There’s a huge variety of different wallets out there with which you can send, receive or save your funds but the safest and most user-friendly way to interact with decentral applications is by using the MetaMask-extension. That’ll be our first step. MetaMask offers a secure identity vault allowing for easy management of private keys and for the signing of blockchain transactions without exposing your keys directly in the DAPP.  If you already have the MetaMask-extension installed or decided to go without it you can skip the following step.

Set Up MetaMask

The MetaMask extension is available for many browsers like Mozilla Firefox, Opera or Chrome. In this documentation, we use the extension for Google Chrome. To add the MetaMask extension to Chrome you can use this link. By clicking on “add to Chrome” the extension should be visible on the top right of your browser, right next to the URL field.

MetaMask extension installed

After clicking on the extension and accepting the terms of conditions you can now import your existing account or create a new one by setting a new password that you won’t forget. (There’s no password reset functionality here by design.)

Create MetaMask Account

At this point, MetaMask informs you that your vault was created and gives you 12 random seed words which you need if you want to restore it or to transfer your account into other wallets or devices. Save these words somewhere safeand secret, e.g. write it down on a piece of paper and store it securely. After you’ve done this, click on “I’ve copied it somewhere safe” in order to continue.

Metamask seed words

Now you have your first MetaMask-vault. If you received XSC in another wallet you may want to import your tokens into Metamask. To import a wallet into MetaMask you’ll need your private key or your JSON keystore file. To do this click on the account settings as shown in the following screenshot and click on “Import Account”.

Import account to MetaMask

In the next step either select “Private Key“ or „JSON File“ in the dropdown and enter your private key or import your JSON file. If you use a private key it should look like shown in the next screenshot. Finish importing your account by clicking on „Import“.

MM enter private Key

As you can see MetaMask created a new account (Here: Account 2) which contains your funds. Your wallet is now successfully synced with MetaMask. At this point, you need to add the Crowdstart Coin (XSC) contract address so you can see your tokens both in MetaMask and on EtherDelta. To add a token, click on the tab „tokens“ on the button and click on „add token“.

MetaMask add token

To successfully add a token you need the token contact address, the token symbol and the decimals of precision. We’ve included these details below so you can just cut and paste.

XSC Contact Address: 0x0f513ffb4926ff82d7f60a05069047aca295c413

Token symbol: XSC

Decimals of Precision: 18

If you entered the contact address successfully it should look like this:

MetaMask XSC token details

After adding your XSC and syncing your wallet, your MetaMask account will now display your tokens like this:

MetaMask display XSC

Now you can safely and securely trade with EtherDelta.

Import Your Wallet Into EtherDelta

If you use MetaMask, the wallet is already synced and you just need to select your preferred account in the dropdown as shown below.

EtherDelta Import Wallet from MetaMask

If you don’t use MetaMask you need to import your file using your private key. To do so click on the upper right corner to „Select account“ and „Import account“ in the dropdown menu.

EtherDelta Import Wallet

Afterward, EtherDelta asks for your wallet information. In the first input box, you need to enter your public key while your private key belongs to the second input box. The private key is stored locally in your browser and is not communicated to EtherDelta or stored on any server. That said, this login method is generally considered as risky due to the fact that many phishing sites pose impersonate EtherDelta. If you enter your private keys somewhere malicious it’s game over. For this reason, we vastly prefer MetaMask. If you want even more security you can use a Ledger hardware wallet but that’s beyond the scope of this guide.

EtherDelta Enter keys

After clicking on „Import account“, EtherDelta displays your account like this:

EtherDelta after import not MetaMask

Trading XSC

After your wallet is imported and synced to EtherDelta it’s time to trade XSC on EtherDelta. This chapter will describe the process in detail.

First of all, you need to tell EtherDelta that you want to trade XSC. To do so, you need to click in the dropdown in the top middle of the page and select XSC as shown. After selecting XSC the page reloads and shows the dashboard for XSC to ETH trades.

EtherDelta select XSC

Deposit ETH to the Smart Contract

In the account dropdown (upper right), next to the account address is your wallet balance. If your wallet balance is 0 you need to send some ETH to that wallet. Do that before proceeding to the next step.

Now that you have some Ether in your wallet, you need to deposit from your wallet to the EtherDelta smart contract to start trading. By doing this the funds will be available to any purchase at EtherDelta.

In the upper left, there is a “Balance” panel as shown below. There are three columns, “Token,” “Wallet,” and “EtherDelta.” The first column, “Token”, will have a row for XSC and a row for ETH. The “Wallet” column shows the balance held in the account you have selected in the account dropdown. Notice that the balance shown in the ETH row under “Wallet” matches the balance shown in the account dropdown.

EtherDelta Balance

When you deposit, you will move funds from your “Wallet” to the EtherDelta exchange smart contract. To do this, enter the amount you want to deposit and press “Deposit”. Don’t deposit all of your ETH though. You need to leave some behind in your “Wallet” to cover gas fees. A good rule of thumb is to leave 0.05 ETH in your “Wallet” to cover gas fees for future transactions you will do (trading, depositing, withdrawing).

EtherDelta Deposit ETH

After you press the “Deposit” button, if you’re using MetaMask you’ll have a transaction to approve. You can reduce the gas price from the default (~4 gwei) if you’re willing to wait longer for your transaction to confirm but pay a lower fee. It’s generally a good idea to check the gas prices at ethgasstation and use either the standard price or the safe low price listed there. If you’re not using MetaMask, you can set the gas price from the “Gas price” item in the account dropdown (upper right). If you are depositing a token (not ETH), depositing will involve two back-to-back transactions. The first one approves the EtherDelta smart contract to transfer the deposit on your behalf. The second one is the actual deposit. You must approve both.

EtherDelta Deposit ETH to smart contract

After your transaction has been sent, EtherDelta will tell you that you generated a transaction. You can click the link to track your transaction on Etherscan.io.

EtherDelta Deposit ETH transaction

Once your transaction confirms, you should see funds move from the “Wallet” column to the “EtherDelta” column. In our case, you can see that the “Wallet” column reduced by 0.005 while the “EtherDelta” column raised by 0.005.

EtherDelta Deposit ETH afterwards

Withdraw ETH

The Withdraw tab is the opposite of the Deposit tab. It will move funds from the “EtherDelta” column back to the “Wallet” column. Remember that in order to withdraw, you need to pay a gas fee, and the gas fee comes from your “Wallet.”

Transfer

If you want to transfer your tokens then the “Transfer” tab is for you. The Deposit tab moves funds from your wallet to EtherDelta. The Withdraw tab moves funds from EtherDelta to your wallet. The Transfer tab moves funds from your wallet to another wallet address. If you want to “withdraw to another Ethereum address,” you need to withdraw and then transfer.

On the Transfer tab, the first box is the amount you want to transfer. The second box is the address you want to transfer to. By default, the address you want to transfer to is pre-filled in with your existing address. Overwrite this with another address of your choice and then press “Transfer.”

Buying XSC

You have now accomplished the last step needed to trade XSC by depositing ETH to the EtherDelta smart contract. To buy XSC you need to place a buy order in the order book panel in the center of the EtherDelta interface.

You can choose which way you want to buy your XSC tokens. One option is to post a new buy order to the order book and wait for someone to fill the order. This method requires no fees at EtherDelta. On the other hand, you can choose an existing sell order to buy the XSC at a price already offered in the order book. This method has the advantage of executing immediately. 

Placing a Buy Order

If you don’t want to trade immediately or don’t like the prices you see in the order book, you can place your own order. To place a buy order you need to click on the “Buy” tab in the “NEW ORDER” panel. There are 4 input boxes to fill. The first is how many XSC you want to buy (in this example 10 XSC). The second describes at which price you want the XSC to be purchased (here 0.0005 XSC/ETH). The next box is filled automatically depending on your entries above. So in our case, the transaction would cost 0.005 ETH. The box “Expires” describes the timeframe in blocks that your order is being active. The EtherDelta timeframe is based on ether blocks, which means that each block takes about 14 seconds. A 10000 block limit should last about two days.

EtherDelta place XSC order

After clicking on “buy” EtherDelta adds your order to the order book and will inform you via two notifications. One says “You sent an order” the second one will say “Your order was received”.

Prompt order placed

Don’t panic if the order isn’t shown immediately in the order book, it can take up to a minute. From now on you can see your order highlighted blue in the “order book” and in the “MY TRANSACTIONS” panel under the tag “Orders”. Your balance will not change when you place an order, it will only change when your order is executed.

If your order was successfully executed, you can find the order in the tag “trades” together with a link to the transaction on Etherscan.io as shown:

EtherDelta confirmation order

You can also cancel your order if you want to. Go to the “MY TRANSACTIONS” panel in the lower center of the EtherDelta interface and go to the tap “Orders”. Here you can click on “Cancel” which triggers a new transaction.

EtherDelta cancel order

Buying a “Sell” Order

As mentioned above, you can buy XSC by buying a sell order. You can find the sell orders in the order book panel in the upper center of the EtherDelta interface. Here you can see buy offers, which are green, and sell offers, which are red. Both of them show the price where they are willing to buy or sell, the amount of XSC they are willing to trade and the total amount of ETH that this transaction would cost. The orders are ordered depending on their price. If you want to buy ether, look at the lowest sell order (the red ones) to get the cheapest price.

EtherDelta Buy sell order

Now just choose your preferred sell order by clicking it. EtherDelta will then open a new dialog to confirm your purchase.

EtherDelta Buy from sell

As you can see in the dialog, you can buy less XSC than offered. So it’s up to you if you want to buy all XSC offered or less. Keep in mind that the more XSC you buy, the higher the value of the transaction.

Click on “Buy” if you entered your preferred amount of XSC to buy. After this, your transaction will be triggered. As in the steps before, EtherDelta will provide a link to the transaction on Etherscan.io to track the transaction. After a few minutes, you should see your XSC in your wallet.

Deposit XSC to EtherDelta

If you have XSC in your wallet you can sell them on EtherDelta as well. It is basically the same process as buying XSC, just the other way around.

So in the first step, you need to deposit XSC to the EtherDelta smart contract. You are doing this by entering the amount of XSC that you want to deposit in the “Balance” panel on the upper left in the interface. In our case, we want to add 10 XSC to the smart contract.

EtherDelta deposit XSC

Once again, set the gas price on the MetaMask dialog that will prompt and confirm the transaction by clicking on submit. This will once again trigger a transaction and an etherscan.io link to track the transaction will be provided.

MetaMask deposit XSC

After your transaction was successfully executed, you can see the chances in the “Balance” panel and on your MetaMask account.

Selling XSC by Creating an Order

Now that there are XSC on the EtherDelta smart contract you can create a sell order. Therefore go to the “New order” panel in the lower center of the EtherDelta interface and click on the “sell” tab. Now you can enter the amount of XSC you are willing to sell and set a price at which you want to sell each XSC. Here we want to sell 10 XSC at the price of 0.03 XSC/ETH. The box “Expires” describes the timeframe in blocks that your order will be active. It’s the same as with a buy order in that a 10000 block limit should last about 2 days. Finally, click on sell to publish your order to the order book. MetaMask will ask you to confirm the transaction by signing it.

MetaMask sign sell XSC

Now you can see your order in the “MY TRANSACTIONS” panel in the tab “orders” as shown below.

EtherDelta show order

Selling XSC by Choosing Buy Order

The second option is to sell XSC by selecting an already existing buy order. You can find the buy orders in the “ORDER BOOK” panel in the upper center of the EtherDelta interface. To sell your XSC you need to look at the green offers in the order book. The first green order from above represents the highest price that somebody is willing to buy your XSC.

EtherDelta order book sell XSC

Now just choose your preferred buy order by clicking it. EtherDelta will then open a new dialog to confirm your transaction.

EtherDelta sell from buy

As you can see in the dialog, you can sell less XSC than offered. So it’s up to you if you want to sell all the XSC the buyer wants or less. As you can see, there are no fees because you sell your XSC. Confirm your transaction by clicking on “sell”.

After this, your transaction will be executed. Like in the steps before, EtherDelta will provide a link to the transaction on Etherscan.io to track the transaction. After a few minutes, you should see the changed value in your wallet.

Happy trading!

CROWDVOTE – A Community Driven Decision Making Model To Compensate Blockchain Developers

CrowdstartCoin

Big news is coming up at Crowdstart: with CROWDVOTE we will provide a community driven opinion forming and decision making model that follows on the present centralized distribution model of CrowdstartCoins XSC.

Starting with our IOTA hackathon in Gdansk, in November 2017, we have distributed CrowdstartCoins XSC to over 2,000 developers who have added valuable code to the blockchain ecosystem. As promised, we at Crowdstart do not think that we are the best people to decide who is eligible to receive CrowdstartCoins XSC, but rather it should be the responsibility of the entire blockchain community to form opinions and make decisions that define the distribution of XSC.

CROWDVOTE to be launched at DAHOAM Tech Conference
We announced our plan of developing a liquid democracy model to enable that kind of a decentralized decision making process last November. Today, we are very happy to announce that we will launch the first version of CROWDVOTE at DAHOAM Tech Conference, on July, 24.

With CROWDVOTE, members of the blockchain community will be able to propose and vote for blockchain projects supporting them to receive their deserved CrowdstartCoins XSC. In the first version, there still  will be some centralized elements; e.g. there will be a set of rules that define the proposal and voting mechanism. A framework of rules has to be implemented from the start – otherwise the model would create more confusion than joy about the new decision making opportunities. Our plan, however, is to go further and also decentralise these aspects. In future versions of CROWDVOTE, the community will be able to define the rules for proposing and voting for projects by themselves.

Want to participate and help CROWDVOTE to be developed?

If you are generally interested in decentralise decision making processes and liquid democracy, please feel invited to participate and support the development of CROWDVOTE. Send us an email to crowdvote (at) crowdstart (dot) capital.

 

Phishing Attempt Using CrowdstartCoin Fake Twitter Account

CrowdstartCoin

Yesterday, it was brought to our attention that someone hs been impersonating our @CrowdstartCoin Twitter account using the handle „Crowdstart_Coin“ (with an underscore).

This fake account is ha,rd to distinguish from the real one since it‘s not only using a very similar heder but has been copying some of our original tweets. This account asks you for visiting a google form on which you are asked to send Ether to a specific address.

We at CrowdstartCapital would never ask anyone to send Ether to a soecufic address. We distribute our CrowdstartCoin to developers who add valuable code to the blockchin ecosystem.

Please be careful with all things crypto – especially if someone asksyou to provide your private key or to send crypto to an address.
